Sowing Calendar: What to Sow and Plant When

Knowing the right time for sowing and planting is half the battle in the vegetable garden.

February/March – Pre-cultivation begins

Peppers and chili need the longest lead time → sow on the windowsill from early February.

In March follow: tomatoes, celery, leeks, lettuce for the early harvest.

These plants cannot tolerate frost and only go outdoors after the Ice Saints (May 12–15).

March/April – Cold-tolerant direct sowing

From mid-March, sow directly outdoors as soon as the soil is workable:

• Carrots, spinach, radishes
• Peas and lamb's lettuce
• Parsley and dill

May – Main planting

From late April / early May (soil temperature above 10 °C):

• Sow beans and zucchini directly
• Plant or sow cucumbers and squash
• Plant out pre-grown tomatoes, peppers and basil after the Ice Saints

July/August – Second season

Now sow for autumn and winter:

• Plant kale (Brussels sprouts are planted back in May/June – they need the long growing season)
• Sow Asian salads, winter purslane, lamb's lettuce directly
• Plant garlic from October for next year
