Tomatoes beds

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.

Bordeaux mixture preparation

The formulation below is to make 10 liters, to make other quantities just keep the proportions between the ingredients. The "bordeaux mixture", calda bordalesa, is made of a dissolution of copper sulphate and lime water.

a) Dissolution of copper sulphate(1 liter):
The day before and four hours before the mixture’s preparation, dissolve the copper sulfate. Pour 100 g of copper sulfate within a cotton cloth, tie and dive into a plastic container with 1 liter of warm water;

b) Lime water:
Pour 100 g of lime in a bucket of 10 liters capacity. Then add 9 liters of water slowly.

c) Mixing of the two ingredients:
Add gradually and always stirring, the copper sulphate solution (1 litre) into the lime water bucket.

d) Test of the knife:
To see if the final mixture is not acidic, we dive a clean knife made of common steel for 3 minutes in the final mixture.
If the blade is dirty, which means it acquired a brown color when removed from the mixture, indicates that the solution is acidic. It should be added more lime in the mix, but if not dirty, the “bordeaux mixture”(calda bordalesa) is ready to use.
