Aloe Squarrosa Summary

Aloe Squarrosa Physical Characteristics

This is a short-stemmed, thin Aloe with branches forming from the base. The stem of a mature plant is 10-20 cm long and possibly 7-8 mm thick. Aloe Squarrosa’s leaves are curved backward and have beautiful white spots. These leaves have a rough surface because the white spots are superimposed above the surface.

However, there may be some plants in the species that don’t have the spots but have darker green leaves. Leaves are about 8 cm long and 2-3 cm wide at the base. Leaf margins usually have white triangular teeth.

It produces a 10-20 cm long raceme from which corolla red flowers grow. In detail, the flowers are cylindrical with a tapered base.

Aloe Squarrosa Care

This typical succulent requires just a little moisture in the substrate. The best watering method is soak and dry, only water the plant when moisture from the previous drink is depleted. However, when the plant is planted outdoors and well established, it only needs watering in instants of prolonged intense droughts.  

The soil in which you plant the succulent should be well drained to enable water to flow through easily. Water flowing through the pottage is necessary because it would otherwise lead to waterlogging.

Aloe Squarrosa requires little or no fertilizer, especially when planted outdoors. The natural habitat for aloes is relatively deficient in nutrients, so they are well adapted to such conditions.

Aloe Squarrosa Growth

It is possible to propagate this succulent using seeds, cuttings, and offsets. Seeds take quite a bit of time to mature into complete plants. The plant produces pups in large numbers, and they are pretty easy to grow, so they are the best option. Also, you can cut some of the stems and use them like seeds.

Aloe Squarrosa may need pruning to reduce congestion due to its branching stems. Also, they may need pruning once in a while to remove flower stalks and any extra leaves, especially the dry ones at the lower part of the plant. Besides, removing some offsets may be necessary to control its spread.

You need to repot it every time it doubles in size, thus outgrowing its pot. Also, you can re-pot your aloe if it needs a new substrate. It is vulnerable to pests such as spider mites and scales. The most common disease with this succulent is root rot.
