Russell,
I plant mine with the soil about 1-1 1/2 inches from the top of the pot.
This provides a little more humidity and I can flood the plants when I water
them which in turn controls the spider mites. You can also spray them with
water, but if/when an infestation turns really bad, Safers insecticidal soap
works very well. I use the concentration recommended for vegetables, but a
more dilute solution will work just as well. Or add a drop of liquid
dishwashing soap to a quart of water and spray with this. Use sparingly,
and wash out the soil with pure water.
Good luck,
