Edema of Geraniums


Several ivy geranium samples have arrived in the Plant Disease Clinic showing symptoms of edema. Early symptoms of edema include tiny blisters on the undersides of leaves. Petioles and stems may also be affected. These blister-like areas can enlarge and will turn tan or brown in color and appear corky. Affected leaves eventually yellow and drop.

Selecting and Planting Hedges


Hedges serve several functions in the home landscape. Hedges provide privacy, screen-off undesirable views, reduce winds, and trap snows. Hedges are commonly used to mark boundaries, direct pedestrian traffic, and as barriers. They also provide habitat for birds and other wildlife. Hedges can be deciduous or evergreen, sheared or unsheared (formal or natural), short or tall.

Perennial Phlox for the Home Garden


Selecting perennials for the home garden can be a bit intimidating. There are literally thousands of species and varieties available. Among those that deserve consideration are several species of Phlox. (The word phlox is Greek meaning flame and refers to their brightly colored flowers.)

Sidewalks and Trees


How many times have you gone for a walk and noticed sidewalks cracked or heaved out of place because of tree roots? Unfortunately this problem is all too common. Not only are the damaged sidewalks a potential accident for pedestrians, correcting the situation can be damaging to the tree. Prevention is the best possible way to avoid having to deal with problem tree root systems. When root problems develop, root pruning may be necessary. Root pruning, however, should not to be taken lightly.
