Light and Humidity Requirements for HouseplantsThere's no place a plant can't enliven and, not only do they make offices and homes appear more inviting, but certain varieties improve the air quality. They absorb or reflect sound pollution like sirens, buzzing neighbours and loud electronic devices.To keep best house plants , you need to replicate their natural habitat as closely as you can. Tropical houseplants, like thrive in warm, humid conditions. Cacti and succulents on contrary are suited to dry, desert temperatures with minimal water.Light RequirementsLight is essential for the growth of houseplants. Houseplants require many different conditions to thrive. These include humidity, water, appropriate growing medium and a range of temperatures, but perhaps the most important factor is light. Most houseplants grow best in indirect light and not direct sun. Plants that don't get enough light may become damaged and eventually die. Only a handful of plants, such as succulents and desert cacti are adaptable to intense direct sunlight in the summertime.The amount of sunlight a room gets can be measured with an instrument for measuring light or simply watching the brightness level of your plants. Light meters can be costly however they allow you to monitor the intensity of sunlight throughout the day.South-facing or east-facing windows are ideal for plants which require filtered sunlight. These windows provide ample indirect sunlight throughout the majority of the day, and intense sunlight for some time in the late morning or early afternoon. This light is more intense than the sunlight from an unshaded west-facing window but it could be too for a plant that likes shade and partial sun.Filtered sunlight is sunlight which can enter a space through windows, but is softened by blinds, curtains or awnings. This light isn't as bright as direct sunlight, however it is still sufficient for the majority of plants. If you live in a northern climate this kind of light is usually not available.Floor lamps and table lamps can provide filtered light to many plants. However, they are not suitable for plants that require a lot of sunlight. These lights emit more heat than light, and are therefore not suitable for plants that are tropical or love sun.Some plants which require bright indirect light will thrive in the North or East Window, but will require protection from rain and wind which can cause the plants to spin around. They can also be protected with an awning or other structures that block the harshest aspects of North or East sun.Water RequirementsThe requirements for watering various houseplants depend on the conditions in which they thrive. Tropical plants that thrive in jungle-like conditions love the humid, warm climate with regular rainfall. Desert plants, such as cacti, prefer moister soil, with drier soil, and only periodic watering.To get a houseplant growing it is important to know its requirements and water it accordingly. A good rule of thumb is to examine the level of moisture in the soil and only water when the top 1" to 2" of the potting medium is dry. This will prevent the soil from becoming waterlogged which can lead to root rot.A plant that is thirsty exhibits signs of thirst by dropping or yellowing leaves, or slowing the growth of new leaves. A simple method to test for the moisture of an individual plant is to poke your finger for about 1 inch deep into the soil. If the soil feels moist it is best to wait a few more days before watering again. Take the pot and check if it feels heavy. If it's saturated with liquid, it will be. You can also purchase devices that beep, indicate or flash to inform you when it's time to water.Many people decide to plant indoor plants in their offices and homes for aesthetic reasons. They provide interest and colors, soften lines and improve air quality by absorption of chemicals like formaldehyde and trichloroethylene, which are often off-gassed by man-made materials. It is important to remember that houseplants aren't only decorative. They also provide therapeutic benefits and can lower stress levels.Most indoor houseplants do better in glazed or ceramic pots rather than terra-cotta ones. Spring and summer will see them grow more than winter and fall. When selecting a watering container make sure you choose one that offers good control over the spout, so that you can direct the water to the soil's surface and not soak the leaves, which can invite fungus. If you can't get rainwater tap water, it will work so long as it's allowed to sit for a few days in order to let the chlorine vaporize.Temperature RequirementsThe majority of the houseplants we plant are native to subtropical or tropical climates. For houseplants to thrive, they require a humid, warm environment. Most plants thrive in temperatures ranging from 58 and 86 degrees Fahrenheit. Temperatures that are too cool can slow down growth, whereas temperatures that are too hot can cause wilting and other problems.The tropical and flowering plants, like philodendrons (philodendrons), palms (peace lily plants), hibiscuses, and bromeliads, like warmer temperatures during the daytime. This increases photosynthesis and produces sugars and starch to help plant tissues expand. They require cooler temperatures at night to save energy.Succulents like the cactus that grows in a fishhook barrel, string of pearls and cacti require warm temperatures to thrive. They can withstand temperatures as low as to 40 degrees Fahrenheit but are not able to thrive in sudden temperature changes.It is recommended to place your houseplants in a sunny, warm sunny area that is moderately cool in the night and warm during the daytime. This is particularly important in the winter months, when the sun appears lower and light levels can decrease by up to 50%. You can prevent your plants from getting too dark by moving them to a window with more light or by adding additional lighting.In the winter, soil surface can dry faster due to colder temperatures. When it's time to water, use warm (not cold) water to avoid shocking the roots. Water your plants early in the morning so that they can absorb the water before the temperature decreases at night.Many kinds of houseplants are at risk of dying from sudden temperature changes, even the most popular. easy house plants that are tropical and subtropical such as philodendrons and palms, are particularly vulnerable. Even succulents like bear paws and agaves can be killed by sudden fluctuations in temperature. It is recommended to bring these plants inside before the outdoor temperatures begin to decrease and gradually adjust them to indoor conditions so that they can adjust to the transition.Humidity RequirementsMany houseplants require high humidity levels. They may come from tropical regions where humidity levels are higher, or they may be adapted to the more dry conditions of the desert or underbrush of the forest and don't adapt well to typical indoor home temperatures and low levels of humidity. This is particularly true for orchids and aroids, but also other plants such as haworthias and cacti, as well as succulents.Humidity is the capacity of air to hold water vapor and is measured on a scale from zero (dry) to 100% (saturated with moisture, like fog). The average relative humidity for homes is between 30 and 50%. Many common houseplants will be able to survive within this range. However house plants that require high humidity can suffer and drop buds or leaves due to the fact that they can't support the moisture in the air.If the humidity is low, plants can be dehydrated because the stomata shrink and they are unable to replace the water lost with fresh carbon dioxide, which is vital for photosynthesis. This can eventually kill the plant. If the humidity is low, the initial sign of this is a dry appearance, as the plant is dehydrated. Other signs include wilting and browning of the leaves.Place the plant in a tray with gravel and water to increase the humidity. The water that evaporates will give the plant the added humidity it needs. However, it is important to clean the tray regularly to prevent mold and bacteria from growing in stagnant water and damaging the plant's roots.A plastic bag can also be used to increase the humidity in a plant. Be sure to put wooden stakes in the pot to keep the plastic from the plant. Make sure that it is not in direct sunlight, which could cause burns to the leaves of the plant. It is crucial to open the plastic from time time and look for excessive condensation, which would indicate that the temperature in the air is too high.Other ways to increase the humidity of plants include placing it in bathrooms and kitchens, where there is often more humid air than in other rooms of the home. It is also helpful to group plants with high humidity in the same location, since they will benefit from each other's higher transpiration rates, creating a tiny pocket of higher humidity surrounding them.
