False goat's beard · Astilbe

Why are my garden astilbe leaves turning brown at the tips?

Garden astilbes love moisture, so brown, crispy tips are almost always a sign they are thirsty or getting too much sun. Check your soil moisture first to see if the plant is drying out between waterings.

Check these first

  1. Feel the soil two inches below the surface.
  2. Observe how many hours of direct sun the plant receives.
  3. Check if the container has proper drainage holes.

Likely causes

  1. Insufficient Watering

    Most likely

    How to tell: The soil feels dry to the touch an inch or two down, and the plant looks generally wilted.

    What to do: Water your astilbe deeply every 2 to 4 days. Ensure the soil stays consistently moist but not waterlogged.

  2. Excessive Sun Exposure

    Possible

    How to tell: The brown tips appear on leaves exposed to the hottest part of the afternoon sun.

    What to do: Move the plant to a spot with more shade. If it is in the ground, consider adding a layer of mulch to keep the roots cool.

When to worry

Worry if the browning spreads rapidly across the entire leaf. It is normal for older, lower leaves to brown slightly as the season ends.

Stopping it coming back

Keep a consistent watering schedule and apply organic mulch around the base to retain soil moisture.
