An important problem was discovered during pruning. The pruner had no concept of controlling the amount of pruning in his brain, and there was a problem that the amount of annual pruning exceeded the annual growth rate. This is a very important issue, not only for garden pruners, but also for garden management decision makers to give precise pruning instructions and the healthy growth of garden plants. In the pruning at the end of winter and early spring, when we saw that individual plots had an inaccurate control of the amount of pruning, which had an irreparable impact on the health and growth rate of the tree, we realized that this issue must be paid enough attention. In response to this phenomenon, Lvxin Gardens analyzes the issue of pruning volume in detail from the following aspects, hoping that it can be a reference for garden decision-making and operators.

The reason why the annual pruning volume exceeds the annual growth volume In garden management, in some special circumstances, the annual pruning volume may exceed the annual growth volume, but it is wrong to do this pruning more often. The first reason is the lack of pruning knowledge and gardening. Common sense of plant growth, the second is the lack of sense of responsibility, arbitrary cutting, regardless of the consequences.

Annual pruning should not exceed annual growth. Garden plants with sufficient growth space and no special needs such as crown expansion or renewal should be under normal pruning management every year. Generally speaking, the amount of pruning should not exceed 2% of the growth. /3. Excessive pruning, especially heavy pruning with annual pruning exceeding annual growth, will seriously weaken the tree vigor, inhibit normal flowering and fruiting, resulting in scarce flowers and fruits and premature senescence.

The annual pruning amount can exceed the annual growth amount. In some special circumstances, the annual pruning amount can exceed the annual growth amount. The first is the abnormal pruning management of garden plants. Due to the perennial non-pruning or improper pruning, some sprouting branches and long branches that should have been removed are not removed in time, which seriously affects the growth of the garden plants or normal flowering and fruiting; the second is that they are young. Garden plants that need styling at age. These garden plants have long restocking branches due to the needs of early crown expansion and nutrient accumulation. When the required trunk diameter and main branch reach a certain thickness, the necessary fixed branch setting and retracting pruning are required. ; The third is the garden plants that need to rejuvenate in the debilitating period. Due to the needs of delaying senescence and promoting renewal, these garden plants often need to remove old and weak branches, diseased branches, often change their heads or retract and renew; fourth, some have special Garden plants with styling requirements or height requirements, some scenic spots have specific requirements for plant height or crown due to styling or embellishment needs, in order to meet the requirements, they have to be re-cut.

The consequences of the annual pruning amount exceeding the annual growth amount. The annual pruning amount exceeding the annual growth amount will cause premature aging or premature death of plants. Due to pruning, there are many and large wounds, which make the tree weak and difficult to rejuvenate; reduce the crown width, build too much, and cut too many leaves, resulting in reduced leaf photosynthesis, limited nutrient accumulation, insufficient nutrition, and natural growth inhibition. Poor growth will reduce the ability to resist adverse environmental factors, and cause high incidence of pests and diseases, which is difficult to control.

How to control the annual pruning amount is summarized according to the author's many years of pruning management experience: Generally speaking, the pruning amount of fast-growing garden plants can be appropriately loose, generally not exceeding 4/5; the pruning amount of slow-growing garden plants generally does not exceed 1/2; The amount of pruning of growing garden plants can be controlled at 1/2 to 4/5. Some garden plants with special styling requirements are restricted by location or space, or bonsai styling is another matter; garden management should not be re-cut every year, it should be three light and one heavy (ie: three young cuts, one year cuts, alternate), or Four lightness and one heavyness, combining lightness and heavyness, give plants a certain amount of time to recuperate.

Garden pruning is a double-edged sword. Proper use will benefit plants, promote stronger plants, better plant shapes, suppress pests and diseases, and have more obvious landscape effects; improper use will not only backfire, but will also destroy years of maintenance and management results. , Resulting in tree-shaped sickness and weak growth. Small problems are related to the big landscape and big benefits, and the pruning staff must pay attention to it.
