3. Keep it moist

Keep it warm and evenly damp, not soggy. Once it sprouts, give it light; a sunny window works.

Jiffy Pellet Questions

What is a Jiffy pellet?

A Jiffy pellet is a flat disc of compressed peat moss held in thin netting. Soak it and it swells into a small, ready-to-plant seed pot. You sow a seed right in it, then plant the whole pellet when the seedling is ready.

What size are these pellets?

These are the large 50mm (about 2 inch) Jiffy peat pellets. The bigger size gives roots more room and holds more moisture than the smaller pellets most stores sell, so seedlings can stay put a little longer.

How long do I soak a Jiffy pellet?

About 15 minutes in warm water, or until it is fully expanded. Cold water takes longer. If the middle still feels hard, give it a gentle squeeze and wait a few more minutes. Pour off any extra water before you plant.

How deep do I plant the seed, and how many?

Plant about 1 cm (a little under half an inch) deep and cover lightly. Many gardeners sow one to three seeds per pellet and keep the strongest seedling. One fresh seed per pellet is fine. Tiny seeds need less cover, so check the packet.

How often do I water a Jiffy pellet?

Keep it damp, not soggy. Water from below: add a little water to the tray when the pellet turns lighter brown or feels light. A clear cover helps hold moisture until the seed sprouts; take it off once it does.

Do I take the netting off before planting?

Most gardeners plant the pellet whole, and roots grow through the thin netting. If roots look crowded, you can gently slit the netting before you plant. Bury the pellet fully so the top does not dry out.

When do I transplant the seedling?

When roots show at the netting and the seedling has its first true leaves, usually a few weeks after sowing. Plant the whole pellet and firm the soil around it. Harden plants off first if they are going outdoors.

Can I buy just one pellet?

Yes. Choose 1 pellet to fill an empty slot or test a new seed. Starting a full tray? The 16 and 36 packs cost less per pellet. Many stores only sell multipacks, so this is the easy way to get exactly what you need.
