Begonia 'Devil White'

Autumn · Planting

Lift before winter

Lift bulbs. tubers or rhizomes in autumn, to keep for the following year. Keep dry and in a frost-free location for the winter. Re-plant in spring.

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-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 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 · Planting

Repot yearly

Repot yearly if grown in a pot. Move it to a slightly larger pot with drainage holes. Some of the old compost can be shaken away, but don't disturb the roots too much.

Be careful to ensure the roots are spread out in the new pot, and that the plant is sitting on compost and not an air pocket. Firm the soil gently, and make sure that the plant sits at the same level above the soil as it did previously.

Summer - early · Outdoors

Apply slow release fertiliser

Apply a slow release fertiliser which is spread around the root area of the 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.

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.

Winter · Outdoors

Water sparingly during dormancy

In its dormant period give very little water, keeping the soil barely moist. Dormancy is likely to be during the winter and the plant recommences growth in early to mid spring.

When a plant enters dormancy the leaves fade, go yellow and then brown. Eventually the whole plant may 'disappear' or unadorned stems may remain.

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

Houseplant compost for repotting

Repot using any good quality house plant compost.

Indoor temperature · Planting

18C minimum temperature

This plant requires a minimum temperature of 18 Centigrade.

Indoor plant · Planting

Position in indirect light indoors

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