Holy cow Rick what do you do for a living?
Our last major flood in 1990 left 3 ft of sand over most of the yard. One section was pure mud, the clay side. I'm sure there is some silt mixed in.
I garden mostly on the sandy side which definitely has been amended amended amended. Before I did flower gardening I had a veggie garden. Root crops like potatoes and onions adored this soil. Other things were"ok." I couldn't figure out back then why my tomato plants were a pale green despite fertilizer. They needed lime. Acidic loving plants also thrive.
On my clay side I was going to plant tulips. I had read not to mix sand with clay, that it would set up like concrete.
I take it that's not true. Anyway I dug down 8 inches and amended with compost and planted the bulbs. They are putting on a great display right now.
I appreciate your excellent instructions. I needed you in '95 when I started gardening though!
