Tim's Tips: Watering can wash away fertilizer


Many people have come into the store with leaf samples from their tomato plants. The leaves are yellow, and they have some spotting. The customers are concerned that the tomato plants have late blight. At this point in time, the yellowing is probably from lack of fertilizer. The spotting is a fungus disease that is called leaf spot. As with all fungus diseases, the earlier you treat the disease, the less likely it will be to permanently damage the plant. There are some good organic sprays that you can apply to your vegetable plants to prevent and control certain fungus diseases. The key to effective control is to start early before the disease gets well-established on your plants.

Ants continue to be a problem both indoors and out. If you see large, black ants in your house, you probably have carpenter ants. These ants bring eggs into areas of wet wood, and those eggs hatch out into a larval stage that eats wood. They can do a lot of damage to your home. If you can find the source of where the ants are living, you may be able to control the problem. If you cannot find the source, you should call in an exterminator to treat for these ants.

Well, that’s all for this week. I’ll talk to you again next week.
