Can I prune back leggy stems?

You can trim back weak stems to encourage a tidier look. However, focus on fixing the light issue first so new growth comes in stronger.

Will my plant recover its shape?

The existing stems will not shrink, but new growth will be more compact once you provide better light. You can replace the plant if the current look is too messy.

Italian arum: leggy growth, causes and fixes

Check these first

Assess the amount of light the plant receives daily.
Check if the plant is leaning heavily toward a window.
Review your recent fertilizing schedule.

Likely causes

Insufficient Light
Possible
How to tell: The stems stretch out and become thin as the plant reaches toward the nearest light source. The leaves may also look smaller than usual.
What to do: Move the pot to a location with brighter, indirect light. Even though they like shade, they still need enough light to maintain a compact shape.
Excessive Nitrogen
Possible
How to tell: The plant produces rapid, weak growth that cannot support its own weight. This often happens if you use a high nitrogen fertilizer too frequently.
What to do: Stop fertilizing for the rest of the season. Switch to a balanced, slow release fertilizer at half strength only once in the spring.

When to worry

It is serious if the stems are so weak they collapse under their own weight. Some stretching is normal as the plant prepares for its dormant summer phase.

Stopping it coming back

Place the plant in a spot with consistent, bright indirect light. Avoid overfeeding to keep growth steady and strong.
