How can I prevent tomato hornworms naturally?
To prevent tomato hornworms naturally, introduce beneficial insects like parasitic wasps, which lay eggs on hornworms, eventually killing them. Handpicking hornworms at dawn or dusk is also effective, as they are more visible during these times.
What is the best way to use neem oil on tomatoes?
Apply neem oil in the early morning or late evening to avoid harming beneficial insects. Mix according to label instructions and spray evenly on all plant surfaces, focusing on the undersides of leaves where pests often hide.
How do I use diatomaceous earth for pest control?
Sprinkle diatomaceous earth around the base of plants and on leaves. Reapply after rain or watering, as moisture reduces its effectiveness. It works by dehydrating and killing soft-bodied insects.
Can companion planting really deter pests from tomatoes?
Yes, companion planting is effective. Plants like marigolds release substances that repel nematodes and other pests. Basil can deter flies and mosquitoes, while nasturtiums attract aphids away from tomatoes.
What are some signs of a healthy tomato plant?
A healthy tomato plant has vibrant green leaves, strong stems, and numerous blossoms. Regular fruit production and minimal pest or disease signs also indicate good health.
