Light and Humidity Requirements for Houseplants

Houseplants can add a sense of vivacity to any room. They don't just make homes and offices more attractive, but certain varieties also improve the air quality. They absorb or reflect sound pollution such as sirens, buzzing neighbors and loud electronics.

To ensure that your plants are healthy, you need to replicate their natural habitat as best you can. For example, tropical houseplants thrive in warm, humid conditions, while succulents and cacti can be adapted to desert temperatures and minimal water.

Light Requirements

The requirements for light for houseplants are a vital element of their growth. Houseplants need many different conditions to thrive including humidity, water, proper growing medium, and a range of temperatures however, the most important aspect is light. The majority of houseplants thrive in bright indirect light but not direct sunlight. Plants that don't receive enough light may be damaged and eventually die. A few potted house plants are adapted to direct sunlight during the summer months, like desert succulents and cacti.

You can measure the amount of sunlight an area receives using a light meter, or simply by watching how bright your plants are. Light meters are costly however they allow you to see how the intensity of the sunlight changes throughout the day and throughout the year.

East or south-facing windows are perfect for plants that require filtered sunlight. These windows offer bright indirect sunlight during most of the day and some hours of direct sunlight in the late morning or early afternoon. The light is more intense than the light from an unshaded west-facing window but it could be too excessive for identifying house plants that likes partial sun and shade.

Filtered sunlight is sunlight that enters a room through windows but is softened by curtains, blinds or an awning. This light is not quite as bright as direct sunlight, but it is still sufficient for most plants to photosynthesize. If you live in a northern climate, this type of light is usually not available.

Incandescent light sources, such as table lamps or floor lamps can also provide filtered light to most plants, but they are not ideal for plants that require full sunlight. They emit more heat than light, which makes them unsuitable for a lot of tropical or sun-loving plants.

Certain plants that require bright indirect lighting can thrive in the North or East Window, but will need to protected from rain and wind that can cause the plants to spin around. They can also be sheltered with an awning or other structures that block the harshest elements of North or East sun.

Water Requirements

The watering requirements for different houseplants are dependent on the conditions in which they are growing. Tropical plants that thrive in jungle-like conditions love the humid, warm climate with regular rain. Desert plants, like cacti, prefer moister soil, drier soil and periodic watering.

The key to allowing a houseplant to thrive is to be aware of its particular needs and to water it according to its requirements. A general rule is to examine the level of moisture in the soil and only water when the top 1" to 2" of the medium is dry. This will stop the soil from becoming saturated and leading to root rot.

Generally speaking plants that are thirsty will show symptoms of it through dropping and/or yellowing leaves or by taking a long time to produce new leaves. To determine the moisture level of the plant, simply insert your finger in the soil around one inch deep. If the soil feels moist it is best to rest for a few days before you water again. Another option is to pick up the pot and see if it is full of water it will feel heavy for its size. You can also purchase devices that beep, indicate or light up to alert you when it is time to water.

Many people choose to incorporate indoor plants into their offices and homes due to aesthetic reasons. They add interest and colors, soften lines and improve air quality by absorbing chemicals such as formaldehyde or trichloroethylene which are usually 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.

Most indoor houseplants will grow better in ceramic or glazed pots rather than the terracotta. The summer and spring months will see them grow more than fall and winter. If you're seeking a container to water your plants pick one with a spout that's easy to control. This will allow you to direct the water directly towards the soil without soaking the leaves, which can invite fungus. If you're not able to find rainwater tap water, it can be used as long as it is left to sit for a couple of days in order to let the chlorine vaporize.

Temperature Requirements

The majority of the houseplants that we plant are native to subtropical or tropical climates. To thrive indoors, they need a humid, warm, and moderately humid and moist environment. Temperatures ranging from 58 to 86 degrees Fahrenheit are ideal for the majority of plants. If temperatures are too cool, they can cause a slowing of growth, while temperatures too hot can cause wilting and other problems.

In general, flowering and tropical species, such as philodendrons, House plants common palms, peace lily inside house plants plants common houseplant; try here,, hibiscuses and bromeliads, prefer warmer temperatures during the daytime that increase photosynthesis, which produces sugars and starch that allow plant tissues to grow. The plants require cooler temperatures at night to conserve energy.

Succulents, like cacti, as well as the common fishhook barrel cactus as well as the string of pearls, need very warm temperatures in order to thrive. They can survive temperatures down to 40 degrees Fahrenheit however they are not able to thrive in sudden temperature changes.

The best way to keep your houseplants healthy is to ensure they are in a sunny area that is warm during the day and cool at night. This is particularly important during the winter months when the sun is lower and light levels can drop by as much as 50%. To avoid your plants becoming too dark, move them to an area with a brighter view or add additional lighting to the room.

During the winter, soils on the surface can dry out more quickly because of lower temperatures. When it's time to water, use warm (not cold) water to avoid causing shock to the roots. It is also a good idea to water your plants early in the morning, to ensure that the water is taken up before the temperatures begin to fall at night.

Many types of houseplants are at risk of dying due to a sudden temperature drop even the most well-known. It is especially dangerous for tropical and subtropical species like philodendrons, palms, and banana trees. Even succulents like agaves or bear paws can be killed by sudden shifts in temperature. It is recommended to bring the plants indoors prior to the outdoor temperatures start to fall. Then, gradually adjust the plants to indoor conditions so that they can adapt.

Humidity Requirements

Many houseplants require a high level of humidity. They could be from tropical regions where humidity levels are much higher, or they may be adapted to the more dry conditions of the desert underbrush or forest and don't adapt well to typical indoor temperatures and low levels of humidity. This is particularly true for aroids and orchids, however, other plants, such as haworthias and cacti, as well as succulents.

Humidity is the measure of the ability of air to hold water vapour. It is measured from zero (dry), to 100 percent (saturated, like fog). The average relative humidty for homes is between 30 and 50 percent. Many common houseplants can survive in this range, but those that require high humidity are likely to suffer and may start dropping buds or leaves that aren't able to support the amount of moisture present in the air.

When the humidity is low, stomata could close and plants are not able to replace the water loss by fresh carbon dioxide which is vital for photosynthesis. This can eventually lead to the death of the plant. The first sign that humidity is low is the appearance of the plant as it becomes desiccated. Other signs include wilting and browning of the leaves.

Set the plant on a tray filled with gravel and water to increase humidity. The water that evaporates will give the plant the added humidity it needs. It is important to empty your tray frequently to prevent the growth of bacteria in the stagnant water. This could cause damage to the roots of your plant.

A plastic bag can be used to boost the humidity in a plant. Make sure to place wooden stakes in the pot to keep the plastic away from the plant. Make sure that it is not in direct sunlight, which can burn the leaves of the plant. It is essential to open the plastic from time time and check for excessive condensation, which could indicate that the temperature of the air is too high.

Place the plant in the kitchen or bathroom where the air is generally more humid than in other rooms of the home. It is also helpful to group plants together with high humidity in the same location, since they can benefit from each other's faster transpiration rates, creating a small space of increased humidity surrounding them.
