Coriander germination time

After planting the coriander seeds in the soil, take good care of them and they will normally germinate in 17 to 18 days, or 20 days later. However, if you germinate the coriander seeds in advance, they will generally germinate in about 12 to 14 days.

Coriander sowing time and method

1. Sowing time: Coriander is a common plant. The best sowing time is from May to June each year. The temperature during this period is relatively suitable, not too cold or too hot, which is most suitable for the growth of coriander.

2. Seed selection and land preparation: Choose coriander seeds with smaller leaves, stronger fragrance, and full and healthy appearance. For land, choose fertile and breathable soil, and then deep plow the soil to a depth of about 23 cm. Dry it in the sun for about half a month, and then add cake fertilizer, decomposed feces, and phosphate fertilizer as base fertilizer.

3. Soak the seeds: After selecting the coriander seeds, you need to process the seeds. You can soak the seeds in 300 times the concentration of 1% carbendazim solvent. After soaking for 25 to 30 minutes, wash them with tap water, and then soak them in clean water for about 25 to 30 hours.

4. Germination and sowing: After soaking the seeds, put them on a wet towel to germinate. Control the temperature at around 24°C. Turn the seeds over twice a day. After 4 days, you can sow them. When sowing, first wet the soil, then sprinkle the seeds on it, and then cover it with a thin layer of soil.

How to manage coriander after it sprouts

1. Water and fertilizer: After the coriander seedlings emerge, it needs to be watered every 7 to 10 days. If the coriander grows well in the later stage, no fertilizer is needed. If the coriander loses its color, organic fertilizer or phosphorus fertilizer needs to be applied. After rooting and sprouting, it needs to be placed in the sun.

2. Pests and diseases: When coriander is in the seedling stage, it is easy to be harmed by pests such as aphids and leafminers, or suffer from diseases such as sclerotinia and gray mold. It is necessary to clean the surrounding weeds and spray pesticides every half a month.
