March is a great month to plant tomato seeds for seedlings.
But what days are best to do this? Here you need to focus on the lunar calendar. It is believed that planting is best done on the days of the waxing moon. In this case, the growth and development of plants will be good.
As for the new moon and full moon, on such days it is better to avoid working in the garden and vegetable garden, and it is advisable to keep all gardening chores to a minimum.
Good dates for planting: March 3 and March 29-30.
Less successful days: March 11-12 and 20-21.
You need to prepare high-quality soil and fill wooden trays or boxes with it. You can immediately place the plantings on the windowsill. But you need to ensure that the seeds do not freeze.
It wouldn't hurt to install additional light. After all, tomatoes need at least 10 hours of sunlight a day, but ideally 12-14 hours.
As soon as the first leaves appear, the seedlings can be transplanted into separate containers so that the plants do not interfere with each other.
