Why are the lower leaves on my tomato plants turning yellow and then dying?

Most likely this is caused by one or two very common fungal diseases – Septoria Leaf Spot and Early Blight. These diseases are not usually fatal, but can reduce the yields and fruit quality of your plants. There are some cultural practices that will help prevent or minimize these diseases, including mulching, caging or staking, and watering with drip irrigation. The following publication gives detailed information on controlling these diseases. 

What can I do about spider mites in my garden?

Spider mites are probably the most difficult vegetable garden pest we deal with. Spider mites reproduce quickly during hot weather, so once you have identified them In your garden you will likely need to work to control them regularly until the weather cools down.

Options to Control Mites:

  • Spray the entire plant, especially the undersides of the leaves, with a hard stream of water. Repeat every 4-7 days until you do not see new damage or live mites.
  • Spray the entire plant, especially the undersides of the leaves, with neem oil, insecticidal soap (not dish soap!), or a horticultural oil. Repeat every 4-7 days until you do not see new damage or live mites.
  • Sevin, Permethrin, and most other common garden pesticides are not recommended because they do not kill the mites and will kill the beneficial insects that help control the spider mite populations.

When can I plant my vegetables for a fall garden? What vegetables can I plant?

Fall garden vegetables are planted starting in late July for broccoli, cauliflower, cabbage, beets, and carrots through mid-September for spinach, radishes, and lettuce. Almost any cool season vegetables can be planted for a fall harvest, although potatoes and peas do not typically do well here in the fall due to warm soil temperatures.
