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.

From the symptoms you are describing it sounds like your Vinca has iron chlorosis. This is a problem that some ornamental plants have with accessing the iron in the soil because of our typically high pH levels. Treating for this condition can be challenging and often the best control method is to use plants that are iron efficient. Below I have included a link to a fact sheet about iron chlorosis that contains more information on the condition as well as treatment options and recommendations.

- Is there another alternative to getting rid of ferry ring in a lawn than by removing the soil?
- I live out on the western edge of South Jordan. The home I just bought has very sandy/rocky soil. The lawn is an inch to inch and one half depth. I have decided to add at least four inches of topsoil to my back yard this fall and re-seed. The front yard is still worth saving. I have three questions. What is the best Ph level for my soil in this area and what type of seed will work best in high sun location such as the one I live in and last should I consider some type of organic treatment to my front yard to strengthen it and promote growth?
- I put in my entire yard in Fruit Heights in late July. I noticed my maple trees are losing leaves, and showing signs of distress. I put sod up to the tree trunks, but I'm wondering if I should cut the sod back, and put mulch in so the tree roots can breath. Good idea? I cut back on the watering as well, which could have been a problem for drainage. Any help?

- I have successfully grown summer squash for many years, but this year the newer leaves on the plants (sunburst hybrid) are wilting and dying, despite (or because of?) the cool wet June weather we are experiencing. The more mature leaves seem to be okay. I cut one of the leaves off at its base and didn't see any evidence of insect infestation in the stem or on the leaf. The base of the plant also appears to be free of insect infestation. Do you know what might be causing the problem, can it be treated, or do I need to pull up the plants, and if so, can I put new plants in the same location (the rest of the garden space is already filled)?
- Whenever I go into the supermarket in the summer time I see people picking out watermelons and talking about bee stings as indicators of a good melon, but I thought bees only sting when threatened and that the sting contains a venom. Is there any correlation between the marks on watermelon and bees? Adam
