Very popular variety, vigorous and heavy cropping – producing almost double the yield than that of other varieties. Large pale green berries, smooth skinned with an extremely sweet flavour. Essentially a culinary variety but can also be eaten fresh. The fruit is superb for cooking with as its stays firm, it also freezes well, maintaining shape and colour. Invicta is resistant to mildew and leaf spot. Eventual height: 1½m (5ft). Eventual spread: 1m (3ft). Cropping season: late July/August. Self fertile.
Plant 1.5m (5ft) apart in rows 2m (6ft) apart. Likes an open sunny or lightly shaded frost-free spot, sheltered from strong winds. Prefers a slightly acid, moist but well-drained fertile soil.
Soak the root-ball before planting. Plant in a hole twice the diameter of the root-ball or pot. Mix an organic soil improver and general fertiliser with the infill soil. Water regularly until established.
Fruit is produced on previous year’s shoots. Cut back all shoots by one-half after planting. Develop a framework of 6-8 branches. Each winter from year 3 shorten leading shoots by one-half and remove branches from the centre of the bush. Shorten side shoots from last year’s growth to 2 buds. Apply a general fertiliser in spring.
