Spider plants naturally grow in tropical regions in the south and west of Africa. Their tropical origins make them well suited to growing indoors, but they can live outside as perennials in zones 9 through 11. Spider plants can be brought outdoors for the summer in other climates and returned inside when the weather becomes cold. Managing direct sunlight is a challenge when growing spider plants outdoors. Plants in nature can take on limited amounts of direct light, but houseplants are not accustomed to the more intense light of the outdoors and are often unable to handle direct sunlight.
When To Put Spider Plant Outside
Move spider plants outdoors when the outside temperature is above 60 degrees Fahrenheit. Spider plants can handle chilly temperatures, but growth will slow down. Very cold temperatures can damage or even kill the plant. Slowly transition the plant outdoors for just a couple of hours a day before leaving it outside full-time.
When To Bring Spider Plant Indoors
Use the air temperature as the guide when returning a spider plant indoors. Move the plant back indoors before the temperature drops below 60 degrees Fahrenheit. The risk of stunted growth or damage increases when temperatures dip below 60 degrees, so it’s best to err on the side of caution. Since the conditions inside a home are more consistent, the plant can be moved directly inside without slowly transitioning it to its new location.
Inspect the plant for signs of pests and diseases several weeks before moving it inside. Treat any issues while the plant is outside to reduce the risk of harming plants inside. Consider spraying the plant with horticultural oil as a preventative measure, even if there are no signs of an issue.
Caring For Spider Plant Outdoors
Spider plants living outdoors for the summer need partial shade. Initially, place the plant in full shade and gradually increase the plant’s exposure to sunlight. Spider plants can handle 3 to 4 hours of sunlight when acclimated. Water the plant when the top few inches of potting soil are dry.
Place the plant in a protected area like a screen porch or covered patio to avoid damage from wind and severe weather. Plants with rain access should be in a container with drainage so excess water can flow through the container.
