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.

- I have small white worms in my turnips and radishes. How do I deal with this problem?
- I planted a Chanticleer pear tree about two weeks ago (mid June) in Perry. I watered it everyday for about 5-6 days and have since cut back to 1-2 times per week. Many of the leaves are very dry and crumble when squeezed. Have I been over watering or under watering my tree? How often should I water it or is it already too late for my tree?
- Our home was built in 1998 and we are the second owners. The first owners landscaped the yard, but didn't consider that the trees, shrubs, etc. would grow. We have trees that were planted too close to the sidewalk and shrubs that were planted too close to the house. They are beautiful, but too close. We also have a large cottonwood tree in the backyard that provides good shade, but its root are now pushing above the ground. I think I know the answer, but is there a good way to redo the landscaping without removing all of the good features at once?

- I have just moved into this new house and I have all these raspberry bushes. They have produced a crop of fruit and I went out and picked lots of berries. The berries themselves look very nice but they are a little small. When I brought them in the house I noticed a couple different kind of pests on them. A black little beetle looking bug and a little tiny bug that resembled the hair on the raspberry. I washed them off, cleaned them and ate them. Now I am all panicked that I will get sick. They tasted good but I have myself all freaked out not knowing if all the bugs got off. Will they hurt me? I want to make raspberry jam with all the berries I have. Is that safe?
