Planting the greenhouse depends on the desired type of use. The article shows you how to successfully plant your seeds in the soil and what care measures young plants need as a result. Because: The more professional the sowing, the higher the harvest yield.

There are a number of things to consider when planting in a greenhouse

When everything is in place after assembly, the accessories have been placed and the right amount of light, shade and warmth has been provided, then planting the greenhouse is the most beautiful task. the Soil is prepared, get the seeds and a few sacks of substrate soil are also ready.

High quality seed for good growth

The tip for all those who want to harvest seeds from their grown plants themselves in the future: Be sure to use seed-resistant varieties instead of hybrids for the first sowing. Hybrid plants have the advantage that the harvest will be plentiful in terms of quantity. However, the seed obtained from these plants also fundamentally changes the genetic properties of the next generation and should therefore not be used for breeding.

Seed germination does not last forever

It is therefore better to ensure that the seeds used come from the last harvest if possible. Many manufacturers now offer plant seeds in so-called germ protection packaging. As long as the packaging remains unopened, the contents can usually can still be used without hesitation even after several years. Some examples of germination during professional storage in the following table:

plant type Germination (years)
dill 2 to 3
beans 3 to 4
onions 3 to 4
radish 4 to 5
Cabbage & Kohlrabi 4 to 5
tomatoes 2 to 6
lettuce 3 to 4

Greenhouse planting with the sowing

There are certainly few greenhouse owners who fill their house with purchased plants. So the first step is sowing, for which there are two different methods:

  • raising young plants in containers (pots or bowls) made of plastic or clay;
  • the future young plant culture is sown directly in the greenhouse soil at the final final distance from the start.

In both cases, your substrate should not be excessively wet when planting in the greenhouse, but only moist - not just superficially. The seed is now placed evenly on the ground and as precisely as possible at the distance that the young plants should later stand. Older seeds can be scattered more densely, since not every seed grain may sprout. With a wooden board, the seeds are now carefully pressed down to the ground and "seed thick" covered with loose greenhouse soil. For planting and other peculiarities of the different crops, in addition to being on the safe side, also refer to the description on the back of the seed packets.

From watering and transplanting to germination

This would be the first area of the greenhouse. At the end, it is now carefully watered without directing the watering stream directly onto the seed. So that the moisture in the soil or the substrate stays longer, the cultivated area can now be covered with two or three layers of garden fleece. Then you have to wait a few days before pricking out. You can tell when the time is right when the seed begins to sprout slowly but surely. Different speeds in sections and with mutual constriction. Very finely germinating seeds are now removed from the bed, but those that shoot up should also be removed, so that this work should be done with a little gardening skill and a little experience. In this way you create the basis for high-quality planting in the greenhouse, which ends as productively as possible at the end of the vegetation period.

Legitimate question: What to plant and when will what germinate?

For a rough orientation, here is a small overview, which we have also upgraded for you with the optimal germination temperatures. When planting in the greenhouse, it is advantageous to adhere to the to maintain the corresponding temperature values precisely.

Seed (plant) species Germination time (days) Best germination temperature (°C)
tomatoes 5 to 15 20 to 25
paprika 10 to 21 about 25
lettuce 6 to 10 15 to 18
cucumbers 5 to 14 25 to 28
Nasturtium 7 to 14 20 to 25
celery root 14 to 21 22 to 28
onions 14 to 28 18 to 25
beans 7 to 10 about 25
Parsely 12 to 21 about 25
leek 12 to 28 about 20
sage 14 to 21 20 to 25
marjoram 21 to 28 20 to 25
basil 14 to 21 20 to 25
artichokes 14 to 21 about 22
pumpkin 5 to 12 25 to 28

Greenhouse planting also means occasional fertilization

In the first few days, seedlings feed on their own reserves, after which it goes to the nutrients from the soil. If set correctly, it contains everything the future young plant needs to grow. Depending on the type of plant, phosphate, nitrogen and/or potassium oxide can also be added to growth-promoting soil for propagating or seeding soil that has been purchased. A lack of nutrients when planting in the greenhouse can be recognized by the sudden slowdown in growth and the leaves that appear somewhat pale. This helps to prevent such symptoms Addition of organic fertilizers. However, the doses must be given in good time, as the nutrients need some time in the soil before they are available to the plants.

tips

Watering yes, but without causing major clogging in the young plantings. Leave the freshly planted parts of the plants above ground as dry as possible at night in order to prevent fungal diseases from settling in the early stages. And finally: stagnant rainwater that is not too cold is the key when planting in a greenhouse!
