Nurses for the Oak.
Here again, a good deal will depend upon the object of the planter, the nature of the soil, and the exact arrangements which are made at the time of planting; for it might be quite proper to plant a species of Tree in one place, while, owing to a difference in the staple or the condition of the soil, it would be just the reverse in another.
The remarks which I shall have to make on this subject have, in some degree, been anticipated by the observations which I have already made, respecting the Skellingthorpe Plantation, but a more particular reference to a few well-known kinds, may not be amiss.
I begin with the Larch, which, from its great value to Farmers and others, is fairly entitled to precedence.
The Larch is found, in greater or smaller proportions, in most places where Plantations are made; and it is entirely the planter’s fault, if he be not well acquainted with its character, as a nurse for Oak. I say this, because it has been so extensively tested, and its habits are so well known, that no one, having the slightest wish to become acquainted with it, can have failed for want of opportunity.
I have very often seen the Larch where it has proved an exceedingly bad nurse; where, in fact, instead of nursing the Oaks, it has destroyed them: but this has, of course, arisen from “mismanagement,” and might have been avoided. When good, stiff, healthy Oak Plants are put in with Larch only, or but with very few of any other sort, the Larch ought not, in the first place, to be put too near—the exact distance can only be determined relatively to that of the Oaks—secondly: an advantage should be given to the Oaks, if possible, at the start; either by assigning them a portion of the soil from the land intended for the Larch, or in some other way; after which, if the latter are constantly watched, they will approve themselves very suitable and valuable nurses; but if they are allowed, as they too generally are, to take the lead of the Oak, they will plentifully avail themselves of the licence, to the serious and, perhaps, irreparable injury of that plant.
For large Plantations, intended for profit, it may be questioned whether, in the first instance, any thing else than Oak and Larch should be planted, and the distance must be decided after due consideration is given to the quality and condition of the land.
If, however, a disposition is felt to plant other kinds, as nurses, there can be no objection, provided that their companionship is made fully to square with the well-being of the trees intended for timber.
But where it is intended to introduce nothing that shall not act as a good nurse for the Oak, exception must certainly be taken to the Alder, the Poplars, the Sycamore, the Horse Chesnut, the Birch, and the Scotch Fir, &c. Not one of these discovers any congeniality for the Oak, nor any fitness for the office of nursing it; and it does really appear to my mind, as most unaccountably strange, that trees of all sorts should, without forethought, or calculation—and most particularly, that no reference should be made to their suitability or adaptation for the circumstances in which they are to be placed—be planted at a greater cost than would have sufficed to procure an ample number of the right sort.
Upon a suitable soil, the Spruce Fir has always appeared to me, to be decidedly and incomparably the best nurse of the Oak. I have, for instance, often seen, on a clay soil, a Spruce Fir, and an Oak of twenty-five years growth, flourishing admirably, in close proximity with each other—even within a foot and a half. I do not think that this could be said of any other tree than the Spruce Fir; but besides this, there is almost always a very peculiar healthiness about the Oaks, where the Spruce has been planted and cherished as the principal nurse. There seems to be the best possible understanding between them—no struggling for pre-eminence—no blighting influence exercised by the one over the other. But the Spruce Fir is not found to flourish so well on some soils as on others: it will therefore, mostly, be advisable to unite with it, for a number of years, the Larch, which may be so placed as to be all weeded out during the course of thinning, which ought to commence in a few years after planting, and go on until there remains nothing but Oak in possession of the ground.
In concluding my remarks on Planting, I cannot help referring to the specimens of sowing and thick planting, which may be seen on the extensive estate of the Duke of Portland, at Welbeck, and in that neighbourhood. It has always been His Grace’s practice, either to sow Acorns, or to plant Oaks, in alternate beds, having Larch between. If the Oaks were planted, they were put in very thickly; and although their progress was necessarily slower than it would have been, if they had been allowed more room, it cannot be doubted that His Grace had a great advantage in the almost unlimited choice which it gave him, of trees of perfect form, for the ultimate crop of timber.
The system of thick planting has been fully carried out: having prepared the ground well, His Grace appears to have never lost sight, for an instant, of the young trees that he had undertaken to rear: there has been no mistaken practice—no niggardly economy—no ruinous neglect, rendering all his previous care abortive, and sacrificing his large outlay at the commencement. When the Plantations have required attention, they have evidently had it.
