Is there a product that prevents sprouts from coming up along my cherry tree roots? It seems to be a continual problem.
Undiluted Round Up will help kill the roots. You will need to wound the roots (normally, people cut the suckers down and use those wounds) and then paint the undiluted Round Up on the wounds. The bigger or more wounds you paint, the better. The roots will suck the Round Up in and it will kill them. You may have to repeat the process a few times to fully kill the roots if the root system is still strong.
It has been raining today and tonight it will be 27 degrees. How can I protect my budding trees from freezing? They are only 5 ft. tall.
I would recommend covering the plants with a bed sheet. This should be enough to keep the frost from settling on the buds. If you can, a few jugs of hot water placed under the sheets as well will also keep the air a bit warmer under there.

I live in the mountains, under pine trees at 3,200'. I have a 7 yr. old flowering cherry tree that has never been fertilized but blooms beautifully. However, last two years the leaves have come out before the blooms. Is the neighbor's oak tree that now shades my tree to blame? Can I do something to get it to bloom before the leaves appear? Thank you for any advice.
Flowering cherries do tolerate light shade, but if your neighbor's oak is causing increased shade, there's not much you can do short of offering to pay for part or all of a thinning for the oak. The traditional method of improving bloom is to add phosphorous, either with a fertilizer, or bone meal. You might want to try this. This article tells you more about fertilizing and other care: https://www.gardeningknowhow.com/ornamental/trees/weeping-cherry/weeping-cherry-growing-tips.htm Then again, maybe its a variety that wants to leaf out before flowering, and its just now getting to its more mature habit. As long as you're getting flowers, I think it's all good.
My cherry tree produced fruit but they are turning brown and shriveling. Any clues?
It sounds like brown rot. This article will help: https://www.gardeningknowhow.com/edible/fruits/peach/brown-rot-fungus.htm
I have a 26 year old fruiting cherry tree. I have kept it well pruned and manageable. The quantity of fruit has grown over the years and last year was a bumper crop. This year it blossomed well but now the leaves and fruit are covered in brown spots and many of the leaves are all brown. Around the base there is a lot of 'roots' coming out of the ground that are dry and crumbly - is it terminal?
This may be a disease called cherry leaf spot. This article has information: https://www.gardeningknowhow.com/edible/fruits/cherry/cherry-tree-diseases.htm
To get a diagnosis and treatment you can take some leaf and fruit samples to the Extension Service. This link will help you locate one: https://www.gardeningknowhow.com/extension-search/
I just moved into a house. The neighbor has a huge cherry tree with a lot of fruit. I have a cherry tree as well that is sort of growing sideways from the fence where the neighbor's tree is. I have a feeling it is a sucker that was let go and is now a tree. It looks healthy and there is fruit on it but the cherries are the size of peas. If this tree grew from a sucker, is that the result and can I cut it down without hurting the neighbor's tree?
Your neighbor probably has a grafted tree, and the little tree is most likely a root sucker that has come up. The root stock was used because it is very hardy and strong, but it doesn't produce good fruit. It won't cause any problems to cut it down.
5 year old tree. Healthy up till this year. Noticed a split in bark on main part of trunk 1 foot above ground. No blooms this year & very few leaves. Very nasty winter. Noticed similar trees in subdivision with same problem.
Your feeling about the severe winter are probably right. You may have a variety of cherry that's not as cold hardy as it could be. You might be able to repair damage, even at this date, as explained in this article: https://www.gardeningknowhow.com/plant-problems/environmental/tips-for-saving-cold-damaged-plants.htm
