Question: sowing

good morning,
I sowed about 2 weeks ago seeds of the blue dwarf agate, but nothing has grown yet. How long does it take before something is born? sowing is at a window that acts as a greenhouse effect

Answer: sowing

Dear Katia,
sowing is a very pleasant activity that gives great satisfaction; in addition to this, sowing our plants also allows us to obtain large numbers of them from a small bag of seeds.
That said, not all seeds germinate in a short time, and often the climatic and bright conditions cause delays, even very large ones, in the germination itself.
Therefore, usually the agate is sown in February-March, in a heated or sheltered seedbed, where the minimum temperatures never fall below 12-15 ° C; if the climate is decidedly colder, below 5-8 ° C, then the seeds await a more propitious moment to sprout, because otherwise the tender newborn leaves would be immediately ruined by the cold.
It is often believed that the seeds, once placed on the sowing ground, should then be covered; in fact most plants drop their seeds on the bare ground, and these sprout more quickly when they are well lit by sunlight. An ancient saying says that plants sprout more quickly when they hear the bells, or when they are exposed to the air and not underground.
Therefore a covering, even thin, of soil, often delays the germination of the seeds.
In nature, most of the seeds begin to sprout in spring, when the climate is warm, but above all humid: it is an alchemy of days that stretch and fresh rain that warns the small seeds that the summer is coming.
For this reason, our winter or spring seedbed must be placed in a very well-lit place, possibly with a few hours of sunshine every day, and it must always be constantly humid.
Proceed by wetting the compound immediately, before sowing; the ideal is to have a low seedbed with holes in the bottom, so that it can be placed in a saucer: as soon as the seedbed is full of earth, we fill the saucer and let the water intertwine all the substratum well, by capillarity .
To avoid moving the delicate seeds, in the following days we will go to water using a vaporizer.
It is essential to keep the soil always moist, because even with dry soil one day it could kill the young shoots.
There are even those who cover the seeds with a gap of millimeters of vermiculite, it is a granular, light-colored material, which in addition to allowing the sun's rays to hit the seeds, also maintains a little moisture always present on the surface of the ground; to further increase humidity, a plastic film is also used, to be positioned above the seedbed, so as to keep it hermetically closed: in this way the humidity that evaporates from the soil will fall back after having condensed on the plastic film.
