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 do not hesitate to contact us if you have any questions on 01423 330234.

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.

GIANT ROUND PLANT POTS

We also offer a very competitive range of giant plastic plant pots. These are more specialised and ideal for larger specimen plants, bamboos and trees. They are extremely strong made from recycled black rubberised plastic and are very sturdy. The pots are pre-drilled with drainage holes in the sides and base and are generally wider than they are deep providing the stability required for larger plants. When planted, these pots are left in situ hence no handles.

These giant plant pots are available in the following sizes.
160 litre 80cm Diameter x 51cm Height
210 litre 80cm Diameter x 55cm Height
230 litre 85cm Diameter x 55cm Height
285 litre 95 cm Diameter x 55cm Height
350 litre 95cm Diameter x 73cm Height
500 litre 103cm Diameter x 80cm Height
