HOW TO GROW BROMELIADS THE EASY WAY

Bromeliads are native of South America. Growing them are quite easy as long as they are provided with the basic growth requirements. They have several genera. Some are giants while some are tiny. Many of them though are in between.

This plant is very versatile and sturdy. They can be grown even without soil. They require very little insecticides and minimal fertilization.

They are also prized for their colorful foliage. Some have also very long-lasting flowers that are not only colorful but also have usual shapes.

Common genera of Bromeliads

• Aechmea
• Billbergia
• Cryptanthus
• Neoregelia
• Nidularium
• Tillandsia
• Guzmania
• Vriesea
• Ananas or ornamental pineapple

How to Propagate Bromeliads

The most common way of propagating bromeliads is through separation of their suckers or pups as soon as

they are 1/3 the size of the mother plant. Usually, bromeliads produce a lot of pups (sometimes more than 10 pups) as soon as they flower. Others produces suckers or pups before the produce flowers.

To produce more suckers from your mother plant, you have to remove the suckers or pups as soon as they are ready for separation. If you’ll not remove them, only few pups will come out.

Other method of propagating bromeliads is by seeds. But not all bromeliads produce seeds. Some Aechmeas readily produce seeds which could be grown in fine chopped fern chips or chopped coconut husk that are constantly kept moderately moist.

The problem with those grown by seeds, because it will take more than a year to grow the seeds into a medium- size plant. This will delay your venture for a faster way of producing more plant especially if you’re on commercial production.

Use the right potting medium

You should select a potting medium that easily drains and does not easily deteriorate. If you have a fern tree in your country, you can chopped them. They are ideal as potting medium.

You can also use a mixture of coconut coir fiber and coconut coir dust. You have to use more coconut coir fiber so that the medium will not breakdown fast. You should repot the plant once the medium becomes soggy.

If the above potting mediums are not available, use a chop dried coconut trunk. If you’ll use the fresh ones, dry them before using.

Where to place your bromeliads?

To get a more attractive foliage colors of your bromeliads, place them under proper light conditions. You can attain this by placing them under a three layers of fishnets. Guzmanias and vrieseas generas requires more shady conditions.

You can readily see if your bromeliads are under proper light conditions. If under too much shade, the colored ones will become green. If placed under too much sunlight, their leaves becomes scalded or bleached.

Another important requirement in growing bromeliads is proper air ventilation. Good air circulation will bring out the best color of the plants and will also prevent fungal infection that could eventually result in rotting.

To attain a proper ventilation, place your plants atop a bench. If that is not possible, seat them atop inverted clay pots so they will be at least one foot above the ground.

Plant nutrition

Fertilize your bromeliads so they will grow faster and healthier. Don’t over-fertilize them in order not to lose their bright colors.

A sign of over-fertilization, the leaves becomes too long and they will not look attractive.

Use a slow-release fertilizer. If not, use the ordinary urea or complete fertilizer and apply them to the potting medium. Or you can apply foliar spray.

Remember this, to get a better result, fertilize only at half the usual dose.

PLANTS USED AS INSECTICIDES

Plants have so many uses either as foods, feeds, medicines, and above all as insect repellents in the form of insecticides. In fact, almost anything that the human race needs always depend on plants.

Insecticides that come from plants are much cheaper, less toxic as against the synthetic chemicals, and besides plant insecticides are environment friendly.

The followings are among the plants that can be used as insect control:

1. Tobacco – Nicotiana tabacum. The leaves are pounded or pulverized together with mint ad tomato leaves, pepper, garlic and onion.

Formulation:

• Extract the sap or juice from the powdered material. For every cup of sap, mix one cup water. Filter and set aside.

• For easy and efficient spraying of the mixture, the following materials are needed: two eggs, eight tablespoon of oil, two cups water, two tablespoon vinegar, one pack cigarettes, and one bar laundry soap.

• To prepare, place the cigarettes in an empty gallon can. Add the two cups of water and boil for 15 minutes. Remove the heat and filter the solutions. Add the oil and vinegar. Mix the eggs ad beat until the mixture is sticky. This will make the insecticides stick to the plants. Soap helps make spraying easy and even.

2. Makabuhay – This plant is a natural pesticides. This has been proven to be effective against brown plant hopper, green leafhopper, and rice stem borer.

Procedure:

• Chop the leaves and scatter them in the rice fields or vegetable areas.

• Ground makabuhay leaves are broadcasted at the rate of two kilos per square meter on rice seedbeds 10 days after sowing.

• This procedure has proven makabuhay as toxic as broadcast carbofuran.

• Toxic effect lasts five to seven days after application.

3. Derris roots – Derris plant or “Tubli” in some parts of the Philippines especially in the Visayas and Mindanao provinces. It has a biodegradable insecticide known as rotenone.

Procedure:

• Powder or make a liquid form of the root sap and sprinkle or spray directly into the plants.

• Liquid form should be sprayed to the plants affected with pea aphids, corn borers, bean beetles, mosquitoes, and houseflies.

3. Aromatic Herbs – Mint, oregano, and other aromatic herbs traditionally used as spices may be planted around garden plots to repel insects. Experts recommends that for every 100-square-meter bed, 8-10 marigolds should be intercropped in the garden with 20-25 garlic or onion bulbs to discourage pests from attacking plants.

Procedure:

• Chop-fine aromatic herbs such as onion, garlic, horseradish, red pepper, mustard, mint.

• Strain the solid and add a quart of water and liquid detergent.

• Mix with onion brew (Brew contains onion roots, stems and leaves).

• The brew is sprayed generously over plants infested with insects. If the brew ferment, it has been found to effectively repel insects.

There are lots of plants that are used as insecticides. I will be publishing them in future issues. Just stick to me.
