May: Moving Houseplants Outdoors
Like you, houseplants enjoy a summer vacation outdoors … but don’t rush to take them out. Wait until night time temperatures are consistently above 10°C. You can begin exposing your plants to higher light levels while waiting, moving them from an east window to a south one, for example. When it’s warm enough for them to go outdoors, harden them off. Put them in a protected, shady location for 10 to 14 days before moving them to their final location.
