What Will You Learn?

  • Learn how to discern science-based information from gardening myth.
  • Discover how science provides the best information for developing a sustainable garden.
  • Review how to inspect a tree or shrub to determine its physical condition.

Course Overview

Where do you turn for gardening information? To the salespeople at your local home-improvement store? To the “expert” who has never lived in your part of the country? To the Internet with its latest 100%-effective home remedy pest-control mixture? If those are your sources—and they are for so many home gardeners—chances are you haven’t been entirely satisfied with your results. That’s because so many gardening “how-tos” are simply wrong for your particular garden, while other well-established “how-tos” are wrong for the long-term health of any garden.

The Science of Gardening shows how to create a beautiful and sustainable home garden guided by the newest information from applied plant physiology, biology, soils science, climatology, hydrology, chemistry, and ecology. From choosing and purchasing your trees and shrubs, to giving them the best start in your garden, to healthy maintenance and pest control, award-winning horticulturist Linda Chalker-Scott of Washington State University shows why science-based decisions are always best for your home garden, and also the most ecologically sound for the greater environment. You’ll enjoy her contagious enthusiasm and wonderful sense of humor as you learn to create your own vibrant, sustainable landscape.

In these 24 lectures—enhanced with beautiful photographs, videos, and illustrations both in the studio and in the field—you’ll learn how to:

  • Assess your site’s topography, microclimate, and soil chemistry before choosing a tree or shrub species, and understand why that information is crucial to long-term success.
  • Inspect nursery plants from the crown to the ground for evidence of quality and health.
  • Estimate a specimen’s root health based on above-ground clues.
  • Water your landscape effectively and appropriately, with conservation in mind.
  • Choose an appropriate mulch type by understanding the science-based pros and cons of each.
  • Prune your trees and shrubs safely and effectively based on their morphology and physiology.
  • Identify plant stressors and predict future problems.
  • Manage the weeds and pests in your garden without immediately turning to herbicides and pesticides.
  • Choose trustworthy sources of plant-science information, keeping in mind the critical difference between correlation and causation.

Integrated Pest Management

Professor Chalker-Scott covers gardening from soil and seed to pruning and produce, focusing on the issues and obstacles every gardener faces. And every garden has pests, whether weeds, animals, or both. And let’s be honest: Some days it’s pretty tempting to just buy that bottle of pesticide to solve what feels like a never-ending problem. But building a beautiful landscape doesn’t happen overnight, and neither does pest control. Your safest and most effective long-term approach is to develop an integrated pest management (IPM) plan that addresses your plant and soil needs, the biology and needs of the pest, your tolerance level for garden intrusion, and concern for the surrounding environment. Professor Chalker-Scott devotes two full lectures to pesticides and pest treatment as very few home gardeners are familiar with diagnosing the issues and the options available to them.

The Science of Gardening provides a four-pronged approach for understanding and managing pests of all kinds—from English ivy to deer and everything in between. Your first step is to accurately identify the pest and its physiology, food requirements, and reproduction. With an IPM, the gardener then considers four categories of action in the following order: cultural, mechanical, biological, and chemical. Cultural options include making the plant or the environment less hospitable to the pest. Mechanical options can include weeding, fencing, water blasting, or traps. Biological control requires a deep knowledge of the species involved and careful planning to avoid inadvertent consequences that are worse than the initial problem. And if do you need to turn to chemicals as a last resort, this course gives you a step-by-step guide to choosing and using the appropriate chemicals in the safest manner.

Busting the Myths of Home Gardening

Professor Chalker-Scott describes today’s gardening world as a “Wild West” of products and practices that exist in an almost regulation-free environment. Consequently, we need to look for supporting scientific evidence before making decisions with far-ranging effects.

Understanding the physiological and chemical mechanisms by which your tree or shrub interacts with its environment is crucial for determining how to support the health of your garden. You’ll learn how and why your plants rely on bacteria and fungus in the soil—and how the application of unnecessary gardening products can disrupt those crucial pathways. You’ll also learn why some species of plants grow exceptionally well with certain fungi, forming a symbiotic relationship where the chemical products of one become the nutrients of the other.

