Overwatering or underwatering
Both overwatering and underwatering can lead to brown tips on leaves. Overwatering can suffocate the roots and cause them to rot, while underwatering can stress the plant.
To combat this, you will have to adjust your watering routine. Ensure the plant is receiving the right amount of water based on its specific needs.
Check the soil moisture level before watering, if the soil is moist, hold off on watering again until it’s dry and make sure the pot has proper drainage.
Low humidity
Some plants (especially tropical ones) require higher humidity levels than what’s typically found indoors. Low humidity can lead to dry leaf tips.
You can increase humidity around the plant by misting it regularly and placing the pot in a tray of water to increase moisture around the plant.
Fertiliser issues
Excessive fertilisation or using the wrong type of fertiliser can result in nutrient imbalances, leading to brown leaf tips.
Make sure your plant has a balanced diet from an all-purpose fertiliser and ensure it contains trace elements as these are imperative to the overall health of the plant.
Salt build-up
Over time, salts from tap water or fertilisers can accumulate in the soil, especially if you are liquid feeding, which causes the leaf tips to turn brown.
Periodically flush the soil with distilled or rainwater to leach out excess salts. Water the plant thoroughly until water drains freely from the bottom of the pot.
Environmental stress
Exposure to extreme temperatures, drafts or direct sunlight can stress plants and lead to brown leaf tips, especially if you have recently moved them about.
Ensure the plant is in an appropriate location with the right aspect. Protect it from drafts and direct sunlight if needed.
Pests and diseases
Some pests and diseases, such as spider mites or fungal infections, can cause damage to plant leaves, including browning at the tips.
Keep an eye on your plant for signs of pests or diseases. If you identify any, treat the plant with the appropriate pesticide or fungicide. For spider mite, an eco-oil will get on top of them quickly.
