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.

Spring-Autumn · Indoors

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 - late · Outdoors

Feed young plants with slow release fertiliser

Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.

This is a simple way to provide a nutrient boost until the plant becomes well established.

Spring-Autumn · Outdoors

Water in dry periods

Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.

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.

Winter - late · Planting

Prune to maintain the plant

Remove and dead or damaged branches or any growth that looks very untidy. Trim the plant back if necessary to keep it within bounds.

Outdoor planting · Planting

Add root growth stimulant to the planting hole

Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.

Compost · Planting

Loam based houseplant compost for repotting

Buy container or house plant compost that is loam based if possible (i.e. is based on John Innes compost number 2 or 3. This contains more fertiliser and is better suited to established plants.

John Innes no. 1 has the lowest level of fertiliser and is used for seedlings and young plants, so is generally used where plants will be 'potted on' after a number of weeks.

Indoor temperature · Planting

0C minimum temperature

This plant requires a minimum temperature of 0 Centigrade.

Compost · Planting

Multi-purpose compost

Use a good quality peat-free multi-purpose compost when growing in pots and containers.

Position in moderate light / some shade

This plant is happiest in a position with part or light shade, near a sunless window or some distance away from a sunny or bright window. It should not be exposed to full sunlight.
