    PRUNING PRUNING Presentation Transcript

    • Why do we prune trees ? Pruned trees less likely to split under a heavy crop, to improve fruit quality, and/or to reduce the crop load which will improve the potential size of individual fruits. Pruning
    • What crops require pruning ? •Deciduous trees •Citrus trees •Grape vines Pruning
    • Pruning what ? •Prune citrus to eliminate sprouts, remove weak, crossing or dead •Allow more light in the canopy •Remove all sprouts (water shoots) originating from the trunk. •Open skirting of the tree (orchard sanitation) •Shape tree to provide strong scaffold branches for crops Pruning
    • Cut types Pruning
    • Cut types Pruning
    • Design or structures: The rod and spur (cordon) system: Pruning
    • Farming Light Light provides the energy for photosynthesis in which carbon dioxide from the air and water from the soil are combined in the leaves to form the basic foods upon which trees live, grow, and bear fruit. In citrus, carbohydrates are stored in leaves, twigs, and branches. The maximum amount of stored food is reached in spring just before the onset of growth flush activity. The foliage of citrus trees therefore acts as an important food storage area, and heavy pruning causes the tree to produce vegetative growth at the expense of fruit production. Sunlight not only influences flowering and fruit set but also enhances fruit quality and color development. Pruning
