Some years back, we reported on what, at the time, seemed like one of the least intelligent and most misdirected tick "management" schemes we could imagine. We commented about reports of doctors advising patients to wear dog or cat flea collars around their ankles and necks to ward off ticks and thereby prevent Lyme disease. The recommendation a year later by a popular horticulture radio program to dust cut Christmas trees with flea and tick powder to control ticks matched the flea- collar-on-the-ankles routine for stupidity but was at least less likely to cause damaging human exposure.
Perennial flower gardeners really appreciate plants with an extended season of bloom. The perennial flower that immediately comes to my mind when thinking of long bloom is coreopsis. Coreopsis, also called tickseed, possess daisy-like flowers in various shades of yellow to dark gold to almost orange. A newcomer to the numerous coreopsis offerings is Coreopsis rosea, the only pink form. Flowering of many varieties begins in late spring and continues through most of the summer.
Ivy is susceptible to a number of fungal leaf spots. The spots are caused by a variety of fungal species. They cause round to irregular spots in a variety of colors. Often small black specks, which are fruiting structures of the fungus, can be seen in these spots.
To control leaf spot diseases, remove diseased leaves or stems. It is also a good idea to remove old leaves and debris from the beds each spring before new growth begins.
