How to save seeds of petunia

Petunia seeds

In principle, it is very difficult for petunia to produce seeds on its own. Only artificial pollination can be carried out during the flowering period of petunia, so that it can produce more seeds.

Petunia Seed Saving

After harvesting, petunia seeds need to be placed in a dark environment. It is best to dry them and then refrigerate them. If they are sown in time after harvesting, the survival rate will be higher. They should not be stored for too long.

Petunia Seed Planting

Petunia likes a warm environment and is suitable for sowing in spring from February to March. The suitable germination temperature is between 18-25 degrees, and the most suitable growth temperature is between 22-34 degrees. It can bloom in summer if sown in spring, and the growth rate is very fast.

In addition, you should choose suitable soil when sowing. You can use garden soil, leaf mold and a little sand to prepare flower soil. Before sowing, you can water it thoroughly once. After sowing, you must ensure the moisture of the seedlings to avoid affecting the germination rate due to the flower soil being too dry.

Before sowing petunias, you must first buy seedling blocks, let the seedling blocks absorb water, then dip the seeds in water and put them into the small hole in the middle, wait for them to sprout, and then plant them in a paper cup with holes at the bottom. Water them once in the morning and evening every day. When the seedlings grow a little bigger, you can transplant them into pots with soil.
