Light and placement
Bright / direct light
Donkey’s tail needs several hours of direct sun. Turn the pot every week so it grows evenly. Place it directly in front of a south- or southwest-facing window.
Feeding
Feed your donkey’s tail every 90 days while it’s actively growing. Use a cactus and succulent fertilizer, which is lower in nitrogen, at half the strength on the label, and only on soil that’s already damp.
When growth pauses, skip the fertilizer and let it rest.

Why is my donkey’s tail turning yellow or drooping?
Yellowing, drooping and brown tips can have several causes. Check the potting mix before adding water and follow this plant’s watering and rest instructions. If the mix is still wet, do not add more water. Check drainage and roots, then light, humidity, water quality and pests. Faded color or webbing alone does not show that the roots need water.
