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".

Ylang Ylang leaves after winter
Q: Hi, I purchased ylang ylang tree a couple of years ago. It's grown quite well in my Greenhouse but I'm having some trouble figuring out if I'm watering it too much not enough or if it has an insect. Can you please take a look at my photos and maybe give me a suggestion of what my problem might be?
A: It is normal for Ylang Ylang tree to get dark spots during
winter time. Sometimes Cananga gets whole branches darkened (especially dwarf variety fruiticosa), some may even fall off. But they will be replaced
with new growth in Spring-Summer. There is nothing wrong with your plant, it is
just a reaction to cold and short day light when you keep this plant indoors. These leaves eventually will fall
off as the weather warms up, and will be replaced with a new fresh green growth.
Luckily, Cananga is not susceptible to insects and diseases, but its leaves
can look unattractive in winter.
Make sure to keep watering at minimum until temperatures raise to 80's.
Start fertilizing as soon as new growth appears. We recommend SUNSHINE Pikake
- Fragrant Flower Booster, an ultimate fertilizer for fragrant plants.

Dragon Fruit Magic Tricks
Q: I purchased two sweet red pitayas, that arrived and were planted on May 28, 2020, they were damaged but not serious. my question is this one pitaya is a beautiful green, and has grown 6or 8 "already, the other is bigger and is a grayish green and has not shown any sign of growth at all in six weeks, how long do I wait before I throw it out and buy another?
A: Being a cactus, sometimes Pitaya slows down its growth waiting
for more favorable conditions. If one of your plants doesn't show any new
growth, just give a it some more time and make sure the plant stays happy. To
make pitaya happy, provide the following:
- Water. Unlike most cacti, Pitaya prefers regular watering (but not
a wet soil). Make sure it is planted in well-drained media. Do not water
again if soil remains moist, wait until it dries out on the surface. During hot
weather, Pitaya enjoys light daily watering.
- Light. Unlike most cacti, Pitaya benefits from a filtered light
especially while establishing. Try to create a temporary shade over the plant
until it starts active growth (if grown in the ground), or move the pot in
filtered light. Dull color or dry spots are signs of sun burn. Once the plant
shows new growth, you may remove sun protection, or move the pot gradually into
the full sun.
- Food. Pitayas are heavy feeders. Use the following fertilizer:
SUNSHINE C-Cibus - Crop Nutrition Booster
Q: I've been growing dragon fruit cuttings from Okinawa, Thailand and Vietnam for several years in pots and cannot get them to fruit. Any fertilizer suggestions? I live in Northern Virginia so I bring the massive pots in the garage under lights and a heater for the winter but back outside once the temperature warms up.
A: There is a little trick to get Dragon fruit to flowering and
fruiting. This plant likes flowering when it is attached to a strong support.
In commercial plantations, they use special trellises/frames made out of
logs, but you can make one yourself using simple materials.
See article: Do-It-Yourself Support Structure for Dragon Fruit.
And of course, don't forget a special plant food for tropical fruit - Sunshine C-Cibus.
You can successfully get your Dragon fruits to fruit in pots, providing
bright light in Summer. In Winter, keep the plants on a dry side to give them
some rest and a chance to hibernate before the next fruiting season.

How to get Canistel tree to produce
without dropping flowers and fruit
Q: My Canistel tree is 3 1/2 years old and is growing very well, see the picture below. It gets hundreds of pea sized "berries" but then they fall off. No canistel fruit. What's wrong?
A: You have such a nice looking tree, it is a shame you can't get
any fruit to ripen.
In our experience, Pouteria trees dropping fruit prematurely is a very common problem.
There may be one of the following reasons, or a combination of them:
- Cold winters may affect production, and while Canistel is generally
pretty hardy tropical plant that can easily withstand short periods of chill, the
fruit may never form properly if it had a cold winter.
- Lack of water. Canistel tree is pretty drought tolerant, but for the
proper production cycle it needs regular irrigation. Especially during hot
summer.
- The tree may be not strong enough; young trees drop fruit very often when
they don't have enough "fruiting energy" built up in their system.
Your tree looks well established and vigorous, however, flower/fruit drop
is often a sign of insufficient nutrients of particular kind, usually Boron
(B) and/or Molybdenum (Mo): either when a tree is too young and not strong
enough, or because of poor soils and lack of necessary elements.
Here is what can be done, considering you live in a warm, frost-free climate.
1. Provide regular fertilizing program. We recommend liquid
fertilizers Sunshine Boosters that are safe to use with every watering and year
around. It is beneficial to switch plants from traditional "slow-release"
fertilizer to the liquid one because it makes a huge difference in plant growth
and flower/fruit quality and quantity. See also:
- Why liquid fertilizers are better than dry
- Article about benefits of liquid fertilizers.
Use this plant food for your Canistel tree:
SUNSHINE C-Cibus - Crop Nutrition Booster
2. Apply micro-element remedies that are very effective for improving fruit production, especially when flower or fruit drop occurs:
SUNSHINE Honey - promotes more efficient blossoming and pollination, makes
flowers bigger and reduces bud drop.
SUNSHINE SuperFood - improves plant vigor and quality and size of
flowers
These are all natural, eco-friendly supplements that work great for fruit
trees and other edibles.

Fertilizing in Winter
Q: I have many tropical plants in my garden, both in the ground and in pots. I realize it is wintertime and some of them, the Hydrangea, Hibiscuses, and roses are in bloom but the rest of them seem wilty and droopy. Is it alright to fertilize them now, or should I wait for a few days? I have an all purpose tropical fertilizer and a 20-20-20 also. Please advise what to do.
A: During wintertime, tropicals may suffer from low temperatures
and lack of sunshine which causes droopy leaves, and leaf loss.
Regardless of the cause and plant condition, you should NEVER apply
traditional dry fertilizers during cool months. When cold, dry fertilizers
(EDTA-chelated) may create nutrient lock up in soil and damage the roots. Dry
fertilizers (both granulated and water-soluble) can be used only during hot season -
when min temperatures stay above 65F for at least a week in a row, and
daytime temperatures are over 75-80F. During hot, active growth season plant
metabolism increases. This provides less chance for a chemical root burn, as the
nutrients are used up quickly.
However, liquid fertilizers, as long as they are amino-acid based, can
be used year round. From our own experience last winter, we discovered that
fertilizing sickly looking plants (with signs of cold damage and root issues)
with Sunshine Boosters actually revived those plants. Sunshine Boosters even
brought back to life some hopeless specimens. Take a look at this gardenia
that grows in our garden (picture above). See full article.
In your case, it would be beneficial to use a mild formula of liquid
boosters in combination with Sunshine Epi -a natural plant hormone that boost their growth and helps
to cope with cold-, temperature- and low-light-related stress.
These are the products we recommend:
- Sunshine Bombino - add to every watering
- Sunshine Epi - twice a month as foliage spray
Since you grow plants in pots, feeding program is especially essential,
because plants are limited with a container size where roots can't reach out to more food in the outer soil.
In professional nursery set up with injector irrigation systems, container plants are fed daily (depending on season, more than once a day) with every watering. This is why greenhouse plants are so healthy looking.
So feel free to give your plants Sunshine boosters with every watering,
dozing according to the label. During cold period, plants need less frequent
watering, so fertilizer input will be balanced accordingly, it will depend on
temperature and plant metabolism.
Sunshine Bombino - mild, "pampering" formula for young and tender plants, as well as plants recovering from stress and/or winter damage.
