Pocket Botanist
Check these first
- Measure the hours of direct sunlight the plant receives.
- Check if the plant is crowded by other taller garden neighbors.
- Inspect the soil for signs of recent heavy fertilization.
Likely causes
Insufficient sunlight
Most likelyHow to tell: The stems stretch out and look thin as they reach toward the light source.
What to do: Move the plant to a spot with full sun. If it is in a container, rotate it every few days to keep growth even.
Excessive fertilizer
PossibleHow to tell: The plant grows very fast but the stems are weak and cannot support the foliage.
What to do: Stop fertilizing immediately. Catmint prefers lean soil and rarely needs extra nutrients.

When to worry
It is normal for catmint to open up a bit after a heavy bloom cycle. Worry if the stems are collapsing and touching the ground constantly.
Stopping it coming back
Prune the plant back by half after the first flush of flowers to encourage a dense, compact habit.

Questions people ask
- Should I stake my leggy catmint?
- Staking is usually a temporary fix. It is better to prune the plant back to encourage stronger, shorter growth.
- Will cutting it back kill the plant?
- Not at all. Catmint is very resilient and will quickly push out new, sturdier growth after a hard prune.
