CALENDAR OF OPERATIONS.

DISBUDDING.—This operation does not appear to be sufficiently recognised

in its proper sense as distinguished from pruning and pinching. In

performing these latter operations we remove a portion of the growing

shoot, in the former case the young bud is removed as soon as it can be

rubbed off. These operations are therefore quite distinct, and their

distinction is of much importance. Most fruit cultivators are aware that

trees suffer materially by suddenly depriving them of a large portion of

foliage while in active growth, and expedients are resorted to in order

to render the operation less injurious. In spring when the buds burst,

attention should be directed to the quantity of young shoots desirable

either for fruit or uniformity of growth; these being secured all others

should immediately be _rubbed_ off. As growth proceeds luxuriant shoots

are _stopped_ or their points pinched off, removing more or less of the

shoot, according to the object to be attained. If the plant is very

luxuriant, more leaves may be removed and if _every_ shoot upon a tree is

operated on in this manner it amounts to a severe check on its growth. In

the case of young trees, or weakly ones, where a certain form is desired,

the young growing point should be bruised without removing any of the

elaborating foliage, securing density of habit without any perceptible

check of growth. Suppose a shoot that has grown 12 or 14 inches to be

pinched back one half of its length, the uppermost bud will burst again

and the others remain comparatively dormant; but allowing the same shoot

to have been checked in its longitudinal growth, by pinching or bruising

its extreme point, it will be found that all the lower buds will be

benefitted and several additional shoots produced. We have alluded to

this subject more particularly at present as we are aware of having

occasionally made use of the term _pinching_ when _disbudding_ would have

been the more appropriate expression.

STRAWBERRIES.—Preparations should now be in progress for securing plants

for early forcing next spring. Various methods are adopted to get strong

plants, such as filling small pots with rich soil and plunging them in

the strawberry patch, introducing a young plant on the pot, and removing

into larger ones when rooted. Others again prepare full sized pots at

once and place them in this manner, securing the young plant in both

cases with a small stone laid on the surface. When close attention is

paid in watering, these plans are good. An equally successful and less

troublesome method is to prepare a few square yards of ground in a

somewhat sheltered situation, manuring it well and digging deeply, and

filling it thickly with young plants. They should be partially shaded for

a few days, and duly watered. In the course of three or four weeks they

will lift with good balls of earth and are potted at once in fruiting

pots. Pistilo-staminate or hermaphrodite varieties are found to produce

better when forced early than pistillate sorts.

Root pruning of fruit trees is sometimes commendable, and the present is

the proper season for its more immediate beneficial effects. It is mostly

performed on young vigorous trees that show no disposition to fruit. By

cutting away some of the strongest roots at this time the supply of sap

will be lessened and the wood ripening process accelerated. No fruit

need be expected from badly ripened wood. In nine cases out of ten the

non-appearance of fruit on healthy trees arises from this cause. Mild

autumn weather induces growth to a late period and sudden frosts arrive

before the wood is sufficiently matured. This is more particularly

noticeable on soils inclined to be wet, and here again we perceive the

necessity of underground drains, in order to remove surplus water. It

is an exceedingly erroneous idea that drains are worse than useless in

localities where long droughts are of frequent occurrence. The truth is

that draining enhances humidity during hot weather, since it enables the

soil to exercise its absorbing properties to the fullest extent, there

being more air in the soil water is retained in its pores, constituting a

reservoir holding a lasting supply when other sources fail.

RENOVATING OLD TREES.—Most satisfactory results have been obtained from

old and apparently worn out trees by changing the soil about their

roots, or applying a top dressing of wood ashes, guano, salt and plaster

in equal quantities, allowing about one bushel of the mixture to each

tree. If nothing better is convenient, a heavy dressing of well made

barn manure forked in about the roots will have a decided effect. The

absorbing points of the roots extend a considerable distance from the

trunk, therefore, the principal part of the top dressing should embrace

a circumference at least equal to that of the branches. It might be

considered unnecessary to mention this _very_ apparent fact, were it not

usual to observe manure applied to the stem instead of the roots.

GRAPES UNDER GLASS will now be approaching maturity. Dryness both in

soil and atmosphere favors this process, still they must not be allowed

to suffer for want of moisture should the weather prove dry. The young

growth may be stopped more rigidly as the ripening process proceeds. This

will concentrate the sap and strengthen the buds for a future crop, if

pinched back too severely these buds may start into growth, which must be

guarded against.

OUT-DOOR GRAPES will require attention in thinning out lateral shoots

and stopping others especially those on bearing shoots. Thinning out the

berries is seldom practised on these, nor, indeed is it always necessary.

Occasionally, however, the berries are so thickly placed that room is not

afforded them to swell out and ripen properly. By thinning out a few of

the most central and smallest berries, the fruit will ripen earlier and

be much improved both in size and flavor.
