About String of Raindrops

Curio citriformis (syn. Senecio citriformis) · also called String of Raindrops, String of Tears · houseplant

String of raindrops is a trailing African succulent (Curio citriformis, formerly Senecio citriformis) grown for its plump, blue-green teardrop leaves that spill over a pot like falling rain. Its one defining need is sharp drainage: it stores water in those leaves and rots quickly in soggy compost, so let the mix dry out fully between drinks.

Mature size: Trailing stems reach around 60-90 cm (2-3 ft) long indoors over time; individual leaves are about 1-2 cm.

Watch for — Root rot from overwatering: The single biggest killer. Soggy or slow-draining compost turns stems and leaves soft, yellow and translucent. Always let the mix dry fully, use a gritty medium and a pot with drainage holes.

Indoor size vs how big it gets in the wild

String of Raindrops does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims. Indoors and in a pot, expect trailing stems reach around 60-90 cm (2-3 ft) long indoors over time. In the ground with no restriction it is a completely different plant — individual leaves are about 1-2 cm. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Growth rate and years to mature

String of Raindrops is a fast grower. Realistically, expect one to three growing seasons — fast vines can add a metre or more of stem in a single good summer. Its feeding profile backs this up: feed sparingly: a balanced houseplant or cactus feed diluted to half strength, around once a month through spring and summer only. it is a light feeder and over-fertilising produces weak, leggy growth. stop feeding entirely in autumn and winter while growth slows.

Want this turned into the right next pot at the right moment? The pot size calculator and the string of raindrops repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast string of raindrops grows.

How to keep string of raindrops smaller

You are not stuck with the maximum size. For string of raindrops specifically, these are the levers, in order of impact:

Trim the longest vines back to the length you want — string of raindrops takes hard cutting well and bushes out from the cut.
Cut just above a leaf node; each trimmed stem usually branches into two, so pruning makes it fuller, not sparser.
The cuttings root easily in water or mix, so "keeping it smaller" doubles as free new plants.
Expect to tidy it every few weeks in summer — this is a fast vine that will sprawl if left.

The keep-it-smaller method, step by step

Decide the length you want. Pick the point each vine of string of raindrops should stop — you can be aggressive; it regrows readily.
Cut just above a node. Snip about 0.5 cm above a leaf node so the stem branches there instead of dying back.
Root the cuttings. Drop the trimmed pieces in water or mix — they root in 2-4 weeks and can fill the same pot for a bushier look.
Repeat as it runs. Re-trim whenever it overshoots; regular light pruning keeps it both smaller and fuller.

How to grow string of raindrops bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for string of raindrops the accelerators are:

Good light plus a moss pole or trellis triggers the longest, fastest, largest-leaved growth.
Give it something to climb — many vines grow far faster and bigger up a support than trailing.
Feed through spring and summer and keep it consistently watered while it is actively running.

Light is almost always the ceiling. The string of raindrops light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When string of raindrops outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for string of raindrops:

Vines pooling on the floor or wrapping past where you want them — purely a trimming cue, not a repot one.
Bare, leggy stems with leaves only at the tips (usually a light problem, not a size one).
A tangled mass that has outrun its support and needs cutting back and re-training.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the string of raindrops repotting guide. If you want more of this plant instead of a bigger one, the string of raindrops propagation guide turns prunings into new plants.

String of Raindrops size — frequently asked questions

How big does string of raindrops get?

String of Raindrops reaches trailing stems reach around 60-90 cm (2-3 ft) long indoors over time when grown indoors, and far larger where it grows unrestricted (individual leaves are about 1-2 cm.). Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Is string of raindrops slow or fast growing?

String of Raindrops is a fast grower. Expect one to three growing seasons — fast vines can add a metre or more of stem in a single good summer. String of Raindrops does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims.

How long does string of raindrops take to reach full size?

Roughly one to three growing seasons — fast vines can add a metre or more of stem in a single good summer. Light, pot size and feeding move that timeline more than anything else.
