Freeze-Damaged Palms and Shrubs in North Florida & South Georgia: Cut or Wait?

Wait. In North Florida & South Georgia, leave freeze-burned palm fronds and shrub branches until spring. UF/IFAS says to cut a damaged palm leaf only after 2 to 3 new leaves grow, and to prune other cold-hurt plants after they sprout. The exception is dead wood that could fall on a person or roof. Call Josh at (850) 888-5603.

Why the Brown Stuff Stays On

A frozen frond looks dead, and it is. It is also still doing a job. UF/IFAS palm researchers Monica Elliott and Tim Broschat say damaged leaves with any green left in them can help a palm through the next cold night, and that the leaf bases insulate the bud at the top of the trunk (UF/IFAS Okaloosa County). That bud is the only growing point a palm has. Lose it and the palm is gone.

The same logic holds for shrubs. UF/IFAS says not to prune cold-damaged plants right away, because the dead foliage helps insulate them from further injury (UF/IFAS Gardening Solutions).

Palms: How to Tell What You Have

You will not know whether a palm lived for a while. UF/IFAS says new growth may take 4 to 7 months to appear, and it may come out malformed. A healthy new leaf is the sign of life, and it can be a year before leaves look normal again.

Here is what to check:

• The spear leaf. The newest, unopened leaf in the center. If it pulls out easily and the base is rotten, the rot is heading for the bud. UF/IFAS says to remove the rotten spear and treat the exposed bud with a copper fungicide, no more than twice, and to follow the label. It calls this an attempt, not a guarantee.
• The trunk. Firm is good. A trunk that is soft, leaning, or snapped is a different problem.
• The fronds. Brown is not the same as dead bud. Cut only what is fully brown, and only after new leaves are growing.

Palms vary a lot. Sabal palms take our winters in stride, while queen palms are the ones that suffer in a hard freeze. Our palm care guide describes each, including why over-trimming hurts.

Shrubs and Ornamentals

For the rest of the yard, UF/IFAS gives a simple test. In spring, scrape the bark with a fingernail. Black or brown under the bark means the wood is dead. To be sure where to cut, wait until the plant starts to sprout.

Common after a freeze:

• Camellias and azaleas can lose flower buds. Damaged buds drop or open with brown centers.
• Split stems on azalea and bottlebrush may die back later. Wait until they do, then cut below the split into healthy wood.
• Bananas, gingers, and tropical hibiscus may die to the ground and still come back. Some gingers show nothing until April or May.
• Fertilizer waits until the danger of frost has passed.

The Calendar

In Tallahassee, NOAA's record from 1991 shows the median last 32°F night falls around March 13, and the latest was April 23, in 1993. In Valdosta, the median was March 4 and the latest April 8, in 2007. Treat mid-April as the earliest safe point for a big cut, then scratch-test before you commit.

A rough order: protect in January and February, watch in March, scratch-test in April, and cut in May once growth shows.

What Should Not Wait

Some things cannot sit until May:

• Fronds or limbs hanging over a walkway, a car, or the roof
• A palm that has snapped or is leaning
• A tree with a split trunk or a cracked limb after the cold
• Anything touching a power line, which is a call to your utility first

A tall palm with dead fronds overhead is not a ladder job. Josh does tree pruning and, for a palm or shrub that is truly dead and in the wrong place, tree removal. Cleanup, debris removal, and stump grinding are separate from the cutting and are quoted when you call.

Josh covers Tallahassee and Leon, Gadsden, and Wakulla counties, and in South Georgia, Valdosta and Thomasville. Before the next freeze, read how to prepare trees for a freeze, and for what to expect in spring see our freeze damage recovery guide. For the trees themselves, our winter tree care guide covers cold damage.

FAQ

Should I cut brown palm fronds after a freeze?

Not right away. UF/IFAS says wait until the palm has produced 2 to 3 new leaves. Fronds that are fully brown and hanging over something are the exception.

How long until I know if my palm survived?

New growth may take 4 to 7 months to show. A new leaf, even a bent one, means the bud is alive.

When can I prune freeze-damaged shrubs?

After they sprout in spring. UF/IFAS says new sprouts show where the live wood ends, so you know where to cut.

Can a frozen palm be saved if the spear pulls out?

Sometimes. UF/IFAS says to remove the rotten spear and treat the bud area with copper fungicide, no more than twice. It is not a guarantee, and a palm with a dead bud will not recover.
