[IBC] 'Tis the season to be buggy
At least in the northern hemisphere, fall is on its way --
though with our 90+ degree temps it seems hard to imagine down here in the south. Too often, Fall means a sudden increase in nasty insects -- from chewing insects like caterpillars, and especially the sucking insects such as the various stink bugs (Hemiptera), lace bugs (Homoptera) aphids, white fly, and scale. Spider mites may be a problem on conifers. They're in a feeding frenzy as they get ready to lay eggs, hibernate, or whatever else they do to insure that their genes survive over the winter. A pyrethrin spray will take care of most of these beasties. The benefit of pyrethrin is that it is very lethal to insects, but short lived. If you prefer non-toxic sprays, horticultural oil will get (suffocate) many of them. A soap spray (repeated weekly for a while) will get others, and BT will get the caterpillars. A blast of water is probably enough for the spider mites. You really don't need anything stronger. Fall also means leaves are getting old. Black and brown spots on leaves -- especially on members of the Rose family (cherries, apricot, pear, hawthorn, etc.), on various maples, sweetgum, hophornbeam, quince, and many others -- are normal at this time of year. Sprays are NOT called for. If it really bothers you, remove the old leaf, but it's a bit late for complete defoliation so be careful. And note that even "evergreens" get old, spotted, and yellowed leaves (or needles) at this time of year. Ditto "tropicals." As fall advances, trees shut themselves down. They'll need less water, so overwatering gets to be a distinct possibility as some of your trees go dormant while others go merrily on their way. Keep your eyes open. You may want to rearrange your tables so the trees that need more water aren't sitting next to trees that need less at this time of year. A more thorough seasonal care article can be found in our website. Go to the "Knowledge Base."
