Often termed Common Spruce or Norway Spruce. Has orange/brown bark when young which turns to purple/grey when mature. Foliage is dark green, flattened, needle-like. Often grown in dwarf form (Little Gem/Maxwellii).
STYLE : Suited to all styles except broom.
WARNING : Dense foliage makes spruce particularly prone to red spider mite and spruce aphid attack.
REPOT : Every 2 years in spring, before bud-break. Less frequently, as required, for older, larger trees.
SOIL : Free draining soil : 30:70 grit:organic.
PRUNE : Prune branches in autumn when they will bleed less resin.
PINCH : Prune new shoots hard in spring but leave second flush untrimmed.
WATER : Water well in growing season, sparingly in winter. Do not let soil dry out. Tree also benefits from misting in summer.
FEED : Balanced feed bi-weekly until late summer, then nitrogen free in autumn.
