[bobbygedd]

earlier this spring we put in a few hemlocks, they are all looking pretty bad, i thought it was from the drought, but im not sure. it seems the customer is watering, any input would be appreciated.

Wooly algid...(spelling)

I have hemlocks in my yard, One day I noticed what looked like little dustlike white pods on the boughs of the hemlock. I called a friend of mine in the tree business, and he looked at it.

I had them sprayed immediately, followed the program and haven't lost on yet.

You need to get them sprayed by a reputable tree company Like Alpine, Barlett etc.. First year three times, second year and on twice a year.

Yes you are so true ,the little cottony looking bugs sucks the leaves dry and then they fall off,or something like that,good website on the trees and on the bugs also,from what I have read spraying is only a temp fix,all the nursery's in the area stop selling them,I wish someone would come out with something as I have about 40 trees down from 50 app 5-8' tall that have adelgids in them

Oil spray in the winter, Malathion (sp?) spring and fall and woolly algeid wont be a problem.

Soil injection with Merit. Merit is systemic and provides season long control.
Good Luck,

Hello,

Hemlocks are risky business in NJ these days. I will not plant them unless the customer absolutely insists. If I do, then I do not give a guarantee.

If you are not near north jersey, head up to sussex county and go to sparta. There, complete parks have been wiped out by the wooly's. Spray works, but you have to keep on it, and quite frankly, I don't think its worth planting something that you have to try and keep alive. I would look for an alternative (though there are few to replace a hemlock).

Its a shame, but untill they can come up with a total cure, I'm staying away from them.

u think its that white stuff? isnt it kind of early for that? just put them in in march. they just seem really dry and discolored, if that is the problem, any idea what it would cost to spray them? say 5 trees, 6 ft tall?

You could do a soil drench using Merit insecticide for arround 10 bucks a tree. Merit is labled for Algid and will provide season long control, 1 app. pr year !

GREENS1,

Is there a liquid Merit or will granual around the base suffice ?

I recently sprayed with hort. oil for the wooly.

you can't get malathion anymore can you?

Merit comes in a wettable powder form. The granular form is for turf applications and would be cost prohibitive. Lesco sells it under their brand name. 2 oz jar containing 75% imidacloprid. Follow label regarding drenching or soil injection.
