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.

- I want to plant raspberries in my garden next spring but am confused. Which does better in Cache Valley: summer- or fall-bearing? The USU pub on raspberry production (HG/2004-16) says plant only Haida or Malling Joy, but I haven't found anything about these species on the web. Is this statement still valid? If so, are they fall- or summer-bearing? If not, what is your species suggestion?
- I planted my tomatos around the middle of May and now they are big and great looking except not one of the 12 plants has a blossom on it. Am I not patient enough or what can I do about this?
- What trees, perrenials, shrubs etc... grow best in Utah (landscaping yard)?
- Can Blenheim apricots be grown in Cache Valley? If so, what problems might I expect?
- Do you have any suggestions as to where to buy or how to make a truly sturdy tomato cage? The "standard" metal ones I have bought at garden centers have always tipped over when the plant has gotten big.
- Something is eating my garden. HELP! At first I thought it was snails because there were quite a few holes in the leaves of my beans and squash. Now, there are just skeleton leaves left of half my garden. I have treated for snails with PAX and for other insects with Seven. I have looked for squash bugs but to no avail. I have seen a great many ants and earwigs. Oh, and my tomatoes seem fine. Any tips?
- I have much vinca minor (dwarf periwinkle) planted about 20 years ago as ground cover in my yard. Some is in full sun, some is in part sun/part shade. Some small areas of the vinca (3-4 feet in diameter) in several places in the yard have begun the most recent two Springs looking yellow/pale green, not deep green like the rest of the gardens. Neither have they flowered. A couple of the small yellow/pale green areas e thinned, and some of the plants died. The veins in the leaves of the unhealthy plants are green, but the leaves are yellow/pale green. They have remained thus all summer. They don't turn brown and dry and die. I have treated with fertilizer and snail bait, but neither has had any effect on the unhealthy looking plants. Are these plants deficient in some nutrient? Healthy plants I planted in the bare areas had a hard time establishing but did eventually and have not paled. What should I do? I don't want the problem to spread. The periwinkle has added a great texture to the yard.
- I have a peach tree with lots of little branches that look burnt at the ends. The rest of the tree looks healthy, but the ends of the branches keep turning black and dying.
