Growth habit: Deciduous, spur-bearing orchard tree of moderate vigour; trained as a bush, cordon, or espalier. Suited to restricted forms and warm walls, which help it ripen properly in cooler climates.

Apple 'Cox's Orange Pippin' is a hungry evergreen fruiter with specific needs — a dedicated citrus feed, switched between summer and winter formulas, keeps it cropping and green.

How often should I feed apple 'cox's orange pippin'?

Feed in early spring with a balanced, potassium-rich fertiliser and mulch with compost or rotted manure. Avoid heavy nitrogen, which makes Cox even more prone to scab and canker. Keeping the tree moderately, steadily fed rather than pushed hard reduces disease problems. Feed in early spring with a balanced, potassium-rich fertiliser and mulch with compost or rotted manure. Avoid heavy nitrogen, which makes Cox even more prone to scab and canker. Keeping the tree moderately, steadily fed rather than pushed hard reduces disease problems. In practice: a summer citrus feed regularly (often roughly fortnightly) from spring to autumn, switching to a winter citrus feed at a reduced rate over the colder months — citrus feed year-round, unlike most container plants.

What strength of feed for apple 'cox's orange pippin'?
