An essential piece of kit for gardeners, seedling trays are the best way to protect tiny seedlings, and begin the planting process. Not only do seedling trays let you sow lots of seeds at once, but many designs can be planted directly into the ground, so you can avoid issues such as transplant shock which can have a negative effect on your plant's growth.
There are a number of different seedling tray options to go for, and in our roundup you'll find peat free fibre pots, bamboo trays and reusable rubber designs - all plastic free so you can keep your garden as green as possible. We've also included a couple of sturdy wooden seedling trays that are ideal for transporting tools, pots, seeds or even a cup of tea, around the garden.

Best seedling trays for 2024
Sili-Seedlings Seed Starter Tray
If you're fed up of thin plastic seedling trays cracking and tearing, you may want to invest in a reusable design made of a more durable material. This silicone option from Sili-Seedlings offers a flexible nature so you can gently ease the soil out without effecting the integrity of the roots.
There are drainage holes on the bottom, and the vibrant green colour is a nice change from the more typical black trays that are commonly used.
It's even dishwasher safe so you can keep your garden equipment nice and clean, ready for the next batch of seedlings. You get two trays in a pack, each with six cells.
Biodegradable Seedling Starter Trays
Opt for a biodegradable seedling tray, and save yourself the hassle of having to remove the soil from the cells before repotting. When germinated, the roots grow through the fibre pot, so you can plant them directly into the soil. An easy, eco-friendly alternative to single-use plastic. You can also cut between the cells and tailor them to your gardening needs.
This set comes with 24 plant labels too so you can keep track of what you've planted. With ten trays, each with ten cells, there are plenty to keep you going for a while.
Grow It Round Fibre Pots
A similar principle, these round, peat free fibre pots can be planted directly into the ground, or into a larger pot if you fancy. The pots are made from biodegradable wood pulp and you get 96 in a pack. Why not plant a cutting and gift to a friend? A pot that you don't need returning!
Natural Rubber Seed Tray
If you're looking for a more robust and reusable seedling tray, you could go for a natural rubber design. Just like silicone, it's a flexible and durable choice. This 20 cell rubber seedling tray can be cut in half - ideal for a narrow windowsill or shelf.
Copper Seed Tray
SQUIRREL_TEXT_13089229
This option is not only a practical way to grow seedlings, but it also makes a beautiful addition to any windowsill or greenhouse. We love the warm copper tones of the tray, and its rustic, aged look.
If you're after a slightly different shape, you could try the longer, shallower brushed copper tray, also available at Crocus.
And if you love the rustic metal look, you might like Crocus's galvanised steel tray with 24 individual grow pods.

Bamboo Seed Tray
The soothing sage colour of this bamboo and rice seedling tray makes it an appealing choice, and it's a super option if you want to plant your seedlings in one large batch rather than working with individual cells. Suitable for both indoor and outdoor planting and as an added bonus, the tray is compositable.
The seedling tray should have a life of around five years, but once you're done, just break it up and add the pieces to your compost heap.
Verve Natural Tray
Buy from B&Q (£2.00), B&Q (£3.70)
For an easy and inexpensive choice, you can't beat these natural trays from B&Q. Just use the Click&Collect option to pick them up at your local store.
These trays are made from recycled paper pulp and you can compost them at home once you've finished.
Spruce Seedling Tray
Buy from Garden Trading (£15.00)
More of a garden tray for carrying fresh garden vegetables, pots and bulbs rather than a tray for sowing seeds, but a lovely garden accessory nonetheless. The tray is made of spruce, and the 'seedling' text stencilled on the side is a nice touch. A perfect gift for a messy gardener in need of some greenhouse organisation.
