Title: Pest identification?
Post by: GingerPunk2 on August 11, 2017, 05:59 AM
Hey all.

So I recently bought a beautiful Chinese Elm from a local garden center. But since having it for a couple of weeks I think that it may have had some pest issues and this seems to be affecting my little larch pseudolarox amabilis.

Now I have realised that I was not keeping my trees in the ideal conditions. I.e a noob mistake of overwatering. This mixed with humidity trays has caused these issues to grow. I have since (last 3/4 weeks) become extremely diligent with watering only when the soil appears dry on the top etc. Leaving watering a day or two after thinking I should water them to be safe and to dry out the soil and reduce pests.

I'm pretty sure my elm has fungus gnats. As when I watered on Sunday a bunch of flies flew up from the soil. This was 2 weeks after noticing little almost see through mite type bugs in the soil. And a couple of little worms.

Anyway. I am in the process of trying to rid them by drying the plant out more and using fly traps.

I noticed the same little mite things in my larch soil last time I watered. And so did the same. Let it dry a tad more than I was comfortable with. As the soil has significant moss growth on it.

I watered it yesterday and noticed a weird colored notch on the trunk. So I pulled back a lose piece of bark and revealed a white silky like web patch. Picture attached. I have removed this from the tree but am having a tough time working out wether thus could be spider mites, a regular spider sack or some other fungal type infection.

Any advice and help greatly appreciated. I love my little collection and do not want them to die. I want to repot them all as I belive the soil is completely wrong. But have been advised against this at the current time of year.

Help me bonsai people you're my only hope.

Could you take a picture in the daytime?  That picture is blown-out so I can't really see what's being photographed.

Also, if its spider mites, blast it with the hose.  Its surprisingly effective.

The plant in the picture is not Chinese Elm.
