Sowing in terrine: The steps

Sowing in terrine: The steps

Why make seedlings in terrine?

Seedlings in terrine are reserved for the most fragile crops, or the most difficult to achieve in the ground. They allow you to cultivate in a land suitable for cultivation, a "new" and clean land. You will manage the watering, and if necessary, the temperature, because some seedlings are done "hot".

How to make the seedlings in terrine?

  • Use a rather flat container, a “terrine” collected or bought in a garden center.
  • The terrine must have a hole in it, so as to allow good drainage and if possible have a lid.
  • Start by adding a draining layer such as gravel or coarse sand.
  • Add a layer of seedling soil, or other suitable growing medium, to the top of the container.

When sowing, watering is delicate because it is necessary to avoid moving the seeds.
A very good technique simply consists to wet the earth before sowing the seeds.
The smaller the seeds the more they will be sown on the surface, barely covered with potting soil. Conversely, pread the seeds are big, the more they will be placed deep.

  • Tamp with a board.
  • Carry out the sowing.At this stage, the seeds can be quite tight but not sticky. Once grown a few centimeters, the seedlings from the seedlings will be placed in a bucket.
  • Sift a thin layer of potting soil to cover the seeds (2 to 3 millimeters maximum).
  • Tamp down again with the plank. VSThis stage aims to make the earth very flat. In this way, the seedlings are never in contact with wet soil, preventing the development of moisture-related diseases.
  • To create a "greenhouse effect", let the terrine dry on the surface, then place a tightly sealed kitchen film on top - or a cover for garden terrines. The atmosphere created will be conducive to the rise of seeds, heat and saturation.
  • Once a day, aerate the terrine by partially opening the film or the lid, which helps prevent the development of fungal diseases.
  • Keep up the pace until the lift.
  • Store the terrine under a heated shelter (15 to 22 ° C) and without direct sunlight.
  • As soon as the first 2 "true" leaves appear, transplanting in a bucket (or even in the ground) is possible and even recommended. (See the tomato sheet). Transplanting in pots also helps strengthen the plants. Full transplanting therefore occurs with a much more mature, taller, more resistant plant.
  • Watch out for weather conditions. Adapt the transplanting according to the hardiness of the varieties sown.

Leek sowing: tips for success

Leeks are a widely consumed leaf vegetable, cultivating them in a vegetable garden has many advantages: it can be harvested throughout the year if the sowing is staggered and comes in many varieties, the choice is thus much wider than in commerce.


Sowing in a honeycomb terrine (or sowing in a honeycomb plate)

The alveoli terrine is a rectangular terrine made up of alveoli. It is suitable for sowing in large numbers, with different varieties of plants.

1- Fill the honeycomb terrine with seed soil, then level the surface using a plank.

2- Place in each cell one or more seeds on the soil.

3- Cover the seeds with a thin layer of potting soil and moisten the whole with a fine watering head. CAUTION, the seeds should not be covered more than once their thickness.

To facilitate emergence, place the alveolated terrine in a warm place and spray with water so that the soil always remains moist. Once the seeds have germinated, place them in the light (be careful not to direct sunlight), and continue watering with a spray bottle. When the seedlings are large enough to handle, transplant them each into a pot without damaging them with "potting" soil.


For sowing, 2 techniques are available to you:

  • Sow in place directly in the vegetable garden.
  • Sow in a bucket.

Generally, we choose to sow the courgettes directly in the ground.

Zucchini seedlings in place

  1. Meticulously weed your plot.
  2. Dig holes about 30 cm deep, four feet apart in all directions.
  3. Fill each hole with well-rotted compost and a handful of organic potash.
  4. Mix well.
  5. Insert 2 or 3 seeds per pocket about 1 cm deep.
  6. Tamp with the back of the rake.
  7. Water abundantly in fine rain and keep moist until the first leaves appear (normally between 5 and 8 days).

About fifteen days after sowing, it will be necessary to thin out.
Eliminate weaker plants to keep only one per pocket.

Zucchini seedlings in a bucket

We often practice zucchini seedlings in a bucket in order to save time and produce earlier.
However, it must be at least 14 ° c to hope to see your zucchini seeds germinate.
To do this, place your pots under shelters (greenhouse or frame) and start sowing zucchini as soon as temperatures are optimal.
Around the beginning of April north of the Loire, and March for the regions of the Atlantic coast.

  • Fill the pot with potting soil and lightly tamp the soil.
  • Make a hole about 1 to 2 cm high.
  • Place 1 seeds and close the hole.
  • Tamp lightly and water regularly until emerged.
  • Place your seedlings in a frame or greenhouse until planting in the vegetable garden.

Transplanting in the vegetable garden is usually done after the Ice Saints (mid-May) to prevent any risk of frost on your crop. This is a date that you can keep in mind as a benchmark when growing vegetables. It is possible to do it earlier, but it can be risky. If you live in the South East on the other hand, it is possible to plant in the ground a little earlier.

Voila, you know pretty much everything about zucchini seedlings. I hope this will allow you to have success with your crops this year.

How to sow in a terrine or box?

While the method is simple, it nevertheless requires attention to the heat, light and humidity conditions of the seedlings:

  • Install at the bottom of your boxes or terrines a drainage layer (pebbles or clay balls) then fill them with special seedling potting soil.
  • Sow the seeds and cover them with potting soil. Then tamp lightly.
  • Water with a mist sprayer. Cover with a transparent lid to maintain constant humidity. The soil should remain moist but not soggy.
  • Install your plantations in a very bright and warm place.
  • As soon as the first leaves appear, remove the cover and make sure that the seedlings have as much light as possible (natural or artificial light).
  • If you have sown too densely, do not hesitate to thin out your plants before transplanting them.


Harvesting the seeds: (see article)

At the end of summer, collect the seeds when the weather is nice. It is necessary to wait until the fruits are dry, watch out for the wind which disperses the ripe seeds.

We must act in time. Let the seeds dry in a cool and dry place (15 ° C), then store them in envelopes in airtight boxes, protected from light.

Consider putting labels with the name or photo, and the date.
