Often grown outside in warm, arid regions, the Woolly Rose is best suited to U.S. Department of Agriculture plant hardiness zones 9b to 11; it should be brought inside during the winter if grown in colder climates.
Growing Conditions and General Care
Place the Woolly Rose where it will receive full morning sun or partially shaded afternoon sunlight. If the it is in a pot, place it out on the balcony or porch during warm, sunny weather. Give the Woolly Rose at least a foot (30 cm) of space on each side to prevent it from being crowded by other plants.
Water whenever the soil feels dry during the growing season. Water lightly until the soil is moist but not very wet. Woolly Rose can go for a long period without water once they are established, but they grow better and faster if they receive regular watering during the growing season.
Reduce watering during the winter, allowing the soil to dry thoroughly between waterings.
Fertilize Woolly Rose with liquid 2-7-7 succulent and cactus fertilizer during the growing season, from spring to late summer. Add seven drops of the fertilizer to 1 quart of water and sprinkle around the base of the succulent. Fertilize once every two weeks.
Woolly Rose will drop many of its lower leaves during the winter. Remove shriveled and fallen leaves as they accumulate around the base of the plant. Discard the leaves before they begin to rot. Decaying leaves can spread disease to the rest of the plant if not removed.
Repotting
Repot Woolly Rose plants once roots become visible around drainage holes. Repot into a pot 1 inch (2.5 cm) wider and deeper or out into the garden. Woolly Rose prefer very well-draining soil.
Propagation
Propagate Woolly Rose plants by taking cuttings during the growing season. Cut off a branch and allow it to dry for 24 hours in a warm location with indirect light. Plant the cutting in moist potting soil and place in indirect sunlight or where it will receive direct morning sun. Keep soil moist but not wet. Roots should appear within a few weeks after planting.
