In general hydrangea plants do not require annual trimming, but to occasionally prune hydrangea can improve plant performance in many ways. Hydrangea pruning can increase crop yield and the quality of the flowers. Hortensia trimming is also a way of shaping the plant, controlling and directing growth, and it helps with diseased, damaged, and unwanted tissue. Cutting back hydrangeas can also produce bigger flowers. When you prune hydrangeas you are also removing deadwood and dead blooms, and this can improve plant health. Other methods of pruning are used for nursery specimens and for transplanting.
Pruning Differs by Type of Hydrangea
Depending on what type of hydrangeas you are growing in your garden, how and when to prune a hydrangea plant will differ. Mophead hydrangeas do not need to be pruned back unless the plants are very old. Removing dead stems and dying blooms can be done at any time on all types of hydrangeas and this is good for the health of the plant. It is best to cut back and trim hydrangeas after the flowers begin to fade in late summer. Pruning hydrangeas also differs if the plants you grow bloom on new wood or bloom on old wood.
Pruning hydrangeas removes deadwood and old blooms and helps produce pretty shapes, beautiful new and large flowering blooms.
Reasons to Prune Hydrangea?
Pruning is a horticultural method, which involves the selective removal of some of the parts of a plant, such as branches, buds, roots, or flower blooms. Specialized pruning can be applied to hydrangea plants for different reasons. Gardeners use a number of garden tools such as pruning shears to prune a plant. Pruning hydrangeas involves removing a portion of growing stem down to a set of desirable buds or side-branching stems. Pruning stimulates growth of flowers and branches, and encourages growth of the stems in a desirable direction. Cutting back or thinning involves the removal of an entire shoot, limb, or branch at its point of origin. Thinning is done to revitalize the hydrangea plant by removing over-mature, weak, problematic, and excessive growths. Trimming the plant also encourages the formation of new growth that will more readily bear flowers. The pruning regime in flower farms is deliberately planned and as the flower productivity of each hydrangea plant is an important factor.
