❄️Cold Night Survival Guide

Smokey and Sunshine Prepare Plants for the Cold Night.

Smokey: Come on, Sunshine, help me move these plants inside before it gets dark!
Sunshine: I am helping... see? I’m supervising the mango tree.
Smokey: You call that supervising? The frost cloth’s upside down!

When the forecast drops into the 30s, panic is not a plan. This is your simple, clear checklist to protect every tropical in your garden. Think of it as the quick emergency manual that goes hand in hand with the previous cold-weather newsletter.

"We all love our tropical flowers, mangoes, bananas, and rare fruit trees. A single cold night does not have to be a disaster. The key is knowing what to do, when to do it, and what mistakes to avoid." - Tatiana Anderson, Top Tropicals Plant Expert

🌡️ FROST AND FREEZE

A frost and a freeze are not the same. A frost is when you see ice crystals on leaves or grass, while a freeze is when the air temperature drops below 32 F. The tricky part is that you can get frost even when the air is above freezing, and you can have a freeze with no frost at all. It all depends on humidity and the dew point. If the dew point is below freezing, the ground can cool faster than the air, letting frost form even when your thermometer reads 35 or 36 F. And once the air itself drops below 32 F, even for an hour, tender tropicals can be damaged. For plants, a freeze is far more dangerous, because freezing air pulls heat out of stems, branches, and roots. Frost usually burns leaves, but a true freeze can injure wood, kill buds, and damage the entire plant.

WHAT TO DO AND NOT TO DO BEFORE A COLD SNAP

✔️ 5 THINGS TO DO:

1. Water well. Hydrated plants tolerate cold better than dry, stressed ones.
2. Add mulch. A thick layer around the base keeps roots warm.
3. Block the wind. Move pots to a sheltered corner or patio.
4. Cover at night, uncover in the morning. Let plants breathe and get light.
5. Add gentle heat if needed. Non-LED Christmas lights or a small old style 15-20W light can raise temps a few degrees.

❌ 5 THINGS NOT TO DO:

1. Do not prune or trim. Fresh cuts freeze first.
2. Do not overwater. Wet, cold soil invites root rot.
3. Do not let plants dry out either. Wilted plants freeze more easily.
4. Do not use dry fertilizer. Gentle liquid feeds like Sunshine Boosters are safe to use with every watering: its intake naturally slows down as watering decreases.
5. Do not look only at the thermometer. A long, windy night can be worse than a short freeze.

TEMPERATURE ACTION GUIDE (40 to 25 F)

• 40 to 38 F: Move potted plants to shelter, water soil, and cover tender tropicals.
• 37 to 33 F: Use frost cloth and anchor it down so the wind does not lift it.
• 32 to 30 F: Add a heat source like non-LED lights.
• 29 to 25 F: Double-cover sensitive plants, wrap trunks, and protect roots heavily.

COLD TOLERANCE BY PLANT TYPE

Before a cold night, it really helps to know your plant’s exact cold limits. Every species is different, and young plants are always more sensitive than mature ones. Take a few minutes to look up your varieties in our Tropical Plants Encyclopedia — it will tell you the safe temperature range, how much protection each plant needs, and which ones must be covered or moved before the next cold snap hits.

• Bananas: leaf burn below 37 F
• Mango, Annona: hurt around 32 F
• Cold hardy avocados: Mature tree can take about 25 F. Young trees must be protected
• Olives, Citrus, Guava, Jaboticaba: usually OK outside with mulch

QUICK-ACTION TABLE

Before the cold arrives, make yourself a quick list of every plant and what action each one needs. It saves time when temperatures start dropping and keeps you from scrambling in the dark. Check that you have enough frost cloth, blankets, and supplies on hand so you can cover everything without rushing. Planning ahead makes cold nights much less stressful.

• Bring Indoors: Cacao, Bilimbi, Coffee. They need warm, bright light.
• Cover Outdoors: Mango, Jackfruit, Banana, Annona. Use frost cloth, not plastic on leaves.
• Leave Outside: Eugenias, Peaches, Persimmons, Longan, Lychee, Papaya, Citrus, Loquat, Hardy Avocado. Add mulch and monitor overnight lows.

GADGETS AND TOOLS THAT HELP

• Indoor helpers: LED lights, small heaters, bottom-heat mats, timers.
• Outdoor helpers: frost cloth rolls, mini greenhouses, non-LED Christmas lights or small incandescent lights, smart thermometers.

Always keep electrical safety in mind, especially if you are using extension cords outdoors. Use only weather-rated cords, keep all connections off the ground, and protect plugs from moisture. Make sure heaters and lights are stable, secured, and never touching fabric covers. A few minutes of safety check can prevent a dangerous situation on a cold, wet night.

And if you want to keep plants strong through winter, add Sunshine Boosters to your watering routine. It is gentle, safe in cold weather, and gives plants an extra edge.

AFTER THE COLD PASSES

In the morning, uncover plants. Leaving covers on during the day can trap heat and cook the tender new growth, especially under the sun. The only exception is true frost cloth designed for all-day use, which allows air, light, and moisture to pass through. Regular blankets, sheets, and plastic must come off as soon as the sun rises.

