Aloe vera is one of the most popular houseplants due to its ease of care, medicinal properties, and visual appeal However, many plant owners struggle to determine the right watering schedule for their aloe vera. Understanding the water requirements of this succulent plant is key to keeping it healthy and thriving indoors. This comprehensive guide will provide you with everything you need to know about watering your aloe vera plant.
How Often Should You Water Aloe Vera?
Aloe vera is native to arid regions and thrives in dry conditions. As a succulent it stores water in its thick, fleshy leaves. This means that it does not need frequent watering. Overwatering is the most common cause of problems in aloe vera plants. It can lead to root rot fungus gnats, and leaf spot diseases.
As a general rule, you should water your aloe vera plant deeply once every 1-2 weeks in the spring and summer. In the fall and winter months, you can reduce watering to once every 3-4 weeks. The soil should be allowed to completely dry out between waterings.
Check the soil moisture by inserting your finger into the potting mix. If the top inch feels dry, it’s time to water. You can also look for visual cues from the plant like wrinkled, thinning leaves which indicate underwatering.
How Much Water Does an Aloe Vera Plant Need?
When watering your aloe vera, pour enough water so that it drains freely from the bottom of the pot. This ensures the entire root zone is hydrated.
The exact amount will depend on factors like pot size, plant size, temperature and humidity. Aim to water until the top 50% of the soil is moist. Don’t leave your plant sitting in water.
Small, young plants in 4 inch pots may only need 1/4 cup of water each time. Larger, mature plants in 8-12 inch pots can take 1-2 cups of water at a time. Outdoor aloe vera plants need more frequent watering to compensate for sun and wind exposure.
What Type of Water is Best for Aloe Vera?
Aloe vera prefers soft, pure water instead of hard tap water which contains minerals that can build up in the soil. Filtered, distilled or rainwater are the best choices. If using tap water, allow it to sit out overnight before applying so the chlorine can dissipate.
The water should be at room temperature. Cold water straight from the tap can shock the plant’s roots. Avoid fertilizing during the winter when growth has slowed.
Watering Methods for Aloe Vera
You can water aloe vera from the top or bottom. Top watering is the traditional method where you pour water directly onto the soil surface. With bottom watering, you fill a container with water and set the pot in it to absorb moisture from below.
Bottom watering ensures the soil is thoroughly saturated. It also prevents water from getting on the leaves which can lead to bacterial and fungal diseases. Let the pot sit for 20-30 minutes until the top of the soil is damp.
An occasional top watering can help flush out built up mineral salts from fertilizer. Just avoid getting the rosette and leaves wet.
Signs Your Aloe Vera Needs Water
-
Soil is dry 1 inch below the surface
-
Pot feels light when lifted
-
Leaves appear thin, wrinkled or shriveled
-
Leaf tips turn brown
-
Slow growth
-
Dull, faded color
-
Leaves drooping or curling inward
These visible cues indicate your aloe would benefit from a deep watering to rehydrate. Catching underwatering early prevents permanent damage to the plant.
Overwatering Aloe Vera
While aloe vera doesn’t need much water, it’s still possible to overdo it. Excess moisture deprives roots of oxygen, encouraging harmful bacteria and fungi. Symptoms of an overwatered aloe include:
-
Mushy, translucent leaves
-
Yellow, drooping lower leaves
-
Soft, rotten roots
-
Mold growth on soil
-
Foul odor from the pot
If you suspect overwatering, take action immediately. Remove the plant from the wet soil and discard any rotten roots. Repot in fresh, dry soil and do not water for 1-2 weeks to allow it to recover.
Tips to Prevent Overwatering
-
Use containers with bottom drainage holes
-
Amend soil with perlite or gravel to improve drainage
-
Water only when top inch of soil is dry
-
Pour off any water in saucer after 30 minutes
-
Allow more time between waterings in cool weather
-
Keep plant on the dry side in humid environments
-
Feel soil to gauge moisture rather than on a fixed schedule
Outdoor Aloe Vera Water Requirements
If growing aloe vera outdoors, it will need more frequent watering during hot, dry weather. Aim to water 1-2 times per week if temperatures exceed 85°F and there is no rain. Container plants may need daily watering in extreme summer heat.
Established in-ground aloe vera can survive on rainfall alone in humid climates. But supplemental water maintains faster growth and more abundant blooms. Even drought tolerant aloe vera benefits from occasional deep soaking.
Watering Aloe Vera in Winter
Scale back on watering aloe vera in the winter when growth naturally slows. Cooler temperatures and shorter daylight hours signal the plant to go dormant.
Only water every 3-4 weeks in winter. The specific timing depends on factors like your climate, pot size, and whether it’s indoors or outdoors. Do the finger test to be sure the soil is completely dry before the next watering.
If your plant is looking shriveled, go ahead and give it a drink. Aloe vera stores water in its leaves so underwatering causes visible wrinkling. But it’s better to err on the side of less water in winter.
Choosing the Right Pot for Aloe Vera
Well-draining soil and containers are vital for preventing wet feet in aloe vera. Plastic pots are lightweight and affordable but retain moisture. For better drainage, choose unglazed terracotta or ceramic pots which allow evaporation through the porous walls.
