Dates for planting seedlings in polycarbonate greenhouses

When to plant cold-hardy plants

After reading information on various forums about when to plant seedlings in a polycarbonate greenhouse, you'll see that this work is done in May. Therefore, by early May, your greenhouse should be ready to welcome its "new residents."

Cold-hardy vegetables can be planted in a polycarbonate greenhouse (if it's not additionally heated) as early as mid-spring. These include parsley, dill, and various lettuces. Radishes, Chinese cabbage, turnips, and mustard will also thrive in these conditions.

Growing tomatoes and cucumbers

When considering when to plant seedlings in a polycarbonate greenhouse in the Moscow region, many gardeners don't consider that different vegetables require different growing conditions. For example, cucumbers and tomatoes are the most common vegetables in our gardens. If you plant cucumbers in the same greenhouse with tomatoes, eggplants, or peppers, you won't have to worry about a poor harvest of green vegetables.

Greenhouse conditions The following conditions are required for growing cucumbers: daytime air temperatures of 26-28 degrees Celsius and nighttime temperatures of at least 19 degrees Celsius. Humidity should be 90%, and inter-row irrigation should be used during flowering.

Greenhouse conditions for growing tomatoes require lower daytime temperatures, 24-25 degrees Celsius. Humidity should not exceed 70%. Unlike cucumbers, which thrive in humid air, tomatoes prefer to grow in relatively dry conditions but moist soil.

Free space for everyone

When planting seedlings in polycarbonate greenhouses, it's important to ensure each plant has sufficient space. If the plants are overcrowded, the risk of various diseases or pests increases dramatically.

A path is, of course, a must. It can be mulched, but only for aesthetic purposes. In general, in polycarbonate greenhouses, the path can be paved, and the beds can be enclosed with a moisture-resistant material.

Mulching is not necessary in a polycarbonate greenhouse, which is a huge advantage over film-based options. Eggplants, tomatoes, and peppers can be planted in the same greenhouse. However, care must be taken to ensure that the plants do not shade each other. Peppers are recommended to be planted in the first row from the walls.

Important! Complementary crops, such as greens and salads, can be grown in a greenhouse only until early summer. They can then be sown after the main harvest.

To briefly answer the question of when to plant seedlings in a polycarbonate greenhouse, May and June are the preferred months for all regions of the country. April is also a good time to plant certain crops in greenhouses, but these will be greens, radishes, and various types of lettuce. Wishing you a wonderful, fruitful summer.
