Wanting to amend Waco clay!
My wife, daughter, and I just moved into a new house with a newly planted lawn of St. Agustine. I've taken up all of the flower beds, turned in a health amount of organic compost and am confident that I can keep a pretty good handle on the soil quality there. The lawn however...well, I didn't realize just how dense of a clay we've got until I planted a Magnolia tree the other day. My worry is this - if the clay is too dense, will my St. Agustine sod have trouble developing a healthy and deep root system? I've just begun a deep but infrequent watering program, but am curious to hear if there are any tried and true methods for improving the soil underneath (organically) without ripping up all the grass and tilling in expanded shale (with a baby on the way, the budget just doesn't exist for that sort of project). All feedback welcome and appreciated!
