Hosta Crown Rot


There have been several reports of hosta crown rot recently. Symptoms of the disease include marginal yellowing and browning of the leaves, beginning with the lower leaves. As the disease progresses, the leaves discolor entirely and wilt. In the final stages of the disease, most of the leaves completely collapse and lay flat on the ground. Because the bases of the petioles are rotted, the leaves can be easily pulled away from the crown of the plant.

Vegetable Harvest Guide


Harvesting vegetables at the right stage of maturity ensures the best taste and quality. Many vegetables should be picked throughout the summer to maintain plant productivity. The time, frequency, and method of harvesting vary depending on species. Vegetables, such as standard sweet corn, have a very small harvest period. Others, such as many of the root crops, can remain in the garden for several weeks with little effect on their taste. Some vegetables, like summer squash, have to be harvested almost daily. Other plants, such as tomatoes, can be harvested on a weekly basis.
