About

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. Create a beautiful and sustainable home garden guided by the newest information from applied plant physiology, biology, soils science, climatology, hydrology, chemistry, and ecology.

1. Garden Science: Weeding Out the Myths

25m

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.

2. Site Analysis: Choosing the Right Spot

27m

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.

3. Soil Analysis: What Makes Soil Great?

30m

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.

4. Living Soils: Bacteria and Fungi

29m

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?

5. Plant Selection: Natives versus Non-Natives

30m

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.

6. Plant Selection: Function and Form

35m

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.

7. Plant Selection: Finding Quality Specimens

28m

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."

8. Soil Preparation and Protection

24m

"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.

9. The Truth about Mulch

30m

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.

10. Planting for Survival

37m

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.
