How to protect tropical plants in Winter

Winter tips and podcast

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!

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...

10 common mistakes to avoid
with mail order plants

Q: How to get happy and healthy plants from mail order? Will they survive the trip and grow well after transportation? What mistakes should I avoid?

A: At Top Tropicals, we have over 20 years of experience shipping plants. We know how to pack them properly and ensure the safest journey possible. We ship the biggest and healthiest plants, and our customers are often amazed at how great they look after a few days in a dark box. But receiving a healthy plant is only half the adventure. Now that the plant is in your hands, it's up to you to keep it thriving. The first couple of weeks after shipping are critical. With the right care, your new plant can reward you with beautiful flowers and fruit for years to come. Here are 10 common mistakes to avoid when buying plants by mail order.

1. Not unpacking plants immediately
Leaving plants in the box too long can cause stress or damage. Unpack them as soon as they arrive to let them breathe and adjust.

2. Ignoring acclimation
Plants need time to adjust to their new environment. Don't place them in full sun or extreme conditions (heat, wind) right away.

3. Overwatering right after arrival
Many people water their new plants too much. Plants often need time to recover from transit, and too much water can cause root rot.

4. Stepping up too soon
Repotting immediately in a large pot can cause root rot. Plant in a pot just the size of a root ball, step up only after the plant is showing new growth.

5. Ignoring the plant's needs
Research the specific needs of your plant before it arrives. Light, water, and soil requirements vary greatly, and misunderstanding them can lead to issues.

6. Placing the plant in the wrong environment
It's important to give your plant the right temperature, light, and humidity based on its natural habitat. We grow tropical plants. They won't survive in areas with freezing temperatures.

7. Not trimming damaged branches.
Transit can cause minor damage to leaves or branches. Trimming these parts can help the plant recover faster.

8. Expecting immediate growth
Plants need time to adjust after the trip. Give them a chance to settle for a few weeks before expecting new growth or blooms.

9. Fertilizing too soon
Do not fertilize your plant right after arrival. Let it get established first - usually a few weeks - before adding fertilizer to avoid stressing the plant.

10. Not checking for pests
Always inspect new plants for pests. Shipping stress can lead to infestations, so a close check is vital.

By avoiding these mistakes and following the planting instructions included with your order, you'll be on the right path to creating your tropical paradise. Take care of your new plant, and it will thrive, rewarding you with vibrant growth for years to come.

How to overwinter tropical plants indoors

10 key tips for successful overwintering

Q: I have two Mandevillas that thrived on my balcony all summer. Now that cold weather is approaching, I've moved them indoors to bright spots, but they're dropping and wilting leaves. How can I keep them healthy until spring? Should I fertilize them? Can Mandevillas grow indoors year-round?

A: First, keep in mind that the plants we call "indoor plants" or "house plants" are all tropical. However, not all tropical plants are suitable for indoor living. Some, especially shade-loving ones, thrive in indoor conditions, which is why we refer to them as "house plants" (philodendrons, monsteras, calatheas, peperomias, and many others, including some succulents). Others are less adaptable to the lower light and humidity typical of indoor spaces, but with a little extra care, you can overwinter them inside and move them back outdoors in spring. Mandevillas are no exception! Even tropical trees, including fruit trees, can tolerate a few months indoors if given the right conditions for semi-dormancy. Below are the 10 key tips for successfully overwintering tropical plants indoors.

1. Maximize Light: The more light, the better. There's no such thing as too much indoor light. If windows aren't enough, use LED grow lights, which stay cool and won't dry the air. Rotate plants every few days to prevent uneven leaf loss.

2. Reduce Watering: Less light and cooler temperatures mean plants need less water. Allow the soil to dry between waterings, and avoid overwatering - combination of cold + wet is especially harmful.

3. Maintain Moderate Temperatures: Most tropicals are happy with daytime temperatures around 75F and nights at 50-60F. In sunrooms or greenhouses, some can handle 45F if watering is kept to a minimum.

4. Boost Humidity: Avoid placing plants near heaters or vents that dry the air. Misting daily helps, or place pots on trays filled with water and pebbles to raise humidity around them.

5. Monitor for Pests: Check leaves weekly to catch insect problems early, as pests can cause serious damage or even kill the plant indoors.

6. Fertilize Smart: Use ONLY liquid, amino-acid-based fertilizers like Sunshine Boosters throughout winter; they won't burn roots since their dosage adjusts with reduced watering. Avoid dry, granulated, and EDTA-based fertilizers during winter and dormancy.

7. Use Micro-Nutrients: Along with macro-elements (fertilizers), supplement with micro-elements like Sunshine Superfood and bio-stimulants such as Sunshine Epi to build strong plants with robust immune systems, better able to withstand unfavorable conditions and resist diseases.

8. Hold Off on Pruning: Leaf drop and leggy growth are normal responses to winter. Wait until spring to prune, when new growth starts, to encourage branching and healthy foliage.

9. Don't Repot Yet: During dormancy, roots slow their growth. Repotting too soon risks root rot. Wait until spring when new growth appears to transplant into a larger container. Typically, roots grow in proportion to the above-ground parts.

10. Let Them Rest: Winter is a natural resting period. Avoid forcing growth - your plants will reward your patience with vibrant leaves and flowers when spring returns.

Q: Are there any tropical plants that will do well if I order them in Winter? We just bought a house in New Jersey with a large sunroom, and I can't wait to fill it with tropical beauties! Should I wait until Spring, or do you have something for a Winter start?

A: This is indeed a very good question, as many tropical plant collectors grow their treasures outside the tropics. The short answer is - yes! You can start filling your tropical sunroom any time of the year, but some plants are easier to deal with in Winter than others. Below are some guidelines.

Winter bloomers today, left to right: Jatropha, Champaka, Brunfelsia, Calliandra, Leonotis.

1. Plants that prefer Winter shipping to avoid overheating stress:
- All plants with lush foliage such as Philodendrons, Medinilla
- Trees with fine feathery leaves such as Moringa, Jacaranda, Poinciana
- Some fruit trees sensitive to overheating during shipping: Papaya, Stawberry Tree, Starfruit (Carambola), Bilimbi.

2. Subtropical plants that are relatively cold hardy
- Fruit trees: Loquats, Olives, Avocados, Tropical Cherries: Eugenia, Malpighia, Noni (more cold hardy than you may think), Canistel.

6. Winter plant care. During Winter the daylight is shorter and temperatures are cooler.
- Reduce watering
- Use only liquid amino-acid based fertilizer Sunshine Boosters (safe to use year around)
- Monitor insects.

7. Shipping in Winter. We ship year around. However, if it gets below freezing in your area, you may use FedEx Hold location, they are temperature controlled so you don't have to worry about a box being dropped off at your cold porch outside.

8. A note for mild climate residents. Most tropical plants can be planted in the ground year around. Some ultra-tropical tender species such Chocolate tree, Ylang Ylang, or small size Mango trees can be grown in pots until Spring and planted out once chances of cold spell are gone. Until then, they can be moved indoors for cold nights.

Think outside the box and bring tropical paradise indoors during the time when we need warmth the most! Tropical plants will brighten your short winter days and help you to have truly HAPPY HOLIDAYS!
