However, there are Marigolds that beautify your surroundings and protect your flowering and fruiting plants. Here are the five types of Marigolds you may want to plant in your garden.

French marigolds release toxins that kill and repel white flies and harmful nematodes. They are said to be the most effective natural pest control.

Insects can detect VPCs, and some VPCs attract pests. Fortunately for French Marigolds, it is the opposite that happens.

When insects smell the plant's VPC, they immediately turn away. They could die if they are within the radius of the soil.

An ideal time to plant them is at the end of the growing season, so you'd be able to safeguard the plants yet to develop. This will ensure that the plants at the next season will bloom and thrive.

Root-Knot Nematodes

NEMATODE ROOT KNOT

Root-knot Nematodes are often attracted to crops such as tomatoes and tomato plants (even before bearing fruit). You can recognize the infestation when you inspect their leaves.

The leaves would turn yellow, and they will wilt under the sun. Moreover, the effects are even more severe for developing plants.

The fruits and crops will also be smaller and deformed and may be unfit for harvest. Slowly, the plants will no longer be able to yield crops.

White Flies

White Flies are pests that suck the sap out of vegetable and ornamental plants. They are abundant in warm weather, so if you live in an area with a generally sunny climate, these are flies you need to watch out for.

They cause the wilting and yellowing of plants, making them unable to grow and yield. Additionally, they are just as destructive as aphids, so you'll want to get rid of them ASAP.

Planting French Marigolds would prevent an infestation from happening. It could be challenging to control these pests, so it is best to implement natural insecticides before they come.

Cabbage Worms

Fortunately, you can safely plant Marigolds beside your cabbages or leafy vegetable crops. They are common companions, and they deter cabbage worms effectively and safely.

Marigolds deter Cabbageworms because of the chemical alpha-terthienyl, which repels and eliminates the presence of the smallest worms and pests.

Not only will Marigolds be functional when placed near cabbages, but they will add visual appeal to your garden as the vibrant flowers liven up your crops.

Ideally, you shouldn't have to add chemical insecticides if the Marigolds are already releasing toxins that deter pests in your garden.
