Pteris is a large genus with several species that have become familiar house-plants.
Pteris cannot tolerate dryness at the roots. Water plentifully at all times, giving enough to keep the compost thoroughly moist.
Apply a half strength standard liquid fertilizer once every month in Summer or every 2 weeks depending upon the type of potting mixture. The more frequent feedings are required for plants in a peat-based mixture.
Re-pot in Spring only when the existing container has been filled with roots using soil or peat-based compost.
Propagation by division of the clumps in Spring. Keep the young plants warm and in shaded after division until they are established.
Like all ferns Pteris enjoys reasonably good but indirect light and a compost which is kept constantly moist but not soggy.
Cut away the older outer fronds of Pterises if they become shabby-looking.
Humidity can be provided by spraying their foliage daily with tepid water or by standing them on a tray of wet pebbles or put in outer container with damp peat between the two.
Peat or soil-based compost.
Less than 2 percent of the insects in the world are harmful. Most are beneficial.