As you learn more about science-based gardening, you’ll be empowered to bust some long-term gardening myths. For example, you might have heard you should never shop at a nursery where some plants show evidence of insect damage. The truth: If there’s no insect damage on their plants, it most likely means they’ve been using far too many pesticides. And what about native plants? They will always do better in your garden than non-natives, right? Probably not, because unless you live in the middle of a completely undeveloped area, your garden today shares very few soil, water, and microclimate characteristics with the environment in which that native species developed.

In The Science of Gardening, you’ll learn the truth behind many longstanding myths surrounding gardening. At best, they are wasteful. And at worst, they’ll harm your plants and the environment. They include well-meaning but inaccurate advice such as:

  • Always put gravel in the bottom of a pot because it helps with drainage.
  • Never disturb the root ball of a tree or shrub you’re planting.
  • Use fertilizers when you plant bulbs, perennials, trees, or shrubs.
  • Use organic fertilizers because they’re safer than synthetics.
  • Your soil should contain a great deal of organic matter, otherwise it won’t be healthy.
  • Use a vitamin B-1 supplement because it enhances root growth.
  • Choose only mulches containing organic materials If you want the mulch to be effective.
  • Replace your turf with xeriscape; it will always save you water.
  • Apply a wound dressing after branch removal to help the tree heal.

When scientists examine home gardens and landscapes, one fact stands out: The leading cause of landscape failure is not disease and it’s not pests—it’s our own gardening practices. The Science of Gardening shows you how to make the best possible decisions on plant selection, planting, and maintenance. From now on, you won’t need a green thumb to get your garden to grow; you’ll have science on your side!

