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!

Cocoa plant after winter

TopTropicals.com

Q: I purchased the Theobroma cacao two months ago. The leaves are wilting from the edges. Do you think this from not enough water, too much water or not enough sunlight? I am keeping the plant indoors.

A: During winter time, Cocoa plants even inside our greenhouse look the same. Dry tips of the leaves are normal for this time of the year. It is a combination of lower temperatures and low humidity that causes it. Indoors air humidity is especially low. Weather permitting, bring plant outside in the bright shade, when temperatures are above 65F. Humidifier and water-spraying will help too. You may put the plant on top of a tray with pebbles/water. Do not overwater - extra watering is not a substitute for high humidity. As spring comes, Cocoa plants start looking greener and grow new healthy leaves.

🎄 Do not throw out your poinsettia - 4 simple tips how to keep it alive for next Christmas



Poinsettias - Euphorbia_pulcherrima - are tender perennials, not one-season plants. After the holidays they naturally fade, rest, and regroup. With a few simple care tweaks, a healthy plant can live all year and rebloom next winter.
  • 🎄 1. Let it rest after the holidays


  • ✦ Flowering ends naturally - faded bracts and some leaf drop are normal.
  • ✦ Prune when bracts fall: cut stems back by 1/3 to 1/2, leaving 4-5 inches.
  • ✦ Wear gloves - the sap can irritate skin.
  • ✦ Move to a cooler, bright spot for 4-6 weeks.
  • ✦ Ideal temp: 55-60°F
  • ✦ Reduce watering.
  • ✦ Water only when the top 2 inches of soil are dry.
  • ✦ Avoid soggy soil.


🎄 2. Repot in late spring

  • ✦ New growth usually starts in late spring.
  • ✦ Repot at this stage to refresh nutrients and give roots space.
  • ✦ Use a well-draining, slightly acidic potting mix.
  • ✦ Choose a pot only slightly larger, with drainage holes.
  • ✦ Loosen roots gently and remove old compacted soil.
  • ✦ Water lightly, then place in a bright, warm spot.
  • ✦ Resume regular watering and light feeding through spring and summer.


🎄 3. Adjust care during the growing season

  • ✦ Increase temperature gradually to 64-68°F.
  • ✦ Water more often once growth resumes.
  • ✦ Wilted or curling leaves signal thirst.
  • ✦ Water thoroughly and evenly.
  • ✦ Bright light is key, but avoid harsh direct sun.
  • ✦ Use sheer curtains or a grow light if needed.
  • ✦ Fertilize periodically with a balanced houseplant fertilizer.
  • ✦ Pinch back new shoots in late spring for a fuller, bushier plant.


🎄 4. Preparing for winter color

  • ✦ In fall, poinsettias need long nights to bloom.
  • ✦ Provide 12-14 hours of complete darkness nightly for 6-8 weeks.
  • ✦ This triggers colorful bracts in time for the holidays.


❓ Quick FAQ



Can it go outside?
Yes, in warm months only. Bring it indoors before temps drop below 50°F.

Winter outdoors?
No - poinsettias are cold-sensitive and must stay inside.

🎄 Poinsettias don't die after Christmas - they just take a nap. Give them rest, light, and patience, and they will reward you next year.

🌺 How to grow Mandevilla: Practical Guide to Growing Mandevilla Vine

  • 🌺 Mandevilla is a tropical vine known for its vibrant, trumpet-shaped flowers that bloom throughout the warm months. This fast-growing climber thrives in warm climates and adds a stunning display of color to gardens and patios.
  • 🌺 Difference Between Mandevilla and Dipladenia


    The names Mandevilla and Dipladenia are often used interchangeably, creating confusion. While they are closely related, there are key differences. Mandevilla is a vigorous woody vine with large, stiff leaves, ideal for trellises and fences. Dipladenia, on the other hand, has a more compact growth habit with smaller, smooth leaves. Dipladenia can be also trained on a trellis but also thrives in hanging baskets or as a compact specimen plant. As a bushier type of Mandevilla, its smaller, more compact varieties are excellent for mixed containers.
  • 🌺 Growing in the Ground


💋Soil. Mandevilla prefers well-draining soil enriched with organic matter. A mix of garden soil, compost, and sand ensures good drainage and fertility. Both Mandevilla and Dipladenia require acidic soil. If your native soil contains limestone, consider growing them in containers with a peat-based potting mix to maintain a lower pH.
  • 💋Light. Plant in a location with full sun to partial shade; at least 6 hours of direct sunlight promotes the best blooms.
  • Water Mandevilla regularly, keeping the soil moist but not soggy. During hot months, water deeply a few times a week. Reduce watering in cooler seasons.
  • 💋Feeding and Encouraging More Blooms: Feed Mandevilla with Sunshine Boosters Megaflor with every watering to encourage more blooms. Prune lightly after flowering to promote new growth and continuous flowering.

