4-5 Year Old Japanese Weeping Red Maple Not Getting Leaves on Most Branches

Why did my 4-5 year old japanese weeping red maple suddenly this spring not get leaves on most of the branches. The tree is about 4 feet wide and about 4 feet tall. One small section of branches have healthy leaves right under the very top branches. The rest of the branches look reddish and healthy but only have a few tiny dried up leaves on them. We and our neighbors do not use pesticides. Nothing around the tree has changed that we are aware of - The tree gets about 6 hours of morning sun. I water when there is a hot dry spell. I have let water get on the trunk of the tree sometimes but I did not know that was a NO NO. The soil is good and we mulch and sometimes use miracle grow. Please help and let me know if you got the picture that I tried to attach. Thanks much!!

Re-potting a fig tree

I have a fig tree that is about 6 years old. I have it in a large container. I want to re-pot it but don't want to harm it. It is in full leaf and doing nicely. Last year I got 60 figs. Should I wait until fall to transplant it or can I do it safely now without losing my crop this summer?

Pinyon Pine Brown Out

My 14 year old pinyon pine looks really bad this spring. I have never watered this tree, as it is three feet from the neighbor's nice, green lawn. I have a native grass lawn that i don't water. It has had some minor pine tip moth die back in prior years.

This spring, all the inner needles have all browned, and even new needles are browning. there is no tip bending, like the pine tip moth. I see no webbing, like spider mites. There are tiny black spots all over the needle surface (not inside the needles). I see no larva, worms, beetles, in the tree. Could this be scale? What can I do to save it?

Mysterious Blue Bug

What is this bug? Found in my yard in Tiverton on Tuesday, May 14, but when I came back from getting my camera it was gone. On Wednesday, May 15 it was dead and in a small garden on the rough mulch. Perhaps came in on a southerly from some place tropical?

What killed our dogwood overnight

My son lives in Somerton Phila. and the trees there are the healthiest I have ever seen. I believe it was a dogwood or possibly a flowering white cherry and was healthy and lush. This year it was stone dead. Not one leaf? It had no signs of disease last year and we are worried about the other trees now. We are heartbroken. Thanks for any info. Wendy Kates, 609-206-4137

My Chinese Snowball bush is being divoured by tiny black bugs. The leaves and now the flowers are being eaten. This has appeared in the past few years. This year it is earlier and worse than ever. I have had this bush for approx. 20 years and it's been so beautiful. I am hoping I can save this. It has grown into a 10 foot tree. Is there anything that can be done to save it>?

Asian Pear Tree's Leaves and Blossoms have Turned Black

My five year old Asian Pear tree's leaves and blossoms have turned black. I showed a branch to my local nursery and they think it is " Fire Blight" but they are not sure. Last year it happened to one branch at the end of the season and it also appeared on an apple and quince tree. Damage was minimal. This year the Asian Pear is completely covered with black leaves but the the other trees are not infected at this time. Please advise me on what I have to do. Thanks

Tree roots and suckers in yard

Two problems. I do have a couple Aspens in the corner of my backyard plus the neighbor who’s Aspen got uprooted by winds has 10 more Aspens along our fence line. In addition all of the suckers coming up are in the grass and you stated not to get anything sprayed on the grass which would be impossible. Any other suggestions? Michael A. Martin

What is the Effect that Cicadas will have on Small Trees and Shrubs?

My question is about the effect that the cicadas will have on small trees and shrubs planted last year (skip laurels, plum tree, redbud tree, dwarf "crimson queen" Japanese maple and crape myrtle). I am not concerned as much about the branches that might be damaged this year but if the tree or shrub itself will be killed. So, my question is: will the cicadas kill my trees and shrubs that were planted last year or will the damage be to some branches this year but the plant itself will recover. If the cicadas have the potential to kill the plant itself, do you recommend netting. Thank you in advance for your assistance. Jill Lipton

Walnut Tree Pruning

Hello, When is the best time to prune Black Walnut trees? I read conflicting information online. I have 2 large trees that are multi-trunked, and I plan on reducing each to a single trunk. Aparently Walnuts are kind of a sappy tree and I've read of waiting until after leaves develop to prune to avoid excessive sap running. In the same paragraph I'll then read it's not an issuse..... so why should I wait? Tree pruning is typically done in the dormant/winter correct? It would be great if I could do the doing now, but I don't want to risk the health of the trees by doing something so major out of season, either.

Fruit trees - Denver

Hello, thank you for your advice. I am considering planting fruit trees in the south area of my West facing front yard in the city limits of Denver. I have been told that peach and plum trees, when pruned regularly, can remain 10' in height with 6' of diameter. I would like to know what trees you would recommend for my situation and what resources are available on the Extension website for planting/care suggestions.

Horseradish - Is the Flower Edible?

Hi again. I've had great success for the past couple of years growing horseradish in a Baltimore city recycling bin. (I encourage others to try.) I do nothing aside from harvest the roots in the fall, leaving a bit in for next year. This year, though, I'm getting a flower for the first time. Should I cut this before it goes to seed so it won't change the taste of the root? Or keep it? The bin has a couple of plants. Only one is flowering. I can't find any reliable info on the web about this. It the flower edible? It looks tasty, like a daikon radish flower. Thanks, as always.

Swarms of Small Flying Bugs - What are They?

We have had swarms of small (about 1/4" long) flying bugs (ants?) on the siding of the back of the house recently. An exterminator could not identify them. A picture is attached. Please let me know if they are damaging insects and if anything should be sprayed to control them. Thanks.

Seed Weevils

On your web page about Scotch broom You talk about using Seed Weevils as an alternative way of ridding us of Scotch Broom: this article was from 2009, it's now spring 2013. I want to know how is this working? What keeps these weevils from eating the seeds of other plants? We have an infestation going on of Scotch Broom this spring and I'd like to know what, if anything, is being doing by the state or county to kid us of Scotch broom without also killing the trillium, the salal, Solomon seals, etc. and there's the vine maples, too. The images I found of these weevils, grown, look a lot like those shield bugs we were being told about last season. What's the status of those bugs now?
