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.

Pretty tough
Color: Black & Lake Blue
I think the toy is great, but my dog was not excited about it. He prefers the original type which is larger. I think it could possibly be cracked open by a dog with a large mouth and is intent on getting the noise maker out. But it is pretty tough.

Definitely tough but not enough
Color: Black & Lake Blue, Color: Black & Lake Blue
I've been searching high and low for a durable and engaging toy for my 90lb american bulldog. She's destroyed countless toys and her number of toys just keep rising. This lasted for a few hours before she was able to chew off the rubber shell. But now shes still enjoying the hard plastic ball on the inside. Its also a perfect size of ball for her as she can fit it in her jaws comfortably without any worry of he swallowing it. Wish the outside shell was more durable though.

Large ball, still makes noise and hasn’t chewed it up yet.
Color: Black & Lake Blue
He loves playing with it and it actually doesn’t get swallowed up in his very large mouth. He can still bark talk with it in his mouth which is impressive due to its larger than a softball. It nice because I don’t feel like I’m shoving my hand in his mouth to get it out which baseball size or smaller things I do. He hasn’t chewed it up like he does other squeak toys and it makes lots of noise when tossed and bouncing. It’s hard and he insists on playing with it. we broke a pot when we accidentally hit the pot with the ball. He is always bringing me toys to throw down the hall as we watch tv. I’m like no not that one get a different one. I’m afraid I’ll break something with that one due to how heavy and large it is. That one is an outside toy, he still brings me this one daily and we’ve had it for several weeks now. Plus my cousin little boy just visited and he loved playing with it too. Its made out of material that’s easy to clean for the 17month old to play with in his play pen. It’s not so heavy you can’t throw it just heavier than the others I’m willing to toss down the hall.
