It is the time of year when we think about bringing plants indoors that have been outside on the deck, patio or by the pool for the summer. There are a few things we can do to help these plants adjust to this change in environment.

Many plants that can be brought indoors for the winter months are considered tropical. Examples are the beautiful, tropical hibiscus, ficus (or fig tree), Christmas cactus, elephant ears and banana trees. These plants have had nearly full sun all summer or certainly much brighter conditions than they will have indoors. It is best to acclimate these plants to the lower light levels by moving them to a shady area for a couple of weeks before moving them indoors. If this acclimation process does not take place, sensitive plants may drop some of their leaves and possibly flower buds when they are brought inside. A gradual adjustment is always best. Outdoor temperatures in the 40’s can also be harmful to some varieties causing them to shed leaves.

Plants that have enjoyed the summer outside may have gathered “hitch hikers” which we don’t want to bring indoors. Some of these critters are very small insects that go undetected for a while but then become an issue in a month or so. They are difficult to control especially when we do not want to use pesticides in our living areas. Examine the plants closely for insects. Aphids, mites, scale and mealybugs are some of the more common pests. A good hosing down with a strong stream of water will help eliminate some of them. If any remain, spray with a nontoxic, insecticidal soap or a natural compound like neem oil. Make sure to cover both sides of the leaves and all stems and branches. Some larger critters come indoors in the soil. A good way to control them is to set the potted plant in a laundry tub filled with water for 15 minutes to completely saturate the soil. (Do not leave the plant in the water for more than 30 minutes or damage to the root system can occur.) Remove the pot from the pan of water and let it drain completely. Do this about a week before bringing the plant inside.

This is also a good time to check the root systems to see if the plants are root bound and need transplanted to the next size container. If the roots are very “thick” or compacted, the roots should be pruned slightly and the plant repotted.
