Winter can be tough on plants, especially on tropical varieties. But with a little preparation, you can protect your garden and keep your plants safe from the cold. Here's how:

Winter Care Tips for Tropical Plants

Cut watering: Reduce watering to prevent root rot. Cold + wet = dead roots.
Water before frost: Thirsty plants are more vulnerable. Water them before a cold night to prevent damage.
Wind protection: Wind is more harmful than temperature drops. Plant near structures like houses or trees for shelter.
Prepare for long cold periods: If cold weather lasts for hours, use all available protection, including Christmas lights and propane heaters.
Don't use dry fertilizer in winter: Heavy fertilizing encourages tender growth, which is more susceptible to cold damage. Sunshine Boosters liquid fertilizers are safe to use year around as their intake is controlled by reduced watering.
Use fabric covers, not plastic: Plastic can cook plants in the sun, while fabric allows better ventilation.

Photo above: we cover our plants in the nursery with a thin synthetic fabric (sintepon) called "frost cloth" or "strawberry cloth". It is light, breathable and allows light and water to go through unlike plastic that creates heavy water pockets.

Prepare for Cold Nights

Wrap plants: On cold nights, cover individual plants or trees with sheets or blankets to shield them from wind chill.
Use Christmas lights: A simple string of lights can add extra warmth, protecting your plants during frosty nights.
Use propane heaters: For added warmth in a larger area, place a propane heater near your plants. Make sure to follow safety guidelines and keep the heater at a safe distance from flammable materials. This can help maintain a few extra degrees of warmth, especially in more open garden spaces or temporary greenhouses. Always ensure proper ventilation to avoid harmful gas buildup.

Large Collections? Build a Temporary Greenhouse

Affordable winter greenhouse: For large plant collections, you don't need an expensive greenhouse. A mobile carport with plastic or fabric covering, costing around $200, can house up to 100 plants!

Photo above: Temporary wrapping around plant collection with a plastic or frost cloth protects from a windchill. It may also win you a few degrees even without a heater. In this particular case, according to our temp sensors, with 30F outside, it was 41F inside this "dome", no heaters used.

Southern Exposure and Garage Storage

Southern windowsills: Compact tropicals can thrive on southern-facing windowsills, getting plenty of sunlight during the day.
Move plants inside: If you have larger collections, move them into a well-lit garage for the colder nights or longer periods.

Key Factors for Survival

Cold duration: Tropical plants can survive brief cold spells but long durations, even above freezing, can be deadly.
Wind-chill: Wind chill can be harsher than the temperature itself.
Exposure: Southern-facing slopes hold heat longer, making them ideal for your plants.
Humidity: Proximity to lakes or oceans can create a milder micro-climate.
Gradual temperature Drops are safer. Plants adjust better to slow temperature changes than sudden cold blasts. Gradual cooling allows plants to prepare, reducing the risk of damage.

Strengthen Plant Hardiness

Health and maturity: Well-established, healthy plants are more cold-hardy.
Boost plant immunity: Use products like SUNSHINE-Epi to improve cold resistance. Apply it before and during cold snaps to protect your plants.
Healthy plant is hardy. Make sure to fertilize your plants on regular basis - healthier and stronger plants are more cold hardy.

With these steps, you can protect your plants and help them survive the winter months. Stay warm and keep your garden thriving!

How to Protect Tropical Plants in Winter

When Bigger means Better

Everybody loves shopping online nowadays, and plants are no exception. Buying plants by mail order is not uncommon anymore; it only takes one click, and luckily, there are many sources - from big shopping malls like Amazon to small backyard nurseries that sell their seedlings on eBay or Facebook - all delivered to your door. But plants are alive... So when doing your online plant shopping, you must ensure that you fully enjoy your experience and are happy with a healthy plant that a) doesn't die; b) recovers quickly; and c) starts growing fast, so you can see flowers and fruit as soon as possible.

The rule of thumb for shipping plants: bigger plants undergo shipping better, experience less stress, less leaf drop, and recover quicker than plants with smaller root systems. So when it comes to buying plants online, the bigger, the better. Unfortunately, many mail-order plant sources may sell you a tiny twig that has very few chances of surviving. Shipping is very expensive today, so shipping a bigger size plant may cost more than the plant itself.

Below is a piece of advice on how to make the best plant selection for your garden...

5 important rules on how to buy trees online

1. Find a source with bigger plants. Check reviews, ask friends for recommendations, inquire from the company about the size of their plants and how they pack their plants for shipping.
TopTropicals offers well-established, strong plants with developed root system, in container sizes 1, 3, 7, 15 gallon, directly from a tropical Florida growing farm. Our unique plant-packing techniques are state of the art!

2. Price not always reflects the size and quality of the plant
TopTropicals offers many deals, discounts and sales, while still providing the biggest and strongest plants grown in real tropical conditions.

3. Most fruit trees must be grafted to produce good fruit. Make sure you are not purchasing a seedling when it comes to Mango, Avocado, Peaches and some other trees with named varieties that don't come true to seed.
TopTropicals offers only grafted - Mango, Avocado and a large number of other tropical cultivars.

