Moving houseplants outdoors for the summer can significantly boost their growth and vigour, but it requires careful planning to avoid damage from sun, wind, and pests, according to houseplant expert Tara Soloway of Plantd Life.
Benefits of an Outdoor Staycation
In early June, many gardeners send their houseplants on a summer staycation to a back porch, deck, or balcony. The extra sun and fresh air provide a real boost, especially for sun lovers like crotons and flowering plants. Soloway notes that she has even seen potted fruit trees bear fruit after being placed outside.
However, she cautions that outdoor environments are very different from indoor windowsills, and certain principles must be followed to ensure success.
Acclimatize Gradually
Houseplants do not react well to sudden change. Instead of moving them outside all at once, acclimatize them over several days: start with two hours on the first day, then four hours the next, and gradually increase exposure. This helps plants adjust to the increased light and temperature.
The biggest change is light intensity. Even plants that thrive in a south-facing window can suffer sunburn if placed in direct outdoor sun for too long. Monitor the chosen spot over a full day to understand its sun pattern—dappled morning light may become broiling by afternoon.
Adjust Watering and Protect from Wind
Watering needs increase dramatically outdoors due to sun, warmth, and air movement. Hanging plants may need daily watering during hot spells. Use a water meter to check moisture levels regularly; summer rain is usually insufficient.
Strong winds can dry out soil and leaves, and can cause physical damage such as torn leaves, broken branches, or even toppled plants. Place plants in a sheltered location or anchor them to something sturdy. Bring them indoors on very windy days.
Watch for Pests
Outdoors, houseplants become vulnerable to garden pests like aphids, spider mites, earwigs, and slugs. Inspect plants daily and keep insecticidal soap or other control methods ready. Early intervention prevents infestations from taking hold.
With these precautions, houseplants can enjoy a rejuvenating summer outdoors and return indoors in autumn with renewed strength for the winter ahead.
