Yep, I think it's a matter of heavy clay soil which normally did not present such a problem considering the droughts Texas has experienced for years but when it rained, it poured & problems that have been "lurking under the surface" made themselves known. I think the overall solution is to improve that clay into something more livable & she's taking strides to do that. Also, I think she was being stingy on the feeding thinking she might overfeed them. The alfalfa pellets will take care of that as well as helping that clay to boot. I told her to find some earthworms somewhere & dump them in the garden too.
