1. Soil requirements: the soil requirements are not strict, which can adapt to various soil types and grow well on acidic soil. Because the seeds are small, the soil in the flowerpot needs to be leveled into fine soil.
2. Sowing time: The best sowing time for clover is spring and autumn. Spring sowing can be conducted from the end of March to the end of April. Sowing can be conducted when the temperature is above 15 ℃. Sowing in autumn is generally in the middle and late September.
3. Sowing: clover seeds need to be soaked before sowing. Add 1.5kg of water for every 1kg of seeds, and 1g of ammonium molybdate for 12 hours. Mix 5-10kg of calcium magnesium phosphate fertilizer with 5-10kg of fine soil or 5-10kg of yellow sand before sowing. Seedlings can be seen about 3 days after sowing.
4. Precautions:
(1) The temperature suitable for clover is about 15 to 25 degrees centigrade, which should not be lower than zero. Avoid strong light exposure, otherwise the leaves are prone to yellowing, and water accumulation should also be avoided.
(2) In terms of fertilization, phosphorus fertilizer and potassium fertilizer are mainly used. Nitrogen fertilizer is not needed too much, and clover also needs to be repaired frequently to grow new buds.
