Frequently Asked Questions

How often should I water aloe vera?
Every 2–3 weeks in summer, 4–6 weeks in winter. Soil must be bone dry between waterings.
Can I use the gel from my aloe vera plant?
Yes — break a leaf at the base and apply fresh gel to burns or skin irritations. The inner clear gel is safe.
Why are my aloe vera leaves turning brown?
Brown and crispy = too much direct sun or underwatering. Brown and mushy = overwatering or root rot.
Does aloe vera need direct sunlight?
Bright indirect or gentle direct morning sun is ideal. Harsh afternoon sun scorches the leaves.
Is aloe vera toxic to pets?
Yes — toxic to cats and dogs. The latex layer (not the gel) causes vomiting and lethargy (ASPCA).
