We have a large, flat fungus on our oak tree and would like to know if it should be removed.
You may have bracket fungus on your tree. Here is more information: https://www.gardeningknowhow.com/ornamental/fungus-lichen/tree-bracket-fungus.htm
I made raised beds and planted plants in them, but the oak trees about 30 feet away sent all its roots into the boxes and choked out my plants. Any suggestions?
Typically tree roots start to invade spaces like that when they lack water or nutrients. They are hoping to find these resources in the new space. Since these are new roots, it will not harm the tree to remove them. I would then try setting up a watering schedule for the tree away from the beds, such as a sprinkler that waters regularly on the opposite side of the tree from the bed. This will encourage the tree to start growing roots out that way as the resources are there to be found.
The leaves on my oak tree always seen to drop early. And not just a leaf at a time but the tip of branches. Right now the lawn is covered in them. I live in central Wisconsin area. Can you help me diagnose and fix the problem?
Stress is the number one cause for leaf drop. This article should help: https://www.gardeningknowhow.com/garden-how-to/info/plant-dropping-leaves.htm
My live oak is dropping millions of seeds and it never did this before. My son is a hunter and he says it's happening in the woods also, WHY?
It has been a stressful few years for trees due to the odd weather we have been having. Many trees, live oaks among them, will get a stress reaction where they will over produce seeds the year after a stressful year.
It is done as a precaution on the tree's part. It feels threatened and feels that it must try to reproduce to replace itself should it die, so it dramatically increases the number of seeds it produces to increase the chances of successful offspring.
I am trying to find out what type of plants and flowers will do well in both shade and sun. In the front of my house I have a large oak. It shades the bed to the right, but the bed on the left receives full sun. Any ideas?
Plenty of ideas, but tons of questions. Sizes of beds, how tall or short do you want the plants, shrubs, perennials, annuals, evergreen, deciduous, herbaceous, fragrant, blooming, color, maintenance free, how close are beds to a structure or sidewalk/drive, and what zone?
I planted a red oak tree about a month and a half ago. All was well until about a week ago, and now all its leaves are dried up and it looks bad. I suspect overwatering, but I'm not sure. I pulled all the mulch off and sure enough the tree could shift if you move it by force. I grabbed some mineral spikes and easily pushed them as far as I could around the tree, in hopes that it might help. Did I do the right thing, and is there something more I can do to try to save it?
How much and how often have you been watering? How large is the tree? How deep was the mulch? Does the location drain well?
When sending a tree or shrub home with someone, I always recommend the equivalent of 1" water weekly, about 5 gallons. This would suffice for almost any plant up to 8' tall with a spread of 4', and trunk diameter up to 1-1 1/2 inches. Larger plants should have 10 gallons weekly. Mulch should not be over 4'' deep, or the tree could smother.
We planted a Monterey Oak last year and it is doing well, except for recently some of the leaves are turning brown and rolling up. It gets plenty of water. We don't see any insects on the leaves.
