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.

Jungle on Windowsill 101

Q: I got a Jasmine Sambac and a Tahitian gardenia as presents, they are very cute plants with flowers and flower buds. I would like to be able to keep them alive and hopefully happy for a long time, but I don't know much about growing tropical plants, and I am not sure if my thumb is green enough to make everything right. What do they need? How much sun? How much water? What kind of soil? Sorry for all these (maybe silly) questions, but I want to keep them alive, please help! I live in Wisconsin and we had some snow again last week.

A: Growing tropicals is not a hard work, it is a lot of fun! These plants are actually a good starters for a beginner who wants to try growing tropical plants, no matter if you live in a mild frost-free climate, or up North where you can have these beauties as houseplants. Below are a few simple steps for you:

1. Read. Follow planting instructions included with your plants. Check plant names on the tags and learn more about them from our online catalog.

2. Soil. Plant in quality potting mix - it must be porous and well-drained, never use heavy soils (top soil or garden soil are no-no), in a pot exactly the size of the root system. You can step up your plants in the next size container once you notice vigorous new growth. Next size means: 4" pot can go into 6" pot, 6" pot into 10" pot, etc. Too big of a pot may create rotting environment, root system must fill the entire container to use all the moisture from the soil. Container must have good hole(s) for excess water to drain through. Put the pot in a saucer and get rid of excess water every time after watering.

3. Light. Most tropical plants require lots of light in order to produce flowers. If you ever visited Florida, remember the bright sun? - these are ideal light conditions for tropicals. Up North, provide as much light as possible: a bright spot on a windowsill of Southern or Western exposure would work the best. If the sun gets too hot in summer afternoon, you may shade the window a little bit with a sheet of white paper to avoid leaf burn.

4. Water. Keep soil slightly moist but not soggy. The best way is to wait until the top of the soil feels dry to touch - this is time to water again. Jasmines prefer to stay on a dry side; gardenias do not like soil to dry out - keep them slightly moist as long as soil is very porous and well-drained. The main reason of most problems with potted indoor plants is over watering. With experience, you will feel the right balance of moisture in the soil: the brighter the light, the more water is consumed by a plant; the less light, the less frequent you should water.

5. Trimming. In low light conditions, plants tend to become leggy. Trim branches as they become too long: the more you trim, the busier the plant gets. New growth promotes more profuse blooming in many species.

6. Fertilizing. Fertilize indoor plants with slow-release granulated fertilizer from march to November.

7. Insects. Check for insects at least once a month, especially underneath the leaf. If notice any problems (deformed leaves, residue, holes, or tiny insects) - clean the leaves/stems with a solution of warm water (1 cup), vegetable oil (2 table spoons), and a few drops of a dish soap.

8. Fresh air and air humidity. As soon as air temperature gets above 65F, bring your tropicals outside in the sun and fresh air: porch, balcony, outside in the yard. Air circulation is essential for your plant health. Bright light and high air humidity will promote vigorous growth, and lots of flowers for you to enjoy!

Growing sapodilla in container and indoors

Q: I live in northwestern Washington state. I was wondering if I can grow a Sapodilla tree indoors in a container? Are they self-fertile, and which variety do you think would do best in a large container?

A: A: All Sapodillas are self-fertile. They can be successfully grown in pots due to their slow growth rate and compact nature. The most important requirement for successful growing and fruiting is a bright light, other than that it is a very undemanding plant and is not fussy about watering. The best variety for potting culture is Silas Woods which is a dwarf kind. This variety is the most profuse producer, flowering and fruiting nearly year round providing bright light and warmth. Although the fruit are smaller than other varieties and average 3-4" size.
Sapodillas require regular fertilizer applications for good production. We recommend Fruit Festival slow release fertilizer for the best results.

Flavor of Feijoa Superfood

by Onika Amell, tropical plant specialist

Q: What exactly is Feijoa - Pineapple Guava? Does the fruit really taste like pineapple? I am curious to know if it is easy to grow.