  • 1
    Garden Science: Weeding Out the Myths
    How many of your horticultural practices are based on anecdotal evidence from your neighbor or grandmother, and how do you assess their validity? In the midst of an unregulated “Wild West” of gardening products and practices, you can learn to access science-based information to create your sustainable dream garden. x
  • 2
    Site Analysis: Choosing the Right Spot
    Many of us make our landscape choices based on plant aesthetics. Instead, learn to first identify your location's topography, prevailing winds, hydrology, soil type, and other environmental factors. Then you'll be able to choose a plant well-suited for the long term. And you'll avoid season after season of frustration. x
  • 3
    Soil Analysis: What Makes Soil Great?
    Unless you live in a completely undeveloped area, chances are your home garden soil is not native. Learn what makes a “great” soil and how to determine your own approximate amounts of clay, silt, and sand; texture; nutrients; pH; and more—before you purchase that “must have” soil addition from the gardening store. x
  • 4
    Living Soils: Bacteria and Fungi
    Just as humans cannot grow without our supportive microbiome, neither can plants. Plant roots, bacterial sheathes, and long filaments of fungus all function together to support the plant's growth, enhancing the uptake of water and nutrients and improving soil structure. But what happens to this crucial symbiosis when you add unnecessary fertilizers? x
  • 5
    Plant Selection: Natives versus Non-Natives
    Native plants are always a better home-garden choice than non-natives, right? We know they are best suited to thrive in the soils and ecosystems of the area, and will create the best wildlife habitat. But does garden science support those “truths”? You might be surprised to learn how introduced species can enhance your garden and landscape biodiversity. x
  • 6
    Plant Selection: Function and Form
    In addition to its aesthetic value, your landscaping can provide privacy, protect soils from erosion, moderate temperature, manage storm-water runoff, provide wildlife habitat, and more. Learn how to select the appropriate plants with respect to morphology, growth rates, and physiology to help achieve your specific goals for various locations on your property. x
  • 7
    Plant Selection: Finding Quality Specimens
    Half the battle of successful landscaping is starting with the healthiest specimens—not, as we sometimes prefer, the largest. Learn how to inspect nursery plants from the crown to the ground for evidence of quality and health, and how to estimate root health by checking for suckers on single-trunk trees, root flare, surface roots, and the “tippy test.” x
  • 8
    Soil Preparation and Protection
    “Don’t plant before you fertilize!” Chances are you’ve heard that admonishment more than once. But gardening science has revealed that many popular practices—including fertilizing every time you plant—are neither necessary nor sustainable. Learn about a more natural way to add organic material to your garden to protect soil structure and nourish your plants. x
  • 9
    The Truth about Mulch
    Learn about the wide variety of mulch types—from glass to wood to compost—and the science-based pros and cons of each. By considering your specific site conditions and personal aesthetics, you can blend a variety of mulches to transform a struggling landscape into one that’s healthier and more sustainable. x
  • 10
    Planting for Survival
    Current research supports the need to radically change the way we’ve been planting trees for the past half century. Although considered controversial by nursery professionals, learn why plant science supports the “old” method of bare-root planting. This technique can improve tree survival because a vigorous root system will better support a healthy crown. x
  • 11
    Aftercare for New Plants
    Once your new plant is in the ground, how should you take care of it? Learn the basics of watering, mulching, fertilizing, staking, and pruning newly transplanted trees or shrubs—and why this care might change in subsequent seasons when the plant is well established. Not sure if your newly planted tree is experiencing healthy root growth? Try the wiggle test. x
  • 12
    Plant Nutrition: Evidence-Based Fertilizing
    The goal of fertilizing is to match your soil and plant needs—micro- and macronutrients, and other chemical requirements—with the appropriate sources of nutrition. By understanding your specific soil test results, you can determine which nutrients are deficient, which might already be present in toxic quantities, and whether or not to buy organic. x
  • 13
    The Art and Science of Pruning
    Have you ever seen a tree cut painted with tar or another sealant? Or seen a crown chopped completely bare? Both are common practices that we now know are harmful to the plant. Using applied plant physiology and science-based guidelines, learn the best timing and methods for pruning that will lead to healthy tree growth for the long term. x
  • 14
    Creating Safe Food Gardens
    While it seems intuitive that vegetables grown in your home garden will be safer and healthier than those purchased at the supermarket, that could be a dangerous assumption. Does your garden soil contain elements of concern, especially cadmium or lead? If so, learn how to best respond—whether in plant choices or creative garden design. x
  • 15
    Water-Wise Landscaping
    Learn how to reduce water use and protect water quality using knowledge of plant biochemistry, transpiration, and photosynthesis. Designing garden modifications, choosing appropriate plants based on morphology and color, and incorporating shading and mulch to reduce evaporation are just some of the water-wise techniques that will help conserve water. x
  • 16
    Diagnosing Diseases and Disasters
    The most common cause of death for home garden plants is poor horticultural practices, not disease or pests. With this step-by-step guide to diagnosing plant problems, you’ll learn how to appropriately remedy any problem—and when the plant will heal on its own. You’ll also be able to identify the warning signs of future problems, so you can treat the issue before it’s too late. x
  • 17
    Gardening CSI: Case Studies
    Take a virtual field trip to see examples of unhealthy plants and learn how to diagnose their problems based on the science of plant physiology. You'll see tree girdling, plants that become smaller over time instead of larger, scorched shrubs, and more. Once you understand the physiology behind these problems, you'll be better able to diagnose and treat any of your garden's plants that might be failing. x
  • 18
    Integrated Pest Management
    There is no lack of chemicals to get rid of the pests in your garden—whether that pest is a plant, insect, or other organism. But for long-term health, integrated pest management provides a better, systematic, science-based approach with a minimum of chemical inputs. With IPM, the goal isn’t to eradicate the pests, but to identify your tolerance level for their presence and implement appropriate management techniques. x
  • 19
    Understanding Pesticides
    Yes, there can be an appropriate time for judicious use of chemical pesticides in your garden—as a last resort to solve specific problems. Learn why you should always stick with those approved by the EPA and your state department of agriculture, and never use the home remedies promoted on the Internet or in non-science-based books. Are organics always safer ecologically than synthetics? You’ll be surprised. x
  • 20
    What to Do about Weeds
    If you have a garden in the U.S., chances are you're familiar with the damage caused by English ivy, kudzu, purple loosestrife, and/or the tamarisk tree. Each of these hardy plants can quickly create a monoculture, driving out other plant species and limiting the availability of diverse animal habitat. Learn the best science-based mechanisms to control these plants. x
  • 21
    What to Do about Insects
    Before you resort to chemical sprays—which can kill all insects, not just the pests you’re targeting—learn how to manage insects by increasing plant diversity, establishing “trap” plants, and using repellents and tools including your basic garden hose. But before you do anything, know your “enemy.” Understanding the life cycle and reproductive physiology of the insect will help you make the most effective management choices. x
  • 22
    What to Do about Herbivores
    You could spend a lot of money trying to keep slugs, rats, moles, rabbits, squirrels, deer, and other herbivores out of your garden. But most of those purchases would have little, if any, value, especially if feeding pressure is high in the surrounding habitat. Learn about the few options that are both safe and effective. And remember, “man’s best friend” might be your garden’s best friend, too. x
  • 23
    Tackling Garden Myths and Misinformation
    If you can't trust the Internet home remedy or the local gardening salesperson, whom can you trust? Make science-based gardening decisions by assessing the credibility, relevance, accuracy, and purpose of the information you read. Learn to understand the significant role played by peer review, the crucial difference between correlation and causation, and how to watch out for over-extrapolation and misapplied science. x
  • 24
    Applied Garden Science: Success Stories
    Two specific transformation stories—a wetlands restoration and a home garden project—reflect the benefit of science-based planning by considering soils, temperature, sunlight, moisture, water table, and likely pests. Learn how to become a citizen scientist and contribute to the field, not by looking for the easy way out, but by asking the hard questions and knowing how to assess the strength of the answers. x

