How to Grow Strelitzia Reginae in Containers

Inspect the base of a decorative pot and drill a 1/2-inch drainage hole through it, if necessary. Fill the pot with a potting mix comprised of equal amounts potting soil, perlite and peat until halfway from the top. Alternatively, use a commercial potting mix in the pot. Use a pot 4 inches wider than the root ball of the Strelitzia reginae, since the plant prefers to be slightly pot bound. Tamp the potting mix in the pot with your hand to remove trapped air bubbles.

Lower the root ball over the soil and spread the roots in different directions to allow them to spread and grow. Cover the roots with potting mix until 2 inches from the edge of the pot. Tamp the mix with your hand to remove trapped air bubbles.

Place the pot near a south-facing window or a warm spot exposed to indirect but bright light. Maintain a consistent temperature between 60 and 70 degrees Fahrenheit during the day and 10 degrees lesser during the night. Using a thermometer, check the temperature regularly to ensure it remains within the desired range.

Water the potted Strelitzia reginae once every week during the spring, summer and fall. Leave the soil to dry out lightly before irrigating again. Reduce the frequency of irrigation to two times a month during the winter, when the plant is resting.

Feed the Strelitzia reginae a fertilizer specifically formulated for houseplants every two weeks during spring, and once every week during summer. Follow manufacturer's directions for dosage rates and irrigate deeply after applying. Alternatively, feed the plant an organic feed, such as blood meal or manure when it is actively growing. Do not fertilize the plant during the winter.

Place a humidifier near the plant to increase humidity to 60 percent. Alternatively, mist the plant every day, especially during the winter, when the air is dry.

Remove fallen leaves or plant debris from the base of the plant to maintain its appearance and prevent insect infestations or diseases. Clip off spent flowers and damaged leaves using sharp, sterilized clippers. Spray pests such as mealy bugs, whiteflies and aphids with a solution of 2 to 3 tablespoons dish soap mixed in 1 gallon water.
