FIG. 121. APPLE BLOSSOM.
APPLE (Pyrus Malus). The Apple is one of the most useful, and probably most largely cultivated, of our hardy fruits. It is known as the Crab in its wild state, and is indigenous to Britain and to all the temperate and warmer parts of Europe. It is supposed that the progenitors of the varieties now grown were introduced to this country at various times from the Continent, and not obtained here as direct improvements on the native Crab. Those now cultivated are extremely numerous, and include good varieties that can be made to prolong the season all the year round. Apart from its great value as a fruit, the apple is a strikingly handsome tree when in flower (see Fig. 121). A fruiting branch is shown at Fig. 122.

Propagation. Seeds are sown extensively, chiefly for raising stocks to graft approved sorts on; also with a view to raising new varieties. The seeds do not retain their germinative properties very long, consequently they must be sown soon after being taken from the fruit. As grown in this country, they are generally sown in the autumn, transplanted the following year, and so on until they are of sufficient size for Grafting purposes. The standard of excellence being at present so high, improved forms raised from seed are comparatively scarce.
Grafting. This method of propagation is the one generally adopted for most purposes, the stocks being previously prepared for size or height of tree required. Cordon and other dwarf-trained trees should be worked near but not below the ground, while standards are best worked on stocks of the desired height. The practice of working standard trees low, and growing the scion to form the stem of the future tree, is not recommended, as many of the tenderer sorts will not grow straight or strong enough for the purpose. Whip-grafting is the most preferable mode adopted. The scions should be selected from healthy trees not later than January, and laid in singly in the ground until the stocks have slightly advanced in growth, which is generally about the middle of April. Several other methods of Grafting may be adopted with success, but the one above recommended is considered the best.
Budding. Apples may be successfully propagated by Budding, and this method is practised much more now than formerly. It has many advantages, as it requires to be performed at a season when there is not so much work in hand. It should be done in damp, dull weather, if possible, as the weather if dry soon destroys the buds. July and August is the proper time for the purpose. The stocks and woods from which the buds are taken should be as much as possible in the same condition.
Propagation by Cuttings, Layers, &c. This system may be made use of in the case of new varieties or where it is desired to increase any one variety with a limited number of scions, but the results are uncertain—at least in the case of cuttings; consequently, it is much better to resort to the safer method of Grafting.
