Spanish Lime Tree

Q: Do I need two plants of the Spanish lime to have fruits? Do you have a grafted tree that I would only need one plant?

A: From our experience with Spanish Lime trees - Melicoccus bijugatus, fruiting habit really depends on variety. There are self-pollinating varieties that only require one tree. Seedling usually require cross-pollination between two trees for better production. It doesn't mean that one tree won't bloom or fruit - it will, but production may be lower than if they were cross-pollinated.
The Spanish Lime trees we currently have in stock are seedlings from a good, self-pollinating variety Key West, however, only grafted trees are precisely true to variety since they are technically clones. Seedlings normally take a few years (3-4) until they start fruiting. Spanish Limes don't have to be grafted to produce quality fruit, however, grafted trees may take less time till they fruit.
This species is really hard to obtain and we do not have any grafted trees now, and probably not for another year. So if you really want this fruit tree, you may want to try at least with a seedling. We only have a few left in stock and many people want them. Otherwise, you may sign up for the wish list and wait until we (hopefully) have grafted specimens (enter Melicoccus bijugatus in wish list).

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!

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...

How not to kill gardenias?

Q: I have tried to grow gardenia in pots for years and never keep them alive. When i look on camellia websites they say fertilize potted plants twice a year. I'm confused as I tend to kill them with kindness haha. Also, if our tap water has high cal/mag and that stops the gardenia getting other nutrients why would I make up the feed with tap water? So confusing and online is mixed messages...

A: Gardenias are not the easiest plants to grow, however, they are easier in pots than in the ground: they prefer acidic soils, and in many areas soils are alkaline. The most important factor is balanced and sufficient nutrients. In the ground, plants have no limits to reach out to different elements by spreading their root system. In a pot, once all the good stuff is consumed, plants start suffering nutrient deficiency. This is why a balanced feeding program is important.

Generally speaking, Cal/Mag in tap water cannot be bad, because they are essential elements, good for plants (in proper amounts). However, just Cal/Mag is not enough. This is why you need a balanced liquid fertilizer for plants that prefer acidic soil. Excessive Cal/Mag alone can create nutrient lock up, especially if they are chelated with EDTA like in dry fertilizers, which are not fully accessible for plants.
We recommend natural, Amino-Acid based fertilizers that are completely consumed by a plant and are safe to use with EVERY watering, even in Winter. They are scientifically formulated and cover all plant needs. For your gardenias, you should use SUNSHINE Pikake - Fragrant Flower Booster.
Another important factor is proper watering. Gardenias like regular water but don't like wet feet = well drained potting mix is a must, similar to Abundance professional growing mix.

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!

How to keep bugs away naturally?

Q: I started moving my tropical plant collection indoors as it's getting colder... And all of a sudden, I noticed bugs on leaves! I know for sure all my plants were bug-free when I kept the pots outside in my lanai. What happened? And how can I keep them clean and healthy without using any harsh chemicals? I have many edibles and herbs that I use in my cooking and prefer to stay away from insecticides. Any suggestions?

A: It is very common when healthy looking plants, once moved indoors for the winter, get insect infestations. The main reason is change of environment that puts a plant into stress and makes it susceptible to parasites and diseases. Just think about what a plant is missing, a whole combination of necessary conditions that provided a good life:
- Bring light -> light level reduced, so beneficial UV spectrum is gone
- Air circulation -> less wind = more bugs thriving
- Warm temperature -> from upper 80's in summer to 70's in your AC room
- Air humidity -> although humid air is believed to be causing some issues (for example fungus), however, reducing humidity overall puts a plant into stress and makes it more vulnerable.

What fig trees are good for Florida?

Q: My baby fig tree was sprayed by the lawn people with weed killer :( Any ideas? Also what figs do you have available to grow here in Florida?

A: Unfortunately once a plant is affected by a herbicide, there is not much you can do about it. If you don't rinse the chemical within a few seconds, it gets into the plant internal system and nothing can be done to save the plant. The tree may remain green for a few days up to a week, but then gradually dies back. If your fig tree wasn't rinsed immediately after herbicide spray, it is probably too late.
If you want to replace it with a new one, here is a few suggestions of our favorite fig varieties which are great producers and grow well in Florida heat:

Brown Turkey Fig - our favorite!
Black Mission Fig
Beers Black Fig
Texas Everbearing Fig
Magnolia Fig
LSU Purple Fig
Olympian Fig
Texas Blue Giant Fig
See full list of Fig Trees.

Make sure to get appropriate plant food for your fig tree so it develops faster for you and gets well-established before winter: 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.