A: Feijoa is certainly one of the easiest fruit trees to grow as it does not require much care. It is an attractive, evergreen tree or large shrub with dark green, oval, leathery leaves. It has an abundance of uses in the garden and produces lovely edible flowers and fruit! The fruit is eaten fresh, added to smoothies or fruit salad and is also commonly used to make delicious jams and wicked chutneys. Feijoa fruit go a long way in flavor.
This plant is drought tolerant and will grow in almost any soil type. It loves full sun or partial shade and is wind resistant. A lot of gardeners like to grow it as a wind barrier for this reason. It can easily be shaped into a dense, informal hedge or screen that needs very little pruning. Because of this density, it provides excellent shelter for all kinds of wildlife. Butterflies, birds, and butterflies will all love you for growing Feijoa!
Space the plant five feet apart to create a wind barrier hedge. Heat does no not bother it at all and it will also withstand temperatures to 10 degrees F.
The plant gets its names from the delicious perfume it emits. Some folks seem the fruit taste like pineapple, with a slight minty undertone. Others feel the flavor reminds them of juicy fruit gum! The texture is described as smooth and slightly gritty - almost like a pear, but firmer.
If you prefer to grow this plant as a tree rather than a large shrub, simply remove the lower branches up to one-third of the tree's height over a period of time. The Pineapple Guava can grow up to 15 feet wide and tall. They also do really well as a container plant on patios where you can truly enjoy the lovely fragrance of the fruit. It prefers rich, organic, well-drained soil and will need light fertilization every other month in most soils.

Pretty, pink, edible flowers will wow you from May to June, followed in late summer or fall by the delicious and fragrant fruit. An interesting thing about this fruit is that you don't pick it. It falls to the ground when it is ripe. Or simply place something under your tree, like a tarp, and shake the tree. The ripe fruit will fall off. You can store the fruit in your refrigerator for up to a week. And remember! The fruit of the Feijoa is not only a very rich source of soluble dietary fiber, but also an excellent source of Vitamin C, and very rich in antioxidants. They are also low in calories. Each fruit only holds 55 calories.

Growing Bougainvillea and Plumeria in Florida

Q: I have recently moved from New Jersey to Florida (Orlando area) and I am so excited to start my own Tropical Paradise Garden! A few years ago I visited Hawaii and saw many beautiful colorful Bougainvilleas as well as fragrant Frangipani. Do they grow well in Florida? These are flowers of my dream!

A: Both Bougainvillea and Plumeria grow well in most parts of Florida, especially South and Southwest. Bougainvillea can tolerate some light freeze and can be seen in the streets of Central Florida (young plants require some cold protection for the first year), so it is a very good candidate for your new garden. Keep in mind that unlike in Hawaii, where they bloom year around, Bougainvilleas tend to have a distinctive flowering season which in Florida is winter time - these plants enjoy dry weather that triggers their bloom. To enjoy Bright bougainvillea flowers for a long time, apply balanced fertilizer, prune regularly (this promotes flowering on new growth) and keep established plants on a dry side. Dwarf cultivar Pixie is super compact and can be grown in pots or in a small garden without any pruning! See photo of Pixie on the left.
Plumerias, all-time perfume favorites and symbols of Hawaii, are also residents of many gardens and collections throughout state of Florida. Their cold hardiness is close to the one of Bougainvillea, however keep young plants protected from frost. There are also many new exciting cultivars including multiple "rainbow" colors, and several dwarf varieties, some of them are evergreen - Plumeria obtusa. Plumerias are very undemanding and can stay happy and blooming in a pot and without regular watering. Give them as much sun as possible, and enjoy the fragrance for many months!

Caring of Soursop in container

Q: I have ordered dozens of trees from you and have a question about Soursop. I have a Soursop in a container and ants and aphids are under new leaves. Do Soursop like little water? I water almost everyday living in southern Los Angeles it's been around 76-80F. I spray the aphids and ants off with a mist setting on my hose. They come back every day. They're only on new leaves...

A: First of all, you don't have to remove the ants iа they don't bother you. Ants are good insects, they do not harm plants; most likely they are attracted by a sweet sap - aphid by-product. Ants clean up a plant, and they may even take care of some bad insects.
It is not difficult to get rid of aphids. Use a safe treatment: in a small spray bottle, mix 1 cup of warm water, 1 teaspoon of dish soap and 2 tablespoons of any cooking oil (if you have Neem oil or Horticultural oil - even better, but prepare, they are pretty stinky). Spray the leaves with this solution to a dripping point. Repeat in a few days if needed. This simple remedy will take care of the aphids.
Daily water may be ok for the plant during hot weather, as long as the soil is not constantly moist. Let the surface of the soil get a little dry between waterings.
