The honest answer about string of pearls difficulty is that it sits in the moderate range. It is harder to keep than a pothos or snake plant but easier than a fiddle leaf fig or calathea. Most of the challenge comes from learning one skill: when to water and when to walk away.
I killed my first two string of pearls plants before the third one made it past three months. Both times the cause was the same. I watered them every week because the soil looked dry on top and I wanted to take good care of them. What I did not realize was that the soil below the surface still held moisture, and those weekly soakings rotted the roots from the bottom up. The turning point came when I forced myself to wait until my finger came out bone dry after pushing it a full inch into the soil.
NC State calls this plant very particular about its growing conditions. That explains why so many people struggle with it. The trickiest part is figuring out problems because wilting means two opposite things. Soft mushy beads point to overwatering and root rot. Wrinkled deflated beads mean your plant needs water. If you get this wrong and add water to a rotting plant, the damage speeds up fast.
People who say string of pearls is string of pearls hard to grow tend to make the same three mistakes. First, they use regular potting soil that holds too much water instead of a fast-draining cactus mix. Iowa State recommends a soil ratio of 1 part organic to 2 parts mineral like perlite or coarse sand. Second, they plant it in a decorative pot with no drainage hole, which turns the bottom of the pot into a swamp. Third, they place it in a dim corner where it stretches and weakens instead of giving it 6-8 hours of bright indirect light per day.
Use the Right Pot
- Pot material: Terracotta pulls moisture out of the soil through its porous walls, giving you a safety buffer against overwatering mistakes.
- Drainage hole: A pot without a drainage hole traps water at the bottom and creates conditions for root rot even with careful watering.
- Pot size: Choose a pot only 1-2 inches wider than the root ball since too much extra soil stays wet and causes problems.
Pick Fast-Draining Soil
- Quick option: Buy a bag of pre-mixed cactus and succulent soil from any garden center and mix in an extra handful of perlite.
- Custom mix: Combine 1 part potting soil with 2 parts perlite or coarse sand for a blend that drains in seconds after watering.
- Why it matters: Regular potting soil stays wet for days and smothers the fine roots that need air pockets to stay healthy.
Water Only When Dry
- The finger test: Push your finger one inch into the soil and water only if it comes out completely dry with no dampness at all.
- Typical schedule: Every 2-3 weeks in spring and summer, stretching to once a month during winter when growth slows down.
- When in doubt: Wait three more days before watering because this plant recovers from drought far better than it recovers from overwatering.
The routine for keeping string of pearls alive is simpler than most people expect once you get past the learning curve. Check the soil every week or two with the finger test. Water deeply when it is dry, then leave the plant alone until next time. Feed at quarter strength once a month in the warm months and skip fertilizer in winter. That is the whole routine.
Once this rhythm clicks into place, the plant becomes one of the easiest in your collection. The beads stay plump, the strands grow longer each month, and you stop worrying about whether you are doing something wrong. A terracotta pot, cactus soil, and patience with watering solve 90% of the problems that make this plant seem harder than it is.
