The houseplants add color, beauty and fresh air into a home, as long as they provide adequate care. The fact that they can adapt to closed environments does not mean that fundamental factors for their existence and growth, such as light, water and fertilization, can be dispensed with.

Sunlight plays a very important role in the growth and development of plants, and several of their activities are determined by the time they are exposed to that form of energy. The case of plants grown indoors is no exception; for example, most flowering species need to be within 3 feet of a sunny window for best production.

Also, it should be noted that, in general, plants may require 12 to 16 hours of exposure to light per day.

Water is another factor to consider when growing houseplants , as overwatering is a leading cause of illness and death for these specimens.

It is important to water with water at room temperature. A few drops of ammonia can be added to a liter of water that will be used on indoor plants to help improve leaf color and stimulate overall growth.

In late fall, most houseplants demand moderate watering until light duration and intensity begin to increase with the arrival of spring.

Sometimes, the leaves of an indoor plant can show the formation of small drops on the foliar epidermis, as if it were perspiring, even when it has not been watered. This phenomenon, known as guttation, is an attempt by the plant to rid itself of excess water. This can make it vulnerable to disease-causing bacteria, so reduce the amount of water that is being given to the plant, especially in the winter months.

In terms of ambient humidity, most of these plants grow best when relative levels exceed 50 percent.

Indoor plant care: Frequent fertilization and air renewal

Periodic fertilization is another required task if you want indoor plants to grow more vigorous and healthier, so it is advisable to feed them frequently during most of the year, except in winter, since the species grown inside a house are usually sensitive to excess fertilizer during that season. It should be remembered that during the winter season the plants enter a state of rest.

Finally, it is convenient to open the doors and windows when the temperatures allow to give the house a change of air, something that will benefit both people and plants. Also, to reinvigorate the latter, about 6 millimeters of the top of the soil can be removed and replaced with fresh potting soil.
