How to Repot a String of Pearls
Repot a String of Pearls every 2 to 3 years into a shallow pot that's 1 to 2 inches wider than the current pot. Use a gritty, fast-draining cactus or succulent mix. Wait about a week before the first watering so the freshly cut roots can callus over.
How to Know It's Time to Repot
String of Pearls has a shallow, fragile root system that fills its pot slowly, so the signs of a too-small pot are subtle. Watch for these four signals.
-
1Roots circle the bottom of the pot or push out through the drainage holes.
-
2The plant has roughly doubled in size since you last potted it up.
-
3Pearls at the base shrivel and don't plump back up after a thorough watering.
-
4Soil dries out within a day or two of a thorough watering.
One sign on its own isn't enough to act on, but two or more together means it's time. Most String of Pearls need a fresh pot every 2 to 3 years, since the small root system doesn't fill a pot quickly.
The Best Time of Year to Repot
String of Pearls recovers fastest from repotting during its active growing season, when warmth and bright light help the roots reestablish. Spring through early summer is the sweet spot.
Avoid repotting in winter, when the plant is essentially dormant and the freshly cut roots are slow to callus and heal. Use the map below to pin down your window.
How to Choose a Pot and Soil Mix
Pot Size
Move up to a pot that's 1 to 2 inches wider than the current pot. Look for a shallow pot rather than a deep one, since the roots only occupy the top couple of inches and extra wet soil below them invites rot.
Pot Material
Terracotta is the best choice for String of Pearls. The walls breathe, so the soil dries evenly between waterings instead of staying soggy underneath the trailing pearls.
Plastic and glazed ceramic work too, but you'll need to water less often to compensate for the slower drying. Whichever material you pick, make sure the pot has drainage holes. This plant rots fast in standing water.
Soil Mix
Mix one part standard potting soil with one part coarse perlite or pumice for the gritty, fast-draining blend String of Pearls wants. A pre-mixed cactus or succulent mix works just as well.
Skip moisture-control formulas and dense peat-heavy mixes. Both hold too much water for these delicate roots and lead to rot.
How to Repot a String of Pearls, Step by Step
-
1Let the soil dry out. Stop watering a week or two before you plan to repot. Dry soil falls away from the roots cleanly and gives the freshly cut roots a chance to callus before they meet new soil. Pre-watering invites rot in this species.
-
2Pick the new pot. Choose a shallow pot that's 1 to 2 inches wider than the current pot, with drainage holes. Layer an inch of fresh gritty mix in the bottom so the root ball will sit at the same height it did before.
-
3Lift the strands off first. Gently drape the trailing strands of pearls up over the edge of the pot, or rest them on a tray. The pearls bruise and snap easily, so handle the plant by the soil ball whenever possible.
-
4Slide the plant out. Tip the pot onto its side and gently work the root ball loose. If the plant is stuck, run a butter knife around the inside edge of the pot to release it. Try not to disturb the shallow root mat.
-
5Set it in the new pot. Center the plant at the same depth it was growing before, with the pearls right at the soil surface. Fill in around the sides with fresh gritty mix, pressing gently as you go to keep the plant upright.
-
6Wait a week, then water. Do not water immediately. Let the freshly cut roots callus over in dry soil for about a week, then water lightly and let the soil dry out before the next drink. Watering wet wounds is the fastest way to rot this plant after a repot.
What to Expect After Repotting
Weeks 1 to 2
A few pearls may shrivel or drop as the plant adjusts. As long as the strands stay attached at the soil line, the plant is fine.
Keep the soil dry for the first week, then water lightly. Give the plant bright indirect light or a few hours of gentle morning sun, and skip fertilizer for now.
Weeks 4 to 8
New pearls forming at the tips of the strands, or fresh side shoots from the base, are the clearest signal that the plant has settled in.
Resume your normal watering rhythm of waiting until the soil is fully dry. Start half-strength succulent fertilizer once new growth is visible, and build up to full strength over the next two or three feedings.
