Marigold can be very beneficial to your vegetable gardens for many reasons.
Not only do they attract important pollinators, but they also can deter pests like nematodes, mosquitos, and cabbage moths. They can be an effective trap plant as well, luring pests like slugs to the marigolds instead of the other crops in your vegetable garden.

Because of its insect repelling properties, marigold makes for a great companion plant for a variety of plants.
Marigold is great to plant with vegetables like tomatoes, cucumbers, carrots, squash, pumpkins, and jalapenos.
It also pairs well with herbs like basil, cilantro, lavender, chives, parsley, sage, and thyme.

Marigold is an annual, meaning it will only live for one year. Marigold does often self-seed, and may grow back again the next spring. With proper care and the right conditions, marigolds can live until the first frost of fall.

Marigolds can be easy to grow from seed because they are low maintenance.
Follow the instructions printed on the seed packets to help the marigolds sprout and continue growing. Deadheading old or dried flowers from the marigold plant will help keep your plant looking healthy and encourage fresh, new blooms.
