Nurture Your Soil

You are feeding your plants, so why aren't they thriving? Many commercial fertilizers give your plants a short term boost. But these products do not feed the soil organisms that are necessary to keep plants healthy in the long run. In this interactive, entertaining and information-packed course, urban orchardist and fruit tree care educator Susan Poizner teaches you how to unlock your soil's full potential so that your plants and trees can flourish. This course includes:

  • 30+ video lessons (5-hours of video) and 15+ mini-quizzes to improve knowledge retention. (Value $250)

  • 4 beautifully designed, full-colour eBooks for course review and more detailed information. (Value $50)

  • 30-minutes of consulting with your teacher to ask questions and discuss soil strategies. (Value $75)

  • Membership to the community forum where you can share stories and ask questions. (Value $50)

Total Value = $425 USD. Sign up today for just $249 USD.


3 Reasons Why You Need This Course

You can buy the perfect plants and care for them properly - but without healthy soil those plants will not flourish. Here are three reasons why you need this course:

  • UNDERSTAND YOUR SOIL - You can see if a plant is healthy by just looking at it. But it is impossible to evaluate soil health at a glance. This course reveals how soil functions at a microscopic level. When you understand your soil, caring for it becomes intuitive.

  • SAVE MONEY & AVOID MISTAKES - Adding too much fertilizer can be expensive - and it can also irreversibly damage your soil and the environment. This course teaches you how to take the guesswork out of amending your soil.

  • REAP THE REWARDS - Whether you are growing fruit trees, vegetables or an ornamental garden, plant health starts from the soil up. This course shows you how to build better soil so that you can enjoy better harvests, healthy plants and a beautiful garden.
