How to grow petunia from seeds?
Petunia is one of the favorite flowers of summer residents. She is loved not only for the beauty of the flowers and the variety of varieties, but also for the long flowering, throughout almost the entire summer season. But most people buy seedlings and don't even know how to grow petunias from seeds. Meanwhile, this is not such a troublesome business, you just need to know a few subtleties. Small petunia seeds germinate better in the light, they do not need to be embedded in the soil. You can buy soil for growing seedlings in the store, universal, but add sand to it. Place some kind of drainage on the bottom of the seedling box (or a disposable container, some kind of bowl with holes for water drainage), pour the prepared substrate on top.
So that the petunia seeds lay on the ground evenly, I do this. I pour the snow on top of the ground, sprinkle the seeds on it, and then spread them over the surface of the snow with a toothpick. Next, I make a mini-greenhouse from the seedling box using glass or polyethylene, and put it on the window. The snow melts and the seeds end up on the substrate. As a rule, seedlings are sown in March, we still have snow at this time. In a region where there is no snow, the seeds can be mixed with sand and then scattered over the surface of the ground, then make a mini-greenhouse.
Until shoots appear, the soil in the mini-greenhouse is moistened by spraying. Seedlings will appear in 10 days. After they appear, the temperature of the content should be lowered by a couple of degrees, and the mini-greenhouse should be ventilated daily to remove condensation and avoid contamination of the plants with a black leg. When the seedlings get stronger, and they have several real leaves, they are seated in separate containers. Seedlings are planted in the ground when the threat of night frosts has passed. That's the whole simple way of how to grow petunia from seeds.
