Cyrtomium fortunei var. clivicola

Spring-Summer · Indoors

Water during growth

Water regularly as soon as growth becomes apparent until the middle of the summer.

Adopt a regime whereby plants are thoroughly watered every week so that they do not become dessicated. In hot weather watering may need to be more frequent, but less often in cool or moist conditions.

Spring-Autumn · Indoors

Feed with houseplant food

Using a balanced houseplant fertiliser, feed at alternate waterings.

Where food elements are listed as three numeric values on the label representing in order Nitrogen(N)-Phosphorus(P)-Potassium(K), with percentage values for each, choose one where the values are more or less equal.

Spring - late · Outdoors

Feed with slow release fertiliser

Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

This is a simple way to provide a nutrient boost as a single annual procedure.

Spring - late · Outdoors

Feed with sequestrol

If plants are acid loving and grown in soil with little acidity, or in a container, or are watered with limey tap water an annual feed with sequestrol (iron chelate) is highly beneficial. Follow guidelines on the packet. Will also 'blue-up' hydrangeas.

For hydrangeas that have good blue flowers in acid soil, this product can be used with alkaline soil to turn the flowers blue. This is most effective when the soil is neutral or just slightkly alkaline.

Spring-Autumn · Outdoors

Water to keep the soil moist

For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.

Without regular watering some plants never fully regain their beauty.

Winter · Indoors

Water moderately in winter

Water moderately.

Give a small amount of water so that the plant doesn't become flaccid (leaves lose their firmness and may droop or look lifeless), or dessicated, but do not saturate the compost or leave it standing in water.

Outdoors

Water with rain water

This plant needs rain water or soft water (the minerals in alkaline or "hard" water are harmful). This is especially important for plants in pots.

Compost · Planting

Loam based compost for repotting

Repot using any good quality standard compost.

Alternatively prepare a special compost that is best suited to the plant's needs: mix equal amounts of loam (John Innes no. 2 or 3), leaf mould, bark and grit.

Indoor temperature · Planting

15C minimum temperature

This plant requires a minimum temperature of 15 Centigrade.

Indoor plant · Planting

Position in indirect light indoors

Give the plant a position that is cool and light, and away from direct sunshine.
