Aloe Marlothii Summary

Aloe Marlothii Physical Characteristics

It has a relatively long stem and large grey-green leaves. The leaves have spines on the margins, and a few may appear on random parts of the leaf. The spines are reddish brown. These leaves form a dense rosette towards the end of the stem. The rosette itself is considerably large owing to the bulk of the leaves. One leaf can be as long as five feet. The leaves are lanceolate and recurved. Older leaves on the lower part of the rosette dry and droop, forming a skirt or a ‘petticoat’ around the stem, one of this plant’s distinct characteristics.

It blooms in the fall and winter by producing branching racemes from which its tubular flowers grow. Flower color can vary from orange-red to yellow.

Aloe Marlothii Plant Care

This vigorous, relatively big one is best used for xeriscaping and Mediterranean gardens. You can grow it in a container for the first few years, but it will eventually need space. It requires just a little moisture in the substrate. The best watering method is soak and dry. However, when the plant is planted outdoors and well established, it rarely needs watering.

The soil on 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.

It 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.

DO YOU KNOW? Caring (propagating, pruning/trimming, beheading, watering, …) is a set of skills that is widely applicable to succulents. Read the in-depth guide here >>

Aloe Marlothii Growth

It is possible to propagate this succulent using seeds or stem cuttings. Seeds take quite a bit of time to mature into full plants. You can obtain cuttings from an old plant’s stem. They grow faster than seeds and may be the best option for this aloe since it doesn’t offset.

Pruning this aloe needs to remove some dry leaves on the lower side of the rosette, i.e the skirt. Also, you might cut back some leaves to keep the plant from overgrowing if you are constrained for space. When young, you must repot it occasionally and eventually transfer it to a garden for the best effects. It is virtually pest-resistant but may be attacked by mealybugs, spider mites, and scales. Avoid waterlogging to keep root rot at bay; you are virtually safe from diseases.
