How to grow Cerbera and make it flower
Q: I purchased Cerbera manghas - Enchanted Incense a year ago. As you see from the photo, it's doing great however, no blooms. I fertilize properly and very often and use worm castings for micronutrients. Yes it's not "your" fertilizer, but my plumerias, that are also in pots they are over 5 feet tall and blooming like crazy. I don't see any inflows coming on the Cerbera at all and it is hot and humid here in North Carolina, so it's happy but no sign of blooming. What is your advice?
A: Top Tropicals first brought Cerbera manghas into the US plant market a few years ago, it was recommended to us by our friend, plant taxonomist John Mood who visited Thailand, and among other exotic plants noted this fragrant beauty. Since then we've been successfully growing this plant, it has become one of everybody's favorites.
Generally speaking, Cerbera culture is very similar to Plumerias. These plants are closely related. So if you know how to grow Plumeria, you sure will succeed with Cerbera. Hot and sunny location, well-drained mix, moderate water and bloom boom fertilizer will do the trick. However, we have noticed a few distinctive features that make this plant somewhat challenging at times.
1) Flowers
For past years, we've been studying what triggers its flowering.
Sometimes these plants start flowering in 1 gal pot, 1 ft tall. Other times a large
developed tree 5-6 ft tall, in 5-7 gal pot, grows beautiful foliage with no
signs of flowers. Eventually all of them bloom, no matter how stubborn they
are, it's just some individual plants start flowering sooner than others, all
grown in the same conditions.
One of our plants in the ground, a well-branched tree, was covered with
flowers for a few months, but only on the 3d year after planting. Before that,
it only produced a few random blooms. Others bloomed in pots at very young
age.
The following factors benefit to Cerbera flowering:
- full sun at least 10 hours a day
- hot temperatures above 85F
- regular water but not heavy rains
- regular fertilizer - Bloom Booster type
- very good drainage and drying out before waterings. If root ball stays
moist, the plant may look healthy but won't set flower buds. Keeping on a dry
side will encourage flowering. Very similar to Jasmines: they bloom like crazy
in April while it's hot and dry in Florida, but once our summer rainy season
starts, they reduce blooming.
We highly recommend using Sunshine Megaflor bloom booster or SUNSHINE Pikake in combination with micro-element supplements Sunshine Honey (B-Mo) and Sunshine Superfood (complex micro) that induce flowering. Dry and granulated fertilizers may not supply exactly what a plant needs: certain elements that trigger flowering may be missing. Sunshine Boosters formulas are scientifically balanced, they contain precise amounts of nutrients needed for setting flowers. Besides, excessive salts from regular dry fertilizers create nutrient lock up that may retard plant metabolism; with liquid amino-acid based Sunshine boosters, plants consume the whole menu of elements without building them up in the soil.
2) Fruit
Fruit of Cerbera are very pretty and cover the tree after profuse flowering. To inexperienced eye they may look very much like small mango or avocado fruit - so make sure kids or visitors don't try to eat them! Cerbera seeds are extremely poisonous.
3) Leaves
If you ever grew Passiflora or Milkweed, you know how leaves can be
eaten by caterpillars overnight. This may happen to Cerbera too, as we
discovered. In Florida environment this exotic plant doesn't have natural predators for
protection from certain insect species that may feed on it. So watch out and
if noticed first signs of leaves damage - its time for insect control.
Other than that, Cerbera foliage is usually beautiful and colorful, here in
Florida it looks much healthier than that of Plumerias often affected with
rusty residue during high humidity months.
Hope this helps. The Cerbera fragrance is enchanting, it is worth the efforts and waiting!

Healthy Plants: Q&A from Mr Booster
Why my Avocado is not flowering?
Q: I have 5 avocados. Three of your cold hardy varieties and two others that have all flowered and set fruit in the past. The last two years including this year, not a single one of them has put out any flowers. I am getting lots of new growth like one would expect on a tree too young to flower. The last two years have been very mild with out any damaging frost where in previous years they lost all their leaves due to frost yet started putting out flowers once winter was over. I am confused because they have all flowered and set fruit previous years. Any ideas would be appreciated.
A: From information you provided, and considering the trees get
lots of full sun and cold was not an issue, the only explanation is - lack of
nutrients. Here is an example.
Very common situation: you get a small 2-3 ft Avocado or Mango tree in 3
gal pot (or even smaller) from a nursery, full of flowers, and sometimes even a
small fruit. You bring it home, plant it in the ground or a bigger pot, it
looks happy and grows like crazy. Then next year - oops, no fruit, sometimes
not even flowers. What happened?
When the tree lived in a nursery, it was provided with all necessary
nutrients through the injector systems (continuous feed); or some nurseries may use
top dress smart release on regular schedule. Regardless of fertilizer type,
professional grower's set up delivers plant food non-stop, on regular basis, with balanced formulas. Plants are not only growing fast but also ready to produce, since nutrients are always available for a full growth cycle.
When you plant a tree in the ground (or larger pot), conditions change.
They may be beneficial for the plant: lots of room for roots to establish, hence
lots of vegetative growth. Even if you planted it using good quality fertile
soil, this soil may contain mostly nutrients responsible for vegetative
growth (branches and leaves). Chances are, your soil may be rich in Nitrogen
(good for green growth), but poor in other elements responsible for flowering and
fruiting (Phosphorous, Potassium, and many important micro-elements such as
Molybdenum, Boron, Iron, etc.). Besides, existing soil gets exhausted
quickly, and within a year a two, if you don't add fertilizer, flowering and fruiting may be reduced or even stopped.
This is why fertilizing program is very important for fruit trees that are expected to bring a crop soon.
We recommend:
- SUNSHINE C-Cibus - Crop Nutrition Booster - balanced food for fruit
trees
- SUNSHINE-Honey - sugar booster - promotes more efficient blossoming and
pollination, makes flowers bigger and reduces bud drop
- SUNSHINE SuperFood - for improving fruit trees production
Also keep in mind that some fruit trees have a habit of "skipping" a year and may either produce less or not produce at all every other year. In any case, balanced nutrition program can help to fix this "bad habit".

