Shoots taken in early spring also shorten theperiod of storage.Cuttings must be taken from one year shoots and as far as possiblefrom the longer, straighter, clean, fully-ripened ones with the best-developedbuds, free from mechanical damage. Thin twigs are no use.Collected shoots must be stored before time for lining out, theobject being to prever.t the buds from swelling and loss of moisture. Ifthis is not done, the subsequent cuttings will lose much of their vitality.Shoots taken in early spring can be stored in cold buildings, cellars,ice hauses (humidity not to be lower than 80% cent and temperatur~not higher than plus 3 degrees C.)Shoots should be gradeci into 20, 30 and 4fl inch long bundles of 50' to10'0' each; avoid any mechanical damage doing this. The bundles of~hoo t s should have their butt ends on an earthen floor and are alsocovered with moss. .Cuttings which of llece~sity l1ave haJ to be taken in November aildDecember, can be stored during the winter time in trenches 2 ft. deep,in open elevated places. Lay the bundles of cuttings in a single rowalong the bottom of the trench and cover over with soil to a depthof 8" to 10"; cover the tops with straw.Severing the Cuttings from Shoots.Severance of the cutings from the shoots should be done on theday that the cuttings are lined out or not earlier than two dRys beforelining out, when they should be stored in wet moss during that period.In m'list conditions, the length of the cuttings should be from 8" to10", and in dry conditions 12" to 14". The shoots must be cut into cuttingsin such a way that the top end of the cutting lies not more thana half or three quarters of an i,nch above the last normally-developedsound bud. which, when the cutting is lined out, will remain above thesurface; this ensures that the new shoot will rise vertil!ally and not atthe side. The cut should be smooth ar..d slightly oblique.Grading of Cutting:;.This is done at the same time as the shoots are being divided intocuttings and it is desirable owing to the fact that the quality of thecuttings falls off in the direction ·,f their distribution from the butt to-the tip of the shoot.Grade I-Cuttings with an upper cross section diameter of f)/16" andover, taken from the butts to the middle portion of one-yearoldshoots, collected in the spring before the swelling of thebuds.
