Prunus ‘Kojo-no-mai’ is a fantastic deciduous shrub with elegant, layered branches and zig-zag twigs.

Prunus incisa 'Kojo-no-mai' Growing Guide 

Planting 

If planting directly in the ground, incorporate plenty of garden compost or well-rotted manure in the hole when planting. 

Hillier tip: For detailed planting advice see our guide to planting large shrubs and trees

If growing in a container, the most typical size of pot when your first purchase the plant is 17cm (although larger, more mature plants are also often available). Over time, this is a plant that can grow to around 4 feet high and wide if the container is big enough (it would naturally reach this size grown directly in the ground). A pot around 35cm-40cm in diameter will support a good-sized P. 'Kojo-no-mai' so long as the plant is well watered and fed. When re-potting, always put some crocks or stones in the bottom of the pot to help with drainage.

Hillier tip: We recommend moving up pot size in stages, re-potting every couple of years as the plant grows - jumping straight from a 17cm to 35-40cm pot may look a little strange until the plant grows to fill it. This approach also allows for the addition of some new compost for the roots to grow into. Potting from a 17cm to a 25cm-27cm pot is a good first step.

Pruning 

Prune lightly in summer after flowering, removing dead, diseased or crossing branches and shaping as desired. Prunus incisa ‘Kojo-no-mai’ will tolerate a harder prune, allowing you to keep its shape small and compact if desired. 

Watering 

Water well for the first few months after planting – particularly during any dry spells.
