At the mention of French marigold, one might think it is a herbaceous plant that looks like a peacock, but it is not. It is an annual herbaceous flowering plant of the Asteraceae family. Its flower colors are not as brilliant and colorful as other flowers, but rather somewhat dark, which is one of its distinguishing features. Let's take a look at how it is planted.

How to Plant French Marigold Seeds

1. First, choose a box, pot, or other container, fill it with sandy soil, and create a loose and comfortable environment for the seeds to sprout.

2. Then scatter the seeds on the soil surface and cover them with a layer of straw, making sure the seeds contact the soil as much as possible.

3. Next, use a spray bottle to water the straw covering, letting the water slowly drip through the straw and soak into the soil.

4. Finally, wait quietly for the seeds to sprout. Only after the seeds germinate and seedlings emerge can the straw be removed.

Common Diseases of French Marigold and Their Prevention and Control

1. Its common diseases are mainly brown spot, powdery mildew, and stem blight, among which stem blight is the most common. It mainly harms the stems and leaves of French marigold. In the early stage of the disease, rash-like raised spots appear on the plant stems, gray in color and spindle-shaped or round; in the later stage, the rash-like raised spots crack open. Stem blight also occurs from time to time during the growing period of French marigold, and in severe cases it can cause the plant to wither and die.

Prevention and control methods: First, drain water promptly after rain to prevent moisture from lingering. Second, spray medication in the early stage of the disease. You can use a specific prepared solution of benomyl and cyclohexanone emulsifiable concentrate, chlorothalonil suspension concentrate, and Ludebao suspension concentrate. The spraying cycle is seven days, and spraying 2 to 3 times is sufficient.

2. Its common insect pests and their prevention and control: The common pest of French marigold is mainly red spider mite. Red spider mites pierce and suck the sap from stems and leaves, reducing moisture in the affected parts. Dense pale small spots appear on the leaf surface, and the leaves curl and turn yellow. In severe cases, the plant develops yellow leaves, curled leaves, scorched leaves, leaf drop, or even death. Red spider mite is also a transmission vector of viral diseases.

Prevention and control methods: Strengthen cultivation management. In the early stage of pest occurrence, you can use 20 percent dicofol emulsifiable concentrate at 500 to 600 times dilution for control.
