And wasps, love them or hate them, are a number of the biggest tomato defenders. Fueling themselves with flower nectar, wasps feed their younger with a gentle food regimen of hornworms, armyworms, cabbageworms, grubs, weevils, leaf miners, and extra.
Marigolds are Helpful Entice Crops
Quite a few pests occur to like these flowers as effectively. Based on the USDA, pests drawn to marigold embrace aphids, earwigs, armyworms, cabbage loopers, leaf miners, spider mites, thrips, whiteflies, in addition to snails and slugs.

Tomato roots develop deeper into the bottom. They’ve a protracted main root that extends vertically to a depth of round 2 to three ft. From this root, many secondary roots department out laterally.
In the meantime, marigolds have fibrous roots. As a substitute of a single lengthy root, quite a few roots develop from the stem and fan out horizontally, nearer to the soil floor.
As a result of marigold’s roots are shallower and tomatoes are deeper, these crops aren’t instantly competing with one another for sources like water and vitamins.
Marigolds Beautify the Tomato Backyard
Since about 1950, there was an pointless divide between meals and decorative crops within the backyard. Fruits and veggies right here, flowers over there – and by no means the twain shall meet.
But, within the eons earlier than that, polyculture was how we farmed and gardened—not in single-crop monocultures, however by rising two or extra kinds of crops collectively in the identical place on the similar time.
