On the (deviating) sowing dates
Just as the information on the seed packets and seed suppliers’ websites varies, so do the sowing calendars of seed suppliers and gardeners’ websites. Regional conditions are different everywhere and experiences vary. Our balconies in the cities have even more different conditions due to the heat of the city and radiating house walls. Here too, it is important to COURAGEOUSLY, PLAYFULLY and EXPERIMENTALLY gather your own experience and SEED. The seed itself ultimately decides after sowing whether the conditions of light, water and temperature appear favorable for germination or not until later.
Good information on sowing dates and conditions at:
- Bingenheim seeds, special page Current seeds in March — what can I sow now?
- Janet Glausch Natural garden seeds from Leipzig Special page — What can I sow now in March?

Potatoes can be pre-germinated for sowing. In warmer regions, they can be planted outside if the tender shoots are protected from frost with a cloche or fleece.

Planting and caring for fruit trees and shrubs
New shrubs can be planted during the dormant period until they sprout (early February to mid-May), container plants all year round. Aronia berry, rock pear, cornelian cherry and cherry are particularly suitable for use in containers. Columnar apple trees Proven. The best way to buy fruit trees is bare root from a professional fruit nursery. They can advise you on the variety that is suitable for your climate and cultivation in large containers. Variety and rootstock/rootstock (slow-growing) make a big difference to success. Our experts Conrad Amber and Dr. Sonja Schwingesbauer presented ourselves for the 6th Online Organic Balcony Congress March 2021 Can you plant animals? lists of which woody plants are suitable for the extreme balcony location. In September 2024, the Organic Balcony Congress was dedicated to Shrubs in tubs. A List with 105 woody plantswhich have proven themselves in pot cultivation.
Strawberries planted now as an underplanting will not bear abundantly in the first year, but will do so the following year. Monthly strawberries or continuously bearing strawberries are great (Mara des Bois). The existing soft fruit with Worm humus or compost or mulch with horn shavings or Sheep’s wool pellets fertilize as a slow-release fertilizer.
Here is a good source for bare-rooted shrubs in Demeter quality, es kann nie genug Beeren geben.

Harvest in March
As the days get warmer and longer, you will notice that the plants start to make a growth spurt. They can be harvested towards the end of the month: In addition to leafy vegetables such as Swiss chard, kale, spoon cabbage, winter cress, chopped garlic, chopped celery and Asian salads, the frost-hardy culinary herbs rosemary and sage can also be harvested. If you have planted Jerusalem artichokes, you can dig them up now and leave a tuber in the pot for the next season. From our native wild plants sorrel, mugwort, Dandelion, goutweed and nettles young shoot tips can be harvested.

Keep your feet still, don’t cut anything down
As is the case throughout the fall and winter, leave dead stems standing because they are important habitats for insects. So keep your feet still and look forward to the season! People used to clean all their pots at this time of year. But that’s not necessary, it was probably mainly to keep gardeners busy in winter.

Winter protection — tidying up?
To protect our insects, wait with the tidying up, with the pruning, delay it, they still need their winter quarters. Please leave it “untidy”, even if the sun is shining beautifully and the early bloomers are already peeking out and starting to blossom. It is often still too early to cut them back. The fresh green of the perennials can be clearly seen. Store the cut stems and foliage as loosely and airily as possible in a SUNNY PLACE for about 5 days so that the insects can crawl out. Here, biologist Elke Schwarzer talks about overwintering guests and when to prune.
