Sowing and planting in September
Table of Contents
Often the vegetable patch empties slowly in September because the harvest is still taking place, but no new plants are being sown. But even in September you can still sow and plant wonderfully. Here you will find an overview of the various plants that can still easily migrate into the garden in September.
What can you plant in September?
Many don’t think September is the right time of year to plant new plants. But quite the opposite – for some plants, September is even the optimal time to be planted, because they benefit from the warm soil temperatures. Peonies ( Paeonia ) and irises ( Iris ) in particular should be planted in September because then they still have enough time to form enough new roots for the winter.
Steppe candles ( Eremurus ) also develop splendidly after being planted in September. Bulbs can also be planted in September: tulips ( Tulipa ), lilies ( Lilium ), and winter lumps ( Eranthis hyemalis ) are just some of the bulb plants that can be planted for the next spring. Wintergreen trees such as yew ( Taxus baccata ) or ivy ( Hedera helix ) can be planted particularly well in September.
Vegetables can also be grown in autumn. Cabbage varieties such as cauliflower ( Brassica oleracea var . Botrytis ) or pak choi ( Brassica rapa subsp. Chinensis ) can be preferred in the house and placed in the bed from September. Broccoli ( Brassica oleracea var. Italica ) and kale plants ( Brassica oleracea var. Sabellica ) can still be planted in September without any problems. If you like it a little more unusual, you can also plant Asian greenery in the snow ( Brassica juncea var. Mulitceps ) in September.
Late varieties of spinach ( Spinacia oleracea ) ensure crisp freshness in autumn. Even garlic ( Allium sativum ) is one of the plants that can still be planted in September. It is important to use local planting material that can cope with our climate. The garlic you can buy in most stores comes from warmer regions. Porcelain ( Claytonia perfoliata ) and parsley ( Petroselinum crispum ) can still be planted in September and overwinter in the bed before they can be harvested in spring.
What can you sow in September?
What else can you sow in September? A legitimate question, after all, from now on the days will be shorter and the falling temperatures will not make it easier for the plants to grow. Amazingly, there are still several plants that can cope well with the difficult conditions in September. Late savoy cabbage ( Brassica oleracea var. Sabauda ), cauliflower ( Brassica oleracea var . Botrytis ), or white cabbage ( Brassica oleracea var.
Capitata ) can be sown in the bed in September without any problems. Winter hedge onions ( Allium fistulosum ) and mustard ( Sinapis ) also thrive when sown in September. Fast-growing plants such as radishes ( Raphanus sativus var . Sativus ) or cut lettuce can be planted in the bed at the beginning of September and are ready for harvest at the onset of autumn.
If you don’t want to grow vegetables in September, you shouldn’t leave your beds empty: If you sow Phacelia ( Phacelia ), it not only reduces soil erosion but also serves as natural green manure in autumn. Winter vetch ( Vicia villosa ) or bitter lupins ( Lupinus angustifolius ) can also be sown as green manure in September without any problems.
In the ornamental garden, the time has come to sow biennial flowers such as the forest poppy (Meconopsis cambrica ) or forget-me-not ( Myosotis ) so that they can show their full splendor next year. Cold germs such as monkshood ( aconite ) or daylily ( Hemerocallis ) are also sown in September because they need the cold of winter to start growing in spring.

Harvest in September: which seasonal vegetables are ripe now?
The vegetable patch in September is often richly filled with various delicacies: Pumpkin ( Cucurbita ) is one of the classic seasonal vegetables in September, but turnips ( Brassica napobrassica ) and beetroot ( Beta vulgaris ) should not be missing in autumn. In addition, many types of cabbage are harvested in September, such as pointed cabbage, savoy cabbage, or Chinese cabbage. Also, crisp salad as Bativa (Lactuca sativa var. Longifolia) or oak leaf (Lactuca sativa var. Crispa) is still commonly harvested in September. If you like it a little hotter, you can look forward to fresh horseradish (Armoracia rusticana).
But those with a sweet tooth will also get their money’s worth because ripe apples ( Malus ), plums ( Prunus domestic ), and pears ( Pyrus ) hang on the fruit trees. Grapes ( Vitis ) also invite you to pick them, as do blackberries ( Rubus ) and blueberries ( Vaccinium myrtillus ), which are also in season in September. In addition, it is now time to harvest elderberries ( Sambucus ). With the aromatic sea buckthorn ( Hippophae rhamnoides ) you have to be careful in September that the berries do not turn over – if you pick them too late, they can develop a rancid aftertaste.

