Greenie Get the app Stretched, leggy growth
Why is my succulent stretching and getting leggy?
A succulent stretches because it is not getting enough light: it grows long, thin stems with wide gaps between the leaves as it reaches for the window. Move it to the brightest window you have, or add a grow light, and turn it regularly. Stretched growth does not shrink back, so cut off the leggy part, let it callus and replant it to get a compact plant again.
Check these first
-
Look at the spacing: new leaves far apart on a thin stem, with tight older growth below, means it has been stretching.
-
Check the direction: a plant leaning or bending towards the glass is reaching for light.
-
Consider the spot: a north window, a shelf away from the glass, or a dark winter, are common reasons.
-
Check its care sheet: most succulents want a sunny window, while a few, such as Christmas cactus, do better in an east- or west-facing window out of hot sun.
Causes and fixes
-
Too little light
How to tellLong, thin stems with the leaves spaced far apart, and the whole plant leaning towards the window.
What to doMove it to the sunniest window you have, usually south- or west-facing, or close to a grow light. Increase direct sun gradually, a little more every few days, because a plant used to shade can scorch if moved straight into strong sun.
-
Light from one side only
How to tellThe plant is compact on the window side but stretched and bent on the room side.
What to doGive the pot a quarter turn each time you water, so every side gets its share of light and the plant grows straight.
-
Dark winter months
How to tellStretching starts in late autumn or winter, even in a spot that suited it in summer.
What to doKeep it in the brightest place you have and add a grow light if needed. Keep it cooler and water much less in winter so it rests instead of pushing out weak growth.
-
Old stretching that has already happened
How to tellThe plant now gets good light and the new growth is compact, but a long bare stem remains below it.
What to doIn spring or summer, cut off the top with a short piece of stem, let the cut end dry and callus for a few days, then set it on dry, gritty cactus mix and water lightly once roots form. The old stump often sprouts new shoots, and many kinds also root from single leaves.
Stop it coming back
-
Give succulents the brightest spot in the house, ideally a sunny windowsill.
-
Turn pots regularly so the plant grows evenly.
-
Water less in winter, when light is low and growth slows.
-
Add a grow light if your windows do not get direct sun.
When to worry
When to worry
Some stretching in winter is common and is not dangerous; the plant is still healthy and can be cut back and restarted in spring. Worry if a stretched plant is also soft, translucent or black at the base, or the leaves turn mushy while the soil is wet: that is rot, usually from watering too much in low light. Take healthy cuttings from the top, let them callus and replant them in dry, gritty mix, then throw away the rotten part.
