Brown tips can follow prolonged wetness or root rot, a mix kept dry too long, intense direct sun after low-light exposure, fertilizer salts, unsuitable water quality, cold, dry air and pests.
Aloe vera brown tips: what to check
Check the leaf and root conditions before changing water. Aloe vera brown tips can follow wet roots, prolonged dryness, intense sun, fertilizer salts, water quality, cold, dry air or pests.
Check the leaves, stems and pot
What kind of brown mark is it?
Record whether browning is confined to dry leaf tips, runs along margins, appears as soft dark tissue or follows a sun-facing side, and whether leaves are also thin, yellow, spotted or collapsing.
Check whether the succulent mix has dried between waterings or stays wet, whether drainage holes are open, how much direct or bright light the plant receives, whether water or fertilizer changed, and whether pests or root damage are visible.
Use the visible signs to choose the next check
Possible causes and next checks
Correct the observed condition: let a saturated root zone dry and inspect drainage, restore thorough watering after excessive dryness, acclimate gradually to stronger sun, keep winter watering lighter, and pause extra fertilizer while checking for pests.
Watch for new damage or recovery
What to watch on new leaves
After light, water and fertilizer inputs have been stable, compare new growth with the same leaves and inspect the mix. Ongoing browning, soft tissue or collapse needs another root and exposure review.
Do not diagnose from one sign alone
