How to get Canistel tree to produce
without dropping flowers and fruit

Q: My Canistel tree is 3 1/2 years old and is growing very well, see the picture below. It gets hundreds of pea sized "berries" but then they fall off. No canistel fruit. What's wrong?

A: You have such a nice looking tree, it is a shame you can't get any fruit to ripen.
In our experience, Pouteria trees dropping fruit prematurely is a very common problem. There may be one of the following reasons, or a combination of them:
- Cold winters may affect production, and while Canistel is generally pretty hardy tropical plant that can easily withstand short periods of chill, the fruit may never form properly if it had a cold winter.
- Lack of water. Canistel tree is pretty drought tolerant, but for the proper production cycle it needs regular irrigation. Especially during hot summer.
- The tree may be not strong enough; young trees drop fruit very often when they don't have enough "fruiting energy" built up in their system.
Your tree looks well established and vigorous, however, flower/fruit drop is often a sign of insufficient nutrients of particular kind, usually Boron (B) and/or Molybdenum (Mo): either when a tree is too young and not strong enough, or because of poor soils and lack of necessary elements.

Here is what can be done, considering you live in a warm, frost-free climate.

1. Provide regular fertilizing program. We recommend liquid fertilizers Sunshine Boosters that are safe to use with every watering and year around. It is beneficial to switch plants from traditional "slow-release" fertilizer to the liquid one because it makes a huge difference in plant growth and flower/fruit quality and quantity. See also:

2. Apply micro-element remedies that are very effective for improving fruit production, especially when flower or fruit drop occurs:

SUNSHINE Honey - promotes more efficient blossoming and pollination, makes flowers bigger and reduces bud drop.
SUNSHINE SuperFood - improves plant vigor and quality and size of flowers These are all natural, eco-friendly supplements that work great for fruit trees and other edibles.

Mulberry Care and Growing Tips

Mulberries are tough, low-maintenance fruit trees that adapt to many conditions.

• Climate: Hardy from USDA zone 5 to 10.
• Soil: Grow well in almost any soil; prefer good drainage.
• Watering: Regular watering during dry spells; drought tolerant once etablished.
• Growth: 3–5 feet per year, producing fruit early.
• Pruning: Annual pruning controls size and improves branching.
• Pot culture: Dwarf types thrive in containers, staying 6–7 feet tall. Use a large pot, water consistently, and prune lightly. Use Abundance potting mix for best results.
• Fertilizer: For reliable production, fertilizer regularly. Apply Sunshine C-Cibus liquid booster with every watering, or Green Magic controlled release fertilizer every 5-6 months.

⭐ The Winter Stars: 8 Flowering Trees That Steal the Show

8 Best Flowering Trees That Bloom in Winter: Royal Poinciana with red-orange canopy, Dwarf Pink Tabebuia, Dwarf Golden Tabebuia, Pink Butterfly Orchid Tree, Golden Rain Tree, Weeping Red Bottlebrush, Hong Kong Orchid Tree, and Jacaranda with purple flowers.

Royal Poinciana (Delonix regia)

The diva of tropical trees. Huge red-orange flowers blanket the branches from late winter through summer. If you’ve ever seen one in full bloom, you know — it stops traffic. Best in large yards or open spaces, but young ones do great in big pots for a few years. 🛒 Shop
Tatiana: “If you want a tree that makes people say ‘wow,’ this is it.”

