Blossom end rot is a common disease of tomato plants, which is when the bottom of the plant wilts from a lack of calcium in the soil. Although blossom end rot can look detrimental, it is a pretty easy fix with a remedy of putting calcium back into the soil. This can be done by using a granule which takes about a tablespoon per plant, but you do not want it to touch the stalk. Liquid can also be used as well and mixed with water. Lack of being faithful to your fertilizer is important, for the more you are using it the more you are going to get a calcium deficiency.
Blight is a tomato disease related to the fungus family. Discoloration of the leaves is a beginning stage and happens from water splashing up from the soil onto the leaves. Unfortunately, this disease can take over your garden quickly and can destroy all of your tomato plants. To control this spread from happening, it is recommended to use 3 tablespoons of baking soda to 1 gallon of warm water, and a drop of dish soap. This helps your chemical to stick to your plant and to neutralize the pH that is unbalanced.
Pests such as hornworms and cutworms can invade your garden. Cutworms are known to attack the youngest phase of the tomato, whereas the hornworm lives to devour the top foliage on the more mature plants. Recommendations include treating with Dipel Dust or Diatomaceous Earth, since they are the easiest and most natural. These treatments can be sprinkled around the soil and plant, as well as on the plant foliage to help with the worms that are underneath. In addition to pests, aphids and whiteflies are also common in the garden to attack tomato plants. Tricat 70 or Neem Oil is recommended because it does a great job to suffocate.
