Growing Stephanotis and cold protection

Q: I bought from you 3 plants Stephanotis How do I protect them from this low temperature now? I live in Ft Myers Beach.

A: In Ft Myers Beach, you have frost-free winters. You don't have to worry about cold protection for the Stephanotis. It is pretty cold hardy plant in spite of being a true tropical (it enjoys Hawaii environment for example). From our own experience, Stephanotis can even take a light frost for a short period of time without any damage.
You can keep this plant either in a pot or plant in the ground in a nice sunny location for more profuse flowering. It can climb a tree, a fence, or a pagoda.
However, keep in mind that during cool weather you need to reduce amount of watering. Wet + cold is a bad combination for plants. Water again only when the soil gets slightly dry. In summer time, extra water is not critical because it evaporates quickly with high temperatures.

Mango ID and ripeness

Q: As the World's Leading Authority on Tropical Plants, I hope you can help us out. We obtained a mango tree from a City giveaway, and planted it a few years ago. This is the 1st year it has produced fruit. They are almost all green color, & range from 6-7 inches in length. Attached are a few photos of the tree & its fruit. Please help to identify the type, and how to determine when they would be ready to pick. Or should we just wait until they fall off of the tree?

A: If the tree is grafted, it normally starts flowering within a year after planting. If the tree is over 6 years old and just now started fruiting - chances are, this is a seedling (possible at giveaways) without specific variety. However the fruit looks pretty good size and shape, hopefully it tastes great. You will find out soon!
Based on the pictures, there maybe a few possible choices, including varieties (or their seedlings) Keitt, Rosigold, it can be even Lancetilla if fruit grows bigger than 7" long. The next step would be, wait until the fruit get some color, then it will be easier to narrow down the variety. Also see if there is a lot of fiber or no fiber.
You may wait until at least one fruit ripens on the tree and let it fall naturally - that will be the color (can be all green, but in your case it looks like it's turning yellow blush). After that, you may pick full size fruit before they fall and let them ripen on a kitchen table. Usually once the fruit starts showing color, it is close to ripening. For all-green varieties, just wait till fruit grows to maximum full size. You may also check if the fruit gets softer to touch, then it's ready.

Healthy Plants: Q&A from Mr Booster

What is an ideal potting mix?

Q: A few years ago, I purchased a Barbie Loquat from you, and I'm pleased to say it's been growing very well. I now have several loquat seedlings. I have read that a well-draining medium should be used, and I have found that the various formulations provided on the web for such medium seem vaguely reminiscent of the recipe provided in your transplanting instructions. Therefore, I would like to retrieve your recipe, unless you could recommend an even better one?

A: The main requirements for a good potting mix are:
- perfect drainage, allowing air circulation that is so necessary for healthy roots; oxygen circulation helps to avoid root rot
- water retention: to keep nutrients in soil
- low pH (soil acidity) which is important for most tropical plants
- adequate amount of organic matter in the mix, in combination with proper fertilizer program

In our nursery we experimented with many different potting mixes for the past couple decades. We ended up with an ultimate mix for tropical container plants that we designed ourselves. This custom mix is called -

Abundance - TopTropicals professional soilless potting mix

It meets all the requirements above which makes it a perfect mix. All our plants are happy with it. Abundance is a professional quality (nursery-grade) potting mix with great drainage characteristics, ideal for any tropical plants. It is organically derived soil-less mix, free of any additives.
Ingredients are:
- fine Canadian peat moss
- coconut coir
- perlite
- aged pine bark (soil conditioner).
See more info on soil mixes.
We have this mix available for purchase in different packaging sizes - 2, 3, and 7 gal bags.

Besides proper potting mix, all container plants require regular fertilizing. We recommend the newest, scientifically balanced fertilizers Sunshine Boosters that are natural, eco-safe, great for all edibles and organic gardening. They are safe to use with every watering, provide all necessary elements for plant daily needs, and won't burn the roots.
For your loquat tree, consider Sunshine C-Cibus, it boosts both flowering and fruit production. Loquat is Winter-Spring bloomer, hopefully you will get some crop soon!

Plant of the Month:

Fragrant Dombeya Tree

Every tropical gardener wants to have a Dombeya (a.k.a. Tropical Hydrangea) in their collection - an easy to grow, fast growing winter bloomer. These plants don't require any special care, thrive in neglect in both sun or shade, and flower profusely during Fall-Winter months - what an awesome treat! Dombeyas are also wanted for their vigorous growth habit - they can cover unwanted view in no time, fill and empty corner in your yard, create a colorful tropical display, and attract lots of butterflies and bees. They are not afraid of water logging, in fact the more you water them, the faster they grow. The large tropical leaves are beautiful - soft, fuzzy, with shallow, maple-like lobes. This plant is tolerant to both light frost and periods of drought.
Most Dombeyas grow into round, dense bushes, but this one variety of is very special. Dombeya burgessiae from South Africa actually grows into a small (10-15 ft), pretty, upright tree that is covered with beautiful blossoms during winter. The flowers are creme color with raspberry centers, attracting lots of pollinators, and what is the most special - they are sweetly fragrant! What a beauty!

Surround yourself with aromatic cloud of Dombeya winter blooms!

Musa ensete Maurelli - Red Abyssinian Banana

by Onika Amell, tropical plant expert

Q: I am looking for a colorful, tropical plant with in particular, coarser texture, to add to planting beds next to my decks and around my swimming pool. Any suggestions? I am located in St. Petersburg, FL.

A: Consider incorporating some fast growing Red Abyssinian Banana, also known as wild banana or Ethiopian banana. This is a fantastic ornamental from East Africa and an excellent choice to create a tropical feel and to add coarse-textured foliage. This plant is not a true banana and therefore does not produce any edible fruit. American gardeners were rather slow to discover this enormous perennial, but finally woke up to them over the last decade to a point where they now are considered to be one the most beautiful ornamental banana plants for the landscape and for good reason...

Cold protection of tropical container plants

Q: I am long time customer of yours, I live in San Diego California and while the summer and Fall temperatures are warm to mild, the winter temperatures dip to a point where some tropicals die off. We are experimenting with different variations of way to heat and insulate the pots we have the tropicals planted in as a way to keep them alive during the colder winter months. I was wondering if you knew of the ideal soil temperature for these tropical in order to look their best year round. All of the heaters we have installed have thermostats and temperature adjustments so we can now keep the soil anywhere between a range of between 65-75 degrees. Any advise you can provide would be greatly appreciated.

A: This is a very interesting concept you are working with. Indeed, keeping pots/roots warm, may help a lot! We've been experimenting with cold protection for a long time - for the above-ground plant parts. For sure keeping roots protected (even with a thick layer of mulch) will benefit tropical plants during winter. In case with container plants, this may help dramatically.
The guideline is, tropical plants slow down or stop their metabolism at 65F. As long as you can keep soil above that temperature - this should work great. Of course, the higher the better.
Optimum temperature for growing tropical plants in general - 70-85F. Above 90F, metabolism stops too, unless it's a heat tolerant, desert plant.

Chorisia speciosa - Exotic Pink Silk Floss Tree

by Onika Amell, tropical plant expert

When I stumbled upon my first Pink Silk Floss tree at the Naples Botanical Garden in Florida, it stopped me in my tracks. It was in full bloom and one of the most beautiful flowering trees I had ever laid my eyes upon. This tree has so much wow factor. Not only are the flowers of this native from the Amazon Rain Forest in South America spectacular, but the trunk, seeds and attractive, umbrella-like crown makes it exceptionally unique and interesting. This tree will stand out in any garden....

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!
