White stuff on white pine, adelgid?

3 years ago

I just got these young white pines. Here is a close up of it. This particular tree doesn't have much of it but the other tree I planted has all its candles covered with this stuff. What should I do?

Not sure, might be adelgids, insect-scales or maybe just spider-silk.

The white waxy strands visible in your shot look like those on pine bark adelgid:

really need that pic .. BEFORE YOU DO ANYTHING... first thing that crosses my mind.. is the possibility of you not recognizing a maturing bark ... how big a pot is a 4 foot pine in??? .. and what is the media??? there is a conifer forum.. but most of those peeps hang here.. so no need to move the post ... ken

it NORMAL ... it fungus breaking down the wood.. or compost in your soil ... or its perlite from the potting media you put in the ground.. i cant tell ... turn your soil over.. and mix it up ... and then plant ... any divergence of soil types.. or in your case.. potting media and soil.. is not the greatest.. so mix it all up ... ken ps: and a pill bug .. rolly polly ...

For future reference: I am now pretty sure these were indeed spider mites. I sprayed the plant heavily with a solution of 1 teaspoon dish soap in 1 liter of water, being especially thorough with the underside of the leaves. I did this twice, three days apart, and the problem seems to have been resolved. I never saw any mites on the plant. However, it spread to a couple of nearby plants, on those I could see small black specks underneath the leaves, which appeared to be spider mites. Luckily, it seems the spraying has been more successful then I could ever hope, and all the plants now look clean.

need a better pic of the eggs.. and a scale ... and if we cant ID it.. try the garden clinic forum ... there are some bug sperts over there ... keep in mind.. there are a lot more beneficial bugs.. than bad ... so dont go hyper on removal.. until you get the ID .... [are they already cut off.. and in a plastic bag?? .. lol] you have been holding it in a pot???? .. if so.. thats the yellow issue ... probably lack of nutrients ... how did you protect the pot for winter.. was it in sun.. so the black pot froze and thawed all winter????? ken

I have what I think are mealybugs on several of my white pines. Other than being mildly unsightly for brief periods, they don't appear to do any harm to the trees. Mine are mostly at needle bases though, not on candles.

I see them on my pines also. I've just ignored them but then they've never got bad and didn't seem to do any damage. You can just wipe the few off you see with your fingers.

The second summer I had my 'Niagara Falls' in the ground, the plant was covered with them. I used a Bayer soil soak product (the name of which escapes me), and I haven't seen any since.
