We spend a lot of time subtly encouraging our readers NOT TO OVERWATER YOUR PLANTS đ« (ok, maybe not so subtly) – but underwatering is not the answer either as you surely know. You have an underwatered aloe plant in your care and are wondering what in the world can be done to save it.
Aloe vera is one of those plants thatâs a bit more likely to be underwatered than the average pothos due to its reputation for doing so well in dry soil. So well, in fact, that you just⊠forget to water it altogether đł In fact, an aloe plant should be watered at regular intervals; once every week or two to keep it healthy and happy! Like other medicinal plants, aloe wonât cure so much as boredom if you donât attend to it somewhat regularly. Buuut, youâre not there yet; first you have a rescue mission to accomplish. Weâve put together all of our rescue tips in this article for how to save an underwatered aloe plant quickly and effectively, and what to do when you see the most common warning signs of a parched aloe plant.
what does an underwatered aloe plant look like?
Plants absorb nutrients from the soil through water, which transports both water and essential nutrients throughout the plantâs root and stem system to plant cells. Plants like aloe that hold lots of moisture in their tissues (succulents and cacti in particular) can go longer than regular plants without water. In nature, this cycle is totally normal! Aloe plants donât get much rain in the wild, arid regions in which they originate, and they often wait long periods between precipitation events (in weather lingo, this means water falling from the sky, AKA rain; a show-stopper in the most literal sense).
When aloe is kept indoors, it thrives with a regular watering schedule that keeps nutrients and moisture hydrating its fleshy leaves. Underwatering your aloe will leave the plant dehydrated and malnourished!
When plant-whispering, you need to listen to its leaves. An underwatered aloe plant will show you itâs dehydrated when its sword-like leaves droop, turn yellow, or dry out at the tips (if your aloe plant is droopy but not de-hydrated, thatâs another story).
When left for too long, the leaves will start to shrivel up like raisins and curl inwards (not good). If you can recognize the most common signs of an underwatered aloe plant by keeping an eye on its leaves, you should be able to save your plant before itâs too late:
- brown tips. The tips of the leaves are the last part of the plant to receive water and nutrients, so they will be the first place to start to show signs of dehydration. When underwatered, the tips of your aloeâs leaves will dry out, shrivel, and turn brown. You may also see brown edges along its leaves.
- wrinkles. Moisture retention makes the leaves plump, which should feel full and dense when squeezed gently, and not have any give. Deflated, wrinkly, or droopy aloe leaves mean the plant is having to tap its own moisture to survive a period of drought. This is what aloe is adapted for, but too little water will begin to put some stress on the plant.
- yellowing. Your aloe’s yellow leaves signal distress. While yellowing leaves can also be a sign of overwatered aloe plants, very dry potting soil will confirm that your plant isn’t getting enough moisture. An underwatered aloe plant wonât be able to absorb nutrients from the soil, which it requires to perform photosynthesis. Unable to produce chlorophyll, the aloe vera will lose its characteristic dark green color and begin to turn yellow. When the plant is especially dehydrated, it will turn brown and may develop even darker spots along the edges of the leaves.
- drooping. As your aloeâs leaves lose moisture and nutrients, they will lose their proud crown shape and start to droop. Without water retained at the cellular level of the plant, it wonât be able to hold itself up anymore and will start to bend under its own weight.
- curling. When an aloe plant begins to curl its leaves inwards, it is severely dehydrated and has lost a lot of moisture. The leaves begin to constrict to make the use of their remaining reserve more efficient. With less surface area to cover, the aloe leaves will continue to dry unless they receive moisture and nutrients to straighten out and start producing energy again.
how to save an aloe vera plant after underwatering
If you notice your aloe plant is showing signs of dehydration from underwatering, you should inspect the plant to evaluate its condition, then water it and move it to a spot with moderate light. Depending on the extent of damage from dehydration, an underwatered aloe vera plant will be able to absorb the nutrients it needs to perform photosynthesis, store moisture, and regain its firm structure relatively soon after a spell of underwatering. These plants have spent thousands of years adapting to drought conditions, after all!
Step 1: water your aloe plant
You have two options to water your underwatered aloe plant: Either soak its soil and set it aside to absorb the water and drain away excess, or use a spray bottle to deliver less water more frequently to nurse it to health. Using a spray bottle will minimize your chances of overwatering the aloe plant during your regular watering schedule. If you use a spray bottle, be sure the plantâs leaves donât stay consistently moist.
Step 2: remove damaged leaves
Most of the time, yellow leaves will regain their green color after a few days once given water, although their bounce-back depends on the size of the plant and the extent of its dehydration. However, some leaves that have been damaged by dehydration may not be able to recover from the stress to the plant cells and tissue, whether from the lack of moisture or from excessive bending. Remove damaged or dried aloe vera leaves to redirect energy to supporting healthy growth of the surviving portions of the aloe plant.
Step 3: set the plant in indirect sunlight
Aloe plants recovering from dehydration should be put in indirect light or (temporarily) a location with moderate light. This will help the plant retain moisture as it recovers. Direct sunlight can speed up a plantâs dehydration, and may result in the plant not getting enough water despite being on a regular schedule. Warm temperatures and direct sunlight evaporate water from the soil, in addition to encouraging transpiration from the plant itself.
Step 4: support weak leaves
Project perk-up: When aloe leaves have weakened to the point that they droop and bend, they will definitely benefit from some support while the plant heals. You can set up a small string fence in the pot around the aloe to hold the leaves vertically while it regains its strength and remove some of the stress on the plant.
What you will need:
- String
- 4-5 bamboo or wood sticks about 10 inches long
- Scissors
Gently bring the droopy leaves up to the center, and tie them together temporarily while you build the support around it. Stick 4-5 bamboo poles in the pot around the plant, and tie the string between each pole around the aloe, creating a small fence-like structure. Make 3-4 levels of string fencing around the aloe, which will hold the plant upright as it recovers.
tips for reviving a dehydrated aloe vera plant
Hurray, you saved your plant! Now⊠How did we get here? Itâs time to reflect on the maintenance schedule you kept for your plant so you donât make the same mistakes again – or at least, do better this time âșïž Here are some general tips to keep in mind when re-adjusting your watering schedule;
- Aloe vera likes a lot of bright, indirect light rather than direct sun. Even though itâs a desert plant, high temperatures and direct sunlight can burn the leaves and contribute to dehydration and stress. Heat and direct sunlight also dry out the soil more quickly. Generally, aloe plants only need to be watered once or twice a week. A moisture meter can help you be sure youâre not overwatering.
- A soil moisture meter will help you be sure your aloe plant isnât getting more water than it needs. If you donât want to feel the soil with your fingers, or your aloe is in a deep pot, a moisture meter will show you the water content of the soil before you add more. Aloe likes the soil to dry out completely before its next watering, so verifying the moisture content is an important way of avoiding soil saturation.
- Aloe shouldnât be watered more than once a week. A spray bottle is a great way to control how much water your aloe is getting, and monitoring the plant for its responses to the amount of water youâre giving it will help you be sure the plant is on the right watering schedule. Be sure the leaves dry completely and donât stay moist, however, as the plant doesnât like high humidity.
- Use well-draining soil in pots with drainage holes. The best soil for aloe vera is a dry potting soil mix specifically made for cacti and succulents. These mixes usually are at most 50% potting soil and the rest coarse material like orchid or pine bark, coco coir, and sphagnum moss. These solids keep the soil porous to maintain the oxygen content, fill up space where water wonât sit, and drain the water down with their non-absorbent surfaces.
