Should I prune leggy stems?

You can trim back the longest stems to encourage a bushier appearance. Use clean, sharp shears to make the cut just above a leaf node.

Will it flower if it is leggy?

This plant does flower in spring with small white blooms, but a leggy plant often lacks the energy to produce them. Improving the light will help it bloom better next season.

Starry false lily of the valley: leggy growth

Check these first

Move the plant to a spot with slightly more indirect light.
Check if the plant is near a heat source like a radiator.
Rotate the pot to see if the leaning stops.

Likely causes

Insufficient light
Most likely
How to tell: The stems are stretching out with large gaps between the leaves. The plant looks thin and leans heavily toward the nearest light source.
What to do: Move the plant to a location with brighter, indirect light. While it loves shade, it still needs enough light to maintain a compact shape. Rotate the pot every week to ensure even growth on all sides.
High temperatures
Possible
How to tell: The plant grows quickly but the stems are weak and floppy. The leaves may look smaller than usual.
What to do: Keep the plant in a cooler spot away from heat vents or direct afternoon sun. Aim for a location that stays consistently cool throughout the day. Proper air circulation can also help keep the stems sturdy.

When to worry

It is normal for the plant to stretch slightly as it reaches maturity. Be concerned if the stems are so weak they cannot support their own weight.

Stopping it coming back

Provide consistent, dappled shade and avoid placing the plant in areas with extreme heat.
