Pocket Botanist
Check these first

- Check if nearby plants are shading your cheatgrass.
- Look at the distance between the leaf nodes on the stem.
Likely causes
Insufficient Light
Most likelyHow to tell: The stems are long, thin, and stretching toward the nearest light source. The plant looks sparse rather than dense.
What to do: Relocate the plant to a spot with full, unobstructed sun. Cheatgrass needs direct light to maintain a compact and healthy growth habit.
Overcrowding
PossibleHow to tell: Many plants are growing in a tight cluster, forcing them to compete for light. The stems are tall but weak.
What to do: Thin out the area by removing some plants to give the remaining ones more space. This allows each plant to access the light it needs to grow properly.

When to worry
Leggy growth is not fatal, but it makes the plant weaker and more prone to falling over. It is normal for the plant to grow tall as it prepares to produce seed heads.
Stopping it coming back
Ensure the plant is in a wide open space with no shade from trees, buildings, or other tall vegetation.

Questions people ask
- Can I prune my leggy cheatgrass to make it shorter?
- Pruning will not fix the underlying light issue. It is better to move the plant to a sunnier location.
- Will the stems thicken up if I give it more sun?
- The existing stems will not change much, but any new growth will be much stronger and more compact.
