Northern spicebush · Lindera benzoin

Why are my spicebush leaves curling?

It is less common for spicebush leaves to curl, but it is usually a reaction to heat stress or a lack of water. Check the soil moisture first to see if the plant is drying out too quickly between waterings.

Check these first

  1. Check the soil moisture with your finger.
  2. Look at the time of day when the curling is worst.
  3. Check for signs of pests like aphids on the leaf undersides.

Likely causes

  1. Drought Stress

    Possible

    How to tell: The leaves look wilted and curl inward during the hottest part of the day. The soil feels dry more than an inch down.

    What to do: Water the shrub deeply until the soil is moist 6 inches deep. Apply a 2 to 3 inch layer of mulch around the base to help the soil hold onto moisture.

  2. Heat Stress

    Possible

    How to tell: The leaves curl during extreme heat waves even if the soil is moist. The plant usually recovers once the temperature drops in the evening.

    What to do: Provide temporary shade during the hottest afternoon hours if the plant is in a spot that gets too much direct sun. Ensure the plant is well watered before the heat of the day begins.

When to worry

Worry if the leaves stay curled even after you water and the temperature cools down. If the leaves turn brown and brittle while curled, the plant is suffering from severe dehydration.

Stopping it coming back

Maintain a consistent watering schedule and keep the root zone mulched to protect the spicebush from sudden temperature spikes.

Questions people ask

Is my plant dying if the leaves curl?
Usually, it is just a temporary defense mechanism to save water. It should perk back up once it gets a good drink.
Should I mist the leaves?
Misting does not help much. It is better to water the soil deeply so the roots can hydrate the entire plant.
