Just a hint of wilt at stem ends yesterday. Today the entire plant is more wiltly than not. Must be bacterial wilt. This experiment was to grow a late season plant on the balcony well away from any soil contamination. Potting mix was leafmold/compost blended with about equal parts of commercial potting soil. Wanted to see if the above ground planter location could avoid disease issues. The bacterial wilt must be in my compost!
