infestation of black flies

Posted by betula_pondula (My Page) on

they are little black flies that are living in the soil and i think they are getting out of hand. I have my birch tree inside because i live in gilbert AZ and its starting to get really hot here. but ever since i brought the tree inside it has a big problem with these tiny flies. i read that you can let the soil dry out some and that might help but i dont want my tree to be in danger if drying the soil is an unsafe practice. birch trees are verry sensative and i dont want to screw anything up because i got this tree from the wild for yamadori and it is very important to me. please help

RE: infestation of black flies

Your tree is in danger - from being indoors. It will not survive long at all there and if your climate's too hot or dry for birch, then don't grow it, but keeping it indoors won't work either (and certainly allowing the soil to dry out won't!). Whatever the flies are, you don't want them inside either, and being outside will help them to move on (or else an insecticide might be needed - but don't assume the flies are necessarily bad for the tree itself).

I'll second what Lucy said.

Also, you might try removing the top layer of soil (or mulch, if there is any) from the pot, and replacing with fresh soil/medium. The flies are probably congregating for moisture or food or mating. As Lucy mentioned, the flies may not necessarily be bad for the tree. The presence of the flies could, however, indicate that conditions in the pot are not the best for the birch.

My guess is that the flies will move in a short while.

i took the tree outside and it gets pretty good sunlight now, the bugs are slowly going away so i think thats under controll now. My next question is how do i tell what kind of birch is it. i think its a silver birch but it looks like some type of weeping birch , if there is such a thing could you help?
