How can marigold grow well?

1. Matrix requirements: Marigold should be planted in soft and breathable soil with good drainage and rich organic matter. 2. Water management: thoroughly water the soil after it is dry. 3. Light and temperature control: control the curing temperature of marigold at 14- 16 degrees and provide it with sufficient sunshine. 4. Supplement fertilizer: apply calcium and potassium fertilizer to marigold once every half month.

How can marigold grow well? 1, substrate requirements

When planting marigold, you must use soft, breathable, well-drained soil rich in organic matter. Peat soil, perlite and river sand can be mixed together in equal proportion, and calcium superphosphate can be added to make nutrient-rich culture soil.

2. Water management

Marigold is a plant with strong drought tolerance. When watering, you should follow the principle of dry and thorough watering, but you can't wait until the plants wilt and there is no water in the basin, otherwise it will easily make the roots retch and affect the healthy development of marigold.

3, lighting temperature control

The suitable temperature for papaya growth is 14- 16 degrees. If it exceeds this range, the flowering of plants will be delayed, and enough sunshine should be kept during the growth period of papaya, otherwise the branches will become thinner and the leaves will become thinner.

Step 4 supplement fertilizer

After marigold enters the peak growth period, the mixed fertilizer of calcium nitrate and potassium nitrate should be applied to it once every half month to meet the demand of plants for calcium, and the fertilization should be stopped until the flower buds are formed.
