Preen before Or After Mulch

When it comes to mulch, there are a lot of different schools of thought out there. Some people say that you should preen before you mulch, while others say that you should mulch before you preen. So, which is the right way to go?

The answer may surprise you: neither! It turns out that the best time to preen your garden is actually after you’ve applied your mulch. Here’s why:

1. Preening Before Mulching Can disturb The Ground If you try to preen your garden bed before applying mulch, you run the risk of disturbing the ground and disrupting any existing plant roots. This can cause serious damage to your plants, and it will make it harder for them to recover once they’re covered in mulch.

2. Preening After Mulching Is More Effective Preening after mulching is much more effective because the mulch will help hold the weeds in place while you’re working on removing them. This means that you won’t have to worry about re-seeding or replanting anything that gets disturbed during the preening process.

3. Preening After Mulching Saves Time Preening after mulching also saves you a lot of time in the long run because you won’t have to remove all of the weed debris from your garden bed once you’re done. The mulch will do most of the work for you!
