Seed Starting In Coir: Using Coconut Coir Pellets For Germination

Starting your own plants from seed is a great way to save
money when gardening. Yet dragging bags of starting soil into the house is
messy. Filling seed trays is time consuming and the sterilization needed to
prevent disease is a lot of work.  If
only there were an easier way…

Coir Discs for Seed Planting

If you enjoy raising your plants from seed but hate the
hassle, you might want to try coir pellets. For germination of seeds, pellets
are an easy, fast and clean method. When compared to peat pellets, coir discs
for seed planting are an eco-friendly option.

Although peat is a natural material, it’s not considered a
sustainable product. Peat is the decaying remnants of sphagnum
moss
. It takes hundreds of years to form peat bogs and considerably less
time to deplete them.

On the other hand, coir pellets are made from the husk of coconuts.
Once considered an agricultural waste, this coconut fiber is soaked and treated
to remove excess minerals. It’s then formed into flat, round discs and sold as
a seed starting product by various manufacturers.

Benefits of Seed Starting in Coir

In addition to being less messy, coir discs virtually
eliminate the problem of damping
off
. This fungal infection can be transmitted through soil and unsanitary
starting trays. It most often attacks newly sprouted seedlings, causing the
stems to weaken and the plants to die. Wet conditions and cool temperatures
contribute to the problem.

Coir pellets for seed planting are fungus free. Coir readily
absorbs and holds water, yet doesn’t become supersaturated and soggy. The
material remains loose for improved root formation and the netting surrounding
the ground coconut hulls retains the shape of the pellet.

How to Use a Coconut Pellet Seed Starting System

  • Expand the pellets – When using coir pellets for germination of seedlings, the dry flat disc must be soaked in water. Place the pellets in a waterproof tray. Make sure the small imprinted hole is facing up. Pour warm water over the discs and wait for them to expand.
  • Sow the seed – Once the pellets are fully expanded, place 2 seeds in every pellet. The planting depth can be controlled by pinching or compacting the pellet. Be sure to label the tray for identification of seedlings. Use a clear plastic lid or plastic wrap to retain moisture.
  • Provide light – Place the trays under grow lights or near a sunny window. Keep the pellets evenly moist while the seeds germinate. Adding a little water to the bottom of the tray once a day is usually sufficient.
  • Germination – Once the seeds have germinated and the cotyledons have opened, it’s best to remove the plastic cover. Continue to water once daily to keep the pellets evenly moist.
  • Provide nutrients – By the time the seedlings have their second or third set of true leaves, the roots are usually penetrating the netting. For tall, healthy transplants, it’s best to either fertilize at this time or plant the seedlings, pellet and all, in a small pot.
  • Transplant seedlings – When the seedlings are ready for transplant, harden off the plants. Coir pellets can be directly planted into the garden.
