Will the brown tips turn green again?

No, the brown parts are dead tissue and will not recover. You can trim the brown edges off with scissors if you prefer the look.

Does tap water cause brown tips?

Sometimes, if your tap water has high mineral content, it can cause salt buildup. Try using filtered or rainwater if you notice persistent browning.

Marsh willowherb: brown tips, causes and fixes

Check these first

Feel the top inch of soil to see if it has dried out.

Likely causes

Low Humidity
Most likely
How to tell: The tips of the leaves become dry, crispy, and brown. This is common in homes with central heating or air conditioning.
What to do: Place the plant on a tray filled with pebbles and a little water to increase local humidity. You can also mist the leaves lightly every few days.
Drought Stress
Possible
How to tell: The entire leaf may start to curl or droop along with the brown tips. The soil will feel dry and pulled away from the edges of the pot.
What to do: Water the plant thoroughly until water runs out of the bottom. Maintain a strict schedule to ensure the soil never dries out completely.
