Pruning Ornamental Shrubs
Pruning is the way to encourage your plants, shrubs to grow healthier, by removing deadwood and diseased, by cutting selective branches, buds and roots, this will help to encourage more shoots, buds and flowers and also good to cultivate for new specimen from a chosen plant.
There are also special techniques to pruning roses, fruit trees and grapevines, other practices for pruning herbaceous plants are used on perennial woody plants. When it comes to hedges, there are normally carried out by hedge trimmers.
Deadheading flowering plants is a way to encourage the plant to flower more over the summer and improves its appearance. This is done by removing drooping flower heads either by secateurs or if you are deadheading plants like French marigolds this can be done with your finger and thumb, before they set seed, enabling the plant to conserve its energy.
