Click below to listen to my Garden Bite radio show: Superstar (inorganic) mulch
I think it’s time for the mulch talk. We know it’s a good idea but what KIND of mulch should you get. Organic vs Inorganic. The first question to ask yourself is what do I want my mulch to do? Do I want it to just sit and look pretty or do I want it to work for the money I put into it? There are good reasons for both options. Today we’ll focus on inorganic mulch or Superstar mulch as I call it.
Rock Mulch, okay, I have a bias against this stuff. It’s a pain the b….ack. Side. If you’re using it as a weed suppressant than expect to have to use chemicals to kill the weeds that eventually come up through it because moving it is HARD work.
However, there are people who still want it, so if that’s you, then go ahead. But first, take a sample home. Most places will allow you to take a sample and see if it’s really the color you want. Also, I would limit where you put it.
This isn’t a bad place to use rock, however, you’ll still be cleaning this out from blown leaves and weeds will show up. LIFE wants to grow!
As you can see there are certainly plenty of choices.
Recycled Rubber Mulch is another inorganic choice. It’s an idea for the childrens playground or in an area you have no plans to plant. Rubber mulch doesn’t breathe. No weeds will come up but getting water, nutrients and air to the plants you want to thrive, will be a problem. There are some studies suggesting it gives off toxins and gets too hot for plants. There are 2 schools of thought on the subject and I think it’s one you have to decide for yourself.
Recycled rubber mulch
Here’s something I don’t recommend:
Rubber mulch tree ring
They claim that air, water and nutrients can get through, if that’s true, then so can weeds. And then you’ve got the weeds coming up through rubber. Tough to pull! Also, rocks and rubber heat up. That’s not a good thing for most plants, they don’t need the extra hot soil.
Here’s some information from Nature’s Way Resources. Of course they do not recommend rubber mulch but you might want the information they offer.
