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!

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.
