Sowing in seedbed

Sowing in seedbed

In this video, we describe the necessary materials (which you will find in our shop) and the steps to follow to enjoy your own vegetables!

Necessary material:

  • Seedbeds or Alveoli: for smaller plants, which have less root development.
  • Pots: for larger plants, which will need to develop their roots more.
  • Seeds: of the vegetables that we want to cultivate. On our website, you will find a long catalogue of organic seeds such as those shown in the tutorial.
  • Substratum: soil for seedlings. The substrate must have the following characteristics: it must be spongy to favour the root development of the plants, it must retain humidity well, so that we avoid ensuring a continuous availability of water for the seedlings without the need to water too frequently, and it must provide the nutrients that the plant needs in its development phase. In our case, we use Royal Mix from Plagron, for its excellent results. Alternatively, we can recycle pots with substrate we have already used for cultivation, adding a little earthworm humus, which will improve both its nutrients and its structure.


  1. First of all, fill with substrate the alveoli or pots where you are going to carry out the sowing. The substrates are generally very spongy, you will have to press it softly with the fingers so that it is firm (without being excessively compacted), otherwise the plant will have more difficulty in putting down roots and we will have to be much more careful when watering to avoid that the water empties us of substrate the alveoli.
  2. Once the alveoli or full pots, we will practice a small hole with the finger, where we will introduce the seeds that we are going to sow. It is not necessary that the hole is very deep, with two or three centimetres it will be enough for the seed to be well buried.
  3. Introduce the seeds. It is important to know the vigour of the plants we are cultivating, to calibrate the number of seeds that can be introduced in each alveolus or flowerpot. For those plants that have good germination, such as tomatoes or legumes, just one seed per hole will suffice (if we fall any more do not worry, we can always clarify the plants once the seedlings have grown). In the case, for example, of lettuces, it will be better to pour three or four seeds per alveolus to ensure that we will have the desired number of seedlings to transplant when the time comes.
  4. Cover the holes by pressing gently with the soil of the alveolus itself.
  5. Water the pots or alveoli, as always when sowing. In this way, the seeds will be activated and begin their germination.


If we have carried out the sowing very early to be able to transplant as soon as the low temperatures are finished, it will be convenient for us to maintain our nursery protected from the cold. For it, we can choose the sunniest and protected corners of our terrace or garden or use mini-greenhouses.

We water every two or three days, always in small quantities, to ensure that the substrate remains moist, but avoiding waterlogging, which could cause the seeds to rot.

All we have to do now is wait for the seedlings to come out and for the heat to reach us so that we can transplant them in our orchard!

In we want to provide you with everything you need, material and knowledge so that you can turn your patio or terrace into an ecological garden for your health and well-being.
