Is there anything I can do to prevent septoria on my tomatoes?

Septoria leaf spot is a fungal disease that appears on the lower leaves of the plant usually after fruit set. Characterized by dark spots surrounded by yellow haloes, eventually infected leaves turn brown and drop leaving the tomatoes vulnerable to sun scald. To control or prevent the spread of the disease mulch around plants creating a barrier that prevents spores from splashing onto the plant. If there are infected leaves, prune them off at the first sign and do not dispose of them in the compost pile. Avoid moving around the plants when foliage is wet. Keep plants adequately fertilized and water early in the day. Avoid wetting the leaves. A more aggressive strategy would be spraying a fungicide on a 7-10 day schedule.

Is it too late to put in a garden?

There are many plants and seeds that can go into the garden at this time of year. Select varieties that will mature in 50 to 75 days from planting. Check garden centers for transplants. Among crops that can go in at this time include carrots, beans, beets, chard, zucchini, peas, and brassicas like kale, brussels sprouts, cabbage, and kohlrabi. Salad greens, radishes and herbs do well into the fall.xxxxxxxxx My plants have stopped growing. The leaves and branches are wilted and turning yellow and brown.

A common garden problem during the summer is providing adequate and appropriate amounts of water. Over watering is easy to do if rainfall amounts are not considered. Most garden crops require one inch per week. If the problem persists you may need to improve drainage by adding sand or organic material. The other end of the spectrum is too little water with leaves appearing curled, burnt, crispy or brittle. Leaves can be yellow or brown in color and soil in the garden bed looks cracked. Consider adding mulch, a small irrigation system or shade cloth.

My tomatoes have developed light tan water-soaked lesions on the blossom end of the fruit. Some have turned black and leathery.

Blossom-end rot is not a disease, but, a physiologic condition. Fluctuating soil moisture supply during dry periods and low fruit calcium levels are the major causal factors. It is usually a calcium uptake problem, not inadequate soil calcium. Adequate and even moisture applied with deep watering, not frequent shallow watering along with proper mulching will help prevent blossom-end rot. Over cultivation damaging roots may also be a cause.
