WHERE TO BUY COLNEY CHERRY TREES

Colney is not often to be found in your local garden centre but is available online on (almost exclusively) Colt rootstock.  It can be bought as both a potted tree (generally more expensive) all year round or as a bare-rooted tree from October to March (cheaper). We would recommend buying bare-rooted.

CONDITIONS FOR GROWING COLNEY CHERRIES

The following are the key rules for growing this variety, click here for more detailed information about growing and pruning cherry trees:

• Plant and grow in a full sun position.
• The best time to plant Colney is in late autumn to early winter. It can be planted at other times of year but will require watering more frequently to ensure it establishes well.
• Plant the tree to the same depth as it was in the pot. If planting bare-rooted trees you will see a natural soil mark just above the roots which indicates the correct depth for planting.
• Spread an 8cm / 3in layer of mulch around the base of the tree but not touching the main trunk. A mulched circle of about 1m / 3ft will be sufficient. This will retain moisture in the soil below and greatly help the tree to establish well.
• Water very well immediately after planting.
• Stake the tree for the first two years of its life on a Colt rootstock. If planted on Gisela 5 rootstock the tree will require staking for its life.
• In the first summer after planting the tree, water well if conditions become dry.
• Prune Colney in the first year according to the suppliers instructions. Prune annually in later years, soon after the fruit has stopped being produced which will be about the end of July for Colney. See our detailed article on pruning cherry trees.
• An annual mulch in late Spring will help to retain moisture and an even supply of water.
• If any pests or diseases appear treat them as soon as possible. Consult our cherry tree pest and disease page for detailed information on identifying and treating problems.
