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

Condo Mango

Q: I was curious about indoor fruiting mango trees. I live in upstate New York and was thinking about trying to grow an indoor tree for fruit. I have a small heated greenhouse. Is there a variety that can be grown from seed that would suit my purposes and if not what is the most economical way I could obtain a cutting or small grafted plant? I keep my greenhouse around 60F in the winter and have no supplemental lighting. Are there any varieties that may work in a sunroom or other well lit indoor location?

A: There are many dwarf varieties of mango suitable for container culture. They are called "condo mangoes".
The most popular condo varieties are: Carrie, Cogshall, Cushman, Fairchild, Graham, Ice Cream, Julie , Mallika, Nam Doc Mai, Pickering. You may read more about them in our online catalog. You may also look into variety Lancetilla which is also a compact tree, and produces one of the biggest size fruit, up to 5 pounds. If you want some rare variety that hardly anyone else has - try Baptiste, an exotic Haitian dessert mango.

Your greenhouse should work for the winter time. Mango trees can take as low as mid 40s during winter and even lower as long as that cold is occasional. If you keep the temperature around 60, this should work well for over wintering. Just make sure to reduce watering to a minimum, because cool temperatures, low light and wet soil - is a bad combination for tropical plants, especially for mango trees which prefer to be kept on a dry side.

Many indoor gardeners have fruiting mango trees in their collection. However, keep in mind that the most important requirement for a mango is full sun. While you may over winter the plant for a few months in a low light conditions, in order for it to flower and produce fruit it needs lots of light. If moving the tree into full sun your yard during the summer is possible, this would be the best solution.

We always recommend SUNSHINE boosters for both over wintering tropical plants in colder climates, and for indoor gardening. SUNSHINE applications will help your tree to cope with cool temperatures and low light conditions. This will also dramatically increase flowering and fruiting performance. Another important factor for keeping your container plant healthy is quality of your potting soil. We offer a special professional mix that contains lots of good stuff: coconut fiber, peat moss, pine bark, and perlite. Fertilizing potted plants is also very important during the warm season, because this is the only way for them to get nutrients (which in the ground can be reached by spreading root system).

As far as seedlings vs. grafting - the only way to have a nicely fruiting mango tree is to plant a grafted variety. Seedlings start producing only after 8-15 years, and the quality of such fruit may be questionable. Only grafted plants can guarantee the desired taste of a variety. Besides, grafted mangoes start producing immediately - you may see fruit forming on plants as small as 3 ft, in 3 gal containers. However, during the first 1-2 years you will need to remove extra fruit and leave only 1-2 fruit so the plant doesn't get exhausted and has enough energy to establish strong root system.

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.

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.
