Cold hardy tropical fruit trees for Zone 9

Q: Can you suggest tropical fruit that can be grown (cold hardy) in Zone 9?

A: There are quite a few tropical/subtropical trees that will grow well in zone 9. Our favorites are: Figs - very cold hardy and drought tolerant.
Loquats - grafted trees that start fruiting right away, reliable producers.
Tropical Mulberry - very fast growing trees that can take freeze, heavy producers.
Macadamia - these trees are of a compact nature, very easy to grow and start producing nuts right away.
Many different varieties of Eugenias - tropical cherries - all-time favorites. Another tropical cherry - Malpighia, or Barbados cherry - starts fruiting in small size under one food tall! Great for containers.
Tropical (Low Chill) Peaches, Nectarines, and Plums. See full list of low-chill, relatively cold hardy fruit trees.
And of course - Bananas!

Don't forget to fertilize your fruit trees to improve their cold hardiness!

The most rewarding hardy fruit trees

Q: Recently I started working remotely and I kinda like it, no need to commute, it saves me so much time so I can have life now! My friend got me involved into growing some small houseplants but I really want to take advantage of our Florida climate and sun. I want to plant some cool fruit trees since I have a decent size yard. But I live in Florida Panhandle and we do have some occasional freeze in winter, although not for too long. But it gets very hot in summer! Are there any tropical fruit trees that will be happy here? Or should I keep everything in pots? I am excited to have my own tropical plant collection!

A: There is a perfect plant for everyone, and a perfect tree for every climate. Many tropical and especially subtropical plants can be much hardier than they are believed to be, both flowering and fruiting trees among them. You may keep the most sensitive species in pots and bring them inside for winter, while there are so many trees that will be happy in your area. Start with these that are perfect for climates with hot summers and cool winters:

1. Peaches and Plums

Low-chill, Heat-tolerant Peaches, Nectarines, Plums are especially selected for Florida hot summers. They produce well and do not require many "chill" hours like temperate fruit trees. They only need 150 chill hours and grow well in even in Arizona, so you know they are taking the heat.

2. Figs

2) Fig trees - they are easy to grow, heat- and drought- resistant trees. They are prized for their delicious fruit, which can be one to three inches in length, violet, brown or black. There are even varieties with yellow fruit. Most fruits are borne from early summer to late fall on new growth, and the fruits generally mature very quickly. These trees are sensitive to frost only when actively growing, but can withstand 10F when dormant. Read more about Fig trees.

Alstonia scolaris - Indian Devil Tree

A Scholar's Award with intoxicating fragrance

By Alex Butova, the Witch of Herbs and Cats

...This fascinating rare plant with white, strongly perfumed flowers is valued as a fast growing, impressive ornamental shade tree and is used to serve as an alternative to quinine...
Popularly known as Devil Tree, as plant is believed to the devil's abode - probably due to the intoxicating fragrance emitted by flowering trees, especially at night.
The tree is of great cultural significance in the intellectual circle, as traditionally its leaves were awarded to scholars and teachers during convocation ceremonies by the Visva Bharati University (can't think of a better name than Alstonia scholaris!). This tradition was started by Rabindranath Tagore...

The truth about Sensational Monstera Thai Constellation

"Nothing's making sense anymore. It's gotten out of control"

Painting above: "Thai Constellation Monstera deliciosa" with acrylic paint on textured background by Audrey Ehlinger - participant of the 2020 Tropical Plant Art Contest

Variegated Monstera... Now that this Sensational plant deserves even its own works of art, it is time to admit: this beauty is probably one of the most surprising phenomena in the history of rare plant industry.

Many plant collectors noticed the craziness around this unusual variegated cultivar of Monstera deliciosa - Thai Constellatio. Top Tropicals was the first plant nursery that originally introduced this variety into the US tropical plant market a few years ago. Since then, popularity of this plant went above and beyond any expectations. Everybody wants this plant! Yet it is nearly impossible to propagate, with the only somewhat successful method as Tissue Culture. Besides, in order to create a viable batch, one must use cells from the stem only. Considering this plant grows about 2 inches a year (in favorable conditions), this leaves us with very limited propagation material... Who can sacrifice their unique mature plant for a knife of a propagator? Let us know if you have any extra you can share ;)

No wonder very quickly Thai Constellation had become a commodity plant, or even better - an asset compared by some people to a real estate bubble... Some collectors sell cuttings for $2,000 each. People pay up to $250 per leaf of this plant... Crazy? Maybe. But being rare plant collectors, we all know the feeling! Check out this article:

It's Better Than The Stock Market: A Massive Bubble Is Forming In The Rare Plant Market...

Thai Constellation available for sale:

The good news is - we have a few plants. They are in 4"pots. Small, but well-established. The price is not cheap. It is what it is - this is what it costs us to obtain these plants from Thailand. This is the last batch for a long while, no more available even at this price, since the growers can't find enough propagation material to satisfy the market. Next batch expected from tissue culture is probably 2022. We have over 400 customers on wish list for this plant.If you really NEED IT, order right now!

Healthy Plant Food

Q&A from Mr Booster

Plant food for a Star Fruit

Q: I have 2 Starfruit plants from you. One on the left is B10 has a lot of flowers but no fruit is developing. On the rite is Kenjeng. This one has no flowers at all. Both plants are growing very well. Plenty of sun and water. I am located in Boynton Beach Florida. So what to do?

A: Your trees on the pictures look very healthy, congratulations with a great care!
Starfruit, as well as other grafted fruit trees (like mango, avocado, etc) usually flower/fruit easily and readily while in pots in the nursery. Sometimes, once planted in the ground, they may reduce flowering or even stop flowering. What happened?
The answer is simple. In pots, we fertilize them on regular basis. In our nursery, we have fertilizer injector inline with irrigation system that dozes plant food with EVERY watering. In other nurseries, they may also use slow-release fertilizers, but it is still a regular routine to provide plant food to potted plants.
In the ground, especially in Florida poor soils, fruit trees may stop flowering or delay fruiting due to lack of nutrients, or dis-balance of elements in the ground. Without fertilizer, a tree may take extra time to develop bigger root system to reach out for necessary elements, and eventually will start fruiting anyway.
But we want it to fruit soon! The only way to fix the problem is to provide fertilizer on regular basis for a young tree. It is especially important during hot summer months when plant metabolism is fast due to high temperatures, plus nutrients may get washed away with frequent summer rains (like we have in Florida) even if you've added some fertilizer at time of planting.

You can use smart release fertilizer once a month during hot season, this one or similar:
Mango-Food - Smart Release Fruit Tree Booster.

But the most effective way to get a tropical tree to flowering and fruiting, is frequent applications of liquid fertilizer. We use Sunshine Boosters with every watering on our plants. They work great even on hard cases and weak plants, and you see the difference in a matter of weeks, sometimes even days.
We recommend the following fertilizer that contains all necessary elements for young fruit trees: SUNSHINE C-Cibus - Crop Nutrition Booster

SUNSHINE C-Cibus - Crop Nutrition Booster from Garden Series, or Combo Total Feed Collection - all nutrients in just one bottle, for fruit trees and edibles.
