"Japanese box" hedge - Buxus japonica

Buxus "Japanese box" is an excellent hedging plant for low to medium sized hedges.  Most "Japanese box" hedges are grown to around 50cm tall, although larger hedges up to 1.5 m can be grown (given some years).  "Japanese box" does not have showy flowers, but has lime green foliage that stands out in the garden very well.  Best soil type is a loam, however they will also grow in sandy soils.  Plants will grow in clay soils, but growth will be slower.  "Japanese box" grows at good pace, not too fast or too slow.   For the best shape, prune every 6 weeks.  "Japanese box" responds to nitrogen fertiliser very well, but the use of general purpose NPK is suggested to build healthy plants. 

"Japanese box" grows well in semi-shade to full sun conditions.  It is suitable to grow in Temperate, Warm temperate, Mediterranean (with summer watering) and Subtropical climates.  It will also grow in cool temperate regions, but growth speed is reduced.    Not suited to areas with heavy frosts, as the foliage will be damaged.  "Japanese box" grows thickly and is suited to low hedges, it is superior to English box in many ways, particularly in the growth department.   Plants are reasonably hardy, but will not stand up to extended droughts.  In most suitable climates the plant will grow with normal, natural rainfall and will not usually need extra watering. 

The secret to growing a good low hedge with Japanese box is to use enough plants when planting the hedge.  To develop a hedge of around 40cm high, plants should be planted around 20cm apart (or closer if possible).  "Japanese box" is not suited to areas with salty coastal winds.  Plants will live around 25 years.

To care for your Buxus "Japanese box" hedge plants,  plant them in a good well drained soil in a sunny position.   Plant using a good organic planting mix and use slow release fertiliser.   Water well to establish a good root system.   "Japanese box" can grow quite quickly in spring and autumn with a small dose of NPK garden fertiliser.   Good foliage colour is developed by using fertiliser in spring or autumn or use liquid fertilisers throughout the year..   Aphids can be a problem pest in spring, but are easily controlled.
