Gray Leaf Spot and Heirloom Tomatoes
by John Yazo
Growing a healthy and productive crop like tomatoes can be a challenge at time if diseases interfere with the growing season. There are many critical diseases that can hit your tomato crop. Gray leaf spot is one of these critical diseases which affects the leaves of tomato plants. It is a disease that can effect both seedling and mature plant leaves. This disease is started by infecting the oldest leaves on the plant first.
Symptoms that are noticed are small, dark spots that can be seen on both the top and bottom surfaces of the plants leaves. These spots will enlarge and turn a grayish brown color. Eventually the centers of these spots will crack and fall out. The surrounding leaf areas will turn yellow and the leaves will dry and drop from the plant. Fruit productivity is greatly effected by being reduced or even completely stopped.
Warm, moist conditions will worsen the gray leaf spot problems in your garden. Remove all affected plants and properly dispose of, along with all garden debris.
Crop rotation is a good practice to include in your gardening practices, along with having a good healthy organic garden soil structure will greatly benefit the crops you are growing. Having healthy, strong plants that grow vigorously will help them defend themselves from most of the common diseases that develop in your garden. Nature has it's on method of protecting the plants it grows naturally. Organic gardening is that same method of growing crops naturally and healthy.
