The mites or spiders are gone, and I cleaned the tree of its web. Is it just mites or certain spiders that will kill the tree and why?
I bought the tree from an indoor nursury, and havn't had it outside during extensive winter times. I was under the impression that anything under 20 degrees is to cold for the tree and will kill it. I was also told that allowing the tree to be outside for a few frosts is ok, but still shouldn't be subjected to drastic temparatures. I live in Milwaukee, WI, so we do get cold weather and plenty of icy snow until February. The tree was outside last night and is frozen solid now (as there was another ridiculious temperature drop). I did bring the tree in, as I was told it would be below 20 degrees, or around I should say.
I wont be pruning anything more during this time, just cleared its huge mass of needles to allow light and air to circulate. It was pretty congested though I miss seeing it full and messy. I am hoping to see an improvement of the needle strength after it makes amense with its new situation.
Also, how often should I fertilize and with what ratio. I usually have been using 20-20-20 and 7-8-9 (both diluted of coarse) in increments of 2 the stronger fertilizer and then 1 of the weaker stuff to avoid burning in spring in summer. The tree responds immensly. As we enter into the winter stages I have read mixed things about feeding. What would you suggest and also being in its current state the way it is.
I was looking at some fungicide/insecticide/miticide combo at steins the other day, and it said it could be used for shrubs, but I couldnt find anything specifically for trees, just other house plants and roses. Also since the mites and insects seise to exist (as it appears with no webs) I figured this might harm the plant after having pruned it. I could buy some and dilute it with water similar to the fertilizer? It said to use caution to not burn the tree, but with all due respect to your last post about it supposed to help the tree. NOTHING SHOULD BURN A TREE. Obviously. Any suggestions?
