Marigold cultivation methods and precautions

Farming methods

Temperature and light

Marigold prefers a warm, humid and well-lit environment. The suitable growth temperature is between 20 and 30°C. The summer temperature should not be higher than 30°C, and the winter overwintering temperature should be above 5°C. It is necessary to ensure that marigolds have sufficient sunlight to bloom beautifully. If there is insufficient light, the plants will easily grow too tall, which is not conducive to flowering.

soil

Marigold is not very demanding on the soil, and loose sandy soil with good air permeability and drainage is preferred.

Watering and fertilizing

Marigolds need to be watered frequently during the growing season, but the amount of water should not be too large each time. Just water when the soil is dry. When watering, you should change the watering method according to the changes of seasons. Water in the morning in summer and autumn, and water at noon in winter and spring.

Fertilizing marigolds should be done moderately. A fixed amount of base fertilizer should be applied when planting, and liquid fertilizer should be applied once a month during the growing season. Do not apply too much nitrogen fertilizer to avoid excessive growth without flowering.

Precautions

Reproduction

Marigold is mostly propagated by seeds, which can be sown in spring and transplanted after seedlings are raised. It can also be propagated by cuttings in summer.

prune

After transplanting marigolds, you can pinch the tips to promote more branches and more flowers.

After marigold blooms, it is necessary to cut off the withered flowers in time and cut off the dense branches and leaves to sprout new branches and promote more flowering. It can also promote the growth of aerial roots of marigolds. When the aerial roots grow stronger, you can cut the marigold from the stem and replant it. You can also use heavy pruning to press down, but heavy pruning can easily affect the growth of the plant, resulting in poor growth of branches and leaves, and poor flowering.

Pest control

Marigold has relatively few diseases and pests, the more common ones are leaf spot, damping-off, powdery mildew, aphids and leaf miners. Drugs can be used for prevention and treatment.
