French marigold

French marigolds are very popular, well-known annuals and a must-have for your garden. They can be grown in pots or in flower beds and borders. French marigolds can assist in stopping nematodes, ants and whiteflies. Put some French marigolds in your vegetable garden in-between carrots, onions, leeks, cabbages and other plants vulnerable to whiteflies and nematodes. Deadhead often. These annuals are long flowering and bright coloured. French marigolds flower from late spring till the frost.
