Strong growing varieties will stand more than weak ones, and no liquid manure should be given to newly planted trees. A dressing of Basic Slag in the autumn is recommended.
Pests.[14]—These are many, and the remedies are few and simple. Caterpillars, large and small, must be hunted for daily and killed with finger and thumb from April to July, however unpleasant the process may be, or the most promising buds will be spoiled. For destroying Aphis, which are very troublesome some years, a solution made by boiling Quassia chips in water, and adding soft soap when cooling, is often used; though "finger and thumb" drawn gently up the stem when the insect is first seen, puts an end to those on the shoot; and finger and thumb is even recommended for destroying Mildew on its first appearance, though this cannot be done when there is a bad attack.
Nothing in my experience equals Flowers of Sulphur for Mildew, when distributed by an "Ideal" powder bellows. This should be done quite early in the morning, when there is a promise of a hot, sunny day. If the wind is not too strong, the Sulphur will float through the plants like a cloud of smoke, searching into every part. This should be repeated once a week, and even before there is a sign of Mildew on the leaves, prevention being better than cure. But I know no remedy that will quite destroy it.
Exhibiting.—If the grower wishes to exhibit his flowers, he should follow the instructions here given; and I would also advise the reading of the late Rev. A. Foster Melliar's book on exhibiting, and the Rev. J. H. Pemberton's—both most excellent books—which enter more fully into particulars than space allows me to do.
The number of shoots having been reduced,[15] it will soon be time to gradually take away all the buds, except the centre bud and one other. This also must be taken away, as soon as the centre bud looks healthy and free from damage. Very strong growers, like Florence Pemberton, and those varieties having a great number of petals, will do better if the buds are not much thinned, or they will be coarse.
The N. R. S. definition of a good rose is: "The highest type of bloom is one which has form, size, brightness, substance, and good foliage, and which is at the time of judging in the most perfect phase of its possible beauty."
It will be necessary in the case of Hybrid Perpetuals to select the bud, which should be about three-quarters open, two days before the show (four or even five days for Teas), and to tie up, not tightly, the centre of the flower with Berlin wool, leaving the outer petals free, taking care that it is not wet with rain, or even dew. Bend the shoot down, if possible, and cover with a shade; some clean litter spread under dwarfs on the ground will keep the flower from being splashed by heavy rains. Teas are improved if covered with a cone of butter paper, as well as the shade; and some may be cut two days before the show, and if put in a dry, dark cellar, will remain in good condition. Maréchal Niel will improve in colour by being kept in the dark. The best time for cutting H. Ps. is from four to seven o'clock the evening before the show; they will lose a little in colour, but will stand longer than if cut before six o'clock on the morning of the show. Use garden scissors in preference to a knife. When getting the blooms, cut the stem five or six inches long, and remove the lower leaves, which only fill up the tube and do no good to the flower, and do not add to its appearance in the box. A receptacle with water should be taken round when cutting, and the flowers put in immediately and never allowed to become dry (the water must not be cold). The name should be attached at once.
The regulation size of the N. R. S. for rose boxes is "4 inches high in front and 18 inches wide, and of the following lengths (all outside measurements). For 24 blooms, 3 ft. 6 ins. long; for 18 blooms, 2 ft. 9 ins. long; for 12 blooms, 2 ft. long; for 9 blooms, 1 ft. 6 ins. long; for 6 blooms, 1 ft. long; for 8 trebles, 3 ft. 6 ins. long; for 6 trebles, 2 ft. 9 ins. long; for 4 trebles, 2 ft. long." The lid should have a depth of 9 inches to allow room for the blooms. Boxes are supplied at a moderate price by John Pinches, 3 Crown Buildings, Crown Street, Camberwell, who also supplies tubes, wire holders, and shades; they can also be obtained from horticultural firms. The tray of the box should be covered with moss. When the roses are all arranged for the night, give a little air by putting a prop under the lid, and leave the box in a cool place. When the boxes are placed on the show tables, lift the lids sufficiently high to get at the flowers. Each tube should be lifted and the rose raised, taking care that the stem is in the water. All damaged outer petals must be removed, and the flower if full with substance in it, may have the wool removed. Assist the opening of the blooms with a camel's hair brush. A gentle puff with the mouth at the centre will loosen tightly packed petals. Care must be taken when "dressing" a bloom, not to alter its character; for this, according to N. R. S., "shall count as a bad bloom." The ties must not be removed from the thin ones (those with few petals) until the last minute, when it is time to remove the lids. It will be necessary to take a few extra blooms in different stages of growth, to replace any in the box that have expanded; for a rose showing an eye gains no point. Care must be taken that there are no duplicates, but all distinct according to "schedule." Once exhibit at an important show, and many lessons will be learnt which can only be learnt there and then.