Tabebuia chrysotricha – Dwarf Golden Tabebuia

Small tree, big drama. It turns solid gold just before new leaves appear. Blooms while completely bare — a stunning contrast of yellow on brown wood. Perfect for patios, courtyards, and containers. Handles cool nights down to the mid-20s F. Bright, cheerful, and forgiving — the kind of tree that always looks like it’s celebrating. 🛒 Shop

Tabebuia impetiginosa – Dwarf Pink Tabebuia (Pau D’Arco)

The Florida “cherry blossom.” Pink-lavender flowers smother the branches each winter, often before any leaves return. Thrives in sandy soil, tolerates drought, and grows beautifully in large planters or pots indoors near a sunny window. Ideal for seasonal residents or anyone who wants color when everything else is asleep. 🛒 Shop

Jacaranda mimosifolia

If color had music, this would be jazz. Soft, fern-like leaves and cascades of violet-blue trumpet flowers — airy, elegant, unforgettable. Outdoors, it makes a graceful shade tree; in containers, it stays compact with regular pruning. Jacarandas reward patience — they bloom bigger each year. 🛒 Shop

Koelreuteria paniculata – Golden Rain Tree

A favorite for its surprises — golden blooms in summer, pink paper lantern pods in fall, and bronze leaves before rest. Fast-growing, tough, and easy. Loves full sun and moderate water. Great for open lawns or patio tubs. The kind of tree that gives you something new to look at every month. 🛒 Shop

Callistemon citrinus – Bottlebrush Tree

The hummingbird magnet. Bright red, brush-shaped flowers bloom several times a year — sometimes even in cool weather. The dwarf form, ‘Little John,’ stays about 4 feet tall, perfect for pots or small borders. Trim lightly after flowering to keep it compact and colorful. 🛒 Shop
Tatiana: “If you’ve never grown a tropical tree before — start here. It’s the friendliest one.”

Bauhinia variegata – Pink Butterfly Tree

Graceful, fragrant, and forgiving. Its pink-lavender orchid-like flowers open from late winter through spring, filling the garden with color and pollinators. It’s fast-growing, drought-tolerant, and excellent for both ground and pots. Even the buds are edible — a fun bonus for adventurous gardeners. 🛒 Shop

Bauhinia blakeana – Hong Kong Orchid Tree

The queen of them all. Huge magenta-purple blooms that last for months, from fall through spring. Fragrant, clean (no messy seed pods), and perfect for patios or large decorative containers. Give it sun, a little water, and it will reward you with bloom after bloom. 🛒 Shop
Tatiana: “It’s the one tree that never lets winter win.”

A note on grafted Hong Kong Orchid Trees: Most Hong Kong Orchid Trees are grafted, and that’s actually a big advantage. Because they don’t grow from seed, grafted plants mature faster and begin blooming while still small — sometimes within the first year. That makes them perfect for patio pots or small gardens where space is limited.

Bringing the Tropics Home

Whether your garden faces the Gulf or your window faces the snow, these trees let you live in color year-round. Plant them outdoors in warm zones or grow them in pots indoors — they adapt, they bloom, they brighten every corner.

Gardening isn’t about waiting for spring — it’s about finding joy in every season. And when a tree blooms in January, that joy feels twice as sweet.

✍️ Winter Bloomer Q&A

Q: Can these trees really bloom indoors?

Yes! Smaller species like Bottlebrush ‘Little John,’ Dwarf Tabebuias, and many Bauhinias bloom beautifully in pots with bright light or grow lamps.

Q: Do they lose their leaves in winter?

Some, like Tabebuias and Jacarandas, drop leaves right before blooming — it’s normal and part of their charm. Others, like Bottlebrush, stay evergreen.

Q: What fertilizer works best?

We use Sunshine Boosters — gentle, balanced, and perfect for tropicals. Feed every 2–3 weeks during active growth.

Q: How do I know when to water?

Touch the soil! If it’s dry an inch or two down, water deeply. Overwatering is the main mistake with tropicals.

Q: Can they handle frost?

A quick dip into the upper 20s F is fine for most mature trees. Cover young ones or move containers under shelter if colder.

Q: Which are best for beginners?

Start with Bottlebrush ‘Little John’ or Golden Tabebuia — compact, colorful, and nearly foolproof.

Q: When will they bloom?

Usually within few years if they get enough sun and warmth. Grafted plants blooms much sooner

Q: Which of these trees are best for pot growing?

For patios, balconies, or indoor sunrooms, choose the compact or grafted types:
