Not sure how many of you have seen the thread I have in the Southwest forum and I have two types of bales I'm using. Straw and alfalfa.
After doing this project for several months now and seeing the difference between how the plants are responding I will not use alfalfa for this method of growing again.
Here's from my latest on the bales and a link to it. http://davesgarden.com/community/forums/t/766827/
Latest update. No pictures.
The cauliflower in the hay bales are getting huge. In all the years I've grown it I have never had plants with as big of leaves as these plants have.
Broccoli is doing ok.
The lettuce is going gangbusters and I need to harvest some of it before it bolts.
The spinach is limping along. Not doing as well as the lettuce.
Added some broussel sprouts.
Cabbage is still about half the size as those in the ground.
I really think this has to do with them being in the alfalfa bales instead of the hay bales.
I placed some red cabbage in the hay bales to see how they do compared to the green cabbage in the alfalfa and the one green cabbage in the ground. I also placed several of the reds in the ground for comparison.
I also have one broccoli and cabbage in the alfalfa bales and they are maybe a quarter the size of those in the hay.
So from what I have seen to date I would not use alfalfa bales again. Although the soil under and around the alfalfa bales is the deepest chocolate color. I have a purple leaf plum close to one of the alfalfa bales and it must really like the good stuff from the alfafla bales because it is still trying to push growth while all the rest of my fruit trees are losing leaves.
Now theres a thought. Wonder how all my fruit trees would do if I placed a bale of alfalfa near them and let them decompose? hmmmmmmm. I'm doing it.