Healthy Plant Food: Q&A from Mr Booster

Why my Sapodilla is not fruiting?

Q: I bought a Sapodilla tree from you several years ago, Silas Woods. I live in Houston area. The tree grows and produces blossoms for fruits, but then they just dry up and fall off. To-date, I have not gotten any fruits off the tree. Is there a reason for this? I really want a fruiting tree because Sapodilla is one of my favorite fruits. I have attached pictures of the tree. Please help.

A: Silas Woods is a free-flowering variety and in favorable conditions it should produce fruit almost year round, considering warm temperatures. The fact that the tree is producing flowers indicates that it is strong, overall healthy and ready for production, but for some reason these flowers don't set fruit. There may be several reasons for such behavior.

1) Too high temperature and too low humidity
In Houston area, humidity should be good in summer. However, if temperatures stay above 90F for a long time, this may cause flower dry-n-drop.
Solution: try to move the potted tree into filtered light, or in a spot where it does not get direct burning sun during the hottest hours of the day (morning sun is the best)

2) Root bound.
Solution: check if the tree needs stepping up into a larger container.

3) Lack of certain nutrients that are responsible for proper fruit formation.
In particular, elements B (Boron), Mo (Molybdenum), and a few other micro-elements (Fe - iron, Cu - Copper, etc.). This is most likely the cause of a flower drop. This is very common reason for undeveloped fruit or lack of fruit in container-grown fruit trees. When grown in the ground, plants can reach out to all necessary elements in surrounding soil (considering soils are not too poor on necessary elements). In a pot, a supply of nutrients can be exhausted very quickly, so a quality fertilizer program is very important. Fertilizer must include all necessary nutrients in easy accessible form, and a plant must have their constant supply for proper development.
Solution: prescribe to your Sapodilla tree the following combination of plant food:
- SUNSHINE C-Cibus - Crop Nutrition Booster. It will provide well-balanced amounts of high absorption Nitrogen, as well as other macro-elements - to provide enough energy to the tree, plus a combination of all necessary micro-elements. It is safe to apply this fertilizer as frequent as with every watering, including winter time.
- SUNSHINE-Honey - sugar booster. This supplement has a high content of elements Mo and B - once the tree starts getting them on regular basis (a few times a year, according to the label), it will change its habit dropping flowers and/or premature fruit drop. As extra bonus, Sunshine Honey makes fruit sweeter by bringing sugars from all over the plant and concentrating them into fruit.

4) Lack of pollinating insects.
Solution: For most effective pollination, we always recommend to put some pieces of fruit under the tree, apple peels, or even banana peel. Those attract tiny beetles that are responsible for small flower pollination.

With winter time approaching, fruiting season is about to end, however, do not get discouraged and start the fertilizing program right away: this will bring up the plant into a healthy stage within a few months, and by next season it should be covered with fruit you like so much! Remember, Sunshine liquid fertilizers can be used year round, including winter, without a risk to burn roots or overdose, as long as you follow label instructions.

Fast-fruiting trees?

Photo above: Annona reticulata - Red Custard Apple

Q: More of a question than a review, but a review regarding your catalog, it would be easier for us buyers, if we could search for plants that produce fruit in 2 years or less, I don't have the patience to wait longer than that for fruit. I'm trying to buy for a fairly good sized garden but want some fast growers and fruit produced in 2 yrs. Can you help me out?

A: Fruiting time depends on many factors (established size, growing conditions, fertilizing, and even specific variety), this is why we can not just put a simple icon "will fruit within 2 years".
However, most grafted and air-layered fruit trees, including all Mango, Avocado, Loquat, Sapote, Sapodilla, Lychee/Longan, Peaches and Nectarines - will fruit right away. If you see in our store "grafted" or "air-layered" in plant description - these trees will fruit soon. Some of them already flowering and fruiting.
Some non-grafted trees or seedlings like Annona, Artocarpus (Jackfruit), Eugenia, Guava, Banana, Dragon fruit, Mulberry, Blackberry/Raspberry - will fruit within 3-4 years from seed or even sooner (Banana, Mulberry, Dragon fruit, Blackberry-Raspberry - within a year). Usually it says in description that this plant can produce fruit soon.
Bigger size plants are more established and have more energy to produce, so try to get larger size plants if your budget permits, and especially if you can pick up bigger plants rather than shipping them - obviously, shipping has size limitations.
In addition, all spice trees like Bay Leaf, Bay Rum, Allspice and many more - they will produce spice for you right away, so you don't need to wait at all!
If you have questions about fruiting time on any specific plant you put your eye on, don't hesitate to ask!
