With regard to the nature of the soil, Lord Lymington says: "Strong clay produces the best oaks and the best silver fir. A deep loam is the most favourable soil for the growth of the Spanish chestnut and ash. The beech is the glorious weed of the chalk and down countries; the elm of the rich red sandstone valleys. Coniferous trees prefer land of a light sandy texture; ... but as many desire to plant conifers on other soils, I would mention that the following among others will grow on most soils, chalk included: the Abies excelsa, canadensis, magnifica, nobilis, and Pinsapo; the Pinus excelsa, insignis, and Laricio; the Cupressus Lawsoniana, erecta, viridis, and macrocarpa; the Salisburia adiantifolia, and the Wellingtonia. The most fast-growing in England of conifers is the Douglas fir.... It grows luxuriantly on the slopes of the hills, but will not stand exposure to the wind, and for that reason should always be planted in sheltered combes with other trees behind it.
"In moist and boggy land the spruce or the willow tribes succeed best."
"In high, poor, and very dry land, no tree thrives so well as the Scotch fir, the beech, and the sycamore."
Avoid the selfishness and false economy of planting an inferior class of fast-growing trees such as firs and larches and Lombardy poplars, on the ground that one would not live to get any pleasure out of woods of oaks and beech and chestnut. How frequently one sees tall, scraggy planes, or belts of naked, attenuated firs, where groups of oaks and elms and groves of chestnut might have stood with greater advantage.
Avoid the thoughtlessness and false economy of not thoroughly preparing the ground before planting. "Those that plant," says an old writer, "should make their ground fit for the trees before they set them, and not bury them in a hole like a dead dog; let them have good and fresh lodgings suitable to their quality, and good attendance also, to preserve them from their enemies till they are able to encounter them."
Avoid trees near a house; they tend to make it damp, and the garden which is near the house untidy. Writers upon planting have their own ideas as to the fitness of certain growths for a certain style of house. As regards the relation of trees to the house, if the building be of Gothic design with the piquant outline usual to the style, then trees of round shape form the best foil; if of Classic or Renascence design, then trees of vertical conic growth suit best. So, if the house be of stone, trees of dark foliage best meet the case; if of brick, trees of lighter foliage should prevail. As a backing to the horizontal line of a roof to an ordinary two-storey building, nothing looks better than the long stems of stone pines or Scotch firs; and pines are health-giving trees.
Never mark the outline of ground, nor the shape of groups of trees and shrubs with formal rows of bedding plants or other stiff edging, which is the almost universal practice of gardeners in the present day. This is a poor travesty of Bacon's garden, who only allows low things to grow naturally up to the edges.
From the artist's point of view, perhaps the most desirable quality to aim at in the distribution of garden space is that of breadth of effect—in other words, simplicity; and the larger the garden the more need does there seem for getting this quality. One may, in a manner, toy with a small garden. In the case of a large garden, where the owner in his greed for prettiness has carried things further than regulation-taste would allow, much may be done to subdue the assertiveness of a multiplicity of interesting objects by architectural adjuncts—broad terraces, well-defined lines, even a range of sentinel yews or clipt shrubs—things that are precise, grave, calm, and monotonous. Where such things are brought upon the scene, a certain spaciousness and amplitude of effect ensues as a matter of course.
One sees that the modern gardener, with his augmented list of specimen-plants of varied foliage, is far more apt to err in the direction of sensationalism than the gardener of old days who was exempt from many of our temptations. Add to this power of attaining sweetness and intricacy the artist's prone aspirations to work up to his lights and opportunities, and we have temptation which is seductiveness itself!
The garden at Highnam Court, dear to me for its signs and memories of my late accomplished friend, Mr T. Gambier Parry, is the perfectest modern garden I have ever seen. But here, if there be a fault, it is that Art has been allowed to blossom too profusely. The attention of the visitor is never allowed to drop, but is ever kept on the stretch. You are throughout too much led by the master's cunning hand. Every known bit of garden-artifice, every white lie of Art, every known variety of choice tree or shrub, or trick of garden-arrangement is set forth there. But somehow each thing strikes you as a little vainglorious—too sensible of its own importance. We go about in a sort of pre-Raphaelite frame of mind, where each seemly and beauteous feature has so much to say for itself that, in the delightfulness of the details, we are apt to forget that it is the first business of any work of Art to be a unit. There is nothing of single specimen, or group of intermingled variety, or adroit vista that we may miss and not be a loser; the only drawback is that we see what we are expected to see, what everyone else sees. Here is greenery of every hue; every metallic tint of silver, gold, copper, bronze is there; and old and new favourites take hands, and we feel that it is perfect; but the things blush in their conscious beauty—every prospect is best seen "there!" England has few such beautiful gardens as Highnam, and it has all the pathos of the touch of "a vanished hand," and ideals that have wider range now.