Do not cut anything yet. A plant can look completely dead after a freeze, but many branches are still alive under the bark. Cutting too soon removes wood that would recover on its own. Wait until new growth begins in spring. That is when you can see exactly which branches are truly dead.

Use the scratch test. Gently scratch the bark with your nail or a small knife. If the layer underneath is green, the branch is alive. If it is brown and dry, it is likely dead. But even then, wait until warm weather to be sure, because sometimes only the tips die back while the lower part of the branch survives.

Once the weather stabilizes, resume light feeding. Plants coming out of cold stress need gentle support, not heavy fertilizer. A mild liquid feed like Sunshine Boosters helps them rebuild roots and push new growth without burning tender tissue.

WHAT NOT TO DO

• Do not prune right after a freeze.
• Do not overwater cold soil.
• Do not fertilize heavily until spring.
• Do not leave covers on in full sun.

CLOSING THOUGHT

Your tropical garden can survive any cold night if you prepare right. Cold snaps always feel stressful in the moment, but once you know your plants, have the right supplies, and follow a simple plan, it becomes routine. A few minutes of preparation before dark can save months of growth and keep your collection healthy all winter.

Frost cloth is the true workhorse of cold protection: it keeps heat in, keeps frost off, and will not suffocate plants the way plastic or blankets can. Having a few rolls ready means you never have to scramble at the last minute. Sunshine Boosters give your plants gentle support during the colder months so they stay strong enough to bounce back quickly when warm weather returns.

A little planning now will pay off in spring, when your mango, banana, citrus, and all your favorite tropicals come back happy and ready to grow.

The most rewarding hardy fruit trees

Q: Recently I started working remotely and I kinda like it, no need to commute, it saves me so much time so I can have life now! My friend got me involved into growing some small houseplants but I really want to take advantage of our Florida climate and sun. I want to plant some cool fruit trees since I have a decent size yard. But I live in Florida Panhandle and we do have some occasional freeze in winter, although not for too long. But it gets very hot in summer! Are there any tropical fruit trees that will be happy here? Or should I keep everything in pots? I am excited to have my own tropical plant collection!

A: There is a perfect plant for everyone, and a perfect tree for every climate. Many tropical and especially subtropical plants can be much hardier than they are believed to be, both flowering and fruiting trees among them. You may keep the most sensitive species in pots and bring them inside for winter, while there are so many trees that will be happy in your area. Start with these that are perfect for climates with hot summers and cool winters:

1. Peaches and Plums

Low-chill, Heat-tolerant Peaches, Nectarines, Plums are especially selected for Florida hot summers. They produce well and do not require many "chill" hours like temperate fruit trees. They only need 150 chill hours and grow well in even in Arizona, so you know they are taking the heat.

2. Figs

2) Fig trees - they are easy to grow, heat- and drought- resistant trees. They are prized for their delicious fruit, which can be one to three inches in length, violet, brown or black. There are even varieties with yellow fruit. Most fruits are borne from early summer to late fall on new growth, and the fruits generally mature very quickly. These trees are sensitive to frost only when actively growing, but can withstand 10F when dormant. Read more about Fig trees.

While traveling through the vibrant and diverse Caribbean, we acquired three exquisite local paintings. Two of these are masterfully rendered on jacaranda wood plates, and the third is beautifully crafted on a calabash. These stunning pieces of art celebrate the three most spectacular and revered flowering trees of the Tropics: Yellow Poinciana, Jacaranda, and Royal Poinciana.

These trees are not only visually stunning but also deeply embedded in Caribbean culture, legends, and folk remedies.

The Yellow Poinciana, with its bright golden blossoms, is often associated with joy and sunlight, symbolizing the warmth of the Caribbean spirit.
The Jacaranda, known for its striking lavender-blue flowers, is a symbol of wisdom and rebirth, often blooming in a breathtaking display that signals the change of seasons.
The Royal Poinciana, with its fiery red and orange flowers, is a symbol of passion and energy, often referred to as the "Flamboyant" tree due to its bold and dramatic appearance.

These trees hold a special place in the hearts of the Caribbean people. They are featured in numerous local stories and songs, and their flowers and leaves are used in traditional remedies and rituals. Owning these paintings feels like possessing a piece of the Caribbean's soul and its natural beauty.

Now, we are fortunate to have not only the paintings but also the actual trees. Watching them grow and bloom in our garden brings a piece of the Caribbean to our home, a constant reminder of our travels and the vibrant culture we experienced. These trees and their representations in art are a testament to the region's rich heritage and its enduring connection to nature.

Get them now while we have them. No need to go too far into Caribbean!

Peltophorum africanum - Golden Flamboyant, Yellow Poinciana. An excellent garden shade tree, beautiful in flower. This variety starts flowering at young age, in 3 gal pot.

Jacaranda mimosifolia - Hypnotizing bluish-purple, trumpet-like flowers create the magical image of the tree. Incredible, long-lasting purple blooms. When the trumpet-shaped blooms finally fall, they form a lilac carpet beneath the awe-inspiring Jacaranda for luxuriant curb appeal...

Royal poinciana, Flamboyant tree, Delonix regia - "One of the most spectacular flowering trees in the USA, and probably among the top 10 on this planet. In full bloom, it is like a regal elephant caparisoned in red and yellow brilliance." (Larry M. Schokman, The Kampong, National Tropical Botanic Garden)
