Good luck with your citrus, it's really an outdoor, in the ground sort of tree, even dwarfs.

Gritty mix is more of a function of where you are and how you grow your plants. If you live somewhere cool and moist, I guess it would make sense. My climate prohibits the use of gritty mix except for orchids. If you don't need your mix to retain a lot of water, give it a try. You'll have to experiment with a new watering & fertilizing schedule.

Thanks all, Marianne I know citrus do best in ground but I have definitely seen some pretty freaking impressive container trees too on this site and I plan to have the same success! I'm a year in with 13 trees now and they are doing pretty good, I am getting fruit, slowly but surely.

It's hot and dry here in the summer, but nights are cool and my grow room probably keeps the root zone a bit cooler than ideal during winter even up off the floor so thats also why I was thinking of going gritty. I have a meyer that was my first tree that I abused pretty badly when I was still learning to I plan to use that as my tester tree just in case I kill it with the mix. Thanks for the info though, good to consider!

Back to the peppers- thanks chileman, I currently do most of the stuff on this list but there a few more things I can try. I am determined, I will triumph over the fungus gnat! Still I think a sandier mix would only help.

Citrus grows well in containers - there are many ppl here that grow them and you can find lots of info&photos on either Citrus forum or Container gardening or House plants forum.

You could consider 5.1.1 or gritty mix - they will work well, all you need to do is to get used to different watering. What kind of sand are you planning on using? - fine sand will not be very good as it compacts and impairs drainage and air exchange.

Best way to get rid of fungus gnats is to eliminate (as much as possible) conditions they like - moist, organic...
