Horticultural Classification Codes

Horticultural Classification Codes are often given to genera which have a large number of species or cultivars. They are used to categorise cultivated plants based on specific, shared characteristics such as shape, colour, size or flowering time, and can be displayed as letters or numbers

For example:
Dahlia ‘Sunset Kate (Sin) = Single flower
Rosa ‘Marigold’ (HT) = Hybrid Tea: Dessert apples are sweet and juicy and are best eaten fresh and raw

How to Grow

Cultivation

Thrives in deep, fertile, moist but well-drained soil in a sunny, sheltered position. Will not thrive on very acid soils, shallow chalk soils or with shade for more than half the day. Tree height will depend on the rootstock and training method. May require fruit thinning to improve fruit size and quality. See apple cultivation

Propagation

Propagate by chip budding in late summer, or grafting in mid-winter. Plants grown from pips are unlikely to resemble the parent

Suggested planting locations and garden types

City and courtyard gardens
Cottage and informal garden
Patio and container plants
Wildlife gardens
Edible fruit

Pruning

Prune according to chosen training method. See apple pruning

Pests

May be susceptible to aphids, including rosy apple aphid and woolly aphid, apple sawfly, fruit tree red spider mite, codling moth, apple leaf-mining moth and other caterpillars

Diseases

May be susceptible to blossom wilt, brown rot, fireblight, honey fungus and powdery mildews. This cultivar has some resistance to apple canker and apple scab
