I planted some bush beans in some free space that I had and some came up mangled starter leaves. And it was all of one specific variety I planted. The others came up fine. For some reason, the Borlotti Beans were trashed when they broke the soil surface. One poor plant had no starter leave to speak of.
I did a bit of research and have concluded that it was not a bird problem, nor was it an insect. It must be one of two things: I planted them too deep or the soil was too moist. Or maybe both. Interesting that the other plants were not affected though. There are some Yellow Beans growing next to these and they had no problems.
I'm going to guess I planted these too deep. Only three came up and I'm certain I seeded more than that. But all is not lost. Despite the initial lack of leaves, the first true leaves are emerging and they look fine. Now they just have to survive the inevitable wave of aphids and spider mites.
