Care for a Baobab Bonsai

TopTropicals

Q: How to grow Baobab bonsai properly? How long does it take to shape a nice little bonsai tree?

A: Baobab, or Adansonia digitata, is a unique addition to a bonsai collection. Native to Africa, it has an unusual structure and appearance. Some legends say that the tree was cast down from the heavens and landed upside down, where it began to grow. This story is no doubt a result of its appearance in the winter, when the upper branches of the tree look more like roots than treetops. The Baobab has some specific needs, but if you pay careful attention to its requirements, this tree is not difficult to grow and makes an excellent bonsai specimen.
1. Keep Baobab warm, it is sensitive to freeze.
2. Place Baobab in a bright, sunny window. Baobabs need at least six hours of full sunlight per day, so a window with a western or southern exposure is best. If your house doesn't get enough light, supplement natural light with artificial grow lights. See article Indoor lighting for tropical plants.
3. Water Baobab regularly during the growing season whenever the soil is dry. Never water the tree when it is dormant (dropped leaves).
4. Feed Baobab a good-quality fertilizer about once a month. Apply micro-element solution SUPERFOOD once a month, as well as SUNSHINE-BC plant booster for Bonsai and Caudex plants.
5. Prune the branches of your Baobab bonsai as often as they need it to give the tree the shape you desire, pruning or pinching off branches that are growing at odd angles or are too long. Trim early in the spring before new growth appears.
6. Repot the baobab bonsai every year in Spring. Remove it from pot and trim the roots back by one-third of their length, completely removing any that are damaged or dead. Place it in a container that is twice the size of the root ball and fill the pot with a well-drained soil like Adenium Mix.

It is believed that it takes forever to form a nice shaped tree, up to a few years. However if you provide warmth and bright light, branches grow very quickly, and an experienced bonsai hobbyist can make a unique specimen within 2-3 years. And then, the tree will stay with you for 5000 years - it can be passed from generation to generation!

How to grow a Dragon Fruit

TopTropicals

Q: I want to grow a Dragon Fruit. Should I use cuttings or seed? What varieties do you recommend? How difficult it is to grow? How soon does it start flowering and fruiting?

A: Dragon Fruit, or Pitaya is a highly prized, vining, fruit bearing cactus, extremely unusual terrestrial/epiphytic plant. It has magnificent flowers, stunningly beautiful fruit with an intense color, curious shape, and a delicious taste. The night blooming white flowers can be up to 14 inches in length. The fruit is most often eaten chilled and cut in half so the flesh may be spooned out. The juice is used in frozen drinks and it is in a new Tropicana Twister flavor. It is a must have for any collector or gardener with the flair for the unusual.
It takes 2-3 years for seedlings to fruit, besides the variety pay not come true to seed. We grow our plants from cuttings that are easy to root. We offer many selected varieties, most of them self-pollinating. The plants are ready to flower and fruit this year, or the next year.
Dragon Fruit Cactus is easy to grow, doesn't need much other than strong support, full sun, well-drained soil - adenium soil mix works great - and fertilizer during hot months, and SUNSHINE-Honey applications for growing sweeter fruit. For larger fruit bud thinning is recommended.

Tropical Planting Breaks the Rules. Should I plant in the ground before Winter?

Q: Winter is coming and I still have a few plants I want to plant in the ground. Should I keep them in pots and wait till spring?

A: In subtropical areas, if temperatures don't drop below freezing, you can continue planting in the ground. In fact winter planting has some unique advantages - less heat stress on a plant and root system, mild environment - help the plant to establish better. Besides, no-sweat garden work is much more enjoyable, and you can get done a lot!

Grafted Gardenias: what is the trick?

TopTropicals

Q: I am thinking about buying a Gardenia as a present for my mother's garden in Florida. What is the difference between grafted and non-grafted gardenias?

A: Gardenias are one of our finest shrubs, growing to a height of about six feet in warmer areas of the United States. They have very attractive, shiny evergreen leaves that are about four inches long and, each spring-summer, produce the loveliest of white flowers that are delightfully scented. In areas with alkaline soils, like Florida, only grafted gardenias can be planted in the ground: graft provides nematode resistance, tolerance to poor, sandy and alkaline soils, and healthy, dark green foliage. Grafted varieties have rootstock of Gardenia thunbergia - the most resistant species of all gardenias.

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!
