Cutting the top off a conifer, also known as topping, can have detrimental effects on the tree’s health and appearance. As a gardening and landscaping expert, I strongly advise against this practice, especially for large evergreen trees.
When you top a conifer, you remove the upper main stem of the tree. This opens up the tree to potential problems such as internal decay, disease, and damaging insects. Topping disrupts the natural growth pattern of the tree and weakens its structure. The exposed cuts are susceptible to rot and decay, which can spread to the rest of the tree if not properly treated.
Moreover, topping removes the most productive portion of the tree. The top of the tree is responsible for capturing sunlight and converting it into energy through photosynthesis. By removing this crucial part, you are essentially reducing the tree’s ability to produce food, leading to stunted growth and overall decline in health.
In my personal experience, I have seen the negative consequences of topping conifers. I once encountered a large evergreen tree that had been topped several years ago. The tree had developed extensive decay in the exposed cuts, which had spread down into the main trunk. The tree was weak and had lost its natural shape and beauty. It was a sad sight to see, and it could have been prevented if proper pruning techniques had been employed.
Instead of topping, there are alternative methods to control the size and growth of conifers. One option is selective pruning, where specific branches are pruned to maintain a desired shape or size. This method allows for the natural growth pattern of the tree to be maintained while still managing its size.
Another approach is to choose the right conifer species and cultivar for your specific landscape. Some conifers naturally have a more compact and slower growth habit, making them suitable for smaller spaces. By selecting the right tree from the beginning, you can avoid the need for drastic pruning measures.
Cutting the top off a conifer through topping is not justified. It can lead to internal decay, disease, and insect infestation, while also removing the most productive part of the tree. Instead, opt for selective pruning or choose appropriate conifer species to manage the size and growth of the tree. Let’s prioritize the health and beauty of our trees by avoiding harmful practices like topping.
