More work in the garden in September
Not only sowing and harvesting are part of gardening in September: caring for vegetables, propagating perennials or fertilizing are also essential. We have compiled work for you that is still pending in the garden month of September.
Fertilize vegetables: Celeriac still has a real growth spurt in September and needs to be supplied with nutrients accordingly. Tomatoes and peppers also benefit in September from a final fertilization with a liquid vegetable fertilizer such as Plantura Organic Tomato & Vegetable Fertilizer.
Put Pumpkins Up: Ripening Pumpkins lying on the ground often deform and are more susceptible to contamination and rot. To prevent this, it is a good idea to lay the pumpkins on straw so that they do not lie on the ground.
Attach glue rings: Flightless females of the winter moth (Operophtera brumata) climb up 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: Nest boxes are not only used by many bird species to raise their young, they are also used as a weatherproof shelter in winter. So that the nest box does not become a place of transmission of diseases, gardening work in September includes cleaning the nest box. Old nesting material is removed and the dirt swept out. Chemical cleaning products should not be used as they can have harmful effects on the new residents or put them off with their smell.
Care for peppers and tomatoes: Also in September, tomatoes (Solanum lycopersicum) and peppers (Capsicum ) still new flowers. However, these should be removed regularly. In this way, the fruits that are already there ripen better and can be harvested before the onset of winter.
Care for the lawn: Summer is often particularly hard on the lawn - in autumn the lawn therefore needs an extra portion of care. With an autumn lawn fertilizer, for example the Plantura autumn lawn fertilizer, you can not only strengthen the lawn, but also prepare it perfectly for the coming winter.
Fertilize roses: In order for roses (Rosa) to survive the winter well, they should be fertilized again in September with a low-chloride potassium fertilizer, such as our Plantura organic rose fertilizer. Among other things, this promotes the lignification of the shoots and thus ensures better frost hardiness.
Harvesting seeds for next year: The seeds of the runner bean (Phaseolus vulgaris) can be collected and dried in September. At the end of September, when the sleeve is theirlosing green color and drying out is the perfect time to collect the beans for seed. The seeds of annual plants such as sunflowers, marigolds, begonias and Co. can also be obtained in September as seeds for the following year.
Dividing perennials: If you want to multiply your perennials or if a perennial in the bed has become 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. The perennials can then be planted again in their new place.
Pruning Perennials: Some perennials, such as the Queen's Eye (Coreopsis) or the Blanket Flower (Gaillardia ), wear themselves out so much during flowering that pruning is unavoidable if you want to continue enjoying them next year. On the other hand, vigorous pruning close to the ground at the end of September will help the plants bloom in all their glory next year.
Build winter quarters for hedgehogs: Hedgehogs are welcome garden dwellers. If you want to support the hedgehogs in autumn with your garden, you can provide a suitable winter quarters for the cute animals in September. A heap of dry leaves in a quiet corner works just as well as a special hedgehog house.
