About this product
Full description
The 9cm square pot is the workhorse of serious propagation — the size you reach for when seedlings are ready to leave their starter trays, when cuttings have rooted and need their own space, when plug plants arrive and need somewhere to grow on. They fit standard seed trays in neat rows, they nest cleanly when empty, and a serious propagation setup needs them in proper quantity.
These are Garland 9cm Vegetable Tray Pots — properly considered everyday propagation kit from a British horticultural manufacturer who've been making this kind of thing since 1968. Made in the UK from 100% recycled plastic, fully recyclable at end of life, and designed to last several seasons of regular use with a bit of care.
From Garland, the established British horticultural brand specialising in propagation, greenhouse and growing equipment. Made in the UK since 1968.
What they're for
The 9cm square pot is the standard "potting-on" size in serious propagation — generous enough for proper root development, compact enough to fit dozens in a propagator or cold frame:
- Potting on vegetable seedlings — tomatoes, peppers, chillies, courgettes, brassicas, salads, herbs after their initial seed-tray stage
- Striking and growing cuttings — softwood, semi-ripe, herbaceous cuttings of all kinds. Ideal for geraniums, fuchsias, herbs, cottage garden perennials
- Growing on plug plants — bringing them up to a planting-out size before final move
- Sowing larger seeds individually — beans, peas, sunflowers, sweetcorn, where each seed wants its own pot
- Container herbs — many smaller herbs are happy living long-term in a 9cm pot on a kitchen windowsill
- Replacement and expansion for existing propagation setups, where pots have cracked, warped or been lost
If you're serious about propagation, you'll go through these in volume during spring. Buying ahead in proper quantities is far more sensible than topping up in twos and threes from the garden centre.

The recycled plastic story
These pots are made entirely from recycled plastic — the raw material has had at least one previous life elsewhere before being remade into propagation kit. At end of life, they're recyclable again, so the material stays in circulation rather than ending up in landfill.
For propagation kit (which broadly has to be plastic if it's going to last multiple seasons — fibre pots are wonderful but not infinitely reusable), recycled-plastic construction is genuinely the best of a difficult choice. It uses no new petrochemical material, keeps existing plastic out of waste streams, and delivers the durability that fibre pots can't match for repeat-season use.
Looking after them
Garland rate these for 2–3 seasons of regular use. With a bit of small care, that's genuinely achievable — and the longer the pots last, the better the cost-per-use calculation becomes:
- Wash between seasons — a quick wash with hot soapy water removes compost residue, root marks and any potential disease carryover. Particularly important if you've grown anything diseased in them previously
- Air dry properly before stacking for storage — damp pots stored together encourage mould
- Stack carefully — over-tight stacking can crack the pots over time. Loose stacking with occasional rotation extends their life
- Store out of direct sunlight — UV degrades plastic over time, so a covered shed beats a sunny windowsill for storage
- Replace when they crack — recycled-plastic pots eventually fail, and a cracked pot loses its structural integrity for proper root growth
Treated this way, you'll genuinely get the rated 2–3 seasons out of them.
Tray pots vs fibre pots — choosing the right pot for the right plant
We stock both these durable tray pots AND our 8cm biodegradable fibre pots. They serve genuinely different purposes:
- Choose these 9cm tray pots for: heavy-use propagation across multiple seasons, potting-on vegetables and herbs, growing on plug plants, striking cuttings, when you want the same pots back next year
- Choose our 8cm biodegradable fibre pots for: root-shy plants (sweet peas, beans, poppies), plant-the-whole-pot convenience, peat-free sustainable approach, when transplant shock matters most
Most serious propagators eventually keep both — the tray pots as workhorses for everyday potting-on, the fibre pots for the root-shy specialist sowings.
Particularly good for
- Serious propagators — if you raise a lot of plants from seed or cuttings, you genuinely need these in volume each spring
- Vegetable growers — tomato, pepper, chilli, brassica seedlings all need potting-on at this size
- Cottage garden growers — for raising annuals to planting-out size, growing on perennial cuttings, herb propagation
- Allotmenteers — the cost-effective scale for raising your own plants rather than buying plug plants
- Cuttings enthusiasts — the right size for rooted softwood and semi-ripe cuttings
- Greenhouse growers — nest cleanly on staging, fit standard seed trays, properly the workhorse size
- Long-term sustainability gardeners — reusable across multiple seasons, made from recycled material, fully recyclable
- Replacement buyers — if your existing pots are wearing out, these are the standard replacement size
- Container herb growers — herbs like basil, parsley, mint do well long-term in 9cm pots

Together with our seed range, biological pest controls, and temperature monitoring, this is the complete indoor-to-outdoor growing system.
About Garland
Garland is an established British horticultural brand specialising in propagation, greenhouse and growing equipment, manufacturing in the UK since 1968. They've supplied UK growers for nearly six decades with the practical kit that makes indoor and outdoor gardening work properly. Their products are widely used in commercial nurseries as well as home gardens. We stock their range because they make tools that genuinely improve outcomes for the home grower.
A small thought: propagation is one of the gardening pleasures that rewards proper kit. The right pot, in the right size, in the right quantity, lets you sow with confidence rather than stretching a too-small selection across too many seedlings. These aren't fancy, they aren't beautiful, and they don't need to be — they're the everyday workhorse that quietly supports the work that fills your garden by July.
