Growing Cane Fruits: Blueberry, Boysenberry, and other Unusual Fruits
In addition to the Japanese wineberry, there are a number of unusual cane fruits which can be grown in exactly the same way as blackberries or loganberries. All of them must be trained up wires to keep them off the ground and all need heavy manuring.
Prepare the plot where the canes are to be planted by forking in well-rotted compost at 2 bucketfuls per sq. yd. And addingmanure with a 6 per cent potash content at 3 oz. per sq. yd.
Buy one- or two-year-old canes, plant them in October or November in rows with 8 ft. between the plants and 8 ft. between the rows. Spread the roots out and plant firmly. Then mulch the ground with sedge peat for 2 or 3 ft. round each cane. All canes should be cut down to within 1 ft. of the ground each February.
This is one of the heaviest-cropping cane fruits and is said to have come from blackberry, raspberry and loganberry stock. Its large fruits are round and dark reddish-brown in colour, are not too seedy and have very little core. The canes do not usually start growing vigorously until 18 months after planting. Once the roots are established, strong canes are produced which bear well. It is hardy and very resistant to drought. The fruit is ready to pick in July and August.
KING’S ACRE BERRY
This hybrid was produced by crossing a blackberry with a raspberry. The fruit comes away from the core like a raspberry and looks like a long blackberry. It has good flavour. The canes are sturdy and crop heavily. The fruit is usually ready to pick in mid-July or early August.
This is probably a cross between a blackberry and raspberry. The fruits, which are large, conical and dark-lilac coloured, are good for bottling and preserving. They are usually ready to pick in August.
This is a kind of loganberry which produces larger fruit and ripens later. Do not pick the berries until they are fully ripe, otherwise they will be too acid. They are not ready until August, when they are a reddish-purple colour.
UNUSUAL BUSH FRUITS YOUNGBERRY
These originated from Young’s Nursery, California, from a cross between the dewberry and the phenomenal berry. The plant is very thorny. The berries are black, large, juicy with few pips and are easy to pick as they grow away from the canes. May be planted as close as 7 ft.
This is a cross between a blackberry and the raspberry November Abundance. The fruits are ready to pick in August, when they are twice as large as blackberries and in fact look like large mulberries. The canes are reddish-purple and look very pretty in the winter.
This is said to be a cross between a gooseberry and a black currant. It grows as a strong, prickly bush like a gooseberry. The fruit is dark red, of gooseberry shape but of black currant size. Because of their prickles, the bushes are not easy to prune nor the berries easy to pick. Worcester-berries make a good impenetrable hedge if planted 3 ft. apart. When grown as bushes, plant them at least 6 ft. apart.
This shrub, a native of North America, requires an acidand a site where the roots can find water about 20 in. below the surface. Plant in rows 6 ft. apart with 4 ft. between the rows. Hoe between the rows regularly during the first year but in May of the second year apply peat all over the ground to a depth of l in.
Propagate by means of 6-in. cuttings of hard wood from the previous season’s growth. Insert these into the soil 4 in. deep. Do not prune until the third year, when some of the older wood may be cut out. The fruit is produced on the previous season’s growth. The berries are ripe during August and September. The best variety to choose is Rubel, because it is the only kind which sets its fruit satisfactorily without a pollinator.
