I have a small backyard that backs up to a wooded area. The wooded area does not provide shade in the afternoon, as the lowest branches of the mature trees are probably 40 feet in the air. I would like to plant a flowering tree near the wooded area between two oak trees. These trees are 15-20 feet apart. Can I plant any flowering tree near these oaks without damaging the oaks or wasting my money on the flowering tree?
I would consider flowering dogwood, as these trees are naturally found within the understory of other trees. There are many varieties and most are hardy in Zones 4-9. The red twig is especially nice, iffering additional winter interest to the landscape.

I have an oak tree that is producing sucker trees all over the lawn surrounding the tree. They are not coming up at the base of the tree but from the roots. I believe that the reason is because the lower large branches and their smaller branches that are coming off of them are covered with spanish moss, which has killed them. The only part of the tree that is healthy is the top branches. How do I remove and stop the sucker trees from growing without killing the entire tree. If I have to cut it down, how do I kill the root system, which seems to cover my whole lawn and even under my fence to the backyard.
Actually, the acorns that fall from oak trees (as well as those "planted" by squirrels) will cause tree sprouts to pop up throughout the lawn. This article should be of some help in dealing with them: https://www.gardeningknowhow.com/ornamental/trees/tgen/weed-trees.htm
I've cut and cut hundreds of them but they keep coming back. I heard, the more you kill the root suckers, it tells the tree to make more. This tree is my only tree in the front yard. I did see something called "Sucker Stopper". . . . but I haven't tried it. It's $28/spray bottle.
Do you know of something I can plant to keep these root suckers from emerging to the top? One neighbor planted "Widela". Supposedly, it is fast growing with runners and blooms a yellow flower.
Trees tend to sucker when they are under stress. Lack of water is the most common reason for this, but there can be others. Some trees, like grafted trees, are always under a little stress and will always put out some suckers. You can reduce the number of suckers a tree puts out be removing stress from the tree. Make sure it is well watered and fed and that there are no pests affecting the tree.
We have a large woodland oak next to our garden and the sap is covering everything. How long will this sticky mess go on for?
If you are still seeing "sap", then it is not sap. It is honeydew and the tree has a pest infestation (likely aphids). It needs to be treated with a pesticide, preferably a systemic one like neem oil. That should clear up the situation.
I have a Shumard Red Oak that has been in my yard for 17 years. It has been struggling over the last couple of years. When it comes back in the spring, 1/2 the tree has very green leaves and looks great, the other 1/2 has very pale leaves. This year, the leaves on the pale half have brown edges and the leaves on the whole tree are pale. What do I need to do? I don't want to lose this tree.
It is very hard to diagnose tree issues without examining the tree. So, I would recommend hiring a tree expert in your area to look at the tree.
That being said, I know that this is not always possible. It sounds like it is some kind of fungus affecting the tree, but there is also a possibility that it could be a pest. If you treat the tree with both a fungicide and a pesticide, you will treat about 75% of what may be affecting your tree.
Also make sure to practice good tree hygiene and remove and destroy any dead branches and fallen leaves from now through the end of the fall. Pests and fungus can hide on dead leaves and reinfect the tree the following year if they are left at the base of the tree.
I have a young oak tree that was planted one year ago. The first year it grew really great, but now the leaves are getting covered with brown spots and falling off. What is the possible problem, and what can I do to treat it?
its lacking water.....oak trees drink lots of water.as a young tree try a soaker house around ur tree.give it at least half to 1 in watering.a wk.....hot weather more water.
How to get rid of red spider mite in large oak tree that is killing it. It is a 30 year old tree, 2 1/2 ft in diameter at the base. It is on one side of tree, at the top, and killing branches on that side. It is the side that is in the sun.
Nearly all insecticides have little effect on Spidermites. You have to buy a true Mitacide to get to them, check at your local garden center or nursery and see what they have available. Be sure to tell them it is to get rid or Mites. There are some systemics on the market that are very good at getting rid of pests. You put it around the base of the tree out by the drip line, working it into the soil well. Then water well. As it goes up through the root system and into the tree, it will kill what is feeding on the tree or causing problems. Spraying the tree and using a systemic may be in order if it is under heavy attack since the systemics can take a while to work.
