One question we get so many times each year is: how much compost do I need? Also, what *actually* is a cubic yard, and how do I calculate cubic yards to gallons?! Worry not – we’re here – with calculators – to walk you through it!

Compost should be added to your soil at a ratio of 1 part compost to a minimum of 2 parts native soil.

• For lawns: Lawns can look great without chemicals. Aerate your lawns, then apply 1/4 – 1/2 inch of compost and gently rake into existing soil. Reseed and water as usual.
• For vegetable or flower gardens: Apply 1 – 3 inches of compost and rototill or mix into existing soil.
• For fall garden cover crop: Spread 1 – 3 inches of compost and seed cover crop in the fall to protect exposed soil. Incorporate the cover crop into the soil and proceed with gardening as usual.
