Marigolds are a popular companion plant for veggies, particularly tomatoes. You can also place them alongside cabbage, broccoli, Brussels sprouts and other tasty favorites to help repel harmful pests!

Studies have shown that marigold plant roots create chemicals that kill root knot nematodes, as well as other harmful nematodes that feed on plant roots. If you are simply using marigolds for pest control and don’t care what variety you plant, go with French marigolds like our popular Sparky Mix. They have proven to be the most effective critter keeper-outers. At the end of the growing season, try working your marigolds into the soil to provide even better pest management. Not only will your veggies be protected, your garden will have the added benefit of looking full, colorful and cheerful.

Known for their aromatic blooms, marigolds are among the easiest and most versatile flowers to grow. They tolerate most soils and bloom brightly all summer long. They don’t even mind being planted in poor to average soil as long as it is not too soggy.

In springtime (any zone), sow seeds directly into your garden about 1 inch apart and not deep, just 1/16th of an inch. You’ll see sprouts within days and blooms in just 8 weeks! You’ll want to thin out the plants to be roughly 12 inches apart for best results. These beauties do like lots of sun but can do fine with a few hours of shade.