  • 🌺 Most Interesting Varieties
  • Mandevilla flowers come in a wide range of colors, including shades of red, mauve, pink, white, and even yellow. For vibrant color and impact, consider these varieties:

💋Mandevilla ‘Alice du Pont’– A classic pink variety with large flowers and vigorous growth.
  • 💋Mandevilla ‘Sun Parasol’ Series – Offers compact plants in deep red, pink, or white, great for containers or small spaces.
  • 💋Mandevilla ‘Crimson Red’– Deep red blooms stand out against glossy green foliage.
  • 💋Dipladenia ‘Stars and Stripes’ - features striking red-and-white striped blooms.
  • In Florida, Sun Parasol and Alice du Pont perform exceptionally well, thriving in the heat and humidity while providing season-long blooms.

  • 🌺 Pests and Problems
Mandevilla is relatively pest-resistant but can attract aphids, spider mites, and whiteflies. To manage pests:
  • 💋Spray with a neem oil solution weekly if pests are present.
  • 💋Encourage beneficial insects like ladybugs to control aphids naturally.
  • 💋Remove affected leaves and rinse plants with a strong stream of water.
  • 💋Watch for fungal diseases in humid climates; ensure good air circulation and avoid overhead watering.


🌺 Growing Mandevilla in Pots and Winter Care


Mandevilla grows beautifully in containers, making it a great option for cooler climates where it can be brought indoors for winter.
  • 💋Pot Growing Tips:

· Use a well-draining potting mix with added perlite for aeration.
  • · Choose a pot at least 12-16 inches in diameter, with several drainage holes, for vigorous growth.
  • · Water when the top inch of soil feels dry, avoiding waterlogged conditions.


💋Winter Care:
  • · In regions with frost, move potted Mandevilla indoors to a bright, cool location (50-60°F).
  • · Reduce watering and stop fertilizing during cooler season.
  • · Prune lightly before bringing indoors to maintain shape and size.
  • · Repotting: Repot every 2-3 years in early spring before active growth begins, refreshing the soil and upgrading to a slightly larger container if needed.

With the right care, Mandevilla provides stunning, long-lasting blooms and thrives in gardens or pots, making it a versatile and rewarding addition to any space.

✍️ From seed to fruit. How to grow Loquat from seeds, step-by-step guide. Part 2: after germination



Continued from previous posts⤴️
  • 🍑 4. Transplanting Seedlings


  • When to Transplant: Once seedlings reach about 2-4” (5-10 cm) in height.
  • Transplanting and fertilizing: Move each seedling to its own pot and add controlled release fertilizer (Green Magic is the best), or use liquid balanced fertilizer Sunshine Boosters after 1-2 weeks once the seedlings establish.
  • Watering. Keep soil in a pot slightly moist but not soggy
  • Temperature. Keep seedling warm - above 70F (21C), and protect from extreme heat over 90F (35C) . For small plants, avoid freezing temperatures during winter. As the seedlings get bigger, they get higher drought-, heat- and cold tolerance. Established Loquat trees (2-3 years and older) may take light freezing temperatures.
  • Planting in the ground. You can plant the seedling in the ground when it reaches 2-3 ft tall (50-100 cm) in frost-free areas. During chill winter nights, young seedlings can be cold protected until established.


🍑 5. Sunlight Requirements

  • Light Exposure: Loquat established seedlings thrive in full sun but can tolerate partial shade. Start seedlings in bright shade and protect from afternoon hot sun to avoid leaf burn. Once seedlings are established and new growth appears (2-4 weeks), gradually move them to full sun.
  • Why adequate sunlight (full sun) is important:
- promotes healthy growth
- helps to avoid fungus and insect problems
- is critical for future flowering and fruit production

🍑 6. Fruit production

  • Loquat seedlings start producing seed within 3-4 years from seed, providing adequate sunlight, warm temperatures and regular irrigation.
  • Grafted Loquats start producing right away or the next year
  • Fruit will develop over the winter and ripen from March through May depending on location
