Vegetable sowing dates: when to sow seeds into the ground and for seedlings?

Vegetable sowing dates for different species vary not only due to due to their preferences regarding, for example, temperature or sunlight, it is also important is also important how we sow them – directly into the ground or from seedlings. Check when and which vegetables to sow into the ground, for seedlings or grown under cover (in inspections, plastic tunnel, greenhouse). See the calendar for sowing vegetables popular in Poland.

The sowing dates given are approximate and may vary slightly, depending on the variety of a particular vegetable.

Vegetables sown directly into the ground

In first sow those vegetables whose seedlings are resistant to low temperatures. It is important to sow them at the right time, because these vegetables do not tolerate late sowing well – they yield less or no yield at all. A longer day and higher temperatures cause them to release inflorescences, in addition, they are more vulnerable to pest attacks.

Good to know: some vegetables have a short growing season and are cold-resistant, so you can sow them in spring and autumn to ensure a continuous harvest. This applies to both vegetables grown from seedlings, as well as those planted in the ground, such as: lettuce, radish, radish, spinach.

• Spinach – March, first half of April

Sowing dates for vegetables grown from seedlings

Growing from seedlings allows you to get an earlier harvest, enables you to grow vegetables coming from warmer countries, where the growing season is longer, and also ensures crop continuity in the case of plants that have a short growing season vegetation period, and their seedlings can be replanted during cultivation (this is the case, for example, with lettuce).

Calendar for sowing vegetables from seedlings

• Eggplant – March
• Broccoli – February, March
• Broad beans – second half of February, first half of March
• Onions – February, March
• Pumpkin – May

• Kohlrabi – late February, March, June
• Tomatoes – March
• Leek – second half of January, February, March (late harvest)
• Spinach – 1st half of April
• Butter lettuce – March, early April

Some species of thermophilic vegetables in our climatic conditions can be grown only in this way. These include, for example: tomatoes, peppers, celery, cauliflower or cabbage.

Sowing dates for vegetables grown under covers

Growing under covers such as a greenhouse or hothouse not only allows you to grow vegetables that prefer warmer climates, but also allows you to extend the growing season growing season.

Sowing calendar for vegetables under cover
