Massachusetts New England Hoya Collectors What Systemics and Miticides Are You Using?
Hey everyone!
I’m a Hoya collector in Massachusetts looking for recommendations on effective pest treatments that are legal to use here.
I currently use sulfur treatments twice a year for flat mites and broad mites, which has worked well for me. However, I’m looking for a strong liquid systemic insecticide (soil drench, NOT granules) to control mealybugs, root mealybugs, thrips, and other common houseplant pests.
I’m also interested in recommendations for an effective miticide as an alternative to sulfur when needed.
For context, my Hoyas are grown in self-watering pots with a chunky substrate consisting of tree fern fiber, large and small pumice, small fir bark, worm castings, perlite, zeolite, lava rocks, and small pond rocks. Tree fern fiber is the main moisture-retaining component of my mix.
With Massachusetts pesticide restrictions, I’m having trouble finding effective liquid systemics approved for indoor houseplants.
What specific liquid systemic insecticides and miticides are other Massachusetts or New England Hoya collectors successfully using?
I’d especially appreciate recommendations from collectors using self-watering pots and similar substrates.
Thanks in advance!
