🩺 What's wrong with my Aloe Vera?

What is aloe vera?

Aloe vera is the world’s best-known medicinal succulent — a rosette of thick, pointed leaves filled with clear, soothing gel. It’s drought-proof, slow-growing, and one of the easiest plants to keep on a sunny windowsill, which is why it’s a near-universal houseplant.

How much light does an aloe vera need?

Aloe wants bright light, including some direct sun. In too little light it stretches, flattens, and goes pale. If you’re moving it into strong sun, do it gradually — a sudden jump to intense direct sun can turn the leaves brown or reddish as it burns.

How often should you water an aloe vera?

Water only every 2–3 weeks, and let the soil dry out completely first. In winter the plant rests — cut back to monthly or less. Like all succulents, aloe is far more likely to die from overwatering than from drought, so when in doubt, wait.

Why is my aloe vera mushy or shriveled?

These are opposite problems. Mushy, translucent, brown leaves mean overwatering and rot — act fast: dry it out and repot. Thin, curled, puckered leaves mean it’s thirsty — give it a good soak. Use the symptom checker above to match what you see.

Is aloe vera toxic to pets?

Yes — the ASPCA lists aloe as toxic to cats and dogs, due to saponins and anthraquinones that can cause vomiting and lethargy. The clear inner gel is considered edible, but the whole-leaf sap is what makes it a risk for curious pets, so keep it out of reach.

Frequently asked questions

How often should I water an aloe vera?

About every 2–3 weeks in the growing season, and once a month or less in winter. Let the soil dry out completely first — aloe stores water in its leaves and rots quickly if kept wet.

Is aloe vera toxic to cats and dogs?

Yes. The ASPCA lists aloe as toxic to cats and dogs due to saponins and anthraquinones, which can cause vomiting and lethargy. (The clear inner gel is considered edible, but the whole-leaf sap is the problem for pets.)

Why is my aloe vera going mushy or brown?

Mushy, translucent leaves mean overwatering and rot. Let it dry out, cut away affected leaves, and repot into fast-draining succulent or cactus mix.

Why is my aloe vera flat and floppy?

Usually too little light. Aloe stretches and flattens reaching for light; move it to a bright spot with some direct sun and it will firm up and grow more upright.
