Check these first
- Check if the water is moving or completely still.
- Test the water hardness levels.
- Inspect the tips for any signs of physical damage.
Likely causes
Poor water circulation
Most likelyHow to tell: Tips turn brown and mushy in areas where the water is stagnant.
What to do: Add a small water pump or air stone to increase movement. This helps distribute nutrients and oxygen evenly.
High mineral content
PossibleHow to tell: Tips turn brown and brittle, often with a crusty residue.
What to do: Perform a partial water change using distilled or reverse osmosis water. This lowers the concentration of dissolved minerals.

When to worry
Worry if the browning spreads down the stem toward the roots. A single brown tip on an otherwise healthy plant is usually not a cause for alarm.
Stopping it coming back
Keep the water moving gently and perform regular partial water changes to prevent mineral buildup.

Questions people ask
- Should I cut off the brown tips?

- Is my water too hard?
- Eurasian watermilfoil prefers moderate water conditions. If your water is very hard, it may cause mineral deposits that lead to tip burn.
