Coriander Not Sprouting? Here Are the Latest Solutions

Coriander is a very common vegetable in our daily lives, and it is grown on a very large area in our country. Although coriander cultivation techniques are relatively simple and yields are fairly high, when growing coriander you will often run into the problem of coriander seeds failing to sprout after sowing. So if coriander seeds do not sprout, what should we do? Below, the editor will give you a brief introduction. Let's take a look!

1. Breaking the seed shell

Coriander seeds may fail to sprout because the seed shell was not broken open. On the market today there are generally two kinds of coriander seeds: unbroken and already broken. If the seeds have already been broken, they will look rather fragmented, and the shells will have cracks. If they have not been broken, the seeds are plump and round, and the seed coat is fairly smooth. Therefore, for this kind of seed, you need to break the shell: put the seeds between two flat surfaces such as pieces of cardboard and rub them, or rub them in sand. Pay attention to the force - do not press too hard, or the kernel inside may be damaged; just make sure the shell cracks.

2. Seed treatment

After the coriander seeds have been broken open, to improve the germination rate we also need to do a good job of pre-sprouting. Wrap the seeds in a damp cloth and soak them in water for about two days, changing the water once partway through. After soaking, drain off the water, then spread the seeds out flat in a cool, shaded place to pre-sprout, keeping the temperature at around 20 degrees during pre-sprouting. Alternatively, after soaking, the seeds can be kept at around 10 degrees for about 3 days, which can effectively raise the germination rate. At the same time, to avoid damage from pests and diseases, we should also use a disinfecting solution such as Xinguozhimu (new high-fat film) to dress and disinfect the seeds.

3. Sowing at the right time

Coriander cannot be grown in successive crops on the same land, and repeated cropping will also seriously affect the germination rate of coriander. So when sowing, the plot must be guaranteed not to have grown coriander-type plants for at least three years. At the same time, do a good job of land preparation and disinfection. Before sowing, water the soil thoroughly and apply sufficient base fertilizer. Then break up the clods of soil to make the soil looser, and form beds ready for sowing, which is very beneficial for the seeds to take root and sprout. When sowing, pay attention to the weather - do not sow under blazing sun. After sowing, cover with soil and spray an appropriate amount of Xinguozhimu, and in strong light conditions also cover with plastic film.

4. Strengthen management

Even after the above treatments, coriander seeds generally still need about two weeks to sprout after sowing. Without treatment, the sprouting time may be as long as a month, and the germination rate will be greatly reduced. Therefore, during the sprouting period, if the soil is fairly dry, pay attention to watering appropriately. Then after sprouting, do a good job of watering and weeding, and when the seedlings have grown to about 7-8 cm, fertilize appropriately to improve the survival rate of the seedlings.

The above is a brief introduction to what to do when coriander does not sprout. That is all for today's introduction. This article is for reference only, and we hope it can help you!
