Do-It-Yourself Support Structure for Dragon Fruit
This interesting do-it yourself project was sent to us by our customer from South Florida. Many tropical gardeners want to grow fascinating Dragon Fruit, and their most common question is - what kind of support I should use for this amazing fruiting cactus? We hope you find this information very useful. Happy Gardening!
Dragon fruit is a terrestrial/epiphytic fruit baring cactus, which may grow fleshy stems up to 30 ft high, given sturdy support. However, downward hanging or horizontal branches stimulate production of flowers at the tips of the branches. Commercial groves in different parts of the world use different method to achieve this. The traditional Vietnamese way is to train the plant into a “fountainâ€, which consists of a vertical central trunk about 8ft tall and a horizontal structure, such as a wagon wheel on top of it to support the horizontal branches (see picture on the right).
This picture served as my inspiration to build my own structure. I used five 4â€x4†10ft wood beams as the trunk, shaped as a cross. I attached the beams to each other with 10†long screws.
I dug a 2 ft deep 12â€x12†hole in the ground and positioned the trunk inside, such that about 8ft are above ground. I covered it with several layers of burlap top to bottom.
The horizontal structure on top is made of four 4ft long 2â€x2†wood beams and two 12â€x12†wood plates to hold them together. I attached this structure to the top of the trunk.
I used old watering pipe to form two rings around the trunk to support the branches. Here is the result!... See step-by-step full size pictures and the rest of the article...

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.

Erblichia or Flor de Fuego - Apricot fragrance and sunny color
Q: I saw this wonderful flower Flor de Fuego on your website and I would like to buy this plant. I am wondering how big this tree will grow and how long will it take until I can smell the lovely flowers? I have a big garden and not much space left, but I still have a few spots available for smaller trees. Also any special care info will be appreciated.
A: Flor de Fuego is a small tree and will fit in any small yard situation. It is very rare in cultivation. This is the newest, most exciting tree to be introduced in the last decade. It said to be one of the most beautiful flowering trees in Central America. It has long narrow leaves and large flowers 6-8" across that smell like apricots. It blooms from late fall through early winter and sometimes through spring. Normally it starts blooming in 2-3 years after planted in the ground. Surprisingly for such a delicate plant, it tolerates poor soils. Once established, it doesn't require any special care other than regular watering and fertilizing during hot months. It does take some effort sometimes to make the tree happy in its new habitat. After planting in the ground, keep your eye on irrigation schedule and do not let soil stay wet, young trees don't like wet feet. In natural habitat, the plant prefers to have a dry period that is beneficial for profuse blooming.

Hot novelty plant for hot Arizona
Q: What plants would you recommend for very hot and dry spot in front of my house that gets full sun all day long? I live in AZ, we recently had a couple good rains but this is going to be it for a long time. It gets so hot during the day that every plant I tried didn't make it. We have a few nice orange trees growing well but I would like to plant something compact, colorful and hopefully fragrant if there is such plant.
A: There is a perfect small size plant for you that is extremely fragrant and yet will be thriving in these conditions. It is the famous Jasmine sambac. It will appreciate dry air of Arizona and will bloom profusely for you in full sun or in partial shade. It doesn't mind heat at all.
For colorful accents, a proven winner is Crown of Thorns - Euphorbia millii. New giant size flower varieties were recently selected in Thailand, and we just received a great selection, look at the colors! These plants don't mind hot sunny location at all. The more sun, the better the bloom! Small plants need regular watering until establish, then once they start developing, they will require less water.
Giant Euphorbia flowers from Thailand are 4-5 times bigger than regular flower euphorbia. Diameter of the flower is around 2". Compare giant flower to normal size - picture on the right.

Growing Vanilla Orchid
Q: I want to buy Vanilla orchid and I wonder if I can grow it in my bathroom by the skylight.
A: Growing Vanilla orchid is no different than other orchids. It is very simple. All that the plant needs is a good light, good air humidity, and good porous support.
Light. Grow Vanilla orchid in a very bright light, but protected from direct hot sun.
Air humidity.The higher the air humidity, the better your plant will grow. Many people grow orchids in a bathroom where these plants can enjoy occasional "humidity treats" after showers.
Growing media. Vanilla orchid cuttings are rooted very often in a regular potting mix with high content of pine bark and/or Perlite, Coconut Husk Chips. Once the little plant is well-rooted and starts developing, it will need a special porous surface to climb on and to attach to with developing aerial roots. A log covered with porous bark is used often. Another option is a piece of wood wrapped with a burlap fabric. In the Nature, this plant climbs up high onto trees and attaches to the bark with aerial roots - at this point, it doesn't need those terrestrial roots any more which may even die off. Climbing a porous support is absolutely necessary for your vanilla for setting buds, flowering and producing vanilla beans. If you are lucky to live in frost-free climate, plant you vanilla by a tree that will provide a shady canopy and a great natural climbing surface (bark). You may see the flowers as soon as within 1-2 seasons!

Seeds germination in summer
Q: What is the best way to germinate seeds in summer? Should I keep trays indoors or put them outside?
A: Summer is the best growing season for plants, and for their propagation. Seed germination process of tropical plants usually benefits from warm, and even hot temperatures, so keeping pots with seeds outside in full or partial sun can be the best way. However some seeds may be more sensitive than others, or require slightly cooler or higher temperature for germination. These are a few tips that may help:
- For seed germination, use only well drained mixes, containing either peat moss or coconut fiber to retain moisture. Some succulents may require adding sand to the germination mix. You may also try our Professional Formula Seed Germination Mix.
- Large tropical seeds, like palms, or seeds of Fabaceae (Bean) family, can be grown in full sun. Their germination will benefit from higher temperatures (up to 90-95F). Make sure to keep soil moist. Cover them well, with 3/4 to 1 inch of soil.
- Fruit seeds (large size) should be germinated either in individual cells or small pots (3-4" diameter).
- Small to medium size seeds can be grown in so-called community pots. Seedlings can be separated after they establish their first roots.
- Tiny seeds should be planted closer to the surface, covered with only 1/4-1/8 inch of soil; some seeds require bright light for germination, so full sun will be a plus. Some small seeds like Ficus for example, prefer to be broadcasted on the surface, uncovered. Put containers with such seeds in bright shade, as you don't want the surface of the soil to dry out.
- Once your seeds sprouted, move them in filtered light - bright to medium shade depending on tenderness of the species. (Gingers prefer shade, while succulent sprouts can stay in brighter light). Regardless of water/sun needs of the species, all young sprouts and first leaves are sensitive to hot sun and may get burned or even killed. Once a baby plant has a few leaves and well-branched root system, you may start moving trays into a brighter light.
- Do not overwater young seedlings, keep soil slightly moist but not soggy.
