One key element to determining the success of your plants is using the right soil. It is important to understand that 90% of your plant's success is related to the soil. Soil is a living dynamic organism that is the foundation of life for your plants.

There are many components to maintaining the ideal garden soil for your plants.  Knowing what type of soil your plants need, what type of soil you have, how to amend and fertilize your soil and what options you have for organic pest control will ensure your plants flourish.  The experts at SummerWinds Nursery can help you navigate all of these choices.  They can help you select the best organic soil, choose between organic fertilizer and nitrogen fertilizer and offer many options for organic pesticides.
