A raised bed around a tree takes oxygen from the roots
Can you build a raised bed around a tree?
The classic raised bed is rectangular and rather elongated. For some, this form is much too boring, so he is looking for more exciting alternatives. And if the garden is not very big, could you also build a raised bed around a tree? Why this is not a good idea and what you need to pay attention to when implementing this plan is explained in the following article.
Does the raised bed around the tree harm this?
Basically it is not a good idea to set up a raised bed around a tree. This will remove oxygen from the tree roots by artificially compacting the soil. In addition, you deprive him of its growth and propagation opportunities. However, under certain conditions, you can still put your plan into action.
Do not plant the raised bed directly on the trunk
First of all, the raised bed should not be set up directly on or in front of the trunk. By "burying" the trunk, you create a perfect breeding ground for decay fungi - after all, the filling of the raised bed is always moist and the air circulation between the bed and the trunk was cut off by the immediate spatial proximity of the bed. In addition, the tree also "breathes" over the stem, which is why the supply of oxygen subsequently suffers. With a raised bed around the tree you should therefore keep a sufficient distance between the bed and the tree trunk - the absolute minimum is 30 centimeters.
Do not completely adjust the root area
Also, the root area you better not completely adjusted with a raised bed. Here it is important, especially the fiber roots - which are the only able to absorb water and nutrients - to leave enough space. The fiber roots are always at the outer edge of the root disc and grow incessantly. You can use the treetop to determine where they are. It would be good not to completely seal the root area - however, a narrow raised bed is likely to be fine for the tree in most cases.
What are the options for a raised bed around a tree?
Naturally can be built from straight wooden boards no round raised beds. However, you do not have to, because a polygonal bed nestles just as well around the tree. Also, a border of wicker or lightweight plastic are well suited. On the other hand, you should do without a stone raised bed - this is too heavy for the sensitive root area of the tree.
Tips
Instead of building the raised bed around the tree, you can dig it out and put it in the bed if it's not old and over-established.
