Now that you’ve done your soil tests, how do you turn your high pH clay soil into something you can really grow in?
You supplement your clay soil using soil amendments. What is a soil amendment? Soil amendments are products which help add organic material to the soil.
Adding organic material helps improve the structure of the soil, which allows better, stronger root development. Stronger root systems mean healthier plants and better yields in your vegetable garden.
Adding organic material also helps lower the soil ph. Soil pH is a measure of how “sweet” or “sour” our soils are. For most of us, our garden soils are alkaline (sweet) with high levels of ph. Our plants do better in neutral or more acidic soils, because they can better use the fertilizers and nutrients better when the pH is right.
When it comes to choosing soil amendments, it’s important to use Colorado-based products that are specifically designed to work in our clay-based soils. That’s why we recommend and sell locally produced soil amendments and fertilizers from The Richlawn Company Organix Supply. For over forty years, The Richlawn Company has been crafting garden and lawn products specifically designed to work in our clay-heavy soils.
Bagged soil amendments are convenient and consistent. The products within the bag are 100% organic and produced locally.
Our bagged Sheep, Peat and Compost contain aged sheep manure, peat moss and compost. Cow Manure is aged and screened dairy manure.
Natures Yield Organic Compost is EKO compost and sphagnum peat.
How many bags do you need? A bag of Sheep, peat and compost will cover 10 square feet, 2” deep. Add up the square footage of your garden or raised beds, then calculate the number of bags you’ll need. A 100 square foot garden needs ten bags of compost to add 2” of organic material.
Incorporating earthworm castings at this point will increase soil microbial activity and act as a mild fertilizer. A 30-pound bag will cover that same 100 square feet, 1" deep. Typically, you’ll want to add 1" to 2" of organic worm castings to your soil each season.
Take your bags home, open them up and put them in a pile. It’ll make it easier to mix all your ingredients together. So now we have this pile of amendments including a bag of Sheep, Peat and Compost, some coir, earthworm castings and we’re going to dig it all in about 50:50 with our native soil. You need your native clay to be part of the mix because clay tends to be nutrients rich in calcium, potassium and magnesium. Amended clay also holds moisture well and doesn’t compact.
Whether you’re dealing with an existing garden, a raised bed or starting a new vegetable garden, you should plan to amend your soil annually, spring and fall to keep it healthy.
