Healthy Plants: Q&A from Mr Booster

How to fertilize Caladiums and other Aroids

By Ed Jones, the Booster Guy

Q: I have a large collection of Aroid plants, different Monsteras, Philodendrons, and several unique varieties of Caladiums. I've been always told that Caladiums should not be fertilized, they don't like it. Is it so?

A: Caladium farmers often say that these plants don't need any additional fertilizer and that they really don't like it... The thing is, caladiums do not like DRY fertilizers, and this is why. Most Aroid plants do not like being watered too often, so dry fertilizers in combination with infrequent watering create excessive salinity for the root system. We have run some tests on the proper fertilizers for caladiums and the best results were performed after using SUNSHINE Robusta. It is amino acid based, so the delicate, large-leaved Aroid plants will not have to work quite so hard to take up the nutrients, and there will be no nutrient lock up in soil. The nutrients are readily available to these plants.
In this article, you will see some test results of caladiums fertilized with SUNSHINE Robusta vs. other brands of fertilizer, with more vigorous growth and larger leaf size occurring after use of Sunshine Robusta...

Caladiums do not have to be just an accent plant. They can also be the focus point of a garden area. It is said that as many as 98% of the world's caladium tubers come from right here in Highlands County, Florida, also home to the Sunshine Boosters manufacturing facility. It is such a big deal that they have a Caladium Festival here each summer. The fields are absolutely stunning in all of their colors. This year the festival runs this weekend, July 23 - July 25.

Fast-fruiting trees?

Q: More of a question than a review, but a review regarding your catalog, it would be easier for us buyers, if we could search for plants that produce fruit in 2 years or less, I don't have the patience to wait longer than that for fruit. I'm trying to buy for a fairly good sized garden but want some fast growers and fruit produced in 2 yrs. Can you help me out?

A: Fruiting time depends on many factors (established size, growing conditions, fertilizing, and even specific variety), this is why we can not just put a simple icon "will fruit within 2 years".
However, most grafted and air-layered fruit trees, including all Mango, Avocado, Loquat, Sapote, Sapodilla, Lychee/Longan, Peaches and Nectarines - will fruit right away. If you see in our store "grafted" or "air-layered" in plant description - these trees will fruit soon. Some of them already flowering and fruiting.
Some non-grafted trees or seedlings like Annona, Artocarpus (Jackfruit), Eugenia, Guava, Banana, Dragon fruit, Mulberry, Blackberry/Raspberry - will fruit within 3-4 years from seed or even sooner (Banana, Mulberry, Dragon fruit, Blackberry-Raspberry - within a year). Usually it says in description that this plant can produce fruit soon.
Bigger size plants are more established and have more energy to produce, so try to get larger size plants if your budget permits, and especially if you can pick up bigger plants rather than shipping them - obviously, shipping has size limitations.
In addition, all spice trees like Bay Leaf, Bay Rum, Allspice and many more - they will produce spice for you right away, so you don't need to wait at all!
If you have questions about fruiting time on any specific plant you put your eye on, don't hesitate to ask!

URBAN TROPICAL GARDENING:
10 secrets of successful Container Mango growing on a balcony.

Q: I live in Miami in apartment on a second floor, and I have a balcony with SE exposure. I wonder if I can grow a mango tree in a pot? Will it fruit for me? I recently moved to South Florida and I don't know much about tropical plants; but I tasted real fiberless mangos from someone's garden - it was so delicious and different from those in the grocery store. I wonder if I can have a fruiting tree on my balcony? And if yes, how do I plant and take care of it?

