French Marigold Seeds
The French marigold is a must-have for every garden. The plant acts as a natural pesticide, which makes them great for use in companion planting. They are excellent at deterring nematodes and other pests. Nematodes are worm-like bugs that live in the soil and attack the root systems of plants. The flowers will also deter whiteflies and some species of beetles. While marigolds are not the perfect solution in preventing all pests, it’s an integral plant for companion planting. A garden should have various herbs and flowers to attract a wide range of predator insects. Predator insects are essential as they will prey on all sorts of garden pests.
How to Germinate Marigold Seeds
French marigold seeds are relatively easy to germinate. The seeds can be started indoors six weeks before the last expected frost date. If starting the seeds outdoors, you can sow them a couple of weeks after the last frost date.
They prefer a sunny location with moist, well-draining soil and with a pH of 6.5 to 7. The optimal germination temperature for the seeds is 23°C / 73°F. Surface sow seeds and lightly cover with soil. Keep the soil moist, but never soggy, and never let the soil dry out. If the soil dries out, the seeds and seedlings will die.
