I’m in the last week of flowering in my greenhouse, and I have spider mites and mold on my plants bad. What remedies can I use naturally to fix it? — Dorothy Smith
There are no remedies to fix your infestation of pests and mold. You need to destroy your ruined plants and do some thorough cleaning of your space and self-reflection before you attempt to grow in your greenhouse again. The amount of webbing and powdery mildew on your plants indicates that you’ve had these problems for a long time and have seemingly done nothing about them.
Pests and molds must be discovered and immediately dealt with, in order to successfully harvest your plants. A program of Integrated Pest Management (IPM), using several different modes of defense and attack is the best way to prevent or control infestations. You must incorporate routine spraying with organic pesticides and fungicides, as well as the timely release of predatory insects and beneficial nematodes.
Only active participation will result in a happy harvest, so check on your plants early and often and act fast when necessary.
