5. Some plants are more adaptable to temperature changes than others. These plants, known as “thermophilic,” are capable of adjusting their metabolic activity and physiological processes to cope with varying temperatures.
Acclimating Indoor Plants To Outdoor Conditions
When the warm summer months arrive, it’s a great opportunity to bring your indoor foliage plants outside. However, it’s important to acclimate them gradually to the new outdoor environment to ensure their health and well-being. Plants have evolved outdoors and can benefit from the fresh outdoor air, but sudden changes in temperature, light, and humidity can shock their systems.
To acclimate your plants, start by placing them in a shady area outside for an hour or two. Over the course of 7-10 days, gradually increase their time outside, allowing them to adjust to the new environment. This slow approach helps avoid overwhelming the plants and allows them to adapt to the intensity of outdoor sunlight.
While some plants can handle direct sunlight, others prefer indirect light. For those that prefer indirect light, it’s essential to ensure they are shaded by 10 am, even if other plants can handle direct sun in the morning. Regardless of their light preferences, all plants benefit from a gradual introduction to outdoor conditions over at least 10 days.

- Gradually increase their time outside over 7-10 days
- Ensure plants are shaded by 10 am if they prefer indirect light
- All plants benefit from a gradual introduction to outdoor conditions.
Factors To Consider Before Moving Plants Outside
Before bringing your plants outside, consider the following factors to ensure their optimal health and well-being:
-
Temperature: It is generally safe to move plants outside when outdoor temperatures consistently stay above 50°F (10°C). If nighttime temperatures fall below this threshold, it is advisable to bring the plants indoors and return them outside when temperatures rise. Exposure to temperatures below 50°F can hinder growth for a few weeks, while temperatures below 35°F (1.6°C) may cause leaf damage. Although freezing temperatures can kill leaves, the roots usually survive if the exposure is short-lived. Keep an eye on the weather forecast and be prepared to protect your plants if a sudden cold snap occurs.
-
Watering frequency: Outdoors, various factors such as temperature, light exposure, and wind speed will affect your plants’ water needs. Higher temperatures, light levels, and wind speed will cause plants to utilize water more quickly, while lower temperatures, light, and wind will slow down their water consumption. Additionally, plants in low humidity will need to be watered more frequently, while those in high humidity will require less watering.
Ensure your plants’ health by paying attention to these factors, adapting your care accordingly, and providing them with the necessary conditions for growth.
Watering And Humidity Tips For Outdoor Plants
When it comes to watering outdoor plants, there are several guidelines to keep in mind. Firstly, the frequency of watering will vary depending on the temperature, light exposure, and humidity levels. It’s crucial to check the soil moisture daily until you become familiar with how your plants react to their new outdoor environment and changes in weather.
In general, a thorough soaking of the soil is required, but the amount of water needed will depend on environmental conditions. However, if your region experiences rainfall of 1 inch or more, it can replace a regular watering session. Nevertheless, after heavy rainfall, it’s essential to check the soil’s moisture levels and adjust your watering schedule accordingly since rain can leach nutrients out of the soil.
Humidity levels also play a role in watering frequency. In regions with high humidity, tropical plants may not require additional misting, as the ambient humidity is sufficient. However, in areas with low humidity, such as the Southwest or desert climates, misting the plants may be necessary to simulate the moisture they would typically receive indoors.
Protecting Plants From Extreme Weather Conditions
While plants can benefit from being outdoors, they need protection from extreme weather conditions. Gentle and steady rainfall is generally safe for plants, but severe wind and rain can damage foliage. It is important to ensure that plants are shielded from such conditions to prevent harm.
Additionally, sun-loving plants can be susceptible to sunburn if not properly acclimated to intense sunlight outdoors. If you notice sunburned leaves, they can be pruned off and new leaves will form. Moving the plant to a shadier area can also help it recover from sunburn.
Maintaining And Monitoring Plants’ Health Outdoors
Regularly monitoring plants’ health is crucial when they are outside. Checking the leaves for pests and diseases should be part of your routine, as outdoor conditions can attract unwanted visitors. Additionally, after heavy rainfall, it is advisable to fertilize your plants regularly, as nutrients can be leached out of the soil.
When placing plants outside, make sure to remove them from any saucers or trays to allow water to drain freely. This prevents waterlogging and ensures optimal root health. By maintaining and monitoring your plants’ health outdoors, you can enjoy their beauty and reap the benefits of having them in your outdoor living space.
In conclusion, when bringing your indoor plants outside for the summer, it’s important to:
- Acclimate them gradually
- Consider temperature thresholds
- Adjust watering frequency to environmental factors
- Protect them from extreme weather conditions
- Regularly monitor their health
By following these guidelines, you can help your plants thrive in their new outdoor environment and enjoy their beauty throughout the summer months.
