scale? on Acer
I have noticed a substance on a few of my japanese maples--first occured last season and now just noticed again on a plant I pulled out of it's winter storage. Looks like a scaly substance on the bark, between leaf nodes. I have searched th internet looking for a picture that is similar, but so far have not been succesfull. The "scale" is whitish, grey...very small, but covers about 2 inches of the branch. Most of the items on the web having to do with japanese maples elude to cotton maple scale--which this does not look like. Wish that i had a digital camera to post a picture--so any help would be great. Thank you

Please provide a picture! Also, regular scales range from about 1mm to 6mm. Do you mean yours are 2 inches or that the area that these little things affected is 2 inches long?

as soon as I get my camera back I will post some pics. I am quite sure that it is scale.....but what kind stumps me. The infected area on this particular branch covered about 2 to 3 inches total--not one scale!
I have been looking on some of my other maples, the same ones that had scale from last season, and I am noticing much damage to the bark on the limbs and trunk. It looks like parts of the bark have turned grayish instead of the typical reddish. All of the plants have new buds, but a few have budded out much later. On some of the trees, there are a bunch of extremely small white looking "dots". Dots is probably a really bad descripter, but they are very small and irregular. I am not sure if scale is random, then begin to group as they grow, or if these small spots are something entirely different. |
