Soil Mix, Plant Food, and Vermiculite

A Planty Garden isn't dug directly into your backyard dirt. We use garden boxes or grow bags filled with a special soil: MM-Mix. 

This mix can be bought in individual bags, but also on pallets. To keep the nutrients in the mix up to snuff, it needs some extra plant food once in a while. 

Why do you need a special soil mix?

We work with planters that are about 20 cm deep and we cram them full to the brim with vegetables.  If you would do that in ordinary potting soil or straight in your backyard, you wouldn't get much out of it. In order to grow so intensively, you need a soil mix that gives your plants everything they need. 

Our MM-Mix is the only soil mix especially made for this intense growing with this system. It's full of natural nutrients, is nice and airy, and it retains moisture: exactly what plants like.

Really, soil mix choice will make or break your garden. With our MM-Mix you're guaranteed success. On top of that, you can leave the mix in your garden indefinitely. And it's really nice to work with. 

So, what exactly is the MM-Mix?

MM-mix is a loamy soil mix with lots of natural nutrients. It ensures your plants get a perfectly balanced diet. 

MM-mix It includes a mixture of three key ingredients: vermiculite, fiber and nutrient-rich compost. 

All vegetables thrive on the MM-mix: lettuce heads grow just as well as beets and beans. Herbs, flowers, potatoes, strawberries, even your houseplants love it :-).

The bottom line is: You never have to wonder if your soil is compatible with your pickier vegetables. With the MM-Mix, all plants thrive. 

Works great and nice to work with

Whatever you grow in your MM-mix, grows well. No fertilizing. That's it. 

It's also nice to work with: Go ahead, sift it through your fingers :-).

It retains water well without ever getting too wet. And it only provides the nutrition your plants need when they need it.

You can leave this mix in your containers for years and never have to replace it. Can't say the same about potting soil. 

Pallets of MM-Mix to your door

For a 120x120 cm garden box, you'll need seven 40L bags of MM-Mix.  

If you need a lot of bags or if you order together with a friend, a full pallet is cheaper than individual bags. And a pallet means free delivery for you.

If you have bags left over, you can become a temporary reseller if you like :-). Or give them all to that friend for their birthday.


In an Planty Garden, you don't use fertilizers. But even in this mix, once in a while, you will need to supplement the nutrients once your plants have used them up. We've made a special plant food just for this purpose: 

It is: 
  • 100% organic and environmentally friendly 
  • Compatible with all plants
  • Works for a long time - up to 5 months
  • Super easy to use
This plant food keeps your plants strong and healthy and gets you a huge harvest.

How and when to use plant food?

Vegetables that take longer to grow will stay in their square patch for a while. The longer they're there, the more nutrients they consume. I'm talking about plants like tomatoes and zucchinis. For these guys, the mix will need a plant food boost.

And, at the start of a new season, after your mix has been left alone for a months, you'll refresh your garden boxes with a healthy dose of nutrients.

MM-Plantfood comes in boxes of 1kg. There's a handy cardboard scoop inside. And the Planty Gardening app will tell you when and how much to add. It's no sweat :-).
