If, however, Nature is too much tried, that is, if too much violence is done to her, she sulks and will exert herself no more. Up to this point, therefore, it is well to urge her. How can we know when we have reached it?
Only general rules can be laid down. Experience is the great desideratum on this and many other subjects connected with Tea.[34]
If the plant can always be kept in such a state that the foliage, without being very much so, is still less than Nature requires, I conceive the object will be attained.
The greatest violence is done to the plant when it is pruned, and reason would seem to argue that when this violence is repairing, that is, when the first shoots in the spring show themselves, and until new mouths (or leaves) in sufficient quantities exist, until then but little leaf should be picked.
Fortunately, moreover, while in the interests of the plant this is the best plan, it also is the mode by which the largest yield of leaf will be secured in the season. I go to show this.
The ordinary size of a good full-grown Tea plant, at the end of the season, is, say, 3½ or 4 feet high, and 5 feet diameter. It is pruned down, say, to a height of 2 feet, with a diameter of 3 feet. It is then little more than wooden stems and branches, and to anyone ignorant of the modus operandi in Tea gardens, it would appear as if a plantation so pruned has been ruined. The tree remains so during all its hybernating period, that is, during the time it is resting and the sap is down (this period is longer or shorter, as the climate is a warm or cold one, and it is always during the coldest season), but on the return of spring new shoots start out from the woody stems and branches in the following way:—At the axis or base of each leaf is a bud, the germ of future branches, these develop little by little, until a new shoot is formed of, say, five or six leaves, with a closed bud at top. Then if it be not picked the said bud at top hardens. At the axis or base of each of the said five or six leaves are other buds, and the next step is for one, two, or three of these to develop in the same way and form new shoots. The original shoot grows thicker and higher until it becomes a wooden branch or stem. The same process, in their turn, is repeated with the new shoots. A diagram (see next page) will make my meaning clear. We here have a shoot fully developed, of six leaves, counting the close leaf a at top as one, viz., the leaves a, b, c, d, e, f. The shoot has started and developed from what was originally a bud at K, at the axis or base of the leaf H. In the same way as formerly at K a bud existed, which has now formed the complete shoot or flush K a, so at the base of the leaves c, d, e, f, exist buds 1, 2, 3, 4, from which later new shoots would spring. These again would all have buds at the base of the leaves, destined to form further shoots, which again would be the parents of others, and so on to the end of the season, or until the tree is pruned.
It will readily be seen the increase is tremendous. It is only limited by the power of the soil to fling out new shoots, and the necessities of the plant, for, as I have explained, when as much foliage exists as the plant requires, but few new shoots are produced.
Now supposing the shoot in the diagram to be (with perhaps another not shown at L) the first on the branch I I in the spring (the said branch having been cut off or pruned at the upper I). It is then evident the said shoot is destined to be the parent and producer of all the very numerous branches and innumerable shoots into which the plant will extend in that direction. It is, in other words, the goose which will lay all the future eggs. If, eager to begin Tea making early, the planter nips it off, the extension on that part of the tree is thrown back many weeks. It may be taken off at 1, 2, or 3 (the back lines drawn show the proper way to pick leaf); the least damage will be done if it is taken off at 1, the most at 3.
The said shoot K a is the first effort of Nature to repair the violence done to the tree by pruning. It is the germ of many other branches and shoots, and it ought never to be taken. I have, I hope, made so much plain.
