Damage Done to Hibiscus Trees From Late Spring Frost

Hibiscus trees are susceptible to frost damage.

Late spring frosts can seriously damage a hibiscus plant, especially if the plant does not receive remedial care after the frost. Untended plants can be killed or prevented from flowering by frost.

Pruning

Most hibiscus plants benefit from early spring pruning, but late frosts can damage the newly pruned branches. However, most hibiscus plants will heal themselves and do not require further pruning.

Damage

Damage done by a late frost can affect the leaves, flowers and flower buds, roots and branches of the hibiscus tree. Frost can split the bark or wood of the tree, exposing it to insects and fungi that spread disease.

Frost Damage Prevention

The best way to protect a hibiscus from late spring frost is to ensure that it receives direct sunlight throughout much of the day. This will help lower the chances of frost damage and help the plant heal if damage does occur.
