I'm about a week or two from harvest and battling caterpillars sprayed with BT to 3 days ago sprayed again yesterday this morning I noticed that my sugar leaves are turning black yesterday I had a bunch of white flies all over my plants paranoid some kind of mold might be setting in any thoughts
the black being dark purple stalled sap, being too cold to pump sap like all red plants, more cold, more red/purple/black, keep warm or some shelter yellow sticky cards work on white flies, caterpillars is a daily hunt or add some spray but caution you are close to harvest, another week or two good luck
