Marigold cultivation methods and precautions

Marigold is an annual herb with a short and strong plant and brightly colored flowers. Marigolds are often sown in spring. Because of their large flowers and long flowering period, they are generally used for flower bed decoration and can also be grown in potted plants for viewing. Below, the editor will introduce the cultivation methods and precautions of marigolds. Let’s take a look.

1. Soil

Marigold is not very demanding on the soil. Just choose loose soil with good drainage and air permeability, such as sandy soil or garden soil. This type of soil has good drainage, which can avoid water accumulation in the pot due to excessive watering, and can also effectively avoid root rot caused by water accumulation.

2. Temperature

Marigold is suitable for growing in a warm and humid environment. The most suitable temperature is 15-25℃, and the suitable temperature during flowering is 18-20℃. It can be grown outdoors in spring and autumn. Due to the high temperature in summer and the low temperature in winter, the marigold needs to be moved back indoors to avoid high temperature burns and low temperature damage.

3. Lighting

Marigold is a sun-loving and light-loving plant. During normal cultivation, marigolds can be placed on a balcony or in a well-lit room for maintenance. In summer, pay attention to controlling the light intensity and time. The light is too strong in summer, so marigolds must be shaded, otherwise the flowers and leaves of marigolds may be burned. When there is insufficient light in winter, some light should be added to promote the growth and development of marigolds.

4. Watering

Marigolds can be watered once a day during the seedling stage. Be careful not to water too much to avoid water accumulation. In the later stage of maintenance, you can water the soil according to the dryness of the soil. Water it when it is dry and water it thoroughly when you do. Watering should be stopped in winter.

5. Fertilization

Marigolds can be fertilized every 20-35 days during their growth period, using a thin cake fertilizer water. Fertilize once every 60 days before and after flowering, use compound fertilizer water, and apply thin fertilizer frequently. Stop fertilizing during the dormant period to avoid fertilizer damage.

6. Pruning

Marigolds need to be pruned and shaped regularly during the cultivation process. They need to be topped in the seedling stage, and the top branches and leaves need to be cut off to promote the germination and growth of side branches. When the plant is growing vigorously, it is necessary to promptly cut off the messy branches, overlapping branches, and overgrown branches.

7. Notes

Check the plants regularly to detect and treat any pest or disease problems promptly. Use appropriate control methods, such as hand-picking pests or using organic pesticides .

The above are the methods and precautions for growing marigolds. Marigolds like plenty of sunlight and require at least 6 hours of direct sunlight a day. Also, keep the soil moist, but avoid overwatering, which can cause root rot.
