Grow from seeds, sown in well-drained soil in a seedling tray, in spring or summer. Or lift and divide clumps and remove the small plants from the mother plant (offsets), in late spring.

Aloe grandidentata is easy to grow and does well in gardens. Grow them in well-drained, sandy soil, in an open, sunny to semi-shaded position. Water moderately to sparingly in summer. They will thrive in hot, dry conditions and should withstand moderate frost and are well-suited to water-wise gardens, rockeries and containers. Plants sucker freely and clumps expand to form large groups.

Common problems with aloes are overwatering or growing them in wet conditions, which can lead to rotting; they are also prone to sapsucking insects, which are often found beneath the leaves near the base of the plant, as well as pests such as aphids, mealybug and white aloe scale and fungal diseases, such as leaf spot and root rot.
