Prepping Houseplants for Hurricane Season in Florida

Hurricane advice in Southwest Florida is almost entirely about trees: what to prune, what to stake, which palms hold up. That is fair enough, since falling trees are what hurt people. But if your plants live in pots, on the lanai or the patio or in the living room, none of that advice applies to you, and the failure modes are completely different.

So this is the houseplant version, written for the way a lot of Gulf Coast collections actually live: half indoors, half on a screened lanai, all of it dependent on air conditioning.

The lanai is not shelter

A screened enclosure feels like a protected space, and in a hurricane it behaves like an open one. Screen cages fail regularly in storms that leave the roof entirely intact, and the moment the screen goes, every pot out there is loose in high wind. A ten-inch ceramic pot is a projectile aimed at your slider, or your neighbour’s.

Two days out, not the morning of. This is the part that matters most, and it is a scheduling point rather than a horticultural one. On the morning of a storm you will be filling bathtubs and moving patio furniture, and the plants will lose. Do them early.

• Bring everything you can lift indoors. A garage, a hallway, an interior bathroom: all fine. A week in poor light is nothing to a houseplant. Being thrown into a wall is.
• What you cannot lift, lay on its side against an interior wall of the lanai. A pot on its side cannot topple.
• Take down every hanging basket without exception.
• Water everything thoroughly beforehand, then stop. A well-hydrated plant handles heat stress better, and you may not want to be carrying water afterwards.
• Move indoor plants away from large glass doors and windows.
• Photograph the collection. It is dull and it settles insurance questions.

What losing power actually does to plants

People plan for the wind and are surprised by the aftermath, which is where most of the plant losses actually happen.

A closed Florida house with no air conditioning becomes very hot and very humid within a few hours and stays that way. For most tropical foliage the humidity is genuinely welcome, and this is the one week a year your calathea is happy. The heat is harder, and the real stress comes at the other end, when power returns and the house drops twenty degrees and dries out in an afternoon. Swings are what plants struggle with, more than any single condition.

The other loss is light. Shutters and plywood mean days of near-darkness, which causes leaf drop in ficus and general yellowing in almost everything. That looks alarming and is mostly recoverable. When you open the house back up, reintroduce light gradually: a plant that has spent five days in the dark will scorch in a window it handled comfortably the week before.

Salt through the screen

Barrier-island and near-coastal homes get one more problem that inland homes do not. Storm winds carry salt spray a long way inland, and screen does nothing to stop it. Salt on a leaf surface draws water back out of the leaf tissue by osmosis, which is why salt burn looks so much like drought damage: brown, crisped margins on a plant whose soil is perfectly moist.

The fix is fast and simple, and it works only if you do it soon:

• Rinse the foliage thoroughly with fresh water, both leaf surfaces.
• Flush every pot generously until water runs freely out of the drainage holes, carrying the salt down and out of the root zone.

If you are in Venice, on Manasota Key, or anywhere in Englewood near the water, this is worth doing after any storm that pushed spray inland, even one that did no other damage.

The two-week-later collapse

Here is the pattern I see every season, and it is the reason I wrote this post.

The storm passes. The plants look battered but alive. Everybody, quite reasonably, wants to help them, so everybody waters everything. And then two weeks later plants that survived the hurricane start dying.

What happened is that days of rain and a flooded lanai left pots saturated. Roots sitting in waterlogged, oxygen-starved soil are exactly what the water-mold pathogens behind root rot exploit. UF/IFAS notes the same effect in the landscape, observing that bud rot caused by Phytophthora occurs with greater frequency after tropical storms and hurricanes. See their write-up of Bud Rot of Palm. Adding more water to a saturated pot at that point is the last thing the plant needs.

Lift the pot. Heavy means wet. Wet means wait.

Alongside that:

• Do not fertilize. A stressed plant with compromised roots does not need salts added to its soil. Wait until it is visibly growing again.
• Do not prune what is still green. Remove broken and clearly dead material for hygiene, then leave it three or four weeks and prune to what actually died. Scorched-looking leaves are frequently still moving resources back into the plant.
• Watch for pests at the two-to-three week mark. Stressed plants get picked on, and a house that ran hot with the windows open often gets a flare of spider mites or mealybugs afterwards.

Make it a checklist, not a decision

The clients who come through storms best are not the ones with the toughest plants. They are the ones who already know what goes where, so that “two days out” is a list they work through rather than a set of judgement calls made while watching a forecast.

Write it down once, covering which plants come in, which get laid down, where they go, and who lifts the big ones, and next season it takes an hour.

Afterwards

The most useful visit is not in the first week. It is two to three weeks out, once it is clear what recovered and what did not, and it usually turns into triage: which plants are genuinely fine, which need their roots checked, which need repotting out of soil that never dried, and which are past saving.

That is a consultation, a flat $185 in-home anywhere from Sarasota to Port Charlotte. Grove members get a priority post-storm visit built into the program, specifically because this is the moment when a couple of hours of expert attention is worth the most. If you want the full before-and-after routine in one place, I have written it up as caring for houseplants before and after a hurricane. Get in touch before the season, and we will have your plan ready before you need it.
