Well, I have a hideous fungus gnat infestation. I figure I need a plan for handling this, so I’ve typed one out below.
- Stop panicking.
- Prioritize plants to save(everything else is either already dead, or really sickly):
- Empty out and sterilize containers that currently hold dead/sickly plants.
- Continue using sticky traps.
- Apply DE to soil of banana and rosemary and perhaps also the strawberries if it’s not to hard.
- Apply BTi drench to plants I wish to save. (Basil and lettuce box 3 are self watering containers, so I’ll add the BTi to the water reservoir and keep my fingers crossed.
- Repeat steps 4-6 until the pests are gone. Repeat step 3 as needed.
- Make soilless mix and replant what needs replanting. Also transplant rosemary into a bigger container with soilless mix at this time.
Basil if possible
Lettuce box 3, if possible
Thyme, oregano, and sage if possible
It’s possible that using DE and BTi is overkill, but right now an aggressive plan of attack makes me feel better.
I’m definitely going with a soilless mix in the future. The gnats got in through contaminated potting soil. I just hope a soilless mix really will be pest free.
I’m trying to decide of I want to use coir (coco peat) instead of regular peat. There seem to be advantages and disadvantages to both, though i hear coir has fewer problems with fungi and fungus gnats. Either way, I need to find a good potting mix recipe. I’ll be adding some container gardening books to my library request list, and taking copious notes.
