Brown tips in ponytail palm can be caused by several factors, including:
1. Overwatering or under-watering.
2. Exposure to dry air or cold temperatures.
3. Build-up of minerals in the water.
To improve brown tips, try the following:
1. Adjust watering frequency to keep the soil moist, but not waterlogged. The best way to do this is by lifting the moss ball every 10 days. If it feels lightweight, it's time to water it. We offer a rule of thumb of every two weeks, but this may vary depending on indoor temperatures.
2. Increase humidity by misting the plant and avoiding placing it under air vents.
3. Use distilled or purified water to prevent mineral buildup.
Trim any brown tips with clean scissors to encourage healthy growth.