Make sure containers have drainage holes to prevent waterlogging. Put a layer of gravel or pebbles at the bottom to improve drainage. A quality cactus mix amended with perlite provides the fast drainage aloe vera needs.
Match the pot size to the plant, only moving up 1-2 inches at a time. Underpotting encourages faster growth while overpotted plants sit in wet soil.
Common Mistakes in Watering Aloe Vera
Many issues with aloe vera can be traced back to improper watering. Here are some common watering mistakes:
- Insufficient draining leading to soggy soil
- Watering on a strict calendar schedule
- Not adjusting for seasonal changes
- Allowing water to sit in saucer
- Large pot holding too much moisture
- Tap water containing excess minerals
- Pouring cold water directly from the tap
- Getting water on the leaves
- Mistaking drought stress for need to water
Learning from these errors will help you avoid over and under-watering. Pay close attention to your plant’s needs and adapt your schedule as needed.
When to Water Aloe Vera
The ideal time to water aloe vera is in the morning before the sun gets too intense. This gives the water a chance to permeate deep into the soil before hot afternoon temperatures speed up evaporation.
Avoid watering at night since wet foliage overnight can encourage disease. Afternoon watering is fine too as long as the plant has time to dry out before evening.
Only water when the soil is completely dry to avoid moisture buildup. Determine this by feeling with your finger or lifting the pot to gauge weight. Get in the habit of inspecting soil and plant condition frequently so you can respond appropriately.
FAQs About Watering Aloe Vera
-
How do I know when my aloe vera needs water? Check the soil moisture by inserting your finger into the pot. If dry 1-2 inches down, it’s time to water. Signs of underwatering like wrinkled leaves are also indicators.
-
What kind of water should I use on aloe vera? Filtered, distilled or rain water are best. Tap water can be used if allowed to dechlorinate before applying. Avoid hard water high in minerals that can burn the tender roots.
-
Can aloe vera be overwatered easily? Yes, aloe vera is very susceptible to overwatering since it naturally grows in arid conditions. Ensure the soil drains well and don’t water again until the top inch is completely dry.
-
Should I mist my aloe vera plant? No, misting is not recommended as the succulent leaves can easily rot if they remain damp for prolonged periods. Occasional humidity is beneficial though.
-
Can I grow aloe vera in water alone? No, aloe vera plants
Growing Aloe Vera Plants: Watering, Lighting, Repotting, Use, and More!
Learn all about aloe vera plant care—from how to care for aloe vera to how to grow this succulent outdoors and indoors in your home. Aloe vera is so rewarding! The juice from their leaves has medicinal purposes and can be used to relieve pain from scrapes and burns. See our Aloe Vera Plant Guide.
Aloe vera is a succulent plant species of the genus Aloe. The plant is stemless or short-stemmed with thick, greenish, fleshy leaves that fan out from the plant’s central stem. The margin of the leaf is serrated with small teeth.
Before you buy an aloe, note that you’ll need a location that offers bright, indirect sunlight (or artificial sunlight). Direct sunlight can dry out the plant too much and turn its fleshy leaves yellow, so you may need to water more often if your aloe lives in an exceedingly sunny spot.
Keep the aloe vera plant in a pot near a kitchen window for periodic use.
WARNING: The gel from aloe vera leaves can be used topically but should NOT be eaten by people or pets. It can cause unpleasant symptoms such as nausea or indigestion and may even be toxic in larger quantities. Read Next
How to Care for an Aloe Vera Plant
- Lighting: Place in bright, indirect sunlight or artificial light. A western or southern window is ideal. Aloe that are kept in low light often grow leggy.
- Temperature: Aloe vera does best in temperatures between 55 and 80°F (13 and 27°C). The temperatures of most homes and apartments are ideal. From May to September, you can bring your plant outdoors without any problems, but do bring it back inside in the evening if nights are cold.
- Fertilizing: Fertilize sparingly (no more than once a month), and only in the spring and summer, with a balanced houseplant formula mixed at 1/2 strength.
- Repotting: Repot when root bound, following the instructions given in “Planting” above.
Watering is the most challenging part of keeping aloe vera healthy, but it’s certainly not rocket science! The aloe is a succulent plant accustomed to arid environments, but its thick leaves still need sufficient water.
- Water aloe vera plants deeply but infrequently. In other words, the soil should feel moist after watering but should be allowed to dry out to some extent before you water again. If the soil stays overly wet, the plant’s roots can rot.
- To ensure that you’re not overwatering your plant, allow the top third of potting soil to dry out between waterings. For example, if your plant is kept in 6 inches of potting soil, allow the top 2 inches to dry out before watering again. (Use your finger to test the dryness of the soil.)
- Generally speaking, plan to water your aloe plant about every 2-3 weeks in the spring and summer and even more sparingly during the fall and winter. One rule of thumb for fall and winter watering is to roughly double the time between waterings (compared to your summer watering schedule). In other words, if you water every two weeks in summer, water every four weeks in winter.
- When watering, some excess water may run out of the bottom of the pot. Let the pot sit in this water so the soil absorbs as much as possible. Wait 10-15 minutes, then dump any remaining water.
