Check these first
- Observe how many hours of direct sun the plant receives.
- Check if the plant is leaning toward a light source.
- Review your recent fertilizer schedule.
Likely causes
Insufficient light
Most likelyHow to tell: The stems are long and thin with large gaps between the leaves. The plant leans heavily toward the nearest window or light source.
What to do: Move the plant to a spot that receives full sun for at least 6 to 8 hours a day. If you are growing indoors, place it directly in a south facing window.
Excessive nitrogen
PossibleHow to tell: The plant grows very fast but the stems are weak and floppy. The foliage is dark green but lacks flowers.
What to do: Avoid using high nitrogen fertilizers during the growing season. Switch to a balanced, low strength fertilizer or stop feeding entirely.

When to worry
It is normal for the plant to grow tall as it prepares to bloom. Be concerned only if the stems are so weak they cannot support their own weight.
Stopping it coming back
Provide full sun exposure from the start to ensure strong, thick stems. Avoid over fertilizing which encourages rapid, weak growth.

Questions people ask
- Should I prune my leggy Scarlet gilia?
- You can pinch back the tips to encourage branching, but do this early in the season. Pruning too late may remove the flower buds.
- Will my plant recover its shape?
- Once a stem has stretched, it will not shrink back. Providing better light will ensure that new growth is much stronger and more compact.
