String of pearls: leggy growth
Why has it gone leggy and bare?
On string of pearls, the likeliest cause is not enough light. Long bare stretches of stem between leaves, new leaves smaller than old ones, and the whole plant leaning toward the window.
- 1Not enough light
Ranked here because its light floor is bright-indirect — below that it stretches looking for more, and it will not stop until it finds it.
How to tell. Long bare stretches of stem between leaves, new leaves smaller than old ones, and the whole plant leaning toward the window.
What to do. More light, and closer to the glass than feels necessary. A south or east window within two feet of the glass, ideally hanging. Grown dim, the pearls space out and the strand goes bare.
- 2Never pinched back
Ranked here because trailing plants go bald at the base unless they are cut back periodically.
How to tell. A few very long stems rather than many short ones, with no branching at all.
What to do. Cut the long stems back to a node. It branches from below the cut, and the cuttings root, so you lose nothing.
- 3Never turned
How to tell. Growth heavily one-sided toward the window while the far side stays bare.
What to do. Turn the pot a quarter turn whenever you water.
Why that order, for this plant
The ranking above is not a generic list. It is computed from this species' own record — a watering interval of 12–21 days, a arid origin, a humidity floor of 20%, and a light range from bright-indirect to direct. Change those figures and the order changes with them.
That is the whole point of a per-species page. Leggy growth on a plant watered every three days and leggy growth on one watered every three weeks almost never have the same cause, and a list that ranks them identically is worth nothing to either owner. You can check the reasoning against the care fields on the species entry, which is where these numbers come from.
No percentages appear on this page. We have not run a grower survey, and a confident-sounding figure with no dataset behind it is worse than none. Order and distinguishing tests are what we can honestly give.
What Missouri Botanical Garden records
An independent authority on this species' problems, for comparison with the ladder above.
Watch for aphids and mealybugs. Plants tend to be picky about growing requirements and will exhibit shriveled pearls when overwatered, underwatered, or with improper light conditions.
