2. Infected Tomato Plants

Asked by Anonymous - November 15, 2010

I planted two tomato plants in my vegetable garden about 2 months ago. They have been doing really well until recently when the bottom stem and leaves began turning yellow and a white substance is now evident on the dying parts. Is this a fungal disease or pests?

  • It does sound like a disease. It is likely a blight (there are several) as these tend to move from the bottom of the plant upwards.


    There is not much you can do for the plant. While the fruit is safe to eat, it is recommended that you remove the infected plants and destroy them to prevent the disease from spreading. You will not be able to plant tomatoes or other nightshade plants there for at least 1 year, as the disease will survive in the soil that long and infect any nightshade plant that is grown there.

3. Yellow Tomato Leaves

Asked by Anonymous - November 20, 2010

I started a raised garden in south FL, and amongst many veggies I have 3 tomato plants in pots. One plant has about 6 tomatoes but started getting yellow leaves up from the bottom of the plant. On one or two stalks, even the small new leaves are popping out yellow. No pests are present. What are your thoughts?

5. How Much to Water Tomatoes — in Gallons Per Hour

Asked by DarrellC - December 6, 2010

doin drip irrigation. what size, space, and flow rate should be used for Tomatoes?

  • There is no set answer for this as drip systems vary and there are many factors that can go into this.

    But, I can tell you tomatoes need about 2-4″ per week of water, including rain water and that it is better to water 1-2 times a week rather than every day and a slower flow is better than a faster flow.

    To figure out what is best for your system, place one of the drips into a container and let it run until the container is two inches full. If the container is 10 inches square and it takes 10 minutes to fill to 2 inches, you know that you need 1 minute per square inch watered for 2 inches. For each tomato plant, you want to allow for about 144 square inches of space to water, so in this scenario you would need to water for a total of 144 minutes per week.

  • I would also add that you should check the manufacturer’s website. They may have a drip irrigation calculator for their specific product that will help you figure out (without having to do the calculations) what setting are best for your system.

If I do not want my tomato plants to grow to a height of 4 feet (maximum), what can I do?

  • You should plant bush type tomatos that only grow to 2 or 3 ft. or you can prune the tops off when they reach the desired height.
