Crispy Leaves on coffee plant
What's Happening
Primarily transpiration stress from low humidity (<50% RH). Secondary causes include fluoride toxicity from tap water building up in leaf tips, and root competition from multiple plants sharing a single nursery pot. Flexible branches indicate viability despite leaf loss.
How to Fix It
- 1
Switch to distilled, reverse osmosis, or rainwater to eliminate fluoride/chlorine salts.
- 2
If humidity is persistently low, create a 'humidity tent' using a clear plastic bag with small vent holes for 14 days to restart growth.
- 3
Thin out multi-plant pots: Coffee plants are often sold as 6-10 seedlings in one pot. Separate them into individual containers to reduce moisture competition.
- 4
Deeply saturate the soil once, then wait for the top 2 inches to dry. Avoid constant 'sips' of water.
How to Prevent It
Maintain 60%+ humidity via a dedicated micro-humidifier or clustering with high-transpiration plants like ferns. Use a hygrometer to confirm leaf-level humidity, not just room-level.
