HD Miami Supreme
I have an HD Tree Miami Supreme Gardenia & live in MD 20 miles outside of DC. It had a wonderful summer outside in morning sun from 8 am till about 11. It was fed and cared for all summer into fall and brought inside to our south facing window in mid October. My beastly sheffelera gave it spider mites and Saturday i soaked each brach in a sudsy bowl of water & dish soap and tried to gently rub of netting infestations the next day I spayed it with water and soap then yesterday I sprayed Garden Safe houseplant & garden insect killer. Today I took it outside (it's about 55 degrees) and sprayed it with a garlic, lemon juice, cayenne, dish soap spray that I let marinate over night. It now sits in a huge pebble tray (lifted up by two plant tray inserts) my question is....do spider mites live in dirt? The plant gets watered twice a week when it dries out. I can't imagine they could survive but I put them right up there with roaches. We're forecasted to have nice weather this weekend and I'm planning on spraying it again. What spray should I use? I like the all natural approach rather than any more dish soap or commercial sprays. Will post pictures of past & present it has lost about 35% of its leaves.
