Browning tips, drying leaves, crispy edges... Don't panic! This guide helps you diagnose the cause (dry air, watering, hard water, over-fertilization, light, pot) and apply the right solution. Bonus: gentle nutrition with Fertilaine to revive more resilient plants.
Express Symptoms (recognize the problem in 10 seconds)
- Brown and dry tips: air too dry or irregular watering.
- Dark brown and brittle edges: lack of ambient humidity, direct heat.
- Brown spots after watering: hard/chlorinated water poorly tolerated by the species.
- Leaf yellowing then browning: overwatering in the pot (insufficient drainage) or nutrient deficiency/excess.
- Blackened tips near a window: sun scorching or temperature shock.
Quick Diagnosis (Decision Tree)
-
Substrate moisture test: push a finger 2–3 cm deep.
- Dry → increase watering frequency and/or surface mulching.
- Very wet → space out waterings and improve drainage.
- Check ambient air: heated/air-conditioned room = dry air → add a water tray + clay pebbles, group plants together.
- Assess light: direct sun on delicate foliage → move to bright indirect light.
- Watering/water: very hard/chlorinated tap water → let it sit for 24 hours or use filtered/rainwater.
- Fertilizer: if you fertilize often and the edges are burning → slow down, rinse the substrate, switch to gentle nutrition (see Fertilaine).
- Pot/roots: circling roots, pot too small → repotting + drainage layer.
Solution Sheets by Cause
1) Air too dry (heating, AC, winter behind a window)
Signs: brown tips, dry edges, curling leaves.
To do: group plants, add a water tray + clay pebbles, avoid misting fuzzy leaves (e.g., calatheas/fittonias ok, pilea/fern ok, peperomia/begonia on a case-by-case basis). Keep away from radiators and air vents.
2) Hard water or irregular watering
Signs: brown tips after watering, whitish deposits on the surface.
To do: let water sit for 24 hours (chlorine), alternate filtered/rainwater, water when the first inch is dry, drain the saucer well 20 minutes after watering.
3) Excess fertilizer or accumulated mineral salts
Signs: browned and dried edges, white crusts on the soil.
To do: rinse the substrate (let water run through the pot), suspend fertilization for 3–4 weeks, then resume with a slow-release organic fertilizer like Fertilaine to avoid burning and provide gradual nourishment.
4) Insufficient drainage / pot too small
Signs: leaf yellowing then browning, waterlogged soil, tight roots.
To do: repot in spring or during active growth, choose a pot 2–3 cm wider, add clay pebbles at the bottom + aerated mix (houseplant potting mix + perlite). Trim dead roots and clean the pot.
5) Light and temperature shocks
Signs: scorched areas near the window, rapid blackening after cold drafts or direct heat.
To do: bright indirect light for sensitive species, move away from windows in summer/midday, protect from drafts, maintain 18–24°C for most houseplants.
Gentle nutrition: why choose Fertilaine?
- Progressive release: avoids nutritional shocks responsible for burnt tips.
- Respects the substrate: promotes active soil life in pots (useful after rinsing/repotting).
- Easy to use: light top dressing or incorporation into repotting.

Monthly "anti-brown tips" routine
- Check substrate moisture (finger or gauge) and adjust watering.
- Turn the pot a quarter turn for even growth.
- Dust leaves with a soft cloth (no polish).
- Rinse the surface of the soil 1×/month if water is hard.
- Apply lightly an organic fertilizer like Fertilaine during the growing season (spring/summer).
