How to germinate tomato seeds step by step

Follow these tips and steps to germinate tomato seeds:

  1. To start, and of course, you will need tomato seeds. You can use tomatoes from the supermarket without any problem, of the variety you prefer, although you will always have much better results with tomatoes from organic crops.
  2. The next thing will be to prepare the seedbed or container pot. Tomato seeds germinate much more easily in a controlled environment, so it is best to do it indoors, and later, if necessary, transplant them. It is necessary that the container has drainage holes: if it does not have them, make them.
  3. The substrate is very important: the ideal is to prepare a mixture with one part of peat, another part of earthworm humus and a third part of coconut fiber. Then add vermiculite and perlite to the mixture and stir well. This results in a very light substrate, with excellent drainage and very nutritious, as well as good moisture retention properties. Water to add moisture after mixing.
  4. When sowing, you can carefully scoop out the seeds from the tomato itself with a teaspoon, or use an even more natural method and cut the tomato into a few slices, leaving the outermost one on each side aside (don’t throw them away! They’re delicious!) and sow, instead of the seeds, the tomato slices themselves with these inside. In either case, don’t plant too deep, as the small tomato seeds will have a hard time reaching the surface then; tripling the thickness of the seed itself in the substrate is more than enough.
  5. After sowing, water again with a sprayer so that the water does not drag the seeds, and put the seedbed or pot in a warm and shaded place until the tomato seedlings begin to emerge, at which time you should move it to a lighted area .

Y when to germinate tomato seeds? Indoors you can do it throughout the year if you control the temperature at which you expose them, since the seeds and seedlings cannot withstand temperatures below 15ºC. However, the best time to do this is between late winter and early spring.
