growing marigolds around other plants..do they keep thrip,mites away?

Answer 1

French marigolds deter nematodes (worms)

Plant marigolds near asparagus to repel beetles

Tansy, marigolds and nasturtiums are also repellent to beetles.

Nasturtiums and marigolds planted near squash plants may deter squash bugs.

I would try using marigolds to prevent thrips and mites away from other plants

There is a variety of marigold that is almost daisy-like in appearance, with yellow-orange petals... the marigolds you would purchase would be the ones with the frilly petals

Answer 2

Theroy: Planting Marigolds attract the Hover Fly, THe hover fly eats aphid larva BUT Timing is WAY off, A tomato plant will be dead from aphids before the hover fly is mature enough to lay eggs

Theroy: Marigolds kill root knot nematodes, reality you need to plant on a 6x6 pattern of Marigolds, every other year and till them in to be effective

Answer 3

Marigolds keep a variety of bugs away. But they arent perfect. Keep an eye out for bugs that they dont affect.

Answer 4

they will repel a lot of bugs. after the first year you don't have to buy any more. save the seeds and dry them, i haven't bought marigold seeds for years and i have 3 gallon jars of the seeds.
