Why is my aloe plant turning yellow?

This is a fascinating aloe plant. Long leaves without or with thorns, as well as numerous tubercles, produce a distinctive look. Today, you can even find variants with red tubercles! Despite this, difficulties with this plant are common.

The major causes of aloe turning yellow include a lack of water, harsh sunlight, excessive watering, and poor fertilization. Water aloe whenever the soil in the pot is almost totally dry and fertilize your plant no more than two times a year to prevent discoloration. Also, make sure the aloe is in a somewhat shaded area that isn't too cold. Some of the explanations for why aloe plants turn yellow are listed below.

Overwatering

If aloe is over-watered, it is very likely to become yellow. Roots that are constantly wet start to decay. As a consequence, the leaves turn yellow as they progress up the blade from the base. The leaves get softer, and they may even become transparent.

To correct this, remove the aloe from the pot and thoroughly clean the roots of all soil. Next, look for rotting roots and remove them if necessary. Apply fungicide to the roots and let them dry for a few hours.

There is insufficient water

Yellowing of the aloe can also be caused by a lack of water. When the water supply that is in the leaves becomes depleted due to prolonged dryness, yellowing begins at the tips and progresses to the entire leaf. The leaves soften and begin to curl somewhat.
It is also possible that the aloe struggles from a shortage of nutrients in the lack of watering because it is fed by water. As a result, even if the plant still has an internal water supply, photosynthesis decreases. The aloe in this case turns a consistent yellow color.

Sunlight

Aloe leaves can become yellow if they are exposed to insufficient light. This plant requires 12 hours of the direct sunlight, however too much sun can cause difficulties.

Aloe Vera thrives in a south-facing window or even on a balcony in the majority of situations. In the summer, it is also customary for owners to bring this plant outside. In all of these circumstances, the aloe receives the right amount of light and appears to be in good health. However, if the weather is excessively hot and sunny, the leaves may become scorched. This is particularly true if you decide to grow it outside instead of inside.
To avoid this, gradually acclimate the plant to the novel amount of sunlight. Also, if the heat becomes unbearable, plant the aloe in a shady area. Return it to its original spot once the heat has subsided.

Conditions of growth

Aloe leaves can turn yellow due to changes in the growing environment. I'm primarily talking about temperature changes. The ideal temperature for aloe is 75-78 degrees Fahrenheit (24-26 degrees Celsius). This plant can also thrive in a range of temperature of 64°F to 73°F, however, it will grow more slowly.

The aloe will become stagnant and its leaves will turn pale when the ambient temperature lowers to 50-53 °F. The leaves, on the other hand, may turn yellow if the temperature changes dramatically. If the aloe is grown outside, sudden temperature swings are common. During the day, it can be hot, and at night, the temperature can drop considerably. To avoid this, only take the aloe outside if the weather forecast indicates that it is going to be warm at night.