The Science of Gardening is rated 4.5 out of 5 by 60.
Rated 5 out of 5 by from Myth busting! This course was worth it for the mythbusting alone! There are so many non scientific ”common knowledge” practices that actually harm rather than help. I consider myself an experienced gardener and I have changed several practices and gotten a soil test at a lab after taking this course. Now I know why the bareroot seedling trees I have planted have done so well as opposed to the nursery bought containerized trees. Thanks for the excellent course!

Rated 5 out of 5 by from Tons of helpful information I'm slowly working through the videos, but have really enjoyed every one so far. Dr. Chalker-Scott is a great instructor. She not only gives loads of helpful information but explains the reasons behind everything. I've been an amateur gardener for years, but I'm learning new things with each lesson.
Date published: 2019-03-01
Rated 5 out of 5 by from Hair-raising and in depth This is the most informative source I’ve seen for what actually happens in the soil and what soil is. It was also disturbing to contemplate how industrial farming disrespects the natural process. I’ve not finished the course, but I so look forward to it. As to delivery, I don’t think Dr. Chalker-Scott talks too fast, although she has an annoying habit of looking into one camera and then obviously turning a quarter turn the other way to a different camera and a slightly nasal voice, but these are very very minor distractions. The setting is beautiful, full of plants and beautifully lighted, there are short videos and text overlays to emphasize points, and she has a demonstration table with samples of what she’s talking about. I love this course!

Rated 5 out of 5 by from Science of Gardening I am only 4 sessions into the class but I really enjoy the class so far. Very informative and a good knowledgeable instructor who presents the material in layman’s terms. I have killed more plants then I have ever got to live, so this class is very helpful to me. Would like to see another class in hydroponics.
Date published: 2019-02-15
Rated 1 out of 5 by from Definitely deep into the science of botany I bought this about a month ago and have watched three lectures. Thus far I have gleaned very little pragmatic advice about gardening. I was hoping to get a foundation for starting a small vegetable garden that I could plant with our grandchildren. As a child and adult I have planted many gardens but I wanted to get some techniques that I could share with the grandchildren. Thus far I am extremely disappointed with this course. I should have read the synopsis better.

