I have a red photina thats leaves, in part of the bush, seemed like they were burnt. Is it a disease that these bushes can get? If I cut it back all the way, will all of the bush come out of it or should I get rid of the bush? The photina next to it is just fine.

Photinias can get fire blight. This disease causes the leaves and/or twigs to look like they were burned. Drought or sun scorch can also cause burning on the leaves. If your shrub is against a heat absorbing brick or concrete wall, or a reflective surface, such as a white vinyl fence, the absorbed or reflected heat could cause burn damage.
There is an excellent article with photos of photinias with fire blight for you to compare with your shrub's symptoms. This article will also give suggestions to treat the disease. Go to Google and type in fire blight photinia (or the web site is:http://cahe.nmsu.edu/pubs/_a/a-230.html )

- How can I get rid of Bur Buttercup? We have tried poisons over the past few years with little result. This year we tried a pre-emergent with little to no results. What can we do do get rid of them?
- I want to limit growth of newly planted fruit trees and wonder if it would be possible to do that by making a large wooden box and planting each one in a box in the ground? Also if it would work to do that, do I need redwood? I have a stack of 4 x 12 x 16 douglas fir lumber which had been painted on one side and I wondered if I could use them to do this or will they create bug problems?
- The grass in certain areas of my lawn is not growing well. I've been told it may be due to the fact that they're adjacent to pine trees, and that fallen pine needles have caused locally acidic conditions. It is suggested that I apply Gypsum in these areas. Are the diagnoses and suggestions plausible ?
- When moving into our new home I removed two small quaking aspen trees. Even though the main trees are gone there are a good multiple dozen shoots that are coming up all over the lawn. How do I get rid of these for good...hopefully without ripping up my entire yard? Also my neighbors all have these aspen trees and I would like to "treat" the baby shoots coming up on my side of the fence line without damaging their trees. Is that possible?
- I've just moved here from Maryland and I'm starting to landscape our yard. I've noticed that none of my neighbors use mulch in their flower beds. Why is that? I thought mulch helped to keep the soil moist as well as keep out the weeds. Plus you can till it back into the soil in the fall for aeration.
- I have an older crab apple tree that is focal point of my small yard. About 3 years ago the leaves became infected with powdery mildew. I have been told to not do anything with this, as it will eventually go away and the tree will fine - but over the years it has gotten much worse each spring. There are only about 60% of the leaves that are starting to look healthy by mid-June. Over all, the leaves are withered and this year we have very few blossoms. Another problem: The tree also has four large limbs that come out of the trunk. I noticed that there seemed to be wood pulp inside a place where a branch was cut off years ago. I scooped out the pulp and found that some bug or other creature has created a cavity that goes 6” into the 10-12” diameter limb and a large man’s fist could easily fit into the hole that has been created. While inspecting the hole I discovered a ¼” or so hole in the very back of the cavity, but no sign of the culprit. The limb seems to be doing fine, as the leaves on the branches from this limb are in no better or worse shape than the rest of the tree. I had my tree pruned by a highly recommended person this spring, in hopes that this would help with my powdery mildew problem. I love my tree, what should I do next about my perpetual powdery mildew problem and the unknown culprit who is dinning on my tree limb?

- Two questions; I have an dwarf Honey Crisp apple tree that is about 5 years old. Last year it had a dozen apples. I didn't disturb the fruit spurs when I picked the fruit. This year there were no blossoms on the tree. I didn't prune it at all. What can I do to help it produce every year? Second question; I have peach borers in the main branches of my nectarine tree. The tree seems healthy other than the borers. What can I do about them at this point? Will it help to dig them out? Will it help to spray? Will they winter over to next year?
