Well, it's my mother's garden and I am having a tough time trying to get her to understand the need for compost and mulch and unfortunately, she's in MI. and I'm in GA. But I'll remind her since she did ask what to do!
I, on the other hand have clay. We have been amending and each year I get one row (3x50) for root crops so I will add extra sand, vermiculite, compost and work it in good. I got some really nice carrots and parsnips this year so it must be working! Beets were a bust though
