My failures ( also known as learning what NOT to do ) ...
Tried growing okra in soil blocks, I put them out in hot sun dried out and died.
Did battle with aphids on my cabbage, learned there was an ant nest in my soil was unable to identify so lost the cabbage.
Found raccoons invading my grow bags, so I lost soil and the time spent making the soil, and planting... ( think I may of found a solution )
Found aphids destroyed my taro, next year plan on doing war on ants that farm the aphids on my plants.
I guess some of this was my fault, not knowing how to work with God's insects / plants.
With my failures, I have also had break thru with heading toward my goal of growing more calories..
Had an electrician friend who used to say, "if you are not breaking anything, then you are not doing anything"...
I do find it good to make a journal of what went wrong, and fail differently next year, as why be insane and repeat the same mistakes? ;-)
