I have a stand of Gambel Oaks in my yard, I would like to leave the oaks, but fill in about 12 inches deep to level the area out. Will this damage the oaks? Is there any recommended ground cover to place in the area?
Rate This FAQ
I do not recommend at all putting 12 inches of soil around the trees - any change in soil grade will essentially put the tree root collar a foot below soil and the bark will not do well. Many trees which have the soil grade raised around the trees eventually succumb to bark rot or other problems due to burying the tree - also the roots are also covered and water and oxygen is less available.
As for ground cover - it's heavy shade under gambel oaks so realize you need something that can tolerate shade. Generally I don't recommend ground cover close to trees - because of competition for water, nutrients, oxygen between plants and trees. Best management practices for trees is to lay a shallow (2") layer of organic mulch like bark nuggets around the tree out to the dripline/canopy of the trees for the trees to be healthy and happy.

- I planted a Chanticleer pear tree about two weeks ago (mid June) in Perry. I watered it everyday for about 5-6 days and have since cut back to 1-2 times per week. Many of the leaves are very dry and crumble when squeezed. Have I been over watering or under watering my tree? How often should I water it or is it already too late for my tree?
- My husband plants tomato and peppers etc each year. He plants directly under the eves of the house and the water runs off the roof with each rain storm or in the spring run off. I believe this is not good for the soil he is planting the garden in since we have an asphalt roof and I can see the debris from the roof on the soil. He says not a problem, I still have a hard time eating them without thinking I am getting some sort of poison in our systems. Suggestions?
- We would like to remove the lawn from a large area around some 40-50 ft pine trees and cover the area with decorative bark. The roots are close enough to the surface in some areas that using a sod cutter would damage the trees. Would it work to just spray the grass with a killer, such as Roundup, and then put the bark directly on the dead grass? Would this affect the trees in the areas of the partially exposed roots? Any other suggestions?
- Many of my potatoes this year have splits in them, but then the skins have grown over the splits, leaving a very uneven skin. Is there something I have done wrong? We have watered about every 4-5 days.
- The leaves on my grape plants have turned yellow. The veins are still green but the rest of the leaf is yellow. I added some iron about a week ago and have not noticed any change as yet. Is there something else I need to do?
- I have some problems with native Juniper trees dying(25 ft average height). They start turning yellow (chlorosis has been ruled out) then brown on south side first, then slowly spread to north end of plant. I have cut down one and found no signs of insect damage or disease. Only trees located next to a dirt road(South of trees) are currently affected. They started changing in color last summer. The county does spray for russian thistle on road. Yet no other trees seem to be affected. Can you provide other possible reasons or someone that may be able to come and see them (test them)?
- I just recently moved into a home that has these terrible "soda straw" type weeds that I can't get rid of. They pop apart and look like tall drinking straws. I have sprayed them with multiple rounds of poison (extra strength!) and dug them out by hand 2 or three times. They are coming back stronger than ever. What should I do?
- Flowering Pear trees. I have some mature "Chanticleer" flowering pears. For the last 2 years, the new foliage has emerged with curled leaves and a white, cottony substance. This condition seems to lessen with the hot weather, but the foliage doesn't seem to totally look healthy like when the trees were younger. What is it and can it be treated?
