Believe it or not, it's time to think of fall gardens. Summer squash seedings should be wrapped up, potatoes seeded, and New Zealand spinach seeded. Some tomatoes are also experiencing some disease problems. The main ones are the leaf spot fungi such as Septoria. Protective sprays of a fungicide will slow the progression to the new leaves, just make sure to read the label on the product for the days to harvest restrictions. Also make sure your tomatoes are mulched as conditions are ideal for blossom end rot, caused by uneven moisture conditions.
