Jiffy Seed Pellets Instructions

Related Articles

Seed pellets, sometimes called peat pellets, provide an alternative to the standard seedling pot when you start your garden transplants indoors. Jiffy, a brand of seed pellets, uses peat and coconut coir as the primary growing medium. In their dehydrated, compressed form, the pellets store well. With the addition of water, they quickly turn into a container and growing medium for your seedlings.

Preparation

Seed pellets have a biodegradable net covering that helps them retain their shape once they expand. The netting fully encases the pellet on all sides but the top. The pellets must set in a tray that helps keep them upright once expanded. Arranging the pellets on the tray with the non-netted side on top ensures they are ready to plant once you add water. Fill the tray with 1 inch of water and allow the pellets to fully absorb the moisture and expand to their full height of about 3 inches. It can take the pellets 30 to 60 minutes to fully absorb the water, and in dry conditions, they may require more water to completely hydrate. If excess water remains in the tray, empty it before you plant.

Planting

Once hydrated, pellets perform just like a seedling pot filled with soil. Seeds are sown to the proper depth in the top of pellet, usually with two seeds planted in each pellet in case one seed fails to germinate. Covering the pellets with a layer of plastic wrap retains moisture during germination, so the pellets won’t require any additional watering until the seeds sprout. Once the first seedlings emerge, the plastic is removed and the plants require basic care to continue to growing well.

Seedling Care

Most indoor-grown seedlings require six to eight hours of sunlight, so place them near a sunny window. The peat mixture in the pellets retains moisture well, but the plants will need watered when the pellet surface begins to dry. Pouring 1 inch of water into the tray allows the pellets to absorb the amount of moisture they need. Once the pellet surface becomes moist, the remaining water is emptied from the tray. The Jiffy brand pellets contain fertilizer to feed the seedlings until transplanting, so no additional fertilization is necessary. If both seeds sprout, pinch out weaker the plant when the stronger plant develops its second set of leaves.

Transplanting

Transplanting time depends on the specific plant, but most seedlings are moved to the garden when they are four to six weeks old and after frost danger is past. The pellets don’t require preparation before planting. The peat in the pellets can wick moisture away from the plant if it’s exposed. Avoid this issue by planting the pellets so the top surface is covered with a thin layer of garden soil. The netting and pellets break down as the plants grow.

how long can seedlings stay in peat pellets

Think of them like a sponge. every bit of moisture in the soil will be wicked into them.

Thanks to all for any advice.
I am starting from seed the first time this year and am using primarily peat pellets as my growing medium. Germination is great, growth is great. My leeks looked like they might be outgrowing the pellets (I could see roots coming out the bottoms), so I decided to put the peat pellets in small peat pots (on top of a small mound of Jiffy mix, then filled in with the sam). Most of my leeks then wilted over and died. I’m thinking their roots were lacking water in their new situation. I usually bottom water and sprinkle a bit on top for good measure. My questions are:

Peat pots will suck the moisture out of the soil quicker than you can bat an eye. throw those away.
I don’t know what happened to your leeks, but I do start a lot of seeds in peat pellets and then pot up to 4″ plastic pots before transplanting outside. I haven’t had any problem with plants dying doing this. Sometimes I get busy and don’t pot them up very quickly, but the seedlings will continue to grow with their roots coming out the sides of the pellets if they are in trays. They do grow into other pellets, but I hate to say this, I just rip them apart (ow!) and plant them and they are always fine. IME, there is no such thing as transplant shock. I grow all sorts of plants – herbs, flowers, perennial, veggies – but I have never grown leeks. Maybe there is something about them that didn’t like the peat.
2. Is there a better way to move peat pellets to a larger interim container before planting out?
Any type of plastic cup that you can poke holes into (make sure you have some holes on the bottom of the sides, too) will work. and when you pot up, switch to a good potting soil/peat mixture. not just peat.
1. Did I need to move my leeks to bigger pots, or would they have been fine in the peat pellets for a good while longer?

I used to use the peat pots but they were hard to get, so I switched to plastic and like it better because I can reuse them year after year. I bought a whole bunch from either Fedco or Peaceful Valley couple years ago.
