Unit price perEstimated delivery between November 01 and November 03.
The 20L Round Plant Pot is a large black horticultural grow pot designed for established plants, shrubs, larger ornamentals and productive edible crops. Measuring approximately 35.5cm across the upper rim, 27.5cm across the base and 29cm high, it provides generous root volume while retaining the practical tapered shape of a professional nursery container.
With approximately 20 litres of growing-medium capacity, this pot is well suited to plants that have progressed beyond smaller nursery containers and need substantially more room for continued root and canopy development.
The wide upper opening makes potting, top-dressing and checking the growing medium straightforward, while the tapered profile helps established root balls release from the container when plants need repotting or transplanting.
Suitable for peat-based and peat-free compost, soil mixes, coco coir and other appropriate horticultural substrates, the 20L Round Pot is a versatile choice for professional nurseries, greenhouses, polytunnels, indoor growing and home gardens.
Why choose the 20L Round Plant Pot?
- 20 litre capacity - generous root volume for established and larger plants.
- 35.5cm upper rim - wide opening makes planting, top-dressing and maintenance straightforward.
- 29cm high - useful substrate depth for substantial root development.
- 27.5cm base - tapered profile provides a practical nursery-style container shape.
- Versatile growing pot - suitable for ornamental, edible and nursery crops.
- Ideal for potting-on - useful for plants progressing from smaller intermediate containers.
- Suitable for peat-free media - compatible with modern peat-free growing substrates.
- Suitable for coco - can be used with coco coir and coco-based growing systems.
- Indoor & outdoor use - suitable for nurseries, greenhouses, polytunnels and gardens.
- Professional nursery format - practical for growing-on larger plants and nursery stock.
- Reusable - sound pots can be cleaned and reused for subsequent crops.
- Compatible saucer available - fits the 40cm saucer, product code P00082.
Generous 20 litre root volume
Moving a plant into a 20L container gives its root system substantially more growing-medium volume than smaller nursery pots. This can support larger plants, longer growing periods and crops with greater water and nutrient demand.
The additional substrate also creates a larger moisture and nutrient reserve. This can make a well-established 20L container less prone to the rapid drying associated with very small pots, although irrigation requirements will still depend heavily on crop size, substrate and growing conditions.
For many ornamental and edible crops, 20L can serve as a substantial final container. Particularly vigorous or long-lived plants may eventually benefit from an even larger pot or permanent planting position.
What can you grow in a 20L pot?
A 20L plant pot provides enough root volume for a broad range of established plants and container-grown crops, including:
- Tomato plants
- Chillies and peppers
- Aubergines
- Established herbs
- Patio fruit and vegetable crops
- Herbaceous perennials
- Established ornamental plants
- Young shrubs
- Climbing plants
- Small fruit bushes
- General nursery stock
Final pot size should always be selected according to the mature size, vigour and expected growing period of the individual plant.
Ideal for potting-on established plants
The 20L Round Pot is particularly useful when plants have developed substantial root systems in smaller containers and require additional space to continue growing.
Signs that a plant may need potting-on include roots extensively occupying the existing container, increasingly rapid drying after irrigation, restricted growth or a plant becoming disproportionately large compared with its current pot.
When potting-on, use an appropriate fresh growing medium and position the existing root ball at a suitable depth before filling around it. Water appropriately after transplanting to settle the new substrate around the root zone.
Suitable growing media
The 20L Round Plant Pot can be used with a wide range of horticultural growing media, including:
- Peat-free compost
- Peat-based nursery compost
- Soil-based potting mixes
- Compost-based growing media
- Coco coir
- Coco and perlite mixes
- Living soil mixes
- Other suitable horticultural substrates
Growing-medium structure becomes increasingly important in larger containers. Choose a substrate that provides an appropriate balance between moisture retention, aeration and drainage for the crop being grown.
Watering plants in 20L containers
Larger pots contain considerably more growing medium than small propagation containers, so irrigation should be matched to both the size of the plant and how extensively roots have colonised the substrate.
A newly transplanted plant may not immediately use moisture from the entire 20L volume. Avoid repeatedly saturating a large volume of unrooted substrate simply because the surface appears dry.
Once a large plant becomes fully established, water demand can increase considerably, particularly during warm weather or periods of rapid vegetative, flowering or fruit development.
The container is suitable for hand watering and compatible nursery, greenhouse and drip irrigation systems.
Fits the 40cm Pot Saucer
The 20L Round Plant Pot is listed for use with the 40cm saucer, product code P00082.
The compatible saucer measures approximately 41cm across the rim, 37.5cm across the base and 6cm high.
A saucer is particularly useful where large container plants are grown on greenhouse benches, patios, indoor surfaces or other areas where irrigation runoff needs to be collected.
Unless using an irrigation method specifically designed around standing water, avoid leaving the root zone permanently sitting in stagnant runoff.
Suitable for nursery & greenhouse production
The 20L format provides professional growers with a substantial container for finishing larger nursery plants or holding established stock before sale or transplanting.
Its conventional round, tapered profile makes it straightforward to arrange, handle and reposition plants as crop spacing requirements change.
As plants develop larger canopies, adequate spacing between pots can help improve airflow, light interception and access for irrigation and crop maintenance.
Reusable horticultural grow pot
Pots that remain in sound condition can be reused for subsequent crops, making them a practical choice for nurseries and growers with repeat production cycles.
Remove old roots and substrate residue before cleaning. Where pots are transferred between different crops, suitable hygiene procedures can help minimise the transfer of pests or plant pathogens.
The tapered shape also allows empty pots to nest together, reducing the storage space required when they are not in use.
