Why is my plant leggy? Stretched stems and bare vines

A PlantParlour plant problems guide

A leggy plant — long bare stems, leaves spaced far apart, growth leaning toward the window — is almost always short of light, and stretching to find more. Stretched growth never shrinks back, so the fix has two parts: move it somewhere brighter so new growth comes in compact, and cut the leggy stems back so the plant branches from below the cut. Many of those cuttings will root. Some plants go bare at the base as they age whatever you do, and that is normal.

Read the pattern first

How far is bright?

Much closer than most people think. Light falls away fast with distance from a window: a spot two metres back gets a small fraction of the light on the sill, even if the room looks bright to you. Moving a plant from the middle of the room to right beside the window is often the whole fix. In a dark room, a grow light does the same job.

How to prune a leggy plant

Cut each long stem just above a node — the point where a leaf joins, or joined, the stem. New shoots come from the nodes below the cut, so the shorter you cut, the bushier the regrowth. Spring and early summer are the best time. For vining plants, root the cuttings in water and plant them back into the same pot to fill it out.

Questions people ask

Will a leggy plant fill back in on its own?

Not usually. A bare section of stem rarely grows new leaves by itself. Cutting it back is what makes the plant branch.

Can stretched succulents go back to normal?

The stretched part can't. Move the plant into more light, then cut the top off and re-root it; the base usually sends out new rosettes.

Do grow lights help?

Yes. A plant doesn't care whether its light comes from a window or a lamp, as long as there is enough of it. Keep the light close to the plant and on a timer for 12 to 14 hours a day.

Other problems

Not sure which one it is?

PlantParlour's health check looks at up to three photos of your plant alongside the care you've logged for it — when you last watered, when it was repotted, problems it has had before — and tells you what it sees. Log the problem as an issue, take another photo in a few days, and the next check compares the two, so you can tell whether it is spreading or settling. It is an AI's considered guess, not a diagnosis, and it is free to start with no account.
