Plant Pot Size Guide

Pot sizes are listed in litres capacity. They are usually black plastic, although an increasing number are being grown in taupe coloured pots to enable waste pots to be collected at the roadside.

Please note the above guide is for illustration purposes only and are not sized proportionally to one another.

9cm – We generally use our P9 pots to grow our stock on from, our most common p9 lines are Ilex aquifolium and some herb and herbaceous lines. Our p9 pots are generally square.

2L – Our 2L pots are ideal for the production of amenity plants grown for one year, most commonly used for our 2L herbaceous and shrub lines, this size is great as the plants are small enough to establish but large enough to make an impact when first planted.

3L – Slightly larger than a 2L, we generally use these for our garden centre plants and some amenity lines.

5L – A 5L is Ideal for the production of bigger shrubs with a larger root capacity, these can be seen across our nursery but generally found within our garden centre sales.

10L – This is our most common pot for ‘specimen plants’ that have generally been grown for two years +.

20L – Used for specimen shrubs such as Rhododendron and conifers and some small trees.

They do make this confusing, don’t they? There’s a theory going around that this purposely confusing system is a way for the mass market industry to charge more for plants, by container size, not necessarily Plant Size!

So let’s try and break down these various sizes and measurements and set some general “accepted standards” for pot sizes. Please remember these are rough estimates and not a science.