4. Pick up when possible from the nursery your ordered from, or get a delivery, instead of shipping the plants. A drive to the nursery will save you more time and money in the future, plus you can hand-pick the biggest and healthiest specimens.
TopTropicals is open 7 days a week for your convenience. Visit our Ft Myers Garden Center or Sebring Farm to select the biggest plants.

5. Take advantage of X-Large size plant material if you live outside the tropical zone and are trying to zone-push your tropical garden. Bigger plants will establish faster and have more chances to survive cold winters. Again, it will save you money in a long run (although bigger plants may be more expensive, but their survival rate is much higher when it comes to cold nights).
TopTropicals offers X-Large flowering and fruiting trees (7-15-25 gallons), and most of the varieties you see in our online store can be custom-ordered in big sizes. Delivery and installation available.

Cold protection for tropical plants

Pushing the limits of tropical gardening

The year is almost over but the winter is not. This Christmas weekend at our Sebring B-farm we had it down to 30F. As a tropical gardener, winter can be challenging, especially if you grow plants outside of tropical zones.

To protect your garden from the cold, consider the following:

1. Monitor freeze watches and be prepared to take action if necessary.
2. Create temporary structures like mini-greenhouses using PVC pipes, carport frames, or bamboo sticks to support covers.
3. Use covers such as frost cloth, cardboard boxes, blankets, and bed sheets.
4. Use Christmas lights and other heating elements, including propane heaters, to keep plants warm.
5. Add a layer of heavy mulch around plant trunks to protect them from the cold.
6. Apply plant boosters that improve cold hardiness, such as Sunshine Epi, Sunshine-Si, and Sunshine Superfood.

At TopTropicals B-Farm, we sprayed our plants with a special cold hardiness treatment Sunshine-Si and covered and wrapped everything we could. We also moved cold sensitive species inside greenhouses. All of our plants are looking great and happy!

Healthy Plants: Q&A from Mr Booster

Feeding Indoor Plants

Q: I am moving all my potted plants indoors as weather is cooling down. I still have Sunshine Boosters that I got from you in Summer. Do I need to continue fertilizing and how often, or should I wait until Spring?

A: Indoor plants add a vibrant warmth to your home, and can even improve the air quality. But most importantly, indoor plants give you access to year-round gardening. While majority of house plants are easy to maintain, they still require proper care to thrive.
Too many gardeners overlook the importance of fertilizing plants indoors. However, proper feeding is essential to grow healthy, vibrant plants. With outdoor plants nature sends rain and a plant will send new roots to find food, an indoor plant is limited to only what you will give it. That is why it is essential to feed your plants a healthy nutritious meal even indoors.
Many granular and slow-releasing fertilizers will recommend that you only feed your plants occasionally, but this is not the healthiest for plants, since they need to "snack" every day to satisfy their daily nutrient needs. When you feed a plant a large meal rarely, it cannot absorb the nutrients effectively, leftovers creating build up in soil (it's called "locked up nutrients") and that is why we specifically designed our fertilizers to be a light, daily nutritious meal for your plants - Sunshine Home for houseplants...

🌞 How to help your plants survive a hot summer

👻 When plants grow wings...

🌴 Twilight in the garden. Smokey is holding a glowing pumpkin. Sunshine is sipping cocoa.

Sunshine: "Smokey, why does that plant look like it wants to fly away?"
Smokey: "That’s the Bat Lily - Tacca. It’s rare, it’s weird, and it’s in bloom just in time for Halloween."
Sunshine: "Figures. You always find the spooky ones."

Meet the Bat Lily (Tacca)

Tacca is also called the Bat Lily or Devil Flower. This tropical wonder grows bat-shaped wings and foot-long whiskers. The black form (Tacca chantrieri) looks straight out of a gothic dream, while the white one (Tacca nivea) is ghost-like and elegant.

Some of our plants are blooming right now in the nursery — true Halloween magic! Blooms are delicate and may not travel, but the plants are strong and will flower again soon in your care.

White Bat Lily (Tacca nivea) in bloom with wide ivory wings

"The White Bat Lily (Tacca nivea) is bold and sculptural, with oversized ivory wings that command attention. Its pale bracts stretch wide above clusters of deep maroon flowers, and long, silvery whiskers spill gracefully through the foliage. In filtered light, the plant seems to glow from within — elegant, crisp, and perfectly balanced between the strange and the beautiful. If I could pick, I’d go with the White Tacca. It feels more architectural, more balanced — those oversized wings catch light in a way that shows off every vein and curve. It looks engineered by nature, almost like an alien design prototype that actually works.

The Black Bat Lily (Tacca chantrieri) feels alive with shadow. Its dark maroon wings and wiry whiskers make it look like something that fluttered out of the jungle at dusk. The bloom’s layered structure and near-black sheen give it a quiet power — mysterious, understated, but impossible to ignore. But if I were designing mood lighting for a greenhouse at night, the Black Tacca wins. It’s subtle, mysterious, like a secret only visible up close. Together, they’re perfect opposites — yin and yang of the tropical underworld: white for daylight, black for moonlight." — says Tatiana Anderson, Top Tropicals Plant Expert
