Temperature: Comfortable house temperatures are fine. Can be grown outside as long as temperatures do not go below the low 40's.

Feed: Quarter strength of any soluble fertilizer when new growth is present. Miracle Gro® or equivalent works well.

Water: ...more ferns are harmed by overwatering than holding back on the water. Water well then allow to dry lightly before watering again. "Cobra "® is quite water sensitive and it must get plenty of air to its roots between waterings.

Potting Mix: Should have some peat to hold fertilizer salts and moisture, but the mix must drain very well. Dolomite lime supplies Ca and Mg helps keep good color.

Pest Control: Quite pest-free. Most pests can be brushed off with a Q-tip and alcohol or just plain water if found early enough.

Pot size: 6" to 8" pots or a piece of Redwood or Cedar bark. Plastic pots dry out more evenly but clay looks great.

Repotting: Can stay for a very long time in a pot. Problems arise when it is so pot bound that it requires water too often. Your fern can then be moved up to a larger pot, or divided quite safely into several new pots.
