  1. Techniques of Pruning Unit 33

  2. Objectives • To select proper pruning techniques for specific plants and demonstrate their use in the landscape • List 5 reasons for pruning • Describe 4 types of pruning • Demonstrate pruning a stem at the proper angle • Explain how the correct time to prune is determined

  3. Why are Plants Pruned • To remove dead, diseased, insect-infested, or broken branches • Keeps the plant healthy • To change the size or proportion of the plant • To keep them from becoming overgrown • Also helps to consider the mature height and growth rate before placing the plant • To develop a special form or shape • Topiary – practice used in formal gardens – plant material is trimmed into shapes (Edward Scissorhands) • Palier – method of training plant materials to grow flat against a trellis or wall

  4. To remove wilted or dead flowers and seed pods • To rejuvenate a declining shrub • After pruning a plant usually produces better quality flowers and develops a better form

  5. Equipment for Pruning • Tools must be kept clean and sharp to give a good clean cut • Lab Exercise 7-15; 7-16

  6. Types of Pruning • Thinning – removing certain branches from a plant to open up the plant • Allows more light to reach the inner branches • Heading back – removal of the end section of the plant branches at the same height • Causes new shoots to develop to make the plant thicker • Renewal Pruning – old branches that are large and unproductive are removed • Results in development of new branches and better flowering • Root Pruning – involves cutting off all the lateral roots of the plant in a circle around the stem • Root prune 1 season prior to transplanting

  7. How and When to Prune • Cut the plant stem at a 90 degree angle • When to prune depends on when the plant flowers or bears fruit • Flowers in spring = summer pruning • Shrubs pruned after they flower • Flower in summer or fall = pruned before growth begins in the spring

  8. Objectives • To select proper pruning techniques for specific plants and demonstrate their use in the landscape • List 5 reasons for pruning • Describe 4 types of pruning • Demonstrate pruning a stem at the proper angle • Explain how the correct time to prune is determined
