Houseplants: The Good And Bad About Houseplants
Light and Humidity Requirements for Houseplants

Houseplants can liven up any room. They don't just make offices and homes more attractive, but certain varieties also improve the air quality. They also absorb or refract noise pollution such as sirens, noisy neighbors and loud electronic devices.

To keep your greenery healthy, you need to recreate their natural environment as closely as you can. For instance tropical houseplants thrive in humid, warm conditions, while succulents and cacti adapt to extreme desert temperatures and require little water.

Light Requirements

Light is essential for the development of houseplants. Water, humidity, the right growing medium, and a range in temperatures are all necessary for houseplants to thrive. But light is perhaps the most important factor. Most houseplants thrive in indirect sunlight that is bright, not direct sun. Plants that don't receive enough light could be damaged and may die. A few plants, like succulents and desert cacti are adaptable to intense direct sunlight during the summertime.

You can measure the amount of light an area receives using a light meter or simply by looking at the brightness of your plants. Light meters can be expensive but they let you track the intensity of sunlight throughout the day.

East or south-facing windows are ideal for plants which require filtered sunlight. These windows can provide ample indirect sunlight throughout the majority of the day, as well as direct sunlight for a few hours in the late morning or early afternoon. This light is more intense than the light from an unshaded west-facing window however it may be too much for a plant which prefers partial shade and sun.

Filtered sunlight is sunlight that comes into a room through windows but is softened by curtains, blinds or an awning. It's not as bright as direct sunlight, however it's still sufficient for plants to photosynthesis. If you reside in a northern climate, this type of light is often not available.

Table lamps and floor lamps can provide filtered light to many plants. However they aren't suitable for plants that require full sunlight. They emit more heat than light and are therefore not suitable for plants that are tropical or are fond of the sun.

Certain plants that require bright indirect light can thrive in a North or East Window, but they'll need to protected from rain and wind that could cause the plants to spin around. You can also shelter them with an awning, or another structure that can keep out the harshest elements from the North or East sun.

Water Requirements

The watering requirements for different houseplants is dependent on the climate in which they grow. Tropical plants that live in jungle-like environments prefer a humid, warm environment and regular rain, whereas desert plants, like succulents and cacti, prefer drier soil that only receives watering every few days.

The key to getting the houseplant to thrive is to know its specific needs and to water it in accordance with those requirements. A general rule is to examine the level of moisture in the soil and only water if the top 1" to 2" of the medium for potting is dry. This will prevent the soil from becoming waterlogged and creating root rot.

In general plants that are thirsty will display signs of it by falling leaves, or yellowing them, or being slow to grow new ones. A simple method to test for the moisture of an individual plant is to poke your finger for about an inch into the soil. If it feels damp it is likely safe to put off watering for a couple of days before you water again. Take the pot and check whether it is heavy. If it's filled with liquid, it is. You can also purchase devices that blink, beep or indicate when it's time to water.

Many people opt to plant indoor plants in their offices and homes due to aesthetic reasons. They provide interest and color, soften lines, and improve air quality by absorbing chemicals such as formaldehyde or trichloroethylene that are typically off-gassed from human-made materials. It is important to note that houseplants are not only decorative. They also provide therapeutic benefits and can lower stress levels.

The majority of indoor houseplants thrive in glazed or ceramic pots than in terracotta ones. They will also grow faster in the summer and spring than they do in winter and fall. When choosing a watering can make sure you choose one that has an adequate control over the spout, so that you can direct the water at the soil's surface and not soak the leaves, which could cause fungus to flourish. If you can't get rainwater, tap water will do so long as it's left to sit for a couple of days to allow the chlorine evaporate.

Temperature Requirements

A majority of the houseplants we grow are natives to subtropical or tropical climates. To thrive indoors, they require a humid, warm, and moderately humid climate. Most plants thrive in temperatures between the 58-86 degree Fahrenheit range. Temperatures that are too cool can slow growth, while temperatures that are too hot can cause wilting and other problems.

Flowers and tropical plants, such as philodendrons (philodendrons) palms (peace lily plants) as well as hibiscuses, bromeliads, enjoy warm temperatures during the daytime. This boosts photosynthesis and creates sugars and starch to help plant tissues expand. They require cooler temperatures at night to save energy.


Succulents, including cacti and the well-known fishhook barrel cactus as well as the string of pearls, need very warm temperatures to thrive. They can survive temperatures as low as 40 degrees Fahrenheit, but they will not thrive in the event of sudden temperature changes.

The best method to ensure that your houseplants are healthy is to ensure that they are in a sunny area that is warm during the day and moderately cool at night. This is especially important during winter, when the sun appears lower in the sky and the light levels decrease by as much as 50 percent. You can prevent your plants from becoming too dark by moving them to a window with more light or by adding additional lighting.

During the winter, surface soils is more likely to dry out because of lower temperatures. When it's time to water, make sure to use warm (not cold) water to avoid causing shock to the roots. Water your plants early in the morning so that they can absorb the water before temperatures drop at night.

Many kinds of houseplants are at risk of dying from a sudden temperature change even the most well-known. It is particularly hazardous for tropical and subtropical species like philodendrons, banana trees and palms. Even some succulents, such as bear paws and agaves can be destroyed by sudden temperature changes. It is recommended to bring these plants inside prior to when the temperatures drop outside and gradually adjust them to indoor conditions, so they can adapt to the transition.

Humidity Requirements

Many houseplants require high humidity levels. Many houseplants are native to tropical regions that have higher humidity levels. Some are more adapted to the dry climate of deserts and forest underbrush and cannot adapt to low humidity and temperatures indoors. This is especially true for orchids, aroids and other plants like haworthias.

cool house plants is the capacity of air to hold water vapor. It is measured using an scale ranging from zero (dry) to 100 percent (saturated with moisture, like fog). cool house plants for homes is 30-50 percent. A lot of common houseplants can survive within this range. However those that require high humidity may suffer and drop buds or leaves due to the fact that they're not able to hold the humidity in the air.

If the humidity is low, plants will become dehydrated as the stomata shrink and they are unable replace the lost water with fresh carbon dioxide which is vital for photosynthesis. This could cause the plant's death. When humidity is very low, the first indication of this is a dry appearance as the plant begins to dehydrate. Other symptoms include wilting or browning of the leaves.

One method to increase the humidity around a plant is to place it on a tray stuffed with gravel and water. The plant will gain the humidity it requires by evaporating water. It is vital to clean the tray on a regular basis to prevent mold and bacteria from breeding in the stagnant water and causing damage to the roots of the plant.

A plastic bag can also be used to increase the humidity of a plant. Be sure to put wooden stakes into the pot to keep the plastic from the plant. Make types of house plants that it isn't in direct sunlight, which can harm the leaves of the plant. It is crucial to open the plastic from time time and look for excessive condensation, which can suggest that the temperature of the air is too high.

Other ways to increase the humidity of plants include placing it in bathrooms and kitchens where there is usually more humid air than in other rooms in the home. It is also beneficial to group plants with high humidity in the same space, as they will benefit from each other's faster transpiration rates, creating a tiny area of greater humidity around them.
