Local Interest

Cedar apple rust is a fungal pathogen that gets its name from a life cycle infecting cedar trees, then plants in the Rose family and back again. This year, spring weather conditions promoted the development of cedar apple rust on ornamental pears, such as ‘Bradford’ and ‘Cleveland Select.’ As rust has developed, symptoms are more easily recognized with yellow-haloed orange spots on leaves and early leaf drop.  Tree owners’ questions center on “What is this and how do I treat it?”

 “Foraging” refers to the gathering of wild edibles for food to grace our table. Historically, the human race began as hunter-gatherers, gleaning food from what was found, not raised. With the growing interest in fresh and local, there has been a resurgence of interest in foraging for wild food.

Rhubarb, Rheum rhabarbarum, is an easy-to-grow perennial that lends a delightfully tart taste to pies, crisps and jams. The fact it is a perennial means there’s no extra labor to grow plants annually from seed like you do for the vegetable garden.  The edible part of rhubarb, the petiole (also called a stalk), is technically not a fruit, but its size relative to fruit trees makes rhubarb a nice fit for a smaller space.  The robust leaves, though poisonous, are eye-pleasing and make an unexpected addition into landscape plantings.

Galls are structures made up of plant tissue, forming in response to the saliva of mites or small insects as they feed. The number and variety of galls found on trees in our landscapes are closely associated with the weather and how conducive it is to gall-producing arthropod populations. Galls happen every year, it’s just some years the number may be higher because that insect population is higher. For the most part, gall formation on leaves is of little concern, while those affecting the twigs, branches and stems merit closer monitoring.

As mentioned in the previous garden update (Tree Galls-Part 1), galls that form on tree leaves rarely cause much in the way of tree stress. But there are also galls that form on other parts of trees. In most cases, gall formation on leaves and flowers are of little concern, while those affecting the twigs, branches and stems merit closer monitoring.
