Often the bark of trees such as larch, oak, pine, spruce is used to create mulching material.
When you set out to collect the bark, you do not need to cut it from living trees. There are many resinous substances in it, and this greatly harms the plant. It is also not worth collecting bark from old stumps. Usually, it is already severely tormented by insects, and becomes practically unusable. The best material for collecting will be freshly sawn or recently felled by the wind trees (six months). From such trees, the bark begins to lag, but does not rot. And this is perfect!
For use, the bark is crushed to the desired size using a secateurs. After it is thermally processed. If you do not carry out this procedure, then you may have harmless and not very neighbors. When processing the bark, you need to boil or process 10-15 minutes. You can leave the bark in the oven for 15 minutes at a temperature of 70 degrees Celsius. Steam treatment is not recommended.
Which mulch is more suitable: coniferous or deciduous? Here the main role is played by the goal, as well as the availability of material for mulching. If you have a pine forest nearby, then, of course, you can use the bark of these trees. If the garden has a lot of heather, rhododendrons and conifers, then it is better to use the latter, since it contains a large amount of mushroom mycorrhiza. Oak bark lasts a little longer than coniferous - about two times. But it emits tannins, which negatively affect some types of plants. Therefore, before using it, you need to study whether it is suitable or not.
