Growing fruit trees in containers

Will it fruit in a pot? YES! Many tropical fruit trees can be grown in a pot. We get many calls from customers in cooler climates asking if our tropical trees can grow and fruit in a pot. The answer is yes!

Several plants fruit well in pots. Blackberries and raspberries, barbados cherries, blueberries and many more start fruiting even in their 1 gallon containers. We are especially excited about our new Pixie grapes, which are heavily laden with grapes even at only a foot long!

While some plants are small and will fruit easily in a container, others are large trees. For the tree type fruits, we recommend growing only non-seedling plants for pot culture. We have cuttings, air layers and grafted plants that are great options. These have the ability to fruit right away, as they are the same age as the parent tree. Some horticulturists recommend removing the first year fruit to allow the plant to focus on growth and establishing. If the plant is being kept in a pot, this is not necessary.

We also have several dwarf varieties of fruit trees that will thrive in a pot. For avocados, we carry the Wurtz variety which is a dwarf tree... read more...

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!

Mango ID and ripeness

Q: As the World's Leading Authority on Tropical Plants, I hope you can help us out. We obtained a mango tree from a City giveaway, and planted it a few years ago. This is the 1st year it has produced fruit. They are almost all green color, & range from 6-7 inches in length. Attached are a few photos of the tree & its fruit. Please help to identify the type, and how to determine when they would be ready to pick. Or should we just wait until they fall off of the tree?

A: If the tree is grafted, it normally starts flowering within a year after planting. If the tree is over 6 years old and just now started fruiting - chances are, this is a seedling (possible at giveaways) without specific variety. However the fruit looks pretty good size and shape, hopefully it tastes great. You will find out soon!
Based on the pictures, there maybe a few possible choices, including varieties (or their seedlings) Keitt, Rosigold, it can be even Lancetilla if fruit grows bigger than 7" long. The next step would be, wait until the fruit get some color, then it will be easier to narrow down the variety. Also see if there is a lot of fiber or no fiber.
You may wait until at least one fruit ripens on the tree and let it fall naturally - that will be the color (can be all green, but in your case it looks like it's turning yellow blush). After that, you may pick full size fruit before they fall and let them ripen on a kitchen table. Usually once the fruit starts showing color, it is close to ripening. For all-green varieties, just wait till fruit grows to maximum full size. You may also check if the fruit gets softer to touch, then it's ready.

The best Loquat varieties with big, sweet fruit

Q: I'm interested in loquat and read through the varieties you offer but wanted your recommendation. I'm looking for a variety that is big, sweet (not tart) with 1 seed. Of the varieties you offer... Which variety would you recommend?

A: From our experience, the most popular Loquat variety is Christmas. It is an early ripening type hence the name Christmas. Fruits are very large for a loquat, they are bright yellow with a tangy apricot flavor.
Another good variety we recommend is Yehuda - it has a large fruit and very small seed Also, variety Oliver for many years has been considered the best loquat for South Florida. The fruiting season is March to May. It has medium to large fruit. The fruit is very sweet with only one-two seeds.
Loquats are very cold hardy tropical fruit trees, easy to grow, drought tolerant, fast growing. Fruit is great for eating fresh or making jam.

Plant of the Month: Golden Dewdrop - Duranta erecta

Stevie's Pick: what's in bloom?

Our exotic plant grower Steven Gowdy is featuring the most interesting plants he discovers and recommends today while working in TopTropicals greenhouses.

Duranta - Golden Dewdrop - is simply stunning with cascading flowers in abundance. Either it has lavender, blue, or solid white flowers, it is a sight to behold. The popular name Golden Dewdrop is inspired by the clusters of bright orange-yellow berries that follow the flowers, in such quantities that they often cause the slender branches to droop gracefully.
Duranta erecta blooms off and on all year and can be pruned to size as a bush or a standard tree. If let go, it can grow up to 20 feet tall and wide.
Durantas are excellent butterfly and hummingbird attractors. They will complement your tropical garden or a stand alone in your Southern landscape. Great for providing a color contrast in the landscape, they are especially well-suited as a bright-colored background or screening.
White Golden Dewdrop has pure white flowers that appear in loose clusters, and both berries and blossoms are often seen on a plant. This evergreen fast growing shrub spreads and arches to 10 feet tall and wide and is great for live hedges and covering fences and corners.
Variegated variety, also called Variegated Sky Flower, is grown for its summer flowers, and very showy leaves that are dark green with bright white variegation and creamy-yellow margins around the one inch long serrated leaves.. In the summer, cascading clusters of blue tubular flowers appear followed by wonderfully contrasting orange-yellow berries.
In mild climates, Durantas can be in flower nearly year round with flowers and fruit appearing at the same time. It does best in full sun with frequent deep watering and is pretty hardy, to about 20-25F. It is a good choice for espaliers, as a small tree or large bush; all forms benefit from frequent selective pruning. Prune back in late-winter to encourage a more compact shape and strong flush of fresh spring foliage. Requires moderate watering in a well-drained soil.
