Aloe Vera is a drought-resistant plant and thrives with less water. The succulent waxy leaves stores water and prevent moisture loss by vaporization. These evergreen perennials have long green to light green leaves with serrated edges placed in rosette around the stem base.

Watering Aloe sometimes can be tricky because overwatering can kill the plant. Check the moisture in the soil, when soil is dry then water aloe plants on the edges. Watering the center will harm plant growth causing root to rot.

In the case of indoor-grown plant, water aloe plant as needed but the soil should always be well-drained and dry. Remove water from plant saucer and leave it dry. Excess watering of aloe plant both indoors or outdoors will cause the plant root to rot and die.

During winter and rainy season – no watering or minimal watering is required.

2.How much sunlight is needed?

Aloe Vera is best known to thrive well in dry conditions. Sunlight of 7-8 hours per day is best for the plant, but they do well as indoor plant too.

Place them in the south or south-west regions of the house, so that plant is not deprived of sunlight. Aloe plants indoors generally grow very tall and lanky when deprived of sunlight.

In case when rooms don’t have access to enough sunlight, these plants need artificial lights. These are tropical plants; Aloe Vera loves temperature between 150c to 250c. They do not tolerate snow and frost conditions. When Aloe is growing outdoors, it is good idea to move them indoors in winter months.

3. What type of soil does Aloe Plant need?

Well-drained cacti or succulent soil is best for Aloe Vera. But they grow well in potting soil/garden soil mixed with some sand. This is less expensive and easiest way to grow Aloe Vera.

The soil should be ultimately well drained and aerated. Poor soil drainage will cause water to stagnate and cause root rotting and prevent absorption of nutrients by the plant. Take care to mix some sand or perlite or gravel in the potting soil for proper drainage.

4.What type of container or pots can Aloe grow?

Aloe Vera has a root system which is very shallow and not deep. Their roots spread out horizontally and few inches below ground. Best choice for a pot will be a wider one not very deep about a size of 2’’ to 12’’ in size.

When grown as indoor plants using organic compost or fertilizer is a good option as other chemical fertilizer can pollute indoor air or leaves may be ingested by pets. Fertilizing aloe plants can be done twice in a year.

Repotting needs a bigger, porous pots or containers with drainage holes. Terracotta pots are preferred over plastic ones as they are porous and biodegradable. Repotting is usually done when plants outgrow, and roots cannot spread out. The plant struggles to grow further, then plant is transferred to bigger pot with potting soil mixed with sand and gravel.

Repotted plants are not watered immediately but can be kept in sunlight. Watering repotted plants can be done in a week or when new roots begin to grow. Care should be taken not to overwater the plants and water from plant saucer removed.

What diseases and pests affect Aloe?

Diseased Aloe Vera leaves turn brown and wilt away. There are 5 reasons which causes browning in these immortal plants

  1. Excess Light

When Aloe plants receives less sunlight or too much of sun, they turn brown. Aloe Vera needs plenty of sunlight when outdoors, but when grown indoors they are to be placed in south west directions.

They always need a warm partial light. When indoor grown plants are moved outdoors for sunlight they must left in partial sunlight for a week before moving into full or direct sunlight.

Sudden exposure to sun can cause sunburn or shock in plants. This will turn leaves of aloe plant leaves to turn brown.

2.Excess Watering

Watering Aloe Vera is a very critical step in growing Aloe Vera. When aloe plant leaves develop brown spot, it is due to excess watering. Excess watering causes roots to rot, fungal stem rot and leaves to rot.

In case of excessive watering, do not water plants till the soil dries up. In winter watering is done less frequently, maybe once in four weeks. If the plant looks very dry, wilted and leaves curl up because of water deprivation, then water aloe plants as needed.

Optimal time of watering – For outdoor Aloe Vera watering is done once in two weeks and indoor grown watering is done once in three weeks.

3. Temperature

Ideal temperature for Aloe Vera would be 180c to 280c. It cannot withstand temperature dips, frost and snow. In winter months it would be better to move Aloe plants indoors.

The extreme temperature will turn plant leaf brown and begin to wilt. Too much hot and bright sunlight can also kill Aloe Vera by causing sunburns.


Soil for Aloe Vera must be a well-drained soil, with no water stagnation and easy for roots to penetrate and absorb nutrients. These succulents need cacti soil or 3/4th potting soil mixed with 1/4th sand or perlite and gravel. Poor draining soil will cause roots to rot and ultimately leaves turn brown and wilts.


Sometimes Aloe Vera plants turn brown because of over-fertilizing. It can be fertilized once in winter and spring or twice in a year. Excess amount of salt or any nutrients will kill or burn the roots causing leaf browning and wilting.


Aloe Vera when not properly cared will be affected by pests like aphids and mealybugs. They cause leaves to turn sticky because of honey mildew left by the pests on feeding the sap of aloe plants.

The only treatment would be washing the entire plant in warm water or spraying water mixed with organic soap and neem oil. Chemical insecticide cannot be used on indoor-grown ones and ones that are used for medicinal purposes.

How to revive a dying Aloe Vera plant?

The solution to plant rotting will be to repot or replant affected aloe plants in a new container. The affected plant is removed of the old pot with roots intact and mushy rotted roots cut away with scissors.

A new pot of size 1/3rd more than the plant is taken and filled with well-drained soil mix. The plant is now replanted in new pot and left in sunlight. Watering should be done after a week or when new roots are established in the soil.

How long does the plant live?

Aloe Vera has a longevity of 5 to 25 years. A well cared aloe plants can live many decades. A small aloe plant mostly takes 4 years to grow mature leaves of size 10 inches. They have pretty longer longevity when compared to other house plants. There are wild species of Aloe Vera which can live up to 100 years and name ‘immortal aloe’ is the perfect name for these amazing succulents.

How to Grow and Propagate Aloe Vera Plants?

Repotting from Aloe Vera pups or baby Aloe plants is the most common method of propagation. This type of propagation method from aloe pups is also called division. Growing a new plant from just leaf cutting is not a popular method because of too much moisture in leaves.

Because, leaf cuttings do not develop roots and will end up in dried and wilted leaves. A well grown Aloe plant will produce small offsets or plant offshoots or aloe pups growing around the parent plant base.

Take care to remove the pups from parent plant with some roots intact. These Aloe pups share the root system with parent plant, so wait till aloe pups have 3 to 4 leaves of their own, big enough to survive and develop their own roots.

Usually, aloe pups should be 1/5th size of parent plant. Aloe pups are repotted in well-drained soil and wait for one week to water repotted plants.
