Most house plants that are used for decorating the interiors of homes are tropical. Here are a few tips on how to take care and grow these special plants.

Although tropical houseplants are generally hardy, they do need some amount of care for their optimum growth.

Most novice growers have trouble with matters like watering, light, fertilization, and diseases that affect the tropical houseplants. So, here are a few tips that will help you to take care of your precious plants.

Watering

Inexperienced growers have a tendency to over water houseplants. This results in spotting of leaves and rotting of roots, which ultimately leads to the death of plant. It is better to check the soil, and if it feels dry, only then water the plant.

Usually, these plants just need to be watered about once a week when the weather is warm.

Even though tropical plants thrive best with rainwater, tap water can be used as long as it is kept out overnight to allow the chlorine to evaporate. Then, the water should be poured into the pot, avoiding the leaves.

Humidity must also be considered. While all plants need humidity for optimal growth, tropical plants with their delicate and slender leaves are more sensitive to lack of moisture in air, and need extra humidity. So, they need to be misted at least once every day.

Lighting

Inexpert growers also have a tendency of thinking that tropical house plants need the most direct and brightest sunlight, which is not true. In fact, direct sunlight, particularly through a window facing the south, can burn the leaves of tropical plants.

This is because light passing through the glass pane of the window gets magnified, resulting in the heat being more intense. The best light for tropical plants is the one coming through south or north facing windows having sheer curtains. Curtains lessen the light intensity of the light.

Fertilizers

Most commercially available fertilizer for tropical house plants consist of phosphorus, which helps in the development of the roots; nitrogen, which boosts growth; potassium, which also helps the roots to grow; and calcium, which helps the plant to absorb potassium and phosphorus.

While it is best to fertilize in the spring, but it is also advisable to lightly fertilize all through the year, about once or twice each month. Time-release fertilizers are best for doing this; hence, use this kind in the spring.

Diseases that Affect Tropical Houseplants

Tropical house plants can become susceptible to disease if they get wrong amounts of fertilizer, water, or light. They are most vulnerable to be attacked by fungi.

If your plants are over watered, have inadequate light, subject to too much humidity, grown in a potting mix that is unsterilized, it causes fungal growth. Fungi usually grow and spread very swiftly, resulting in the destruction of all your tropical plants.

Some of the most common symptoms of a fungal infection are the shriveling of the tips of the leaves along with dark strips; the shedding of infected leaves; a whitish-gray matter forming on the soil; and the leaves getting black, brown or white spots.

The best methods of countering a fungal attack are: using a fungicide to treat the plant; reducing the watering; lowering the humidity; and increasing the ventilation.

If the affected plant needs to be repotted, the soil should be sterilized first. One of the best ways to sterilize the soil is to put the soil in a baking pan with a potato inserted in the center. This should be baked at 350°F. The soil gets sterilized once the potato is done.

Best Tropical Plants to Grow

Plumerias, Heliconias, and Gingers are some of the plants that grow well in humid and warm conditions. If winter temperatures are very cold, they can be grown indoors. The Frangipani, or Plumeria, which comes in seven types of varieties, is a fragrant and beautiful tree.

Heliconias have lovely flowers and huge leaves, which can have a dramatic effect. Gingers too have a heady scent, and are available in a number of varieties. They grow the best in fertile and moist organic soil.
