Some kind of special knowledge and effort growing salvia from seed does not require. But still, each plant has its own characteristics.
When growing salvia, it should be borne in mind that the seeds will need to be sown in February-March. Therefore, seedlings from seeds must be grown in advance.
Salvia does not have any special requirements for the soil for planting, the main thing is that it is light and nutritious. Salvia seeds are very small, so you should not bury them deeply in the ground. It is enough to scatter them over the surface and sprinkle them on top with a layer of earth.
After planting, spray the soil in the planting containers with warm water from a spray bottle. To create a greenhouse-like environment, cover the containers with glass or plastic. Further - the expectation of shoots.
As soon as the first shoots appear, the boxes must be placed in a well-lit place or supplemented with lamps. Daylight hours for seedlings should be at least 12 hours a day.
Watering Salvia seedlings should be done carefully, avoiding severe drying out of the soil and its excessive waterlogging. Two weeks after the emergence of shoots, the salvia can already be fertilized.
After a pair of true leaves grow on the plants, they must be cut into separate containers.
As you may have noticed, growing salvia from seed to seedlings is similar to growing many other garden flowers, all the techniques are probably well known to you. Transplant the resulting seedlings into open ground when the threat of frost has passed.
