How to water the roses
All plants, grown for ornamental purposes or not, need irrigations. L'watering of roses varies according to the period, weather conditions and climatic zone.
Generalizing it can be said that:
- In the growing season (from April to October), the roses must be watered every day.
- During the dormant period (from October to March), the roses must be watered every 15 days.
always water under tree avoiding wetting the leaves and flowers to avoid the onset of fungal diseases.
How to fertilize roses
Roses are very demanding and need repetitionsfertilizations. There are two or three fertilizations per year for those who grow roses in the open field, the first with the beginning of spring and the second around May / June. In the case of remontant roses in the open field, proceed with a third fertilization at the end of summer.
Those who grow roses in pots will have to fertilize monthly. While a granular fertilizer is more suitable for open field fertilization, for pot fertilization you can also intervene with a liquid fertilizer.
Fertilizers are important to support flowering and to prevent leaf tissues from turning yellow (yellow leaves are a symptom of nutrient deficiency in the soil).
The most suitable fertilizers for roses are those that provide:
- Nitrogen (N)
- Phosphorus (P)
- Potassium (K)
- Iron (Fe)
- Manganese (Mn)
Manganese, iron and potassium strongly support the flowering of roses while nitrogen and phosphorus support green tissues.
Among the fertilizers that provide, in a balanced way, the nutrients mentioned, we point out the granular fertilizer for rosesToprose. This fertilizer, to the listed nutrients, addsnatural activatorswhich increase the development of roots and buds. It can be used for both potted roses and open ground roses. On Amazon, this fertilizer is offered by Bayer at a price of 17.65 euros with free shipping costs.

At the beginning of March, remove any weeds, weed the soil superficially and distribute the granular fertilizer.
In the first half of June, preferably after a heavy rain, fertilize again with the slow release fertilizer. As stated, in the case of remontant roses, give the fertilizer again around September.
Theroses in vasethey have a small amount of substrate available. If you have recently done arepotting, you can also fertilize here with slow release fertilizer. If you have not done a repotting for a long time, it may be more appropriate to administer liquid fertilizer that allows a rapid absorption of nutrients by the plants.
The liquid fertilizer is very useful in case of yellow leaves of roses and to perform emergency interventions. Among the various products on the market, we recommend purchasing the One liquid fertilizer for its excellent composition. I personally use this fertilizer for many potted plants, especially roses and hibiscus. This fertilizer provides:
For all the information on the liquid fertilizer mentioned, we refer you to the page: Nutri One, the fertilizer is offered on Amazon at the price of 12.80 euros. It also contains zinc so it is also suitable for other ornamental plants such as amaryllis and hibiscus.
If in case of roses in vase it is possible to use liquid fertilizer and granular fertilizer, in the case of roses in the open field, we recommend the exclusive use of granular fertilizer and use liquid fertilizer only in an emergency.
How and when to prune roses
The period of pruningvaries based on the type of roses you are growing. Ancient roses (non-re-flowering) that bloom in midsummer should be pruned in late August-early September, while non-re-flowering climbing roses that bloom in late spring-early summer should be pruned in midsummer, at the end of flowering. Re-flowering roses should be pruned in late autumn, when they have stopped producing buds. For this topic, we refer you to the article "Pruning of roses“.

The winter it will be necessary to protect the roses from the cold. In late autumn, before the frosts, spread an 8-10 cm thick layer of mature manure at the foot of the rose bush (instead of mulch).
