Houseplants can be easy to grow if you understand your plants needs and your home environment. Here are some the basic requirements for growing plants in your home.
Household light varies in intensity, depending on the season and the exposure. South-facing windows provide the most light: direct sunlight within 2 to 3 feet of the window; bright, indirect sunlight up to 5 feet from the window; and semi-shade up to 8 feet away from the window. East and west-facing windows provide some direct light up to 3 feet and indirect light up to 5 feet away. East windows get sun in the morning, west in the afternoon. North-facing windows provide semi-shade up to 5 feet away.
Light intensity changes with the season. Plants that fare well in a southern exposure during the winter may have to be moved to an east- or north-facing window in summer when the light is more intense. Remember to keep both sides of your windows clean; dirty windows can block up to 50% of the light. Most plants grow toward sunlight, so remember to rotate the pots ¼ turn every few weeks so that the plants will grow evenly.
Even if there are no natural light sources available, many plants will survive with other sources of light. Light can come from indirect sunlight or artificial lights specifically designed for growing plants.
Having lush vibrant houseplants can transform any living space. But where you place your plants in relation to windows can make all the difference in how well they thrive. So what window is actually best for houseplants? The optimal window for plants depends on several factors. Read on for a complete guide to choosing the best windows to promote healthy plant growth.
Sun Exposure: The Key Factor in Window Selection
The most important consideration when selecting windows for houseplants is sun exposure. Plants need sunlight for photosynthesis, the process by which they convert light into energy and grow Different types of houseplants have different light needs Choosing windows that provide suitable levels of direct and indirect sunlight is crucial.
South-facing windows receive the most intense direct sunlight throughout the day. Plants that require high or very high light levels, like cacti and succulents, do best in south-facing windows. Just be sure to place them a few feet back to avoid scorching.
East-facing windows get bright morning light. They’re a good option for plants with moderate to high light needs, like philodendrons, dracaenas and ferns. West-facing windows get direct afternoon and evening sun. They work well for low to moderate light plants like pothos, Chinese evergreens and peace lilies.
North-facing windows get the least direct sun, but still provide steady ambient light. They’re the best spot for low light plants such as calatheas, pileas and cast iron plants. Rotate plants regularly so all sides get even sun exposure. Also, keep windows clean to maximize incoming light.
Other Factors to Consider
Sunlight levels play the biggest role, but other factors like temperature, humidity and airflow at different windows also impact plant health. Here are some additional things to consider:
-
Seasonal variations – Adjust plant placements as seasons and light levels shift. Move sun-lovers away from south windows in intense summer sun. Rotate plants to compensate for lower winter light.
-
Temperature – Most houseplants grow best with daytime temps of 65-75°F and nighttime temps of 55-65°F. Avoid drafty windows in winter and hot afternoon sun in summer.
-
Humidity – Humidity is lower near windows in winter. Help tropical plants by grouping them together or using a pebble tray for extra moisture.
-
Air circulation – Good airflow prevents pests and diseases. Crack windows open occasionally or use fans to prevent stagnant conditions.
-
Supplemental lighting – Grow lights can compensate for inadequate natural light from any direction. Timed LED plant lights work well for low and moderate light plants.
-
Window treatments – Sheer curtains diffuse intense direct sun. Insulated drapes help conserve heat in winter. Close drapes at night to block drafts.
Finding the Sweet Spot
The most important factors in selecting the best windows for houseplants are the specific needs of the plants and the light levels provided. But also consider the whole environment – temperature, humidity and airflow. With a little trial and error and adjustments over time, you can create thriving indoor plantscapes in windows of any orientation. The ideal spot just needs the right balance of sun, climate control and care.
Signs that plants are getting too much light:
- Leaves burn and have scorched patches.
- Leaves wilt.
- Leaves look washed out.
- Leaves dry out completely and fall off.
There are plenty of variables that determine how much water a plant needs. Large plants tend to need more water than small plants. A plant that is flowering or actively growing (producing new green shoots) needs more water than it does during a dormant (resting) stage. Plants tend to need more water during the warm summer months than during the cool winter. Plants in sunny locations need more water than plants in shade. Clay pots are porous and so dry out faster, while plastic pots are better at retaining moisture. Some plants prefer dry conditions, while others demand constant moisture. It all depends on the plant you select, how you plant it and where you place it.
Signs that plants are not getting enough light:
- Leaves are smaller than normal.
- Leaves are pale.
- Plant exhibits leggy growth.
- Lower leaves yellow and fall off.
- Variegated leaves turn green.
- Plant doesnt flower.
What Plants Are Good For North-Facing Windows
FAQ
What is the best window position for plants?
South-facing windows provide the most light: direct sunlight within 2 to 3 feet of the window; bright, indirect sunlight up to 5 feet from the window; and semi-shade up to 8 feet away from the window. East and west-facing windows provide some direct light up to 3 feet and indirect light up to 5 feet away.
Which window is the best for plants?
Increase your indoor gardening success by matching plants to your indoor light conditions. An east- or west-facing window provides enough light for most indoor plants. Keep those that need brighter light within two feet of the window. Move them to a south-facing window in winter if needed.
Are east or west windows better for plants?
Many plants can grow lush and beautiful in East-facing direct morning sun, which is more gentle than West or South sun. If you need plants to put to the side or a few feet away from your window, sort by East-facing filtered light below.
Which window side is best for plants?
South-facing windows are a plant lover’s paradise, as they receive the maximum amount of sunlight. The intense and direct sunlight that streams through these windows is a boon for plants that thrive in full sun conditions.
