How to grow Jackfruit in a pot:
the biggest fruit in the world

Jackfruit - Artocarpus heterophyllus

Q: Can I grow Jackfruit in a pot?

A: Yes, you can! Jackfruit trees, despite producing the largest tree-borne fruit in the world - up to 80 pounds and 36 inches long - can thrive and fruit in containers. The tree has a clever feature: it grows fruit only at the base of the trunk, allowing you to manage its height and size. With regular pruning, the tree can stay compact at just 6-7 feet tall, making it perfect for pot culture.

1. Getting started: pot sizes and growth tips

Start with: A 3-7 gallon container.
As it grows: Gradually increase to a 15-25 gallon pot by the time it reaches fruiting size (2-4 years).
Pruning is key: Keep the tree topped at 6-7 feet to focus its energy on fruit production.
Fertilize regularly: Use high-quality plant food like Sunshine Boosters C-Cibus to promote healthy growth and fruit development. C-Cibus is the best natural plant food for fruit and edibles.

2. Fun facts about Jackfruit - Artocarpus heterophyllus

Jackfruit - Artocarpus heterophyllus

A mature Jackfruit tree can produce 200 pounds of fruit per year.
The fruit consists of large, sweet, yellow bulbs with a banana-like aroma.
Seedlings start fruiting within 3-4 years, with fruits ripening in just 4-6 months after flowering.

3. Cold tolerance of Jackfruit trees

Though often thought of as ultra-tropical, mature trees can withstand light frost for short periods without major damage. Keeping Jackfruit in pots also offers an easy way to move them indoors during cold spells if you're in a cooler climate.

4. Secrets for successful Jackfruit production

- Frost-free temperatures are essential.
- Use rich, organic soil with compost, manure, or peat moss.
- Maintain moist soil with regular watering.
- Constant pruning to keep the tree under 7 feet promotes healthy fruiting.
- Apply fertilizer and microelements regularly for better fruit quality.

By following these tips, you'll be able to enjoy the world's biggest fruit right from your patio!

How to propagate plants from cuttings. Top (Tropicals) secrets.

TopTropicals.com

Q: After pruning my jasmine, I have so many branches and I don't have a heart to through them away, can I use them to make more plants? Please tell me what size cuttings and do I need to remove leaves? Should I just stick them in the ground? Will they root? I don't know if you will be willing to share your secrets?

A: We are always happy to know that you grow more plants, and make our World better! These are some useful tips for the propagation of tropical plants using cuttings:

- Cuttings and leaves. Use cuttings 2-5" long. Strip leaves from the bottom. Cut larger leaves in half to reduce evaporation.
- Soak cuttings for 15-30 min in SUNSHINE solution.
- Mix. Use special well-drained mix with lots of soil conditioner: we have a special professional propagation mix for cuttings.
- Mist. Put community pots or trays with cuttings in mist, or if you don't have mist - cover the pot with a clear plastic bag to create a mini-greenhouse.
- Shade. Keep propagation pots in bright shade and never allow direct sun rays.
- Rooting hormone: yes, use it if you have it. Not only it promotes root formation but also prevents from fungus so the cuttings won't rot. We use Dip-N-Grow.
- Rooting and food. Check in 2-3 weeks for roots. Once you see the little roots, begin fertilizing with a special Baby-Plant Food and make sure never exceed recommended doze otherwise you may kill the cuttings.
- Establishing. Once roots start growing, plant in 4" pots in a well-drained potting mix and watch the beauty grow! Gradually move to the full sun only when little plants establish and start new growth.

If you are lucky to make more rare plants than you can use, contact us, we will buy them from you or trade for your dream plants! In fact, one of our customers from many years ago started selling us baby plants that he propagated from our plants, and now has a successful business (Karma Nursery); we buy a lot of plants from him every month!

Growing Barbados Cherry in container

Barbados Cherry fruit on the branch

Q: I am interested in buying some Barbados cherry plants. Could you please advise if these can be grown in containers indefinitely or it's still better for them to be planted in ground for nutrients etc?

A: The Barbados cherry, like other tropical cherry varieties, is exceptionally well-suited for cultivation in containers.

Barbados cherry grows into a dense bush, demands minimal pruning, and begins bearing fruit at a young age. Our plants, which are propagated from cuttings, initiate the flowering and fruiting process in the very same year. They produce fruit almost year around. This year we've had three big crops: April, July and October (still fruiting now!) besides sporadic fruiting throughout the warm season.

You can cultivate Barbados cherry in a pot, commencing with a 1-3 gallon container and gradually increasing the size each year. Below is a photo of a fully developed tree in the ground, for reference. This tree is approaching its third year of growth. When grown in a container, it maintains a more compact size, with the largest container needed likely being between 7 to 15 gallons. Regular pruning can be employed to keep it smaller.

Barbados cherry (Malpighia) possesses a distinct growth pattern that sets it apart from other tropical cherry varieties - Eugenias. Malpighia's branches can assume peculiar shapes, even at angles of up to 90 degrees. Therefore, pruning to achieve the desired shape is advantageous.

Additionally, you may want to explore the Dwarf Barbados cherry, a miniature cherry variety ideal for container cultivation, with cascading growth habit. Although its fruits are slightly smaller than those of the regular variety, they are notably sweeter.

