Preparation of annual plants for transfer to the ground does not only include potting and quilting. The hardening of the seedlings is also very important. This process will help the plants to become resistant to low temperatures and difficult weather conditions. Learn how to harden your seedlings properly.

Planting plants can be divided into two groups: plants from sowing and seedlings. The latter is prepared in greenhouse conditions as early as February or March. The aim is to allow the annual plant to take root in the pot. What do I need to do after placing the seedlings in pots?

Before hardening - quilting

Regularly watered and hot seedlings should grow within a few weeks. When this happens and the plants already have a few leaves, quilting should be carried out. It consists in replanting seedlings into larger pots, in which there will be room for growth.

Plant hardening - what is it?

After quenching the seedling, when the seedling is over a month old, there comes a time for hardening. It consists in immunizing the plant and preparing it before transplanting it to the ground. Increases the chance of seedling acceptance and its proper development.

How to perform seedling hardening?

The hardening of plants should be carried out gradually. First, place the plants on a window sill with the window open and leave them there for about an hour. It is important that it is not exposed to strong gusts of wind and strong sunlight.

Then extend the time at which the seedlings are placed with the window open. Then you can leave it there all day long. For the night, we advise you to take her back inside.

Effects of the hardening of seedlings - what can be seen?

Plants from seedlings that have become accustomed to low temperatures are more resistant and have a better chance of survival after being moved to the ground. Some of the changes can be seen with the naked eye - the leaves become darker, the stems and leaves look stronger and thicker.

When to harden the seedlings?

It is best to do it about 10 days before the planned movement of the seedling to the ground, i.e. from the middle of April to the beginning of May. Before this day comes, make sure that the soil on which you want to plant the seedlings meets the requirements of the plants. To fertilize the soil, you can also add a universal substrate to your allotment soil.
