HEDGE.
The question of fencing in this country, so much of which is prairie, and in other parts of which there is such a wanton waste of timber, gives great importance to successful hedging. The same plants are not equally good for hedge in all parts of the country. There are but few plants suitable for hedges in our climate.
The Osage Orange—is the best, in all latitudes where it will flourish. It has no diseases or enemies by which it will be destroyed, except too cold winters. Of Southern origin, yet it flourishes in many places at the North. In cold localities, where there is but little snow, it suffers much until three or four years old. It is being extensively introduced into central and northern Illinois, where unusually cold winters destroy vast quantities of young plants, and kill the tops of much old hedge. It is still insisted that it will succeed; but we consider it too uncertain, and consequently too expensive, for general fencing in such climates. The roots and lower parts of the plants may be preserved, however, by setting them out for a hedge on level ground, instead of ridges as usual, and plowing a furrow three feet from each side of the row, to drain off surplus water. Mulch thoroughly in the fall, and thus protect from frost until they have been set in the hedge for three years, and they may succeed and make a good live fence. To raise the plants, soak the seeds thoroughly, and, at the usual time of corn-planting, plant in straight rows, and keep clean of weeds. Set out in hedge the following spring. The soil of the hedge-row should be deep, mellow, and moderately, not excessively rich. Too rich soil makes a larger growth, of spongy and more tender wood. Plants should have a portion of the tap-root cut off, and be planted a foot apart in the row.
The Hawthorn—will never be extensively cultivated for live fence in this country, being subject to borers, as destructive as in fruit-trees.
The Virginia Thorn—is equally uncertain.
The Buck Thorn—after fifteen years' trial, in New England, bids fair to answer every purpose for American live fence: it is easily propagated, of rapid growth, very hardy, thickens up well at the bottom, and is exempt from the depredations of insects. It may yet prove the great American hedge-shrub.
The Newcastle Thorn—cultivated in New England, is much more beautiful, and promises to rival the buck thorn, but has not been sufficiently tested to settle its claims. Much is anticipated from it.
There are plants well adapted to hedge at the South, which are too tender for the North. In White's Gardening for the South, we have the following given as hedge-shrubs, adapted to that region: Osage Orange, Pyracanth, Cherokee, and single White Macartney roses. The Macartney, being an evergreen thorn, and said to make as close a hedge as the Osage Orange and much more beautiful, is quite a favorite at the South. They usually train the rose-shrubs for hedge on some kind of paling or wire fence. They render some of them impenetrable even by rabbits or sparrows; this is done by layers, and trimming twice a year, commencing after the first three months' growth. Pruning is the most important matter in the whole business of hedging. A hedge set out ever so well, and composed of the best variety of plants, if left in the weeds, without proper care in trimming, will be nearly useless. A well-trimmed hedge around a fruit-orchard will keep out all fruit-thieves. The great difficulty is the unwillingness of cultivators to cut off, so short and so frequently, the fine growth.
Shear off the first year's growth (a) within three inches of the ground (b). Cut the vigorous shoots that will rise from this shearing, four inches higher, about the middle of July, and similar and successive cuttings, each a little longer, in the two following years; these will bring the hedge to a proper height. The form of trimming shown in end view of properly-trimmed hedge, protects the bottom from shade by too much foliage on the top: the effects of that shade are seen in neglected hedge in the cut.
