Unit price perEstimated delivery between November 01 and November 03.
The 9cm Square Plant Pot is a compact 0.5L black horticultural pot designed for propagation, seedlings, rooted cuttings and growing-on young plants. Measuring approximately 9cm across the upper rim, 6.5cm across the base and 10cm high, its square format makes particularly efficient use of valuable nursery, propagation and greenhouse bench space.
Half-litre pots provide a useful next step for plants that have established in plug trays, propagation cells or smaller starter pots. The additional growing-medium volume gives developing roots more room while keeping the container compact and easy to manage.
The square profile allows pots to be positioned closely together, helping growers maximise the number of plants that can be accommodated within a given production area. This makes square pots especially useful for commercial propagation and nursery production where bench-space efficiency matters.
The pot's tapered sides make plants straightforward to remove when potting-on and allow empty containers to nest together for efficient storage.
Suitable for peat-based and peat-free compost, propagation mixes, soil, coco coir and other horticultural growing media, this versatile 0.5L pot can be used by professional growers and home gardeners alike.

- Indoor & outdoor use - suitable for propagation areas, nurseries, greenhouses, polytunnels and gardens.
- Reusable - sound pots can be cleaned and reused for subsequent crops.
- Compatible saucer available - can be used with the 25cm saucer, product code P00110.
Ideal for seedlings & rooted cuttings
The 0.5L capacity makes this pot particularly useful during the transition from propagation into early vegetative growth.
Once a seedling or rooted cutting has developed sufficiently in a plug, cell or starter container, moving it into a 9cm pot provides additional growing medium for continued root development without placing a small root system into an unnecessarily large container.
This makes the pot suitable for rooted cuttings, young ornamentals, herbs, vegetable plants, perennials and a wide range of nursery crops.
As the root system fills the pot, vigorous plants can then be moved progressively into larger containers.
Why use a square plant pot?
One of the main advantages of a square horticultural pot is efficient use of growing space.
Round pots naturally leave gaps between neighbouring containers. Square pots can be positioned much more closely together, allowing growers to maximise plant density across propagation benches, nursery beds and greenhouse growing areas.
This can be particularly valuable during early production when large numbers of young plants need to be maintained within a limited area.
Square pots can also simplify orderly spacing and help create uniform nursery layouts.
9cm Square Pot dimensions
The pot measures approximately 9cm x 9cm across the upper rim, 6.5cm x 6.5cm across the base and 10cm high.
These proportions provide a nominal capacity of approximately 0.5 litres, giving young plants useful root depth while maintaining a very compact production footprint.
The tapered sides also make empty pots easy to stack and nest for efficient storage.
What can you grow in a 0.5L square pot?
The 9cm Square Pot is suitable for propagation and early-stage production of a broad range of plants, including:
- Rooted cuttings
- Seedlings
- Young herbaceous perennials
- Herbs
- Bedding plants
- Young vegetable plants
- Young chilli and pepper plants
- Strawberry plants
- Young ornamental plants
- Young shrubs
- General nursery stock
For most vigorous crops, 0.5L should be regarded as an early growing-on size rather than the final container.
Suitable growing media
The 9cm Square Plant Pot can be used with a wide range of propagation and horticultural substrates, including:
- Seed and propagation compost
- Peat-based nursery compost
- Peat-free growing media
- Soil-based potting mixes
- Coco coir
- Coco and perlite blends
- Other suitable propagation and horticultural substrates
Select a growing medium appropriate for the crop and stage of development. Young root systems generally benefit from a substrate that combines reliable moisture retention with sufficient air-filled porosity.
Watering small 0.5L pots
Smaller pots contain less growing medium than larger containers and can therefore respond quickly to changes in temperature, light levels and plant water demand.
Check substrate moisture regularly rather than watering solely according to a fixed timetable. As plants become established and develop larger leaf areas, they may use the available water increasingly quickly.
Conversely, newly potted young plants with small root systems may initially use relatively little water, so avoid keeping the growing medium unnecessarily saturated.
The pot is suitable for hand watering and compatible nursery or propagation irrigation systems.
Compatible with the 25cm Pot Saucer
The product information specifies compatibility with the 25cm Pot Saucer, product code P00110.
The saucer measures approximately 25.5cm across the rim, 21.5cm across the base and 4cm high.
Because the saucer is considerably larger than an individual 9cm pot, it can provide a useful runoff-catching surface beneath the container rather than being a close-fitting individual saucer.
A saucer is particularly useful indoors or on protected surfaces where irrigation runoff needs to be contained. It may not be required in free-draining nursery or outdoor growing areas.
Space-efficient nursery production
The combination of a compact 9cm footprint and square shape makes this pot particularly useful where large numbers of young plants need to be accommodated efficiently.
Pots can be arranged in neat rows with minimal unused space between them, helping growers make better use of greenhouse benches and propagation areas.
Plants remain lightweight and easy to move, grade and reorganise as the crop develops.
When should you pot on from a 9cm pot?
There is no fixed number of days or weeks that a plant should remain in a 0.5L pot. Potting-on should be based on root development, plant size and irrigation demand.
A well-developed root system throughout the growing medium, increasingly rapid drying or vigorous growth relative to the container can indicate that the plant is ready for additional root volume.
Progressive potting into an appropriately larger container helps maintain manageable moisture conditions while allowing continued root development.
Practical & reusable
Pots that remain in sound condition can be emptied, cleaned and reused for subsequent crops.
Remove old growing medium and root debris before cleaning. Where propagation pots are reused between crops, appropriate hygiene is particularly important to reduce the risk of transferring pests or plant pathogens to young plants.
The tapered profile allows empty pots to nest together for compact storage.
