The orchid family is not only the largest but one of the most diverse plant flowering families in the world. The orchid was one of the first plants to evolve on earth, it was around in the time of the dinosaur, over 120 million years ago. Given the length of time they have been around it shouldn’t be surprising that there are over 35,000 species with hundreds of thousands of hybrids.

The most famous orchid in the world is the vanilla orchid (planifolia). Coca Cola is the largest customer of vanilla, they use the seed for flavoring. Madagascar is the world’s largest producer. Orchids are very beautiful plants and that is why so much time and care is put into growing them. Vanilla on the other hand is grown for its commercial value rather than for its  appearance but it is labor intensive. The vanilla crop is the main source of income for many independent farmers in less developed countries.

The tallest freestanding orchid is Sobralia altissma from the high forests of Peru. It is reported to grow up to 44 feet or 13.5 meters high in optimum conditions. The bright reddish-purple flowers are up to 6 inches or 15 centimeters across and are displayed in spectacular groups of up to 8 flowers per stem.

therefore the amount of scent it produces. Many other Bulbophyllums produce the same carrion scent as this one, but are much smaller.
Native to New Guinea, the pollinator is a fly which is attracted by the unpleasant odor. Last year, I found a live webcam of an opening
flower — the grower couldn’t stand the smell but wanted to see the flowers opening!

Ground cinnamon paste for wounds

Use a paste made of ground cinnamon and a common household glue, such as Elmer’s, to cover and protect wounds on plants so that they will not become infected with fungi. This remedy is for badly damaged plants that you truly want to save after being damaged. The glue will form a  protective barrier and the cinnamon acts as a fungicide.

All purpose cinnamon spray

Cinnamon can also be used in spray formula. Made a mixture of 30 ml of ground cinnamon with 500 ml of alcohol and mix it well. Allow the alcohol mix to steep overnight and then filter to remove the sediment. A coffee filter will do this admirably. Mix 250 ml of the resulting liquid with a liter of water and 10 ml of liquid detergent. Use this as a spray for insects as well as a fungicide.

Always follow the instructions on insecticides

Protect yourself and your plants when applying any kind of product. Some of these products are poisonous to humans or pets as well as to the pests you’re trying to kill. Be especially careful if there are children around and only apply when they are not going to be in the vicinity. It is a good idea to wear protective gloves such as the latex gloves for dishwashing while applying insecticides even if the directions don’t call for them.

Always throw away old potting materials

When repotting, always maintain a clear distinction between old and new potting materials. Throw away any old potting medium which may  contain pests or eggs of pests. One good idea is to spread out old newspaper and fold up and dispose of old medium after it is removed as well as the top layers of paper. You will then have a good sterile environment to put the next plant on. Dip plants in insecticide as well as fungicide before repotting in clean medium and pots.

When you cannot spray plants

An interesting idea I came across the other day was instead of spraying plants, take a plant with insect problems and tie it up in a plastic bag with a new dog or cat flea collar. Leave unsealed in the shade for a day to kill
insects.

To get rid of fungus gnats

To get rid of those annoying little fungus gnats put one of those mosquito larvae killing wafers in water in a bucket. Use this water for your normal watering. The insecticide in the water will take care of the larvae of the
gnats which eat decaying matter in the medium.

Rotate Vandas and sympodials

In order to get your Vandas and Ascocendas to grow upward rather than to one side, rotate them a half turn once a month. This will encourage nice upright growth as well as give the inflorescence a nice presentation.

Color Coded Spray Bottles

Use different colored spray bottles for different kinds of sprays—one for plain water, one for fungicide, one for an insecticide, etc. Using different colors makes it more difficult to spray with the wrong thing. Most garden centers today offer different shape, size and color bottles.