How to grow Soursop in a pot
Q: Is it possible to grow soursop in a large pot for life?
A: Soursop, or Guanabana - Annona muricata - is actually one of those tropicals fruit trees that
can be easily cultivated in a container. Most plants of genus Annona have compact nature, and these fruit trees usually start
production at a young age, as early as 3 years from seed. Annona muricata
seedlings take a little longer to fruit, this is why we offer grafted trees, which can start producing right away.
We have a very interesting article about growing Soursop in an
apartment. The article was written by an indoor gardener who lives in a very small
apartment in Moscow, Russia. He grew this tree from seed and after years of
cultivation fun, he finally got several large delicious fruit! It is an amazing
story. We have it published in our Tropical Treasures magazine, download the whole issue #7, get a hard copy, or you may download PDF file of the single article.

How soon will Guava tree fruit?
Q: Can you tell me how your Guava trees are propagated? Grown from seed vs. air grafted, etc.? I'm interested especially in the Barbie variety. In particular, I'd like to know how long it takes them to bear fruit - I live in Southern California zone 10b, with good sunlight.
A: Guavas can be propagated by seed, air layers, or grafting.
Propagation method depends on the species.
Cattley guavas - Psidium littorale - are usually grown from seeds and start flowering
and producing as early as in 2-3 years from seed. Tropical guavas, Psidium guajava - especially named varieties, are propagated usually by
air layers, and the rarest varieties like Variegated Honey Moon are often grafted, although they will come true
from seed (it's just takes them longer to fruit). Both air-layered and grafted
plants start producing right away, usually on the same year of planting or
next year, depending on growing conditions.
Barbie Pink is a superior variety, very popular among fruit lovers. It
produces large aromatic fruit with a bright pink pulp and very few seeds. This
variety is air-layered; in our nursery, these plants start flowering and
setting fruit in 3 gal containers.
Plant this tree in full sun and provide regular watering, guavas don't
like to dry out. Use fertile soil, with at least 50% of compost, and add some
soil conditioning components for better drainage: bark, sand, perlite, etc.
Mulch well, just make sure to keep mulch 2-3"away from the trunk. Follow our
detailed planting instructions that come with every plant, and you are good
to go!

Spring is coming, plants need food! Time to fertilize...
Last winter was long and snowy in the most part of our
country. Hold on fellow gardeners up North, it is almost
over!
Here in Florida we have been blessed again with a mild
winter without serious cold snaps. Early Spring that is
already in the air. Look at this picture of flowers in our
front yard now.
If the weather is already warm in your area (low
temperatures above 55), it is time to start fertilizing.
We are sending our love and support to tropical Puerto
Rico suffered from hurricane last year, and will be happy
to help you guys to restore your lost gardens!
CHECK LIST
what
to do to give your garden a good kick start:
1. Slow release granulated food. Apply Slow Release Fertilizer and
continue once a month. 1 tsp per gallon of pot, or a
handful for in-ground plants. This will provide essential
macro elements (NPK) required for a plant growth.
2. Water soluble micro-elements. Besides
macro-elements, plants need many other elements that most
of the time missing in soil. A lack of micro-elements
causes different deficiencies, resulting in weak root
systems, slow growth, deformed leaves, leaves yellowing,
lack or no flowers/fruit. Apply these supplements as a
foliar spray once a month to induce healthy growth and
flower/fruit development. We recommend the following
micro-element products to keep your plants healthy and
vigorous year round:
a) SUNSHINE SuperFood - plant
health booster. This revolutionary new liquid complex
contains ALL microelements needed and can fix all possible
problems occuring to your tropical plants - from roots to
flowers and fruit. We have convenient dropper bottles of 5 ml for small plant
collections, 50 ml for larger gardens, and
100 ml for professional
landscape applications.
b) SUNSHINE-Micro - Microelement
booster - for common iron deficiency (pale leaves)
c) SUNSHINE-Super-Iron -
Microelement booster - for severe iron deficiency
(severe yellowing leaves)
3. SUNSHINE plant boosters -
SUNSHINE-E, -BC (caudex plants and bonsai), -H (house
plants). Apply these natural plant stimulants to
help plants recover from cold, dormancy, increase plant's
metabolism and make a plant more readily absorb both
Macro- and Micro-elements. SUNSHINE boosters also will
help plants grow vigorously, withstand Summer heat and
drought, and produce bigger and better flowers and fruit.
4. Kickstart a sweeter fruit. To get a better and
sweeter crop in Summer and Fall, you need to start first
application now. SUNSHINE Honey - is natural,
Amber-colored, honey-like liquid microelement product for
fruiting and edible plants that will make them sweeter,
tastier and more flavorful! Very effective for tropical
fruits, tubers, vegetables. Great for tropical fruit
trees: Mango, June Plum, Annonas, Tropical Cherries,
Carambola, Citrus; subtropical fruit trees: Peaches,
Apricots, Loquat and berry plants (blackberry, mulberry,
etc.)
5. SUNSHINE-S. Don't
forget to plant seeds! It's a perfect timing
now to start your tropical garden indoors even if it is
still cold outside. Soak them in SUNSHINE-S solution to
increase germination rate.