When it comes to ensuring the health and vitality of your potted Barbados cherry plants, maintaining a consistent nutrient supply is crucial. Implementing a regular fertilization regimen is essential to promote robust growth, consistent flowering, and bountiful fruit production. For optimal results, we recommend using Sunshine Boosters, which are specially formulated to enhance the development of fruits and edibles. These boosters are derived from organic amino acids, making them environmentally friendly and safe for year-round use. By incorporating Sunshine Boosters C-Cibus into your plant care routine, you can ensure that your container-grown Barbados cherry plants receive the essential nutrients they need to thrive and flourish.

URBAN TROPICAL GARDENING:
10 secrets of successful Container Mango growing on a balcony.

Q: I live in Miami in apartment on a second floor, and I have a balcony with SE exposure. I wonder if I can grow a mango tree in a pot? Will it fruit for me? I recently moved to South Florida and I don't know much about tropical plants; but I tasted real fiberless mangos from someone's garden - it was so delicious and different from those in the grocery store. I wonder if I can have a fruiting tree on my balcony? And if yes, how do I plant and take care of it?

A: Yes, you can! Here is what you need to do:
1) Temperature. You are lucky to live in Tropics, keep it on a balcony year round.
2) Light. Position the pot in a spot with the most sun exposure. Mango trees can take filtered light too, but the less sun, the less fruit you will get.
3) Soil and Container. Use only well drained potting mix. Step up the purchased plant into next size container (3 gal into 7 gal, 7 gal into 15 gal). When transplanting, make sure to keep growth point (where roots meet the trunk) just at the top of the soil. Covering base of the trunk with soil may kill the plant.
4) Water. Water daily during hot season, but only if top of soil gets dry. If it still moist, skip that day. Mangoes (unlike Avocados!) prefer to stay on a dry side.
5) Fertilizer. Use balanced fertilizer once a month, 1 tsp per 1 gal of soil. Do not fertilize during fruiting - this may cause fruit cracks.
6) Microelements. Apply SUNSHINE-Superfood once a month. This will help your mango healthy, vigorous, and resistant to diseases. Use SUNSHINE-Honey to make your fruit sweeter.
7) Insect control. Watch for scales and mealybugs, clean with solution of soapy water + vegetable oil (may need to repeat 2-3 times with 10 days interval), or with systemic insecticide like imidacloprid only as needed (if non-harsh treatment didn't help). Most Flea shampoo for dogs contain that chemical, you may try that shampoo solution.
8) Trimming. Once potted, do not remove leaves that are discolored or have spots until new growth appears. Dark dots on mango leaves, especially in humid climate like Florida, may be signs of fungus. Treat with fungicide according to label, and remove only badly damaged leaves. Trim crown as needed after flowering and fruiting (by Fall). Train into a small tree, and you may remove some lower branches eventually.
9) Flower and fruit. Mangoes are winter bloomers with bunches of tiny flowers coming in thousands. Many of them set fruit (if pollinating insects present). Keep in mind that young trees can only bare a few fruit. Normally a tree will drop excessive fruit and keep only a few that it can manage. To save the young tree some energy, remove fruit if too many and leave only 2-3 for the first year. It will pay you next year with more abundant crop.
10) Variety. Last but not least: Choose the right variety for container culture! Pick from "condo" dwarf varieties such as Icecream, Nam Doc Mai, Carrie, Cogshall, Julie, Fairchild, Pickering, Graham, Mallika, and a few others - check out Mango Chart pdf and full list of our Mango varieties.

How to feed a Mango tree...
and to grow a Dwarf Mango

How to fertilize a Mango tree

Q: My mango trees that I bought and planted last august now have fruit. I bought 2 types of fertilizer from you and never used it. Should I use your fertilizer now?

A: It is a perfect time now to fertilize your plants as they start active growth. For mango trees, we recommend liquid fertilizer Sunshine Booster - Mango Tango. It is formulated for Mango trees, especially for container grown. It improves quantity and quality of flowers and ability to set fruit, reduces bud-flower-fruit drop. Can be used as often as with every watering. For best results, use in combination with Sunshine Honey and Sunshine Superfood plant supplements. Its scientifically-balanced stable formula is organic Amino-acid based and has NO EDTA chelators to eliminate nutrients lockup; it does not affect crop taste.
Additionally, you may use slow-release granulated fertilizer Mango-Food once a month during hot season only. Dosage: 1 teaspoon per each gal of soil. Water-soluble fertilizers can be also used, however, those are usually EDTA-chelated which is not as efficient as Amono-acid based Sunshine Boosters and may create nutrients build up, especially if overdosed in containers.
For in-ground mango trees, you may use all the above, and slow-release granulated fertilizer can be applied in larger quantities: spread a handful around the drip line.

Remember that only liquid Sunshine Boosters can be applied year around. With other fertilizers, you need to be careful not to overdose, and apply only during hot weather (when night temperatures are steadily above 65F).

How to grow a Dwarf Mango tree

Q: I received the Ice cream mango tree in great condition (thank you for the ingenious packing job) on Wednesday and have planted it in a pot slightly bigger than the root ball. I plan to grow the tree on my front porch, so how big a container should I ultimately use when the tree outgrows this pot? How big a container does it need to fruit? I hope to keep it around 6-7 feet high, if possible. I live in Hawaii.

A: Ice Cream mango is a perfect variety for container culture, and it should be happy in Hawaii. You did everything right. Keep it in this small pot for now and wait until it starts vigorous growth in Summer. Once it starts growing (and you will notice roots growing too, sometimes they try to grow through the holes in the bottom of the pot), then it's time to step up into a bigger container (7-10 gal). Eventually you may use container size as large as 15 gal. Ice cream mango is slow growing and compact, and you will be able to maintain it under 7 ft with very minimal pruning if any.
