Many forms of Escallonia make an excellent dense evergreen hedge, although it will flower less freely due to the additional pruning required. To form a hedge plant 2ft (75cm) apart.
Although many forms of this fast growing shrub can reach a height and spread of up to 10ft (3m). They respond well to pruning, so will do just as well in the small garden.
Water thoroughly during dry weather until well established. Mulch with organic matter in spring. Feed with a general fertilizer weekly during the flowering period.
Severe frost can cause damage, so protect plants in a hard winter.
Prune back shoots that have flowered in the autumn and cut out any straggling shoots and dead or damaged growth. Trim hedges in the autumn after flowering is finished.
Flowers form on the old wood of the previous year's growth, so excessive pruning will affect flowering the next year.
Virus diseases may cause mottling, streaking, or distorting of the leaves.
Take 4-6in (10-15cm) semi-hardwood cuttings in mid-summer to mid-autumn. Use a rooting hormone and root in a slightly heated propagator or in a cold frame. Escallonia cuttings root quickly and should be potted up as soon as roots develop.
Can also be propagated easily from layering.
