About this plant
Often seen as a houseplant in Britain and Ireland, this makes a handsome specimen if there is space in a conservatory or greenhouse. The individual fronds which can be up to 1.5m (5ft) in length, make a rigid arch. They grow out from a fat rather bulbous chestnut coloured stem that gradually elongates over the years. The plant has male and female forms and is unlikely to flower 'in domesticity.' The female plant produces an orange cone, the male also produces a yellow cone. The plant thrives outdoors in gardens that have a Mediterranean climate and it tolerates sea air and even salt spray. The Japanese sago palm is not a palm but a cycad, a 'living fossil' related to Gingko bilboa. It is unlikely to exceed 2m (7ft) in height and spread in these latitudes but it can achieve 8m (26ft) under natural conditions.

Spring
Spring - late · Indoors
Apply slow release fertiliser
Apply a slow release fertiliser which is spread around the root area of plants soon after they have come 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-Autumn · Indoors
Water to keep soil moist
Water regularly, but do not leave the plant sodden or with water in a saucer at its feet. It likes to be dry during the winter months.
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.
Spring · Planting
Repot occasionally
Repot occasionally if grown in a container. Move it to a slightly larger pot with drainage holes in the bottom. Shake off some of the old compost, but don't disturb the roots too much.
Make sure the roots are spread out and that the plant is sitting on compost and not an air pocket. Firm the soil gently, and ensure that the plant sits at the same level above the soil as it did previously.
Summer
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
Winter-Spring · Indoors
Water lightly in winter
The soil should remain just moist during the cold months when the plant is not in growth. Trickle a little water onto the soil surface every couple of weeks if the soil is dry. Do nothing if it is moist.
The roots remain active in winter and benefit from small amounts of moisture so they don't become completely desiccated.
Planting & general
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
5C minimum temperature
This plant requires a minimum temperature of 5 Centigrade.
Indoor plant · Planting
Position in a bright spot, no direct sun
Give this a bright position away from the direct sun, especially direct sun at the height of the day. (Direct sunshine is too hot and can burn the leaves.) Move the plant to a brighter position in the room during winter and early spring.
