Coriander can be planted all year round. Coriander can be planted in open space, greenhouse or flowerpot. Now many people in the city have begun to grow coriander on the balcony.

Good seedlings of coriander are difficult to grow, mainly because the shell of coriander seeds is hard, and soil moisture is difficult to penetrate into the seed cm. If no measures are taken, the germination rate of coriander is extremely low. In rural areas, farmers planted coriander to improve the germination rate of seeds by accelerating germination. There are three common methods to accelerate germination. Friends who want to grow coriander can learn from it:

(1) Accelerated germination in refrigerator

Rub the hard shell of coriander seeds before sowing, then soak the seeds to accelerate germination. Friends who grow coriander in a large area usually soak the seeds with chemicals first, then clean the surface of the seeds after soaking, then soak them in cold water for about 10 hour, finally take out the seeds, clean them again, dry them, wrap them with wet rags or put them in a refrigerator with a constant temperature of about 10 degrees. It usually takes 5-7 days, and about 30% of the seeds can be sown after they turn white. When seeds germinate in the refrigerator, pay attention to frequent cleaning and turning.

(2) Well water promotes germination.

Coriander is a cool vegetable, and we can also use well water to accelerate germination. The specific method of accelerating germination is as follows: soak coriander seeds in cold water for 3-5 hours, then take them out and put them in a bag. Then put the bag in a well about 8 cm above the water. After 5-7 days, the coriander seeds will germinate. When about half of the seeds are found to be white, they can be sown in time.
