Gardenline Potting Mix

As an avid gardener, I purchase a lot of gardening products from Aldi. My garden supplies from the discount grocer include raised garden beds, raised planters, stacking planters, a walk-in greenhouse, a winter greenhouse, an indoor smart garden, and simple accessories such as gardening gloves, solar lights, and seed packets.

If you do any kind of container gardening, you’ll need a good supply of potting soil. I’m no stranger to purchasing bags of potting mix from my local nursery, but I also pick up bags of potting mix from Aldi when it’s in stock. You might wonder if Aldi potting mix is any good coming from a discount grocery store, but I’ve found that it works well for me.

Keep in mind that potting soil is not the same as garden soil, so what you need depends on how you’re gardening. Aldi sells both types of soil at different times during the spring, and you’ll want to make sure you pick out what you need. Potting soil is intended for use in pots, planters, or other containers. It is usually a mix of peat moss, ground pine bark, and perlite or vermiculite, plus limestone to balance the pH. Potting soil also typically includes a wetting agent to keep it from drying out, and it contains some plant food. Garden soil, on the other hand, contains topsoil or sand mixed with bulky organic matter. Garden soil with its coarser texture helps to loosen heavy clay soil and improve the soil overall.

Gardenline Potting Mix

Gardenline Potting Mix cost $4.99 for a one cubic foot bag (28.3 L) at the time of publication. That’s a better deal than Miracle-Gro Potting Mix at my local Walmart, where one cubic foot cost around $7 at the time of publication.

This is an Aldi Find, which means it’s only in stores for a short time. Aldi does not offer online ordering for its specials if they aren’t in stock at your local store.

Gardenline Potting Mix

I’ve used Aldi potting mix for years and have had no issues with it aside from the possibility that the plastic bags the mix is sold in may not be as sturdy as some name brands, but I select my bags carefully at the store and generally don’t have major problems with spillage.

Are there higher quality mixes out there? Probably. Could you get a generic brand at another retailer for a similar price? Possibly, but in my experience, Aldi products are usually better than other store brands. The mix has a good texture without large chunks, and it seems to retain moisture well. I’ve grown some excellent tomatoes, bell peppers, herbs, and flowers over the years using Gardenline Potting Mix, so I’ll continue to buy it when I see it at Aldi.

You can also find plenty of opinions about Aldi potting soil on reddit, with many people saying the Aldi mix is just fine, especially if you were previously purchasing other options such as basic Walmart mixes.

The Verdict:

Gardenline Potting Mix is made in the U.S. and is packaged by Oldcastle Lawn and Garden Inc., a company whose products are commonly found in major home improvement centers and retailers. The contents of the mix vary by region but include standard ingredients such pine bark, peat moss, perlite, a pH adjuster, an agent to help the mix retain moisture, and fertilizer. The texture is fine, without lots of large chunks, and this mix is great for growing seedlings in containers. We’ve used Aldi potting mix for years in our own gardening projects and have always gotten good results.

  1. Is the Gardenline potting soil safe for growing vegetables? Unlike the garden soil, there is no mention of vegetables on the bag and no mention of heavy metal guidelines. I have a container garden every year and bought 3 bags of the potting soil, but now I am feeling very uncomfortable about using it for edibles. I can’t find info anywhere about this and even called Oldcastle.

  2. I saw this potting mix at Aldi again today, while supplies last!

  3. Os this product slightly acidic?

  4. How come the stuff you have works, but the stuff I bought is a dud?
