Check whether a plant is male or female (and plant both if berries are wanted) before assuming a lack of berries is a cultivation problem.

Care

Light

One of the better flowering/berrying shrubs for a shadier spot.

Water

Standard shrub watering.

Soil

Acidic to neutral, humus-rich, moisture-retentive soil; tolerates some lime but does best on acidic ground or ericaceous compost in pots.

Pruning

Minimal — trim to shape after flowering if needed.

Feeding

An ericaceous feed in spring, especially in a container. Yellow leaves on a skimmia are nearly always lime in the soil or the water rather than hunger, and an ericaceous feed helps with both.

Propagation

Semi-ripe cuttings in late summer with bottom heat. Remember that most skimmias are single-sexed: a cutting from a female plant gives another female, which will need a male nearby if you want berries.

Month by month

Months change with the climate: in southern Italy tomatoes go out two months earlier than in England.
