Answer: Watering a desert rose can be a bit confusing. Desert rose will thrive under conditions of copious rainfall during hot periods of the year (temperatures above 80F), provided they are growing in a perfectly free draining soil on a site that does not flood. During the cooler months of the year however, desert rose is far more prone to root rots, and the soil should be allowed to dry out between waterings. Water should be completely withheld if day-time temperatures fall below 80F, or the weather is cool cloudy. In Texas desert rose can be grown outdoors year round, with regular watering restricted to those times of the year when there is an extended period of hot, dry weather, as sometimes occurs in late spring.
