The problem with alfalfa pellets is that they create heat as the decompose. I'm not sure that would be a good thing at this time of year.
I've lived in Marietta, GA, and there the clay was bright red. The only way I could keep the soil from clumping into one huge clump was to add a lot of perlite to the planting bed in addition to the organic fertilizers. The perlite was still identifiable 3 yr later and doing it's job just fine. The plants really appreciated this approach.
Now that I live in Central FL, I have to enhance beds, divide and plant in the late fall. I don't know about TX--can they still do that at this time of year? The only thing I do know is that it gets really hot down there, and the roots might not have enough time to get settled before the heat gets intense. But then, I've never lived in TX. Perhaps that not a problem for them.
