    Pruning Shears

    Flowers are harvested with sharp knives or electric pruning shear. On

    standard carnations two to three nodes and on spray carnations three to four nodes are left on the shoots for the next flowering. Flowers should be cut in

    the early morning when plants are turgid. Standard carnations are harvested as open flowers or in the bud stage. Spray carnations are harvested with two

    flowers open and the rest showing color. Flowers are handled carefully to avoid breakage and bruising. It is important to expose flowers to a 40° to 48°F

    environment as soon as possible to reduce plant temperature. Precooling the flowers maintains quality and increases longevity.

    Above all else, investment in a pair of high-quality pruning shears is mandatory. One manufacturer even has a special hand grip designed for left-handed

    people, swivel handles and a model with blade removal for maintenance. For miniature roses, there are smaller versions of these pruning shears which rely on

    a smaller, straight-edged blade surface. For removal of large woody canes at the bud union, a pruning saw will allow access for flush removal. Attempts to

    use pruning shears for these jobs usually result in damage to the bud union. It is best to approach cane removal with a proper saw designed specifically for

    the job. For cutting large-diameter canes a pair of lopping shears with 30- or 45-cm handles can facilitate the cutting without placing too much pressure on

    the hands. Again, attempts to cut large-diameter canes with pruning shears will require a lot of extra strength. Lopping shears with long handles solve the

    strength problem and make the cut clean and sharp. Invest in a small wire brush (about 5 cm wide by 75 cm deep) to help remove loose bark from the bud union.

    Such treatments can often encourage basal breaks and stimulate new growth since growth often finds it impossible to break through the heavy tree-like bark

    encountered on older bushes. Finally, save on profanities while pruning by buying a good strong pair of leather gauntlet gloves or hand gloves that are

    puncture-proof. There is nothing as irritating as a thorn under the nail to cause a string of words rarely heard in a rose garden!

    Harvesting is done manually when the capsules are dry at the ends of the branches. Pruning shears are used to cut branches and also remove inflorescence

    containing 15–20 capsular fruits. Once harvested, the fruit are carried in baskets to a land or a warehouse where, after drying, they will be processed in

    specific equipments or manually. The machines separate the capsules from the seeds and classify them for subsequent packing in polyethylene bags, where they

    remain preserved for more than five years in perfect condition without any plant protection treatment (Cruz et al., 2008).
