I have a large, old walnut tree in my front yard. The bark on the east/northeast side of the tree is separating from the trunk. Is this a sign of disease or other problems? And can I peel the bark off the tree or will that hurt the tree?

There has been some reports of Walnut Twig Beetle and canker diseases on walnut, however the bark peeling usually is on the south west side of the tree. Don't know without photos or other information what the cause of the peeling bark. Do not peel off the tree, more injury may occur and generally not recommended.

- I have a small backyard that has a house on the west and north side, a cinder block wall on the east side and a large tree shading a portion on the south side. Due to the high sides of our yard, we tried some part shade/part sun plants last year. But they got blasted in the heat. Our yard doesn't get 10 hours of sunlight but it gets very hot. Can I sucessfully grow a vegetable garden in part of it up against the houses and plant something along the cinder block wall - preferably grapes or raspberries, or other covering plants (can be non-fruit). Can you recommend a plant we can grow along the wall, both in the shaded and sunny parts? Any recomendations for better use of the space?

- 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.
- Last summer I made some strawberry jam which I water canned in pint jars according to the directions in the pectin box. It seemed that all the lids sealed (they all popped). Now, though, the jam doesn't look quite right to me--it's a bit brown, especially toward the top of the jars. I'm a little wary of eating or even trying it. What could have caused this? Should I throw it out?