Rated 5 out of 5 by from So far I’m loving all three courses Gardening, cooking, Spanish. I’m very impressed! University quality lectures...and I have a doctorate, so I can tell. I’m loving them!
Date published: 2019-01-23
Rated 1 out of 5 by from Not what I expected One of the worst courses I've ever taken. Talks too fast, repeats self throughout the same lessons and all lessons so didn't learn more than what could have fit inside three courses
Date published: 2019-01-17
Rated 5 out of 5 by from Very informative! I love this course! It's user-friendly and provides good "hands on" demonstrations and explanations. It's eye-opening to learn how many gardening practices are not based on science and of great value to learn the evidence-based practices that are best to use. I am going to recommend this course to many other gardeners!
Date published: 2019-01-14
Rated 5 out of 5 by from 5-7 courses In general, informative and good speakers. Especially Robert Greenberg and his music courses. They are wonderful.

Rated 5 out of 5 by from Very Informative I have really enjoyed this course! The speaker is well spoken and I learned from her lectures! What was really neat was that she reference the Museum of the Shenandoah Valley and VA State Arboretum--I live in the Shenandoah Valley and have been to both! This is my first course with Great Courses, but it won't be my last!
Date published: 2018-11-17
Rated 5 out of 5 by from Through coverage with many demonstrations. I am actively using concepts from this course in my yard. I’ve also discussed some of the instructor’s assertions with other knowledgeable people. This course was very worthwhile.

