Hello all, I have a small question to burden you with. Which pest or disease do you hate the most?
Mine would be the red spider.mite as they are immune to many pesticides and can do considerable damage. I would be interested to hear which enemy is your worst.

None. They are all similar and have their individual treatment and for most you can take precautions.

There must be one that is more costly or more of a pain more lethal.

And when you said that all them are similar then there may be a disease that has mutated as you wrote.

Here are two for you in one photo. Mealy bugs and scale. The tree, Fukien Tea, was a Christmas present from my son and wife. It arrived from Amazon with Brussel's name on it. TOTALLY infested. The tree was saved, barely, and is starting to resemble a tree again, but I have had numerous attacks of mealy bugs over the years on various house plants. They are big time killers if not stopped in their tracks.

Thank you for your post

luckily I have not come across mealy bugs.

can anyone tell me what is wrong with my bonsai juniper tree? I'm new to this. I have had the tree for 5 months. Initially I wasn't watering enough. leaves looked dry and gray. today i noticed which bubbly things on the branches. when i tried to scrape them off, noticed they were jelly like inside. Pests? Fungus. tree looks very stressed. I need assistance.
Thanks.

KK15647, please post this in a separate thread instead of hijacking someone elses subject.

Also, if you post pictures, especially of an unhealthy tree, do so with pictures of good color balance. The image you post is hard to assess, due to a blue-hue in the image.
