[IBC] Kingsville Repotting/Cherry Borers
Hi again everyone. I have 2 questions so rather then
put them in 2 seperate posts i thought id just put them in one. I live in NY, NY the weather here hasn't been above 65 or so for more then 1 day so far this spring. We have had an incredibly cold wet spring this year. Our average daytime temp for the past week would be about 58 degrees. Usually we are in the mid 70's this time of year. Most of my trees haven't gotten enough light due to the incredibly rainy season we have had so far. "we set a record here yesterday for rainfall in one day which hasn't been broken since 1819". And havn't seen the sun for about a week, "today we had half a day of sun". Anyway enough about the weather. I have a 15 year old japanese cherry tree. This spring i noticed round 1/8 of an inch holes in the trunk. Hundreds and hundreds of them. They are in a horizontal pattern going around the trunk. Then they go up about a half an inch to 2 inches and start again around the trunk in a horizontal pattern. Its very strange. The cherry tree didn't flower this year which has led me to worry about its health. It could be due to the spring we've had. I also noticed a number of the branches are suffering and have weak looking leaves on them. Some are due to fungus from all this wet weather and not enough sun others just look fragile and worn not eaten just not healthy. I was thinking it might be some kind of bark borer. Some people after i have explained what it looks like to them have mentioned woodpeckers. I thought id see what you all thought it might be, and how i could tell the difference between woodpecker holes and borer holes. The holes are almost perfectly circular which lead me to think of borers or some kind of boring worm. Second question. I had a busy spring and haven't finished all my repotting yet. I have a old kingsville which i got early last year as stock. Not yet trained. I was going to train and repot this year but since its late in the season im not sure if i should do either this year. The soil is not what i would like it to be its to dense IMO and im worried about root rot. The root ball is pretty tight the pot is about 6 inches deep i was hoping to take at least 1 inch off it in the repotting. Due to my abnormally cold wet spring would it be ok to repot this late? I have noticed new growth starting to come out but it has definitely not yet matured. Thanks again Ben Griffin __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster.

[IBC] Kingsville Repotting/Cherry Borers
Hi Ben,
I have a 15 year old japanese cherry tree. This spring i noticed round 1/8 of an inch holes in the trunk. Hundreds and hundreds of them. They are in a horizontal pattern going around the trunk. Then they go up about a half an inch to 2 inches and start again around the trunk in a horizontal pattern .... Some people after i have explained what it looks like to them have mentioned woodpeckers. Some people are right Borers make round holes, yes, and many like cherry trees, but they don't emerge in neat horizontal rows. One species of woodpecker does this: the yellow-bellied sapsucker (sounds like an obscure insult, doesn't it?). For pictures of the bird and the damage, see: http://animaldiversity.ummz.umich.ed...icus/s._varius$media.html I'm assuming this is an in-ground tree... repeated "drilling' by sapsuckers can weaken the tree and lead to secondary infections. Putting burlap or wire screen around the damaged area is supposed to stop the bird from returning for seconds, but the damage may already be done. A vigorous tree won't be especially bothered by one spring's sapsucker visits. Second question. I had a busy spring and haven't finished all my repotting yet. I have a old kingsville which i got early last year as stock. Go right ahead, if the tree is vigorous otherwise. Box don't mind considerable root reduction, I'd certainly take off 1/3 the depth from a nursery pot. Cut into the outside edge, pulling out some of the old roots from the perimeter. Repot shallower and wider, like a somewhat oversized bonsai pot, or a bulb-pan. If we ever see the sun again :/ you'll want to keep it in partial shade; as long as it stays overcast and foggy, leave it out. Be sure not to overwater. It'll do fine.

I have noticed new growth starting to come out but it has definitely not yet matured. If you carefully washed off the soil from the roots, then repotted in bonsai soil, using a chopstick to ensure that soil goes everywhere between the roots, but took off very little healthy root, you probably will be OK. Remove any rotted root, of course. And cutting at the top won't hurt the tree. Jim Lewis - - Tallahassee, FL - Our life is frittered away by detail . . . . Simplify!

They do resemble the holes in that picture. However
the actual holes are move evenly spaced apart. They almost look man made but they arn't. Yes it is an in the ground tree its about 80 feet tall. With about a 1 and a half foot wide trunk. The holes do not make rows and then stop though like in the picture. They are neatly spaced holes spanning the width around the tree trunk in a neat line. I will take some pictures the next day its not raining which isn't tomorrow. And i'll post them on the gallery and attach a link in a post. Thanks for the kingsville advice. Yes it is in a nursery container but has been raised by a bonsai nursery so it is a shallow container. 8 inches wide by 6 inches deep. Just a cheap plastic container. I bought a mica drum to move it into which is 4.25 inches deep by about 18 inches wide. I'm hoping root work has been done a few times in its life so i will be able to spread them nicely over the wider pot. Ben __________________________________ Do you Yahoo!? Yahoo!

I will take some pictures the next day its not raining which isn't tomorrow. No need. They're yellow-bellied sapsucker marks. NOTHING else makes a straight line of small holes. They can "circumnavigate" the tree, make squares with dots, or any other combo. They seldom do any real damage, though I suppose, as an earlier responder said, they _could_ become an avenue for an infection. I've not heard of this happening, though, and think it is unlikely. I have a dozen willow oaks in my pasture that have been "punctuated" by these little fellows over the past 30 years or so and they're as healthy as a tree can be.
