I have a fungus gnat problem with my houseplants, I’ve kept them relatively under control using Mosquito Dunks in my watering can since August and some yellow sticky traps but I can’t seem to eradicate them. I was considering buying nematode pot poppers but I’ve never used them before so I was wondering if anyone had any tips for application. All my plants are still relatively small so I don’t have many large pots for any of them (most are between 4-10").
Any and all recommendations welcome, having pests is really taking all the joy out of having plants. I’m in Canada so a lot of pesticides aren’t available to me.
I agree, sand would be best to try first.
Clay watering is a little different, you’ll need to use two layer pots where the outside pot is water tight and the inside pot has holes. Clear pot inserts work best. Before watering you’ll have to check if the bottom is still wet and add water & food upto just below the roots. What you are aiming for is to add the exact amount of water the clay can obsorb.
