Soil Amendments

Amending your garden soil can significantly improve its health and promote thriving plants. The addition or organic matter and nutrients, in the form of well composed soil amendment, benefit nearly all newly planted plants by reducing compaction, retaining moisture, and feeding the newly emerging roots. Some plants need additional aeration, some prefer not to have added nutrients, while others prefer much more acidic soil than typical. We offer various soil amendment blends to appease nearly any plant we offer. Let us help you match the right amendment to your specific plant selections.
