Seed Trays & Propagators

Nurture Your Plants with Our Seed Trays

Give your seeds & bulbs the best possible start by sowing your seeds in plant trays & propagators. Seed trays are an essential piece of gardening kit to have in your potting bench or greenhouse, letting you keep your seedlings separate before planting out into pots & planters or straight into the ground in a raised bed.

Starting your own seeds at home couldn’t be simpler with our plant trays, available in a range of sizes. Simply stock up on your seeds, fill your seed trays with compost and plant away! Don’t forget to nurture your new crops by keeping them well-watered – a handheld garden sprayer is ideal for this to make sure the small seedlings don’t get waterlogged.

FAQs

What is a seed tray?

A seed tray is a container with perfectly sized compartments for planting seeds and giving them a head start before transplanting outside into flower beds, plant pots, or planters.

How long can seeds stay in seed trays?

Most seedlings outgrow their seed trays in about 4 to 6 weeks, depending on the plant's growth rate.

Do seed trays need holes?

Yes, seed trays need drainage holes. This creates the right moisture balance for the seeds to germinate.

Should I put water in the bottom of the seed tray?

Watering your seed tray from the bottom is good for uniform watering, though it depends on your gardening style. This will also give the seedlings' soil time to breathe without remaining overly wet.

How deep do seed trays need to be?

Most seed trays have a standard depth of 2 to 3 inches. Seeds known for long taproots, such as sunflowers, may need to be planted into deeper pots to accommodate the roots.

Do seed trays need ventilation?

Ventilation isn't strictly necessary, but it can improve growing conditions like a tiny greenhouse! Just remember to remove the cover once the seeds start germinating.
