Is it possible to bring Boston Ferns Indoors and keep as a houseplant over winter? I have 4 magnificent plants on my deck and would love to keep them. What is required for care indoors?
Boston fern (Nephrolepis exaltata ‘Bostoniensis’ ) is a very popular house plant often grown in hanging baskets or similar conditions. It is theoretically a perennial, but is not hardy in southern Ontario. Although the fern may appear totally dead due to frost, it will re-emerge in the spring. In general, the Boston fern likes damp, but not soggy soil that is rich in nutrients. Of the common cultivated ferns, the Boston fern is the most tolerant to drought. The fern thrives best in humid conditions, so when grown as a house plant it becomes necessary to increase the humidity around the plant when relative humidity falls below around 80%. Although outdoors this plant prefers partial shade or full shade, inside it grows best in bright filtered light.
