Moving plants outdoors during the warmer spring and summer months provides many benefits. Plants typically grow faster, their foliage can become more colourful, the increased humidity levels keep them hydrated, and a breeze can strengthen stems and roots.
Over time, plants become accustomed to the conditions of their current environment. While moving them outside can be favourable, it is important to acclimate plants to the change in environmental conditions in order to minimize stress.
Acclimate /ak-luh-meyt/
verb
To accustom or become accustomed to a new climate or environment; adapt.
When Should I Move My Plants Outside?
Our rule of thumb is to wait until the long weekend in May to move your plants outdoors. This is when warmer temperatures are most consistent. Indoor plants require a minimum evening temperature of 10 degrees Celsius in order to remain healthy. If you notice the weather forecast is showing temperatures below this benchmark then bring your plants back indoors, to a covered porch, or a garage.
How Long Does it Take to Acclimate?
The time period can vary based on the plant variety and location; however, it’s safe to say one week is enough time to allow your plants to adjust to the natural elements.
High Light Plants
Even sun-loving plants require time to build a tolerance to more intense light, wind, and humidity conditions. For the first couple of days, place your plant in an area with indirect light that is sheltered from wind and rain. For the next consecutive days, transition them to a space with direct morning light or partial shade. Finally, your plant should be ready to move to a location that meets its higher light requirements.
Indirect Light Plants A majority of the tropical plants we sell would fit in this category. In their native environments, many tropical varieties grow under dense tree canopies where only sparse, filtered light can reach them. To transition these types of plants outdoors, simply place them in a location with indirect light conditions such as a covered porch or under the shade of a tree. A spot that is sheltered from wind and rain is also preferred.
Other Tips
Ensure that pots have drainage holes if plants will be in areas exposed to rain.
If you are expecting storms and heavy rainfall, make sure plants will be protected. Too strong of winds can rip or damage leaves, stems, or tip over plants.
Bleached foliage or browning of foliage indicates that your plant is getting too much sun.
You will probably have to irrigate more frequently when your plants are outside.
