Healthy Plant Food: Q&A from Mr Booster

Encouraging blooms on the Hawaiian Sunset Bell Vine

Q: Please can you advise how to encourage the Stictocardia beraviensis the Hawaiian Sunset Bell vine blooms? Mine is all beautiful leaves and full sun in Miami.

A: Providing full sun, Stictocardia blooms profusely. In your area, it should be happy and thriving. However, keep in mind that these flowers can be seasonal (meaning, not ever-blooming). The good news it, Hawaiian Sunset Bell usually blooms several times a year on and off. In our garden, we have a large plant growing in the ground and covering a whole fence; we see flowers 3 times a year:
- Early Spring
- Summer (sporadically)
- Late Fall to early Winter

Make sure to provide proper fertilizer to encourage blooms. It is especially important if you grow this plant in container (where nutrients are very limited). We suggest the following fertilizer for your Stictocardia:

Tabernaemontana africana - a bush or a tree?

Q: I received a Tabernaemontana africana, but it is not the compact cultivar, from the photo, this is definitely the tree version, not the compact version?

A: The plant in your picture is Tabernaemontana africana and it is a shrub version, not a tree. The plants we have in stock are smaller size but very vigorous so they can be trained into standards.
We have this plant in our garden in the ground (3 years old) and by now it bushed out and remains under 4 ft without any pruning. Just keep in mind this plant requires regular applications of micro-elements, because the species is very susceptible to iron deficiency. The supplement we use, in case you notice any leaf yellowing, is Sunshine-Superfood.

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.

Triple Sec Mango

TopTropicals.com

By Onika Amell, tropical plant specialist

Q: I live in Mesa, Arizona. I am considering purchasing two of you Triple Sec Mango trees. Can you please give me some information on this variety and how to grow it successfully here in hot and arid Arizona, if at all?

A: Triple Sec Mango is a new name for the superior variety Seacrest. The aroma of this fruit resembles Triple Sec - an orange liqueur. It's a juicy, mid-season variety that has good disease resistance.
Mango has pretty good heat and drought tolerance. It loves sun, but there are a lot of factors to consider when growing Mango in your area.
Check your soil. Soil quality is always first and foremost: when you live in an area of Arizona with hardpan (extremely compacted desert soil) or caliche (layers of soil cemented by calcium carbonate) you will have to learn how to deal with such soil types. Amend the soil as needed.
The best time to plant is spring or fall to give your Mango a chance to get established before the really intense Summer heat starts. Alternatively, protect the tree with a shade cloth. Tender, new growth will not stand a chance unprotected, especially newly planted and/or young trees.
Mangoes are tropical and sensitive to frost and freeze damage. Young trees especially will also need winter protection when temperatures go near or below freezing. Always plant trees in a location where they will be protected from cold wind. Consider staking your newly planted Mango trees for the first year. It's never a bad idea to even stake during periods of high winds.
Make sure your planting site has very good drainage. Always use a good quality mulch around your tree as it helps to trap moisture, keeping the ground and the roots beneath it cool. Keep mulch a couple of inches from the trunk of the tree. Avoid a location that gets full day sun. Morning sun, afternoon shade is ideal. Give regular watering until the tree is established. Once established, water only when the soil feels dry.
Fertilizer with a Mango-Food. A foliar spray of micronutrient solution is always recommended during the active growing period. Use plant stimulants and microelements to improve cold hardiness and vigor.

Fruit tree size and production

TopTropicals.com

Q: I am interested in a Strawberry Tree... does this tree produce fruit while still small or do I have to wait until it is large before it produces? Should I fertilize it so it produces sooner? I ask because my garden is not large and I prefer to keep my fruit growing trees in a smaller size. Also, how big is the fruit and does it have a seed?

A: Strawberry Tree, Muntingia Calabura, is one of those fascinating fruit trees that starts flowering and fruiting in small size. We have plants growing in 1 gal containers that already have flowers. This tree is nearly year-round producer providing warm conditions. It is a fast grower, although a compact tree when mature, and can be trimmed to desirable size without affecting production.
Muntingia fruit is one of our favorites. It is super sweet and juicy, and the seeds are tiny small, not bigger than the strawberry seeds, so you don't have to spit them out. The fruit size normally about 1/2 inch, but we have a tree in our garden that produces almost cherry-size fruit! See picture above. The secret is, good watering and using fruit booster - SUNSHINE honey micro-element supplement. We also fertilize our fruit trees using Fruit Festival and Mango-Food fertilizers.
