pruning for overwintering
I'm fairly new to gardening, and have been reading up about overwintering peppers. I plan to attempt this with my bell peppers and one hot pepper plant. I have a couple of questions:
1. I plan to take the route of drastic pruning to prep the plant for overwintering. Right now my plants have several peppers that are not ripe. Do I repot,bring inside, wait for them to ripen and then prune back? Or do I prune everything now,repot and bring inside?
2. I've chosen to use a mix of bark, perlite, pumice and quartz for my mix, as suggested on this forum. Unless I'm missing something, it seems like pumice is more of a west coast thing (I'm on the east coast). I don't think I'm going to have much luck locating it. What could I use instead?
3. Is quartz rock simply aquarium quartz rock? Or is there some special horticultural product I should be looking for?
I plan to work on this over the weekend, as our killing frosts will begin soon. The average first frost here is early October.
Any suggestions are greatly appreciated.
