...particularly vulnerable to spider mites, powdery mealybugs, and nematodes
Not a problem.....just spritz the plant occasionally with water for the mites, as they like it dry.
And when I find mealy bugs, I add a little detergent to break down the surface tension,
and smother them. Also insecticidal soap should work.
If nematodes are the problem, nuke the soil in the microwave before planting, or use
a commercial mix.
Maybe someone else has experience & tips for these pests.
But worth it, imho.
