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.

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.

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.

Healthy Plants. Q&A from Mr Booster: How to get Ylang Ylang to flowering

Q: I am writing in reference to my Ylang ylang tree. I purchased this from top tropicals a few years ago and although the plant is doing well, I don't see any flowers yet. Can you tell me when it will flower? Do I need to do something special for it to flower?

A: Cananga odorata, Ylany Ylang tree, takes a few years until it starts flowering, hopefully it will bloom for you any time soon.
However, keep in mind that it may be a bit challenging for a potted plant. In natural conditions, this is a large tree that requires lots of room not only for the tree itself, but also for the root system. It is still possible to get Cananga odorata to bloom in container, considering the plant has all necessary nutrients for flowering. Here is the trick.

When grown in the ground, root system 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 (soluble) form, and a plant must have their constant supply for proper development.

SOLUTION:
prescribe Ylang Ylang tree the following combination of plant food:

- SUNSHINE Pikake - Fragrant Flower Booster
It will provide well-balanced amounts of high absorption Phosphorus (P) and Nitrogen (N), as well as Potassium (K) - to provide enough flowering 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 trigger flower production.

You may also consider getting dwarf varieties of Ylang Ylang that starts flowering in container right away:
Cananga fruticosa - Dwarf Ylang-Ylang Currently these high demand plants are sold out, but new plants are establishing and will be ready for sale within couple months. You may add your email to wishlist ("Notify me when available") to get notification as soon as we have it back in stock.
Ylang Ylang vines also start flowering within a year.
