Staying in the garden in September is once again pleasant: temperatures are beginning to drop, especially at night and in the morning. Rainfall then becomes more frequent, reducing the frequency of irrigation. The climatic conditions stimulate the vegetative recovery and, in the predisposed plants, a new flowering. Many gardeners say that September is “a second spring”, perhaps even more pleasant. The inflorescences, less abundant, are, however, more lasting and the colours more delicate.
Furthermore, in the last decade, the colour of the leaves begins to turn towards warm tones, rendering the atmosphere unique.
Seeds and divisions
The temperatures, which are still quite high but not scorching, are ideal for dividing up, sowing and planting grasses in particular.
To be successful in the divisions we recommend working quickly in the evening: we extract the head from the ground and divide with forks or pitchforks. We reinsert again, then irrigate in abundance. Plants that are worked in this way have all night to recover and all winter to root. In spring they will be ready to give their best again.
Sowing is just as successful. It is the ideal time especially for perennials and biennials: the wet weather promotes germination; temperatures are high enough, but not so much as to weaken the young subjects. In spring they will, in many cases, be ready for strong vegetative growth and also for flowering.
- September is one of the golden months for the garden, orchard and vegetable garden. By working hard during these weeks, we can lay a solid foundation for the optimal development of our plants during the spring…
- Routine maintenance must be carried out both on healthy meadows and on meadows that have suffered some damage. First of all, we will have to clean up the surface of the residues left by the torrid period. At this point, we will have to…
With the fall in temperatures and the increase in rainfall, the growth of weeds is resuming. They steal resources and light from ornamental plants, as well as being a vehicle for diseases and parasites (to be controlled with special pesticides).
Horticultural plants with very long stems (aster and dahlias…) are in the process of blossoming and can be bent by heavy rainfall.
Let’s prune the hedges and clean up the shrubs that have definitively finished flowering.
The work of cleaning the wilted inflorescences also continues: removing them regularly can stimulate, in cases of predisposition, a new production. It is also an ideal time to dry some (lavender, echinops, eryngium, elicriso, statice, gypsophila) and collect the seeds for future years.
Manual irrigation may still be necessary, especially at the beginning of the month.
New plants and cuttings
In September, in Italy, it is usually still too hot to plant bare-root shrubs, especially in the first two decades: however, it is not risky for those with bread of earth, provided they are abundant with irrigation.
From the middle of the month, especially in the northern regions, it is possible to start planting the bulbs that bloom in winter and early spring: snowdrops, crocuses, cyclamen, fritillaries, narcissi).
September is ideal for making woody and semi-woody cuttings of shrubs and creepers: we use a very light and moist compost, covering with plastic cap. A shady but bright position will favour rooting. In the spring, the vegetative development will already start.
The garden in September: For the lawn
In this period the lawn requires a lot of effort: it will have to resume growth after the stalemate due to the high temperatures of August. To have a homogeneous and bright green coat again, we recommend cleaning the felt (even with a rake with thick mesh) and make a passage with the spiked shoes (it will facilitate the penetration of water). Finally, let’s distribute a good complete fertilizer and water abundantly, possibly early in the morning.
Towards the end of the month the leaves of trees and shrubs will begin to fall: let’s work to remove them quickly so that they do not encourage the settlement of cryptogams.
We cut the lawn regularly (at least twice a week), lowering the height a bit compared to the summer months.
