Spring-Autumn · Indoors

Feed with houseplant food monthly

Give the plant a balanced houseplant feed monthly while in growth.

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.

Water regularly during growth

Water regularly while in growth.

Adopt a regime that means the 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 · 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.

Spring - early-mid · Planting

Divide when too large

The plant can be divided if it becomes too large or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in pots or planted in the ground.

Summer - early · Outdoors

Feed a general fertiliser

Where plants have moderate needs for nutrients, they can simply be given a general feed, fairly early in the growth season so that the growth has plenty of time to harden off before the cold weather.

Give plants a general boost with the application of a general purpose fertiliser which is spread around the root area of the plant, with amounts as directed on the feed label.

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.

Indoors

Mist some plant varieties

Some plant varieties within this genus require misting. It is best to look up your specific plant for guidance.

Indoors

Water some varieties differently

Some plant varieties within this genus have additional requirements for water. It is best to look up your specific plant, or the species it belongs to for watering guidance, and/or check the label.

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), fine bark and grit.

Indoor temperature · Planting

Minimum temperatures vary

Plant varieties within this genus have differing requirements for minimum temperature. It is best to look up your specific plant for guidance, and/or check the label.

Indoor plant · Planting

Position in indirect light indoors

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