Edible Landscapes Can Reap Sweet Rewards
As you update your landscape this spring, consider using plants that are edible. There are many trees, shrubs, and herbaceous plants that have tasty and beautiful rewards. The term for this specialty gardening is edible landscaping and can be likened to the home landscape version of permaculture, which means permanent agriculture.

The photo below from Tammy Curley in the Bremer County Extension Office is a reminder that now is the time to look for the silvery-gray webs of the eastern tent caterpillar on apples, crabapples, wild plum, cherry and related trees.

Pine Wilt: Death and the Pine Tree
My pine is dying! What do I do?? This is a question throughout Iowa and the Midwest
Several things can kill a tree, notably, age, weather stress, (rarely) herbicide damage, and several plant diseases, but most often it is a combination of these that do the deed. For a few species of ornamental pine trees, though, there is a specific disease called pine wilt that can take out a large tree in a matter of weeks or months. The primary species affected is Scot’s pine; unfortunately it is one of the most commonly planted ornamental pine species in Iowa.
