problematic new potato shoots

Several months ago I planted several Swedish potato's (peanut?), they grew tall, strong and are now flowering, but the problem is that all around inside the grow boxes are new shoots, which are popping up in great number, even to the periphery of the grow box. Because of their great number and how far spread they are I am assuming they are not latent sprouts from the original seed potato's, but are (unfortunately) new shoots from the newly produced potato's, intended for our consumption and not for new plant production. What do you think is the source of these new shoots? Is there some scenario I've not imagined? This has not happened with the red potato's I'm growing.

Rose Blossom drop?

It appears as though someone snuck into my backyard and snipped off my Rosebloom's. Of course no one actually did. Upon further examination, I found that when I gently pressed against one of the blossoms on the plants that it easily broke away from the plant at the node. I didn't notice anything strange about the plant stems. The plant looks healthy in every other way. With the exception to the stem just above the mood. The stems adjacent to the decapitated flowers look okay for the most part. Some of them were very slightly chlorotic and a few others had a brown band like a fungus. But the Brown band was in the minority, i'm not even sure if it's worth mentioning. That's all I have to go on though. You have any ideas? I'm not near the plant now, but I could upload pictures at another time.

I have a juniper that I believe is damaged from the cold winter we had. I've waited to see it would grow more green, but it hasn't grown any new green needles. It's mostly brown, and looking into the branches toward the trunk, it looks dark brown, like it's rotten or dead. I'm wondering if I should just get rid of it, or if it might improve? Thank you for any insights.

I have a 20 year old split leaf / lace leaf red maple that suddenly seems to be dying. In early spring it's leaves opened up beautifully. About 1 month ago, I noticed the leaves were shriveling up and dying. Slowly the tree has lost it's fullness and the leaves are dying off. I noticed there is a white color on the leaves that are still alive, maybe a fungus? About 3 years ago, a heavy snow broke the main stem and some of the large branches. We took twist ties and pulled the branches together. To our surprise, the tree survived and the branches grew back together. Could it be diseased from that event? Is there anything we can do? It's in full sun and I don't use chemicals. I don't see any bugs. How can I upload more than 1 picture?

what should soil be tested for?

Would an arborist be helpful to determine the cause of their death?

What is the Problem with our Flowering Crab Apple Tree

We have noticed a white powdery accumulation on our flowering crab apple tree (Malus 'Indian Magic'). The tree was planted as part of a complete landscaping two years ago. It is approximately 8' tall and has vigorous growth this growing season. The white powdery accumulation is around year-old wood, not on new growth (a photo is attached). It does not seem to be on leaves. We talked to a local extension volunteer who thought it was "powdery mildew," but looking on-line that appears to be on leaves, and our problem is not on the leaves. We would appreciate any guidance. Thanks.

We have a black gum (Nyssa silvatica) that the county planted on our tree lawn last fall or winter (2013/2014). It has been doing fine until this weekend (weekend of 7/4-7/6) when the leaves started turning, yellow, then brown then drying up completely - all within the span of about 48 hours. We've been watering it regularly (when we've had less than an inch of rain per week) and don't know what has happened. Should we continue to water it and pray for the best or is all hope lost? We see no signs of tent worms or other external parasites...

Juniper tree blight?

I live in Crook County on Twin Lakes Ranch. We have many Juniper trees on our property and in the last 2 yrs or so I have noticed that almost all of them have brown dry tips that progress toward the trunk of the tree. At first it was only a few trees that looked like that. Now most all have brown needles through out the tree, some worse than others. It has killed several of our trees and I anticipate it will kill many more if not all of them. I have seen this in many other locations here in Crook and Deschutes County. Do you know what is causing this? Is there anything we can do to stop its spread. Thank you for your reply. I would be happy to attach a photo of what it looks like Randy McCauley - Powell Butte Oregon

Leaves falling off a Northern Red Oak.

Our Northern Red Oak started dropping clumps of leaves a few weeks ago. I thought maybe squirrels were eating something on the branch causing the end leaves to fall, but we haven't really seen any squirrels and the rate of falling clumps is increasing. Is there something we can do to save this tree? It's about 30 years old.