The admirer of fine timber will see, in the Duke’s Plantations and grounds, some of the most perfectly formed trees that can be conceived of, and that not on a small scale, but to an extent as comprehensive as that truly noble Duke’s genius, of whom it may probably be said that he unites, in his mind and person, as many of those qualities which constitute true Nobility, as any Gentleman of his day.
It is not in the power of my feeble pen to show the immense amount of good which has accrued to the immediate neighbourhood, from the employment of the poor in the locality, in carrying on, and in completing, those splendid improvements which His Grace has originated, and which have caused the literal desert to “blossom as the rose”: much less can I describe the area of the vast circle, within which the most beneficial effects have been felt, from the influence of the noble Duke’s example, while perfecting, as he has done, his various plans for the improvement of his fine estate.
In the Welbeck Plantations will be found, as I have said, a class of trees, most perfectly suited to the situations where they stand, and giving the surest promise of future superiority: but what, let me ask, would have been the quality of the Oaks, if the noble Duke had jumbled together an incongruous admixture of various sorts, as has been recommended by various writers of eminence, even in our own day? I am not disposed to enter into a controversy with any of those who have recorded their opinions in their writings, otherwise I might have plenty of work on my hands: it will be quite as much as ought to be expected from me, if I defend my own: but I would just quote a single paragraph from an interesting and useful, but, on some points, incorrect volume, published by “The Society for the diffusion of Useful Knowledge.” It is entitled “Useful and Ornamental Planting.” The passage to which I refer, will be found in the 43rd page, and runs thus:
“Simple Plantations consist of one or two species of trees only; mixed Plantations of many different species. The latter, on suitable soils, are the most profitable: they afford an earlier, more permanent, and a larger return for Capital than simple Plantations.”
In a book where there is so much to commend, where so many valuable practical directions are given, it cannot but excite regret, to meet with a paragraph so vague and unsatisfactory as the above; for I cannot but remark, that if any planter should adopt the suggestion which is thrown out, it will end in disappointment and loss. It will, in my judgment, generally be best for the planter to select such trees for nurses as are most congenial, and best adapted to the local market; and surely these will not be the Birch, the Beech, the Alder, or the Scotch Fir; none of which are ever found to answer the purpose of nursing the more valuable timber trees, or of securing a fair return for the investment of capital.
It is true that the opinion which I have quoted, is afterwards qualified by the remark, that certain “circumstances connected with the growth of the various species of forest trees, effectually control the planter in his modes of arrangement, &c.” but even with this limitation, the planter is liable to be misled, for he is not taught to set a higher value upon the Larch, which may in almost every locality be planted with a much better chance of profit, than the other kinds with which it is ranked, and which ought therefore, if profit be the object, for that reason alone, to be preferred.
In any thing else but planting, the mischief of such a mistake, as producing that which was worthless when produced, would, in a short time, have cured itself; but so little of science, or even of common calculation, have been brought to bear upon the practice of Arboriculture, that, notwithstanding the evidence which is every where to be met with, of serious “loss and disappointment,” for want of calculation, these matters go on very much as they “always have done.”
Finally, as to planting, it must, in every case, be perfectly clear to one who is competent to judge, that, whether the object be profit merely, or the embellishment of the landscape, the land ought to be as well prepared as circumstances will permit, and that such species of trees should be preferred, as are best adapted to the specific object of the planter.
The distance at which the plants shall be put in, is more a matter of opinion than some planters would be inclined to admit. For myself, I am disposed to think, that some advantages are lost to a Plantation, under certain combinations of soil and circumstances, when it is planted thickly, but I would not either rate the loss too highly, or express my opinion, with unseemly positiveness: my notion is, that the supposed advantages of planting thickly may generally be supplied by early, judicious pruning, and that the progress of the Plantation would be facilitated thereby: that, in fact, a Plantation of trees at a distance of three feet, being properly assorted, having had a good start, and suitable treatment in all respects afterwards, would reach any given point as to size, and quality, in less time than would another Plantation, upon the same soil, if the method of either sowing acorns, &c., or planting very thickly, were adopted. In saying this, I by no means wish to condemn the practice of thick planting; to do this, in the face of proofs of success, such as I have described as existing in this country, would be an absurdity of which I would not willingly be guilty; but at the same time, I would not hesitate to range myself among those who prefer, under ordinary circumstances, to plant at a moderate distance, and rely upon early pruning, for securing the object which the close planter has in view, viz., length of bole, or stem, and clearness of grain.
I come now to remark upon the
