Mustard is a very undemanding crop and not only thrives in the garden bed but also in pots on the windowsill or on the balcony. Below you will find out what to consider when sowing.

Which seed is the right one?
In general, brown, black and white (yellow) seeds are distinguished. The three differ not only in taste but also in their height. Black mustard is the tallest with a growth height of up to 1.80 m and is therefore particularly suitable for cultivation in the garden. White mustard, on the other hand, only grows to a height of 30 to 70cm and can therefore also be grown well on the balcony.
Where can mustard be sown?
As already mentioned, mustard does not only thrive in the garden bed. Simply sow your mustard in a pot on the balcony or even in a bowl by the window. It is important that it gets some light so that it can grow properly and that you keep the substrate moist.
When is mustard sown?
In principle, mustard can be sown all year round. However, like all young plants, young mustard is sensitive to frost and should therefore only be planted outdoors after the ice saints. If you want to harvest the seeds, a sowing date in May is advisable. The mustard flowers in summer and you can harvest the mustard seeds in autumn.
How to sow your mustard
You can either sow your mustard directly outdoors in May or you prefer it on the windowsill and transplant it outside after the ice saints. How to proceed with sowing:
- Loosen up the soil in the garden bed or fill your seed trays with soil.
- Moisten the potting soil or the soil in the garden bed.
- Put the mustard seeds on the ground.
- Keep a planting distance of 15 to 20 cm (depending on the variety).
- Cover the seeds with a layer of soil about 2cm thick.
- Moisten the soil.
If you have a lot of birds in your garden or on your balcony, it is advisable to protect the seeds with a net or scarecrow. To be on the safe side, you can sow the seeds more densely and prick them out as soon as the seedlings have two pairs of leaves.
What comes after sowing?
Mustard requires little care. Make sure, however, that the substrate does not dry out, especially immediately after sowing. Mustard germinates relatively quickly, so that young mustard plants can be seen after just a few days.
