Bin growen outside for a long time,started growen inside a few years ago,found a way to keep spider mites at bay.i mix clean white sand with diatomaceous earth and sprinkle on top of soil about a50/50 mix. I do this several times after watering in s.p. As the sand and earth work their way into the soil it fourms a barrier of sorts and won’t allow spider mites and other critters from digging in and laying eggs. Since I’m growing in smart pots this has little effect on air getting to roots and does allow water to filter thru ! I’ve found this very helpful and hope u will to.
