- Feel the soil to see if it is pulling away from the sides of the pot or garden bed.
Likely causes
Inconsistent Watering
PossibleHow to tell: The soil feels bone dry and the edges of the leaves look crispy or brittle. This happens when the plant goes through cycles of extreme drought followed by heavy soaking.
What to do: Water your tomatillo deeply every 2 to 4 days whenever the top inch of soil feels dry. Aim to keep the soil moisture steady rather than letting it swing between parched and flooded.
Heat Stress
PossibleHow to tell: The tips turn brown during the hottest part of the summer when temperatures exceed 95 degrees. The rest of the plant might look wilted during the day even if the soil is moist.
What to do: Provide a bit of afternoon shade using a shade cloth if the heat is intense. Ensure the plant is well mulched to keep the root zone cool.

When to worry
Worry if the browning spreads rapidly toward the center of the leaves or if the entire plant begins to wilt permanently. Minor tip browning is often just a reaction to a particularly hot afternoon.
Stopping it coming back
Maintain a consistent watering schedule and apply a layer of organic mulch around the base to stabilize soil moisture.
