Growing Exotic Adeniums

Exotic varieties of Desert Roses. Adeniums have many spectacular hybrids. The basic culture is very similar to orchids. A small pot with excellent drainage is a must. Adeniums do not like both over-watering or drying-out. There is a secret how to create a large swollen caudex: raise the plant a bit every time you re-pot it, so that the upper part of roots will be a little exposed. The plant will form more roots that will go down.

To make your plant develop a large swollen base/trunk, you'll need a good quality fertilizer. Fertilizer requirement for swelling up trunks is also used to increase flowering. It shouldn't be too high in nitrogen, the middle number should be the highest (similar to 10-50-10). Never apply fertilizer directly on roots and do not liquid feed when a plant is thirsty: always water first slightly to avoid root burn and leaf drop. Do not wet leaves. Adeniums need lots of light for heavy flowering.

Most hybrids and species start blooming in the spring when the conditions are warm and days get longer, and continue blooming through the fall and winter in warmer climates. Adeniums like a neutral to hard water. Acidic water tends to sour the soil too fast and may cause root rot. Water plants preferably in the early morning, and allow them to drink up throughout the day. Watering can be done daily to every few days. Never allow your plants to sit in a saucer of water, but don't let them to dry out too often - this causes adeniums to go into early dormancy.

Planting instructions for bare-rooted succulent plants. Position the plant in a pot, size of root system. Use only well-drained soil with high content of Perlite and/or sand (cactus mix can be used), water once and keep in warm (75-80F) place in filtered light. Do not water again until soil dries on surface. Once the plant is established and starts growing new leaves (may take a few weeks), gradually move it into brighter light. Then you can start fertilizing it.

Easter Lily Vine creates a fragrant privacy fence of virtually unlimited size

By Ron, South Florida. Easter Lily Vine (Beaumontia grandiflora) is a magnificent woody evergreen climber of unlimited growth potential. A branch of this vine will grow simply until you cut it. I have branches of up to 30 ft. and longer.

I've used two plants to turn a chain-link fence into a privacy screen that is 40 ft. wide by 10 ft. tall, but even a single plant can cover a much wider space if trained properly.

Easter Lily Vine's growth rate is moderate, so it doesn't require constant pruning to keep under control like other vigorous vines. I bought mine in 7 gallon pots, and planted them in the ground immediately. It took about 2 years to completely cover the fence. Since then, I prune it 3-4 times a year.

Keep in mind that these plants are heavy and require a solid structure as support. They twine by nature, but only around items with 3” diameter or more. Mine twined around a near-by lighting pole!

The absolute key in training Easter Lily Vine is to force it to grow horizontally. I recommend planting a young 3 gallon size vine in the ground diagonally, so it grows horizontally. Tie it no more than a foot above ground and let it grow a single branch until the end of the space you want to cover. Then force it to make a U-turn and let it grow the other way. See the following diagram for illustration..

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 “fountain”, 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 4”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 12”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 2”x2” wood beams and two 12”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...
