I planted green beans a little over a month ago, and all was fine until 2 weeks ago, they started turning yellow and were losing their green color. Now, the leaves and stems are falling off and it's a disaster. I also have 2 more beans batches (yellow beans, which are doing the same thing, and another batch of green beans that seem to be doing fine).
I'm new to gardening so i don't know much, but here are the things i have done and maybe you can tell me where i went wrong.
-- I water them every evening after the sun goes down, i check the soil with my finger to see how wet the soil is, i'm not over watering them i'm sure of that. I planted them in 3 inches of soil, i can't grow vegetables around my area because it's all mostly clay so i had to use potting soil. I didn't fertilize it because the potting soil i used said it has 3 months time of fertilizer already in it. I also kinda sorta crowded them, maybe a little bit? You can see how close they are in picture number 2.
Anyway, here are some pictures to show you how it looks.. i know, it's kind of embarrassing to show these even considering i'm new to this and green beans are suppose to be one of the easiest vegetables to grow.. lol.
P.S. the only difference between the healthy batch of green beans and the unhealthy one is that in the healthy batch there is around 1 inch of extra soil depth.. could this be why? I used the same soil and did everything else the same though.
