Soaking seeds in cooled chamomile tea before planting to encourage faster germination

Soak Seeds in Chamomile Tea for Faster Sprouting

Chamomile tea does more than smell relaxing. It can help soften the outer shell of certain seeds, making it easier for them to sprout.

This works especially well for seeds with harder outer coatings that usually take longer to germinate.
