Q.how to plant the seeds of a kumquat
Do you soak the seeds in water? Do you plant them in a pot first or in the ground? What type of fertilizer do you use?
You will not need to soak your seeds, plant them directly from the fruit. Start the seeds in a small starting pot in a potting mix.
Keep your seed moist and warm while it germinates. Then as your seedling grows you can move up the pot size.
