This is PlantNest’s universal houseplant soil mix, a peat free compost designed for everyday indoor plants. It’s a simple, well-structured mix that drains well, stays airy around the roots, and works for most common houseplants without needing lots of adjustment.

It’s built around a lighter, more open structure than traditional houseplant composts. The blend of base substrate, pine bark and perlite creates a balance between moisture retention and airflow. It holds enough water to support steady growth, but doesn’t stay heavy or compacted around the roots. That makes it a good option if you’ve struggled with overwatering or dense soils in the past.

We’ve tested this mix across a range of plants at home and in the barn, and it’s been consistently easy to use. It drains well, holds its structure over time, and supports healthy growth without needing much tweaking. It’s one of those mixes you can use without overthinking it.

We’re stocking the 5L size, which is ideal for home use. It’s enough for a couple of repots, topping up existing plants, or keeping on hand through spring and summer.

What plants is this mix suitable for?
This is a good all-round houseplant soil mix for indoor plants, especially if you want something reliable and free draining. It works well for Monstera, Philodendron and Pothos, Ficus varieties, Dracaena, Spider plants, ZZ plants and many other foliage houseplants.

Because it’s a lighter, more open mix, it’s particularly useful for plants that don’t like sitting in wet soil. If anything, it leans slightly towards the drier side compared to heavier composts.

If you’re searching for the best soil for Monstera or a reliable houseplant soil in the UK, this works well as a base mix. You can use it as it is, or adapt it depending on your plants. Add a little extra compost if you want more moisture retention, or more perlite or grit if you want faster drainage.

When is the best time to repot houseplants?
Spring is usually the best time to repot indoor plants. As light levels increase, plants move into active growth and recover more quickly from repotting. Fresh houseplant soil at this point helps support stronger root development and more consistent growth.

That said, repotting can be done at any time if needed. Signs include roots growing out of the pot, soil drying very quickly, the plant becoming top heavy, or roots pushing the plant upwards.

How to use the mix
Use straight from the bag for most houseplants. After repotting, water thoroughly, then allow the top few centimetres of soil to dry before watering again.

Because this is a more free draining houseplant compost, you may find it dries slightly faster than heavier soils. That’s normal, and helps reduce the risk of overwatering.

Feeding plants after repotting
Fresh soil will provide some initial nutrients, but plants will still benefit from feeding once they’ve settled. We usually wait a couple of weeks after repotting, then begin feeding lightly.

Our Happy Houseplants Organic Tropical Plant Food works particularly well alongside peat free houseplant soils like this, supporting steady, balanced growth without pushing plants too hard.

A note on safety
As with most houseplant composts, this soil isn’t intended to be ingested and should be kept out of reach of pets and children.

Houseplant Soil FAQs

Is this a peat free houseplant soil?
Yes, this is a peat free houseplant soil mix, making it a more sustainable alternative to traditional peat-based composts.

Is this the best soil for indoor plants?
There isn’t one single “best” soil for every plant, but this is a reliable all-purpose houseplant soil mix that works well for most indoor plants, especially if you prefer a lighter, more free draining compost.

Do I need different soil for different houseplants?
Not always. Many indoor plants do well in a general houseplant soil like this. Some plants may benefit from small adjustments, but most growers find a good base mix like this covers the majority of their collection.

How long does houseplant soil last?
Stored sealed in a cool, dry place, it should remain usable for around two years. Nutrients will gradually reduce over time, but this can be topped up with regular feeding.

If you’re looking for a straightforward, peat free houseplant soil in the UK that’s easy to use and works across a wide range of indoor plants, this is a solid, dependable option.

Great size, design, and 100% metal grinding mechanism
Color: 1pcs-Sliver-304
***PLEASE NOTE: This review is only for the more expensive version here with the all metal grinding mechanism and not the cheaper version that looks the same but has a ceramic grinder that’s also available on this page — hope this helps avoid potential confusion. My advice is to splurge on the metal grinder version. ***UPDATE 3/18/26*** Well, after almost two years of fairly heavy daily use the first flaw has emerged so thought I’d share. Yesterday the silver wrapping on the grinder part came loose making it hard to turn the grinder as it was slipping. I did a quick fix by adding some super glue around the seam at the top of the grinder and that’s done the trick at least for now. I’m leaving my 5-star rating because I remain thrilled with its overall performance and frankly would’ve ordered another one if this fix didn’t work, but so far it appears to be holding. 🤞 So still very happy but just wanted to share in case anyone else experiences this. ***UPDATE 8/18/25*** So I’ve now had this for over a year, and under pretty heavy daily use I’m happy to report it still works as well as the day I bought it. Great product, and it’s a pleasure to use every day. ***UPDATE 10/3/2024*** So, after almost four months of pretty heavy daily use I just wanted to report back that this grinder continues to work perfectly and shows every sign of lasting for years to come. I especially like the glass jar so I can see when I’m running low on black peppercorns, and even though it’s got a small form factor it holds a lot so I don’t have to refill it frequently despite using it multiple times daily. I’m super happy with this product all around and recommend it highly!!! ================================ Been using this for a few days now and am very happy so far. I’ve used a traditional wood pepper mill my whole life, but now it’s just me so I wanted something smaller and with a glass body so I can easily see when I need to add more peppercorns. I also wanted an all metal grinding mechanism (that this version has for an few dollars more) instead of ceramic, which doesn’t seem to hold up as well, and I definitely wanted no plastic parts involved in the actual grinding either — don’t need any more microplastics in my diet thank you. This one seemed to check all the boxes, and so far it’s been great. Initially it was set to a more fine, powdery grind, but it was super easy to adjust to a more course grind that I prefer and it’s perfect. Overall it seems well built and is very easy to use, and as long as this holds up it’s a definite keeper. I’ll report back if any future mishaps, but as of now I’d recommend this very highly!

Most excellent spice grinder!
Color: 1pcs-Sliver-304
This spice grinder grinds my cumin and coriander seeds perfectly with very little effort and it’s attractive. I’m sure it will last longer than my plastic one that broke recently. Very happy with my purchase!

Good quality for an inexpensive salt/pepper grinder. Works fine and should last a reasonable time

Looks nice and seems to work well, but the black retaining ring randomly fell out.
Color: 1pcs-Sliver-304, Color: 1pcs-Sliver-304
The pepper grinder looks nice and initially functioned well as expected. However, as at least 9 other reviewers have noted experiencing, within 2 weeks of purchase and after very minimal usage, the black retaining ring around the grinder cone & adjustment knob just fell out when I was using the grinder, which was disappointing and indicative of poor design or construction for this part. After some research & experimentation, I was able to pop the ring back into place using needle-nose pliers (you just need something hard and narrow to push and flex the ring a bit, not necessarily pliers). I'm hoping that this is not a harbinger of other problems to come. Otherwise it's a nice grinder.