In fact, so many different shrubs, shrubs, and flowers bloom in September that it is not so easy to answer the question “What blooms in September?”. The classic flowers that still bloom in September definitely include aster ( Asteraceae ), coneflower ( Echinacea ), and sedum (Sedum). The autumn monkshood (Aconitum carmichaelii ) also blooms particularly expressively in September – but be careful: the plant is poisonous and should not be within the reach of small children.
Autumn anemones (Anemone hupehensis ) enchant with their impressive flowers in the flowerbed. A special eye-catcher in September has always been the sunflower ( Helianthus annuus ), which can be seen from afar. The saffron crocus (Crocus sativus ), from which the expensive saffron spice is extracted, is a pretty and delicate eye-catcher in the flower bed. In the woods, the thousand-flowered bush (Tetradium daniellii ) still shows its pretty flowers and attracts bees as if magically. In the herb garden, on the other hand, the mountain savory ( Satureja montana ) is in full bloom.

More work in the garden in September
Not only sowing and harvesting is part of gardening in September: the care of vegetables, the propagation of perennials, or fertilization should not be missing. We have compiled work that is still pending in the garden month of September for you here.
Fertilize vegetables: Celeriac still has a real growth spurt in September and needs to be supplied with nutrients accordingly. Tomatoes and peppers also benefit from final fertilization in September with a liquid vegetable fertilizer.
Put pumpkins up: Ripening pumpkins that lie on the ground often deform and are more prone to contamination and rot. To prevent this, it is a good idea to bed the pumpkins on straw so that they do not lie on the ground.
Attach glue rings: The flightless females of the frost moth (Operophtera brumata ) climb the trunks of fruit trees from October and lay their eggs. To prevent this, it is advisable to equip fruit trees with glue rings as early as September.
Cleaning the nest box: Many bird species not only use nest boxes to raise their young but are also used as a weatherproof shelter in winter. So that the nest box does not become a place of transmission of diseases, it is part of the gardening work in September to clean the nest box. To do this, old nesting material is removed and the dirt swept away. Chemical cleaning agents should not be used because they can have harmful effects on the new residents or put them off due to their smell.

Care for peppers and tomatoes: Tomatoes ( Solanum Lycopersicum ) and peppers ( Capsicum ) still produce new flowers in September. However, these should be removed regularly. In this way, the already existing fruits ripen better and can be harvested before the onset of winter.
Maintaining the lawn: Summer is often particularly stressful for the lawn – so the lawn needs an extra dose of care in autumn. With an autumn lawn fertilizer, you can not only strengthen the lawn but also prepare it perfectly for the coming winter.
Fertilize roses: So that roses ( pink ) survive the winter well, they should be given another low-chloride potassium fertilizer, in September. Among other things, this promotes the lignification of the shoots and thus ensures better frost resistance.
Harvesting seeds for the next year: The seeds of the runner bean (Phaseolus vulgaris ) can be collected and dried in September. Late September, when the pod loses its green color and becomes dry, is the perfect time to collect the beans for seed production. The seeds of annual plants such as sunflowers, marigolds, begonias, and Co. can also be obtained in September as seeds for the next year.
Dividing perennials: If you want to multiply your perennials or if a perennial in the bed has grown too big, you can divide it in September. To do this, the root ball is loosened from the earth and then divided with a spade. Then the perennials can be replanted in their new place.
Pruning perennials: Some perennials, for example, the maiden’s eye ( Coreopsis ) or the cockade flower (Gaillardia ), are so exhausted during flowering that pruning is inevitable if you want to enjoy them next year. A strong pruning close to the ground at the end of September, on the other hand, helps the plants to bloom in full beauty also in the next year.
Build winter quarters for hedgehogs: Hedgehogs are welcome to garden dwellers. If you want to support the hedgehogs in autumn with your garden, you can provide suitable winter quarters for the cute animals in September. A pile of dry leaves in a quiet corner is just as suitable for this as a special hedgehog house.
The golden October brings wonderful days every year to spend time in your own garden.