A: Yes, you can! Here is what you need to do:
1) Temperature. You are lucky to live in Tropics, keep it on a balcony year round.
2) Light. Position the pot in a spot with the most sun exposure. Mango trees can take filtered light too, but the less sun, the less fruit you will get.
3) Soil and Container. Use only well drained potting mix. Step up the purchased plant into next size container (3 gal into 7 gal, 7 gal into 15 gal). When transplanting, make sure to keep growth point (where roots meet the trunk) just at the top of the soil. Covering base of the trunk with soil may kill the plant.
4) Water. Water daily during hot season, but only if top of soil gets dry. If it still moist, skip that day. Mangoes (unlike Avocados!) prefer to stay on a dry side.
5) Fertilizer. Use balanced fertilizer once a month, 1 tsp per 1 gal of soil. Do not fertilize during fruiting - this may cause fruit cracks.
6) Microelements. Apply SUNSHINE-Superfood once a month. This will help your mango healthy, vigorous, and resistant to diseases. Use SUNSHINE-Honey to make your fruit sweeter.
7) Insect control. Watch for scales and mealybugs, clean with solution of soapy water + vegetable oil (may need to repeat 2-3 times with 10 days interval), or with systemic insecticide like imidacloprid only as needed (if non-harsh treatment didn't help). Most Flea shampoo for dogs contain that chemical, you may try that shampoo solution.
8) Trimming. Once potted, do not remove leaves that are discolored or have spots until new growth appears. Dark dots on mango leaves, especially in humid climate like Florida, may be signs of fungus. Treat with fungicide according to label, and remove only badly damaged leaves. Trim crown as needed after flowering and fruiting (by Fall). Train into a small tree, and you may remove some lower branches eventually.
9) Flower and fruit. Mangoes are winter bloomers with bunches of tiny flowers coming in thousands. Many of them set fruit (if pollinating insects present). Keep in mind that young trees can only bare a few fruit. Normally a tree will drop excessive fruit and keep only a few that it can manage. To save the young tree some energy, remove fruit if too many and leave only 2-3 for the first year. It will pay you next year with more abundant crop.
10) Variety. Last but not least: Choose the right variety for container culture! Pick from "condo" dwarf varieties such as Icecream, Nam Doc Mai, Carrie, Cogshall, Julie, Fairchild, Pickering, Graham, Mallika, and a few others - check out Mango Chart pdf and full list of our Mango varieties.

Plants for South Texas and other hot states

Q: Pretty much adore last newsletter. Haven't been buying because our weather here in deep south Texas is so bad it is stunting and killing even the Tamaulipan Scrub! Do you have a cure for that? :) I have every expectation the new grafted Plumeria I purchased from you last year will bloom soon. One of my favorite plants. Thanks again and keep up the good works.

A: Yes, there is a "cure" - using biostimulants that improve drought- and heat- resistance (SUNSHINE boosters), plus the right plant selection. In fact, there is a large number of tropical rare plants that can be successfully grown in hot climates like yours. One of our partners lives in hot and dry Arizona area and has an amazing tropical garden that includes many fruit trees (Mango, Persimmons, Pomegranates, Loquats, etc). Here you can see a few pics from his garden.
Your choice is absolutely right about plumerias. Other easy plants would be Desert roses - Adeniums, and Fancy Euphorbia millii - all these come in so many varieties of colors and bloom throughout most of the year. Our special recommendations for you would be also:

Bougainvillea Dwarf Pixie
Jasmine sambac
Calliandra selloi Pink Lilian
Dracaena marginata Tricolor - Colorama, Money Tree
Hamelia patens Lime Sizzler - Variegated Fire Bush
Jatropha berlandieri - Buddah Belly
Pedilanthus tithymaloides - Devils Backbone
Trachelospermum asiaticum Mandaianum - Dwarf Confederate Jasmine

See full list of more plants that are suitable for hot and dry landscapes.

Apply fertilizers, miscroelements, and plant stimulants for improving heat tolerance

Growing by the sea

Q: Please recommend me some interesting plants that can grow on my waterfront property and can withstand some salt wind. All my neighbors have Sea Grape trees and bougainvilleas, and I want something different and special. I would love to have some colorful or fragrant flowers, or fruit around my paradise home.

Q: Considering your neighbors successfully grow Sea Grape (Coccoloba), and Bougainvilleas, you have a mild, frost free climate. There is a number of spectacular and useful tropical plants that are salt tolerant. Orchid Trees - Bauhinias, Poincettia - Delonix, and Geiger trees - Cordias, are very showy flowering trees. For large size bushes, try Dwarf Poincianas - Caesalpinias, and Scarlet-Coral Erythrinas. Frangipani - Plumeria, come in different colors and bring you perfume fragrance from Hawaii. And of course, Desert Roses - Adeniums, can be grown and showy specimens anywhere in your yard, both in the ground or as potted bonsai.

Most palms, especially popular Coconut Palm, source of tasty fruit and drink, are highly tolerant to salt breeze. If you are looking for something that nobody has, Lipstick palm, or Sealing wax palm - Cyrtostachys lakka, is definitely the most spectacular palm you can find. It is a stunning feather palm that develops a brilliantly red trunk. Palm is originally from Malaysia, but has been introduced to Costa Rica and other tropical areas of the world. Sealing Wax Palm seeds are very slow to germinate, up to a year, and large specimens are very rare and hard to find even in rare tropical plant nurseries. This palm will require a good overhead light, and constant warmth (above temperature 55F). It is definitely worth an effort to grow this beauty.

You may add more tropical accents to your landscape by the sea with many varieties of showy heliconias.
