One of the fundamental rules in the irrigation of roses is to supply water regularly, so that there are no sudden changes between drought and excessive water intake. In the summer and spring, watering must be more abundant, but be careful not to overdo it because even the rose fears water stagnation. It should be borne in mind that generally we tend to irrigate too much and too often, while experiments have shown that roses have a root system that goes deep, looks for water and roses do not have a particular water need. Conversely, too much water increases the chances of fungal attacks. During the hottest seasons, spring and summer, the best phases of the day to water the roses will be in the morning and in the evening respectively; in these periods with very high temperatures the roses will be watered every week very abundantly and very deeply. In any case, keep in mind that water will be provided at the base of the plant. In the case of cultivation in pots, however, regarding the amount of water needed, during the summer you can water the roses even twice a day, while in the other periods a little less, in the winter very little. As a general rule, keep in mind that the water needs of roses vary in relation to the climatic trend: normally for a medium-sized rose shrub 12-15 liters of water are enough once every three days, while when the temperature rises, it is necessary to reduce the interval between one administration and another.