Rated 5 out of 5 by from Green Thumb Demystified! “The Science of Gardening” is a visually beautiful course. The brief music-and-video intro (with time-lapse photography of blooming plants) is very pleasant at the beginning of each lecture. Other highlights include: 1) Dr. Linda Chalker-Scott’s tips on what to look for when purchasing plants from a nursery should save one time and money; 2) Her “Integrated Pest Management” advice, particularly as pertains to insects, seems sensible; 3) Effective pruning practices are clearly demonstrated; 4) Lecture Five discussing native vs. non-native plants is especially enlightening; 5) Lecture Fourteen about minimizing exposure to identifiable soil contaminants is a welcome eye-opener; 6) The professor’s general attitude about plants and their care is inspiring, and she sets an example of mindfulness that I feel sure can benefit all gardeners, whether or not they choose to follow every one of her specific instructions; and 7) “Applied Garden Science,” the concluding lecture, is full of success stories, plus an invitation to everyone to be a wise and inquisitive “citizen scientist.” So much of the gardening advice that I have received during over sixty years has been anecdotal, pitched by salespeople, or even mystical. Dr. Chalker-Scott’s course is convincingly science-based. The professor is erudite, thorough, methodical, and encouraging. I appreciate her recounting how, as a gardener and landscaper on properties in different North American locales, and as a working consultant, she solves specific horticultural problems for her own family and for clients. Her sharing of experiences as a university instructor, too, nicely merges practical and theoretical information. The course includes many actual demonstrations in the lecture studio as well as “in the field.” Dr. Chalker-Scott can be described a “myth buster.” I do not doubt that some in her audience will find her approaches to gardening novel and surprising. She seems very confident with what she has learned through her own and others’ scientific research, though, and that confidence has “rubbed off on me.” I feel eager to try out her recommendations in my yard and vegetable garden next Spring. There are a few aspects of this course which could be handled better: 1) The professor tends to speak too quickly; 2) In a related issue to rapid speech, labelled visual accompaniments sometimes stay on-screen too briefly; 3) Some technical terms should be defined either verbally or in the guidebook—one can, of course, retrieve the spellings from a transcript book or the closed captioning; but there are many sophisticated terms in this course, and looking them up on the Internet after each lecture can be time-consuming; 4) More close-ups should be included in the generally good videography; 5) One fifteen-second transitional video clip is repeated so frequently, multiple times during some single lectures, as to become merely annoying.
Date published: 2018-11-02
Rated 5 out of 5 by from Love It This course is informative and enjoyable. I recommend it to those who wish to increase their knowledge of the plant world.
Date published: 2018-10-20
Rated 5 out of 5 by from Excellent Course The talks on how to properly plant trees and scrubs and the truth about mulch was more than worth the price of this course. I have been doing so many things wrong for far too long such as over fertilizing, rototilling and planting new plants with the clay ball attached. Already today, I trimmed a branch rather than spraying the tent worms. Linda Chalker-Scott is passionate about landscape and any gardener should benefit from this course.
Date published: 2018-10-18
Rated 5 out of 5 by from The Science of Gardening Dr. Chalker-Scott's debunking of commercial agricultural methods that are unwisely applied to home gardening was insightful and useful. I tested all my recently planted trees using her " wiggle" approach and found them to be properly rooted.
Date published: 2018-10-01
Rated 5 out of 5 by from Excellent information on soil preparation This video has provided a wealth of information on how to prepare soil before planting as well as how to take care of plants after planting.
Date published: 2018-09-11
Rated 5 out of 5 by from Very enlightening! I haven't completed all the lessons, yet, but I have found the first 7 or 8 that I've viewed very interesting. I already feel more confident in my gardening knowledge. There things I don't do but thought I should, but have learned they are really things I don't need to do or shouldn't do, so I was right all along! Linda Chalker-Scott presents the material in a way that is understandable. I always learns at least one thing I can use in each lesson.
Date published: 2018-08-04
Rated 5 out of 5 by from Excellent, as I expected! A home gardener, I am continually looking for "best practices," solid and dependable information, so as to have the most success possible and be the most environmentally responsible in my garden. Seeing the ID of the presenter told me this is what I would get and I was not disappointed. In addition, I very much enjoyed the lectures. Dr. Chalker-Scott is a great teacher.
Date published: 2018-07-25
Rated 5 out of 5 by from Very appropriate titlr Excellent course packed with sound, science based gardening advice. It was informative and fun. I would recommend it to anyone who wants to garden sustainably and responsibly.
Date published: 2018-07-23
Rated 2 out of 5 by from Less than average course I have taken over 40 courses from the Teaching Company and this course is by far the least informative and least enjoyable course to date. The professor seems knowledgeable but spends way too much time on live examples and less efficient in general covering the course material compared to other professors. Another thing to note about this course is that although the course is titled "The Science of Gardening," its main focus is on trees and shrubs.
Date published: 2018-07-16
Rated 4 out of 5 by from The Science of Gardening Very helpful course. The material was well presented.
Date published: 2018-07-12
Rated 5 out of 5 by from Exactly what I was looking for I feel like im educated enough to catch my landscaper making mistakes. It cut through the noise and i will go back to important sections again as needed. A real course and mich better than a book. The professor gave demonstrations that can be applied directly.
Date published: 2018-07-12
Rated 5 out of 5 by from After years of seeing volcano mulch, tree bags, hostas in full sun and 7 step lawn fertilizing, it was great to hear gardening subjects presented with common sense and science. I found the myth wsu website previously and it has helped me tremendously over the years. This course was a nice find to enhsnce her work
Date published: 2018-07-11
Rated 5 out of 5 by from Gardening I enjoyed the full content of this course and it was presented fantastically! The examples that were utilized added to the learning experience and made the course even more enjoyable!
Date published: 2018-07-10
Rated 5 out of 5 by from The science of gardening rocks! I waited for this course to come out because Dr Chalker-Scott disappeared from online forums to record it. I was already a fan; I own many of her books. Science-based gardening is solid as opposed to garden club meeting information. The author also lives in my region, Pacific Northwest. If you are a gardener or professional landscaper like me then get this course. It's a must. I guarantee the course will bust at least one myth you still cling to. Once you finish the course, but Linda's books. There may be a second course in the works and I hope it happens soon. I bought the course using a discount code from Fine gardening magazine, I could never pay over $200. I think I paid the regulator $60.
Date published: 2018-07-06
Rated 4 out of 5 by from Appropriate title The course is well balanced as it mixes scientific background to gardening and practical approach to for instance planting bushes and trees for transition from the nursery to the garden soil. It also debunks a number of commercial myths about fertilizing requirements
