A "ponytail stump" (also known as a Ponytail Stump Palm) is essentially a Beaucarnea recurvata that has had its main trunk cut at a certain height to encourage multiple heads of foliage to sprout from the top. Because they store water in that bulbous base (the caudex), they are incredibly hardy and perfect for "forgetful" gardeners.  

Here is a concise care guide to keep your stump thriving:

1. Light: The "Sun-Lover"

• Best Spot: They thrive in bright, indirect light or even full sun. A south- or west-facing window is ideal.  

• Low Light: They can tolerate lower light, but they will grow very slowly and the "ponytail" leaves may become thin or pale.  

• Tip: Rotate the pot every few weeks so the foliage grows evenly on all sides of the stump.  

2. Water: The "Less is More" Rule

• The Golden Rule: Only water when the soil is completely dry. Depending on your home's humidity, this usually means once every 2 to 4 weeks.  

• How to Water: Give it a deep soak until water runs out of the drainage holes, then empty the saucer. Never let the stump sit in standing water, as this causes root rot.  

• Winter Care: During winter dormancy, you can cut back watering to once every 5 to 6 weeks.

3. Soil & Potting

• Soil Type: Use a fast-draining mix, like a cactus or succulent potting soil.  

• The Pot: Ensure the pot has a drainage hole. These plants actually prefer being slightly root-bound, so don’t rush to move it into a massive container.  

4. Maintenance & Troubleshooting

• Brown Tips: This is common and usually caused by either underwatering or a buildup of salts from tap water. You can trim the brown tips off with clean scissors—just follow the natural curve of the leaf.  

• Soft Stump: If the base (the "stump" or bulb) feels squishy or soft, it’s a sign of overwatering. Stop watering immediately and let the soil dry out completely.  

• Feeding: They aren't heavy eaters. A balanced liquid fertilizer diluted to half-strength once or twice during the spring and summer is plenty.
