Premium General Purpose & Seedling Potting Mix | 5L

The one bag every grower should have.

Our Premium General Purpose & Seed Potting Mix is the most versatile mix we make.

Use it as an everyday potting mix for many common houseplants, herbs and vegetables, as a fine-textured mix for starting seeds and growing seedlings, or as a base to customize our specialty mixes to suit your plants and your growing style.

Whether you’re potting up a new plant, sowing seeds or creating your own recipe, this mix is ready to use straight from the bag.


Why we made this mix

Not every plant needs a highly specialized soil.

Sometimes you just need a dependable potting mix that holds moisture, drains well and gives roots the air they need to thrive.

We also wanted a mix that gives growers more flexibility.

Use it on its own, or blend it with our specialty mixes to fine-tune the texture for your plants and growing conditions.


One mix. Multiple uses.

One of the things we love most about this mix is how versatile it is.

Use it on its own for many common houseplants, herbs, vegetables and container plants.

Start seeds and grow seedlings. Its fine texture makes it ideal for delicate roots and young plants.

Create your own custom soil blends. Use it as a base to adjust the texture of our specialty mixes without having to buy multiple individual ingredients.

Fine Tropical Mix

Blend with our Premium Fine Tropical Mix if you’d like a finer, more economical blend while still maintaining excellent drainage and aeration.

Chunky Aroid Mix

Prefer a slightly finer mix? Blend it with our Premium Chunky Aroid Mix to reduce the chunkiness while still maintaining excellent airflow.

Succulent Mix

Combine it with our Premium Succulent Mix to create a gritty, fast-draining blend that’s still significantly grittier than many standard garden centre succulent soils.

Carnivorous Mix

It can also be blended with our Premium Carnivorous Mix, but there are a few things to keep in mind.

Our General Purpose & Seed Mix contains no added fertilizer or nutrient-rich amendments, making it suitable for growers who want to adjust the texture or stretch their Carnivorous Mix.

However, this blend is approximately a 50/50 mix of peat moss and coco coir. While coco coir is an excellent growing medium, it can naturally contain more dissolved minerals than peat depending on how it has been processed and rinsed.

If you’re growing mineral-sensitive carnivorous plants such as Venus Flytraps, Sundews or Sarracenia, we recommend measuring the TDS (Total Dissolved Solids) of your finished mix and using the appropriate blend for the species you’re growing. As always, use distilled, reverse osmosis or clean rainwater where appropriate.


Potting soil isn’t the same as soil outside.

Outside, worms, insects, roots and the weather are constantly loosening and aerating the soil.

Inside a pot, none of that happens.

Over time, potting soil can settle, reducing airflow around the roots and making watering more difficult.

That’s why good potting soil isn’t just dirt.

It’s a carefully balanced growing medium designed to create the right balance of moisture retention, drainage and airflow for healthy root growth.

Healthy roots grow healthier plants.

Complete Ingredient List

  • Peat Moss
  • Coco Coir
  • Perlite
  • Vermiculite
  • Sand

Every bag is hand mixed individually.

We don’t make giant batches and divide them into bags.

Every Plant King bag is hand mixed individually using the same recipe before it’s packaged.

It takes longer, but it helps keep every bag consistent from the first scoop to the last.


How to use

Choose a pot or seed tray with drainage holes.

Fill your container, position your plant or sow your seeds, then water thoroughly until excess water drains away.

If you’re creating your own custom blend, simply combine this mix with one of our specialty soils until you achieve the texture you’re looking for.

No buying multiple ingredients.

No complicated recipes.

Just open the bag and grow.


Watering Tips

No potting mix can completely prevent overwatering.

How often your plants need water depends on the plant, pot size, drainage, light, temperature and humidity.

Instead of watering on a schedule, check the soil first. Water thoroughly, let the excess drain away, then wait until your plant actually needs water again.
