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!

Establishing Mamey Sapote
In the photo: Mamey Sapote lre-leafing.
Q: I purchased Mamey sapote last fall and am very excited about having it in my yard. It lost leaves during the winter, but then budded and put on a lot of beautiful leaves. I was hand watering since this covid stay at home event, and thought I'd put it in a larger container, 10 gallon. About 2 months after transplant and hand watering the leaves turned yellow. I cut back on watering, allowing some dryness between. Some leaves now have fallen off, but looks like new ones forming. What have I done and most importantly now, what do I need to do so she survives? I haven't yet decided exactly where to plant her... so hoping she can stay in container for a bit longer while recovering.
A: It is possibly a combination of over-watering and seasonal
changes (re-leaf). During this time of the year, Pouteria sapote loses old
leaves and grows new ones. This plant is semi-deciduous, which means, it drops
leaves during unfavorable conditions (too dry, too wet, too cold, to hot, etc. =
any stress).
The new buds are healthy. Give it a couple of weeks. Reduce watering. Don't water again if the soil is still moist.
If planted in the ground, it will be easier to control the moisture, as long as you plant it high enough (at least 3-4" above the surrounding area, like on a little hill, for a better drainage.

Zephyranthes pulchella - sunny face of incredible Magic Lily
by Mark Hooten, the Garden Doc
...These wonderful little lilies came as a gift from a botanist studying
the native plant life of Southern Texas nearly 30 years ago. Originally
grown from seeds collected for a doctoral thesis, near the town of Refugio (along
the Southern Texas Gulf Coast, just north of Corpus Christi), this
brilliant, fetching tiny lily really deserves to be more well known. The thin,
grass-like leaves grow from small onion-like bulbs that produce an abundance of
shockingly bright cadmium-yellow flowers which greatly resemble those of certain
yellow Crocus, except on longer stems.
There is one caveat which goes along with this incredible species... it can
be wonderful, depending upon a growers situation... which is that this
species is "apomictic". This means that they produce seeds which do not require
cross pollination, and technically are clones of each mother plant!..

Establishing Cerbera Manghas
after a long shipping trip
Q: I live in Hawaii. I purchased Cerbera x manghas - Enchanted Incense. I followed the repotting instructions but it looks like dying? Is the normal for all the leaves to fall off? I only use purified water to mist and water the plant. I let it dry between watering and still it looks sad. Please help!
A: Cerbera is very sensitive to shipping stress (in particular to
darkness) and it often loses leaves in transit. Considering long trip to Hawaii, it had extra 1-2 days in transit, longer than to most of the
states.
Your plant looks very much alive, however we understand your concern about lost leaves.
You need to treat it like Plumera: keep on a dry side until it starts
sprouting new leaf growth. Once it gets re-established, you may move it out into regular irrigation or
rain.
We recommend to keep it under roof to control water input, but in very blight spot, preferably
sunny.
Make sure the soil doesn't get soggy, too much water may kill the plant especially when it is leafless and hence doesn't consume/evaporate much water.
Water only when top of the soil gets slightly dry.
Do not put into bigger container until roots start growing.
The plant should recover and start new growth under proper care. Keep us in loop how the plant is
doing!

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...

PeopleCats of TopTropicals. Cat of the Day: Story of Raja, Part 2
Everybody was touched by the tragic story of Raja - the kitten Kristi rescued from the tough street
challanges and gave her a chance for Life...
Today we continue this story. And although it is a sad one, there will be a
happy ending, and there will be always lessons we learn from the experience
of taking care of our loved once.
Raja taught us to never let our disabilities define what we can and can't
do. She taught us that every live creature deserves to know what love, a warm
home, and a family means. She taught us resilience, determination and
perseverance. Sometimes goodbye is not always an end, but a possible new beginning
with new lessons learned...

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.

Healthy Plants: Q&A from Mr Booster
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.
