The String of pearls, also known as Curio rowleyanus, is one of the most charming succulents you can add to your indoor garden. With their cascading bead-like leaves, these plants look like living jewelry draped along shelves and hanging pots. But when it comes to watering, the String of pearls has its own special needs—different from lush ferns or tropical houseplants you might be used to. If you’ve ever worried about overwatering or underwatering your String of pearls, you’re not alone! Let’s break down exactly how, how much, and how often to water Curio rowleyanus, making sure your “pearls” stay plump and happy.
How Often Should You Water String of Pearls?
Unlike many houseplants, Curio rowleyanus prefers to completely dry out between waterings. In general, you should water your String of pearls every two to three weeks. But remember, the actual timing can depend on:
- Season: During active growth (spring and summer), you may need to water a bit more frequently.
- Pot and soil: Smaller pots and fast-draining soil will dry out quicker.
- Home conditions: Bright, warm locations dry out faster than cool, shaded ones.
Quick tip: Don’t water on a strict schedule. Instead, check the soil! Wait until at least the top 2-3 inches of soil are bone dry before watering.
How Much Water Does Curio Rowleyanus Need?
The roots of String of pearls don’t like to sit in soggy soil. When you water, do so deeply—let water run out of the drainage holes at the bottom. This ensures the roots are reached, but the excess doesn’t stay trapped.
- For smaller pots: ¼ to ½ cup is usually enough.
- For larger pots: Pour until water starts dripping from the bottom, then stop.
Practical Watering Steps:
1. Touch the soil. If it feels dry at least 2-3 inches down, proceed.
2. Water slowly, so the soil absorbs rather than shunts the water to the sides.
3. Wait for excess water to drain out.
Never leave your String of pearls sitting in a damp saucer or pot cover; empty it out after about 15 minutes.
Should You Mist or Spray String of Pearls?
It’s tempting to spray the little spheres to make them shine, but Curio rowleyanus doesn’t need misting. In fact:
- Misting can increase the risk of rot and fungus, since the “pearls” store moisture already.
- Stick to classic soil watering and let the beads stay dry.
What Humidity Does Curio Rowleyanus Need?
Here’s some good news—the String of pearls is perfectly happy in most indoor environments. It doesn’t require high humidity. In fact, it prefers dry air, so your typical apartment is just fine.
- No need for humidifiers, pebble trays, or misting.
Is String of Pearls Sensitive to Overwatering?
Absolutely—overwatering is one of the most common reasons String of pearls suffers indoors.
Signs of overwatering include:
- Yellow, mushy leaves
- Pearls shriveling despite wet soil
- A musty smell from the potting mix
To keep your Curio rowleyanus healthy, always err on the side of underwatering.
Is String of Pearls Drought Tolerant?
Yes! String of pearls are drought tolerant thanks to their water-storing leaves. If you forget to water or go away for a few weeks, they’ll usually bounce back. Just don’t make it a regular habit.
Bottom Watering vs. Top Watering: Which Is Better?
Both methods work, but top watering is usually simpler for beginners. Pour water directly onto the soil and let any excess drain away.
- Bottom watering (setting the pot in a tray of water to let it soak up) can work for deep-rooted or very dry plants but is not necessary for everyday care.
What to Do With Excess Water After Watering?
After watering, always check the saucer or decorative pot. Pour out any water that collects—String of pearls roots are very sensitive to sitting in water. This prevents rot and keeps plants thriving.
Checklist for Watering String of Pearls:
- Wait until the soil is thoroughly dry.
- Water deeply but infrequently.
- Never mist the plant.
- Don’t let standing water linger in trays or covers.

Caring for String of pearls (Curio rowleyanus) is simple once you know the basics: wait for dry soil, water thoroughly but rarely, avoid misting, and always empty out excess water.
