Rose bushes are the true stars of our gardens, and their beauty is matched only by their intoxicating scent. But as fall approaches, these beautiful plants require special attention to continue to flourish. Here are 6 tips for taking care of your rose bushes in September and ensuring sumptuous flowering throughout the season.
Lightweight and efficient size
In September, it is recommended to carry out light pruning on your rose bushes to encourage new flowering. Cut stems that have already flowered with sharp, disinfected shears to prevent the spread of disease. Be careful though, certain varieties of rose bushes do not benefit from autumn pruning, especially those which only flower once per season. In regions with a harsher climate, it is better to wait until spring to prune your rose bushes.
Nutrition and natural fertilizers
For continuous and vigorous flowering, rose bushes need essential nutrients. Apply a natural fertilizer rich in potassium and phosphorus, such as roasted horn, in September to strengthen your rose bushes against the rigors of winter. Avoid excessively nitrogenous fertilizers which would promote excessive growth of shoots and make them more susceptible to diseases and frosts.
Regular and appropriate watering
Watering is crucial to keeping your rose bushes healthy. In September, adapt watering according to climatic conditions and the nature of the soil. Be sure to water enough so that the roots receive the necessary water, but not too much, to prevent the risk of rot and diseases due to humidity.
- In case of strong heat, water approximately every two days,
- If the weather is cooler, one watering per week may be sufficient,
- Potted roses require more frequent watering.
Preventive treatment against diseases
In order to protect your roses from diseases such as powdery mildew, rust or scab, carry out a preventive treatment from the beginning of September. Opt for natural solutions such as a decoction of garlic or horsetail, which will also have the effect of strengthening the plant’s resistance to external aggressions.
Mulching to retain moisture and heat
Mulching is a simple and effective gesture to help your rose bushes flourish in autumn. This helps to conserve soil moisture, maintain a constant temperature at root level and limit the proliferation of weeds. Use an organic mulch, such as wood chips or pine bark, which will gradually break down to nourish the soil and enrich its structure.
Select the right rose bushes for your garden
To take full advantage of your roses in September and until autumn, choose remontant varieties, that is to say, capable of flowering several times during the season. Among these roses, we find hybrid teas, polyanthas, floribundas and certain climbers. Also be sure to install your rose bushes in a location well exposed to the sun and protected from cold winds.
By following these tips, you will be able to take full advantage of the beauty and fragrance of your roses throughout the fall, and offer them the best possible conditions to face the coming winter.
