We have a scrub oak that has been growing between a pine and an aspen, which has made the oak very lop-sided. The aspen is gone now. How much purning can we do to the oak to try and even it's growth?

The general rule of thumb with pruning is never more than 1/3 at any time. Pruning promotes growth. For this reason you don’t want to prune in the fall as the new growth could be more susceptible to frost damage. Save your pruning for the late dormant season (late February – March). At this time of year it is also easier to see the form of the trees.

- We recently bought a home in Salt Lake city. The parking strip has very hard soil and weeds mixed with grass. Should we till it under and start over or air-rate it, keep it watered and sprinkle some grass seed on it in the fall or spring? We planted a sycomore tree (Bloodgood London Plane) and I think we stressed it by overwatering. About 50% of the leaves look sun scorched, some very dry and other leaves are green, full and lush, will it snap out of it? Should I air-rate the ground with a pitch fork around it?
- What night-time temperatures are too cold for "tender plants" such as tomatoes, squashes, annual bedding plants, etc.?
- We want to plant a couple of trees in our front yard that don't get very big (about 10 to 15 feet high). Can you suggest any are not messy and don't send up runners? If you have literature on selecting trees, could you send me a link?
- We have a weed in our hay field that is choking out the field in quite a large area. The weed has a hard stem with heart shaped leaves about 1/4 to 1/2 inch in size around the stem leading to seed pods that look like flowers that are hard and have a seed in them. The seed is red and the husk around them is green when the seed leaves the husk is white, stem is hard green and stick like.
- 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?
- My petunias are horribly sticky - I assume thrips are in control although I have tried to keep them washed off (insecticidal soap) and sprayed with a systemic (orthonex). Is there anything else I might try? Would a dormant oil spray work, and if so when would I use it? Also, there are small worms that are probably chomping the blossoms. What would work to prevent or kill them? How do worms can get into my flower boxes, that are at least 6 feet off the ground?
- 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?
- My apple tree is starting to blossom. I love the apples but they always get wormy. When is the best time to spray them and with what?
