So I planted a garden about 2 weeks ago. This is my first garden ever. I used 4 bags of topesoil and 4 bags of cow manure blended into a 10x20 plot. I planted beans, and they cam up but are starting to turn yellow. My zuccinis seem to have died but 2 managed to come up out of about 8 seed holes. I got tomato, tiny tim tomato and cucumber and squash transplants. The cucumbers are dying, 2 died, thier stalks are turning dry. My squash plant is starting to look pale yellow and getting a dry stalk too. The tomatoes have yellow starting on the outer fringes and the tiny tims are getting yellow around the lower leaves. My pumpkins came up ok without any trouble, so far. The garden gets full southern exposure from about 9am to 9:30 p.m. Whats wrong with my plants?? We do have slugs and they have chewed on a few but not seriously. The problem seems to be in the soil, thats my guess. I dont want to use slug poison because I dont want to poison my birds since I free range them a bit. We have ants too, but they dont seem to be in the garden that I ahve seen. Our soil here is pretty rocky, but ive done alot to soften it up. The dark clumps are some of the heavier bits of cow manure. This first picture is my squash and cucumber and the small bushy plants are my tiny tims. These are my bean plants I planted as seeds. They seem to have turned bright yellow.
