Reason Behind Aloe Plant's Brown Discoloration

Aloe vera plants, classic indoor succulents, are native to southern to eastern Africa and have become popular for their easy-to-maintain nature. However, to ensure their health and growth, it's essential to provide them with the right conditions.

Firstly, aloe vera plants require soil that is slightly porous and freely draining. Overwatering can encourage fungal disease and certain pests, while lack of drainage can lead to root rot, a fungal pathogen that causes a brown aloe vera. Mixing in 40% pumice or sand to the soil can increase percolation and provide extra drainage.

In terms of watering, aloe vera plants prefer a wet-dry cycle. They should be fully saturated and then allowed to completely dry out. During the winter, watering should be reduced to half the amount compared to summer and spring.

Light is another crucial factor. Indoor aloe plants should be placed at a window where they receive at least 6 hours of sun daily. Too much sun can cause the leaf tips of aloe vera plants to burn, while lack of light will force the plant to stretch and elongate, affecting its colour and the characteristic markings.

Temperature is also important. Aloe vera plants require warm temperatures, with daytime temperatures between 70-80 degrees Fahrenheit (21-27 C) and night-time temperatures at 50 degrees Fahrenheit (10 C). Southern windows during the hottest part of the day have the potential to damage the waxy cuticle and leaf tissue of aloe vera plants.

Outdoor aloe plants should be protected if a cold snap is expected, as they do not like a sustained freeze. A leggy aloe vera may flop over due to top-heavy growth, so it's advisable to position them a bit away from a drafty door or window to avoid leaf tip discoloration due to cold drafts.

Artificial lighting, such as a white fluorescent light set 12 inches away from the plant, can help ensure enough light for aloe vera plants if natural light is lacking.
