Pest and Diseases of Apricots

By John Hopkins

For apricots there must be some shelter from cold winds. There must be protection from the spring frosts, and there must be sufficient depths to the soil. Some people say that the spring frosts not only kill the blossom but damage the young wood and so start the die- back.

The aphides which canse the leaves to curl and the young shoots to be twisted may be prevented by spraying with a tar-oil wash in December, or by soaking with liquid derris when they are first seen.

Blackberries, of course, grow on their own roots and are not budded or grafted on to stocks. Blackberries grow very well indeed on the compost system. It pays to apply straw a foot deep or more not only between the rows but among the plants and thus there is no hoeing or forking to do. Such straw should be applied at the end of the first year, once it is known that the canes are growing well.

Each early March a fish manure with a 6 per cent potash content should be applied at the rate of about 3 oz, to the sq. yard, or 6 cwt. per acre. This should be put on top of the straw and be allowed to trickle through or wash in. If it is thought the canes are not growing clay, however, I prefer to plant early in the spring. This results in the least amount of loss.

There is little doubt that it pays to protect the blossom when it is out with sacking or fish-netting. It is usual, also, to titillate the blossoms with a rabbit's tail on the end of a bamboo, or a long camel hair brush, the idea being to the pollen artificially. If you are lucky enough to get a heavy crop, thin the fruits to 6 inches apart when they are as big as acorns. The apricots should be at least 4 inches away from one another.

New Large Early is one of the special Rivers varieties. Large oval fruit. Orange-yellow and red. Hardy, fine flavour. Season end July-early Aug. Peach was widely grown years ago. Fruit oval, rich yellow and red, pungent flavour. Bush thinks it the best flavoured. Season end Aug.-early Sept. Royal Orange is sometimes labelled 'Royal'. Fruit oval, yellow spotted with purple. Ripens ten days earlier than Moorpark. Season early Aug. Shipley's Blenheim is the best for bottling and jam. Fruit oval, rich orange and crimson. Hardy and prolific. Season mid Aug.
