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.

...Looking for a handsome, unusual fruit tree for container culture with healthy and flavorful fruit? Or simply want an easy fruit tree that is hardy and undemanding? Psidium friedrichsthalianum (family Myrtaceae), the Costa Rican Guava or Cas Guava, is a perfect small guava tree that can be very rewarding. In Nicaragua it is called "Guava for Drinking" or "Fresco de Guava". Despite the tartness, the flavor is excellent with passionfruit and pineapple tones and is much more pronounced than the subtle flavor of the common Guava. These fruits are very much a part of the culture and cuisine of Costa Rica. Also it has been successfully grown in California now and can be grown in many subtropical regions or as a container plant - "condo" fruit tree...

Best tasting white guava

Q: What's your best tasting white guava?

A: Our favorite white Guava is Viet Nam variety that is also very rare and hard to find. The fruit is very large, up to 6"in diameter, the pulp is very sweet and somewhat crunchy. The seeds are small which makes it more pleasurable to eat out of hand.
Another great feature of this variety, it stays compact and branches do not get leggy, unlike most guavas. It can be easily grown in a container, trimmed to the desired size and it will produce fruit under proper care.

Another cool variety is Indonesian, it also has a large round fruit and very few seeds to compare with others.

And last but not least, if you prefer soft fruit to crunchy, the Peruvian variety is a great choice. The fruit is pear-shaped.

Remember to provide plant food for good production, especially if grown in a container.

How to get a Jasmine to bloom.
Caring for jasmines as container plants during Winter

TopTropicals.com

Locate the jasmine plant where it will receive bright filtered light at least six hours every day.

Put a few pebbles in a shallow plate or tray and pour fresh water over the pebbles. Set the pot on the pebbles, but don't let the water level touch the bottom of the pot. This increases the humidity in the air around the jasmine. Keep the plant away from wood stoves, heat vents and radiators.

Water the jasmine when the top 1/2 inch of the soil feels dry. Don't let the soil get soggy, and never let the pot sit in water. Water the plant sparingly during the winter.

Feed jasmine twice a month between Spring and early Fall, using a granulated slow-release, or water-soluble houseplant fertilizer mixed at half strength. Don't fertilize during the winter months.

Prune the jasmine as needed to maintain the desired shape. Never prune in winter, as the plant will be preparing to bud.

Encourage the jasmine to bloom by putting it in a cool room at night for four to five weeks during Fall to Early Winter. The plant should get plenty of sunlight during the day, but during the night, move it to a pitch-dark room where the temperature is between 40 and 50 degrees F. After four to five weeks, leave the plant in its regular, daytime location. The plant should start blooming in mid-Winter to early Spring.

TROPICAL GARDENING: How to grow Brugmansia (Angel Trumpet) in the ground outside.

TopTropicals

Q: I recently moved from New Jersey to Florida and I brought with me my Brugmansia that I used to have as a house plant. Can I plant it in the ground now?

A: Angel Trumpet - Brugmansia - is a very popular container plant valued for its large, stunning fragrant flowers. Originated from South America, it will be happy to grow in tropical to subtropical climate outdoors. These are a few useful tips to get the most out of this beautiful plant:
1) Light. Plant it in full sun - the more sun, the more flowers you get, although Brugmansias tolerate shade. If the plant was previously grown in container indoors, to avoid leaf burn, keep it protected with a shade cloth or simply white sheet for a while and gradually open to adjust to full sun.
2) Soil and fertilizer. Use fertile soil with lots of organic matter (add compost to existing soil). It must be very well drained, Angel Trumpet won't tolerate waterlogged conditions. Plant it on a little "hill" elevated 3-4"above the surrounding area. Brugmansias are very heavy feeders. Once the plant is established, fertilize on regular basis with Slow Release Fertilizer - a handful once a month.
3) Water. Water daily until established. Once the root system is well developed, the plant is drought tolerant and won't require too much care. But at the beginning, watch the leaves - the lush foliage droops quickly if the plant is thirsty.
4) Plan space. Brugmansia is a short tree, but it needs a lot of room to spread branches with its heavy hanging flowers. Think 12" wide and maybe almost as much tall.
5) Support. Being widespread plant, Brugmansia can be blown with strong winds. Stake with strong support until established.
6) Propagation. Brugmansia is one of the few plants that propagates with semi-woody cuttings; soft green cuttings usually have little success. Other than that, it is pretty easy!
