There are two ways to get the tomato plants needed for planting: acquire in any store dealing with farming products and usually are already highly developed, bringing the roots wrapped in a piece of substrate which doesn't interrupt the development process for being transplanted, or alternatively, you can acquire initially seeds, which are also available in these establishments, in small packages, which can be seen the reference range and the description of their characteristics.
Small tomato seeds, also can be obtained, if desired, from some previously selected tomatoes, leaving them ripen until they are soft, juicy and red. Faced with the possibility of inclement weather will be advisable to harvest them, to avoid rot because of the rain and leave them a few more days in a dry and airy environment so that the maturation process is completed fully, but only if it is quite mature already. Next, cut them to remove the tomatoes pulp which lodges the seeds, spread it on a plain place, allowing it to dry in the sun, one or two weeks or in a dry and ventilated place, then keep it in a dry closed container.
Seeding the beds of tomatoes, the sooner it are done, the sooner the plants will be available for planting, usually they're done at the beginning of February to be available for transplant at the beginning or at the middle of March, and we can make a small bed rich of substrate moistened with a little water on a sheltered location with good sun exposure or using a small box-shaped tray made of styrofoam, because the thermal properties of this material, by covering with a little plastic allows to develop a greenhouse while maintaining a temperature inside, which it's an advantage to adequate germination and plant growth.
