Drought-resistant roses can handle long stretches without rain far better than thirsty garden plants, but they are not made of stone. A tough rose may shrug off a dry spell once its roots settle in, yet even the most water-wise variety can struggle when the soil stays bone-dry for weeks and the weather keeps turning up the heat.
That makes the phrase “drought-resistant” a little misleading. It does not mean a rose can survive indefinitely without water, and it certainly does not mean a newly planted rose can go weeks on its own. The real secret lies in choosing a suitable variety, planting it well, building healthy soil, and watering deeply enough to encourage a strong root system instead of training the plant to expect a daily sip.
