How to Replant the Root End of Celery
Growing a windowsill garden from kitchen scraps is a frugal and delicious science experiment for children. With a few recycled containers, potting soil and a selection of scraps and seeds, your children can experience first hand the joy of gardening -- no matter where you live. As long as you have light, soil and water, your scraps will grow. One interesting vegetable to resprout is the celery, with its layers of stalks and leafy top.
Cut off the base of the celery, 1 1/2 inches above the root. Set the base aside, root side down, in 1/2 inch of water.
Punch a few holes in the bottom of a large cottage-cheese container. Set the container inside a second intact container. Fill with potting soil and add water, allowing it to soak into the soil.
Take the celery base out of the water and settle it gently into the moist potting soil. Mound a little soil around the sides of the celery; do not cover the top.
Place in bright filtered light. Keep the soil moist but not soaking wet. The celery base will sprout new roots and leaves in a week or two. Once the celery is actively growing, transplant to a flower pot or into the garden.
Replant The Root End Of Celery
Save the root end of the celery plant when you have used up all the stalks for cooking. Fill the plant pot to about an inch from the top with potting soil, and make a depression in the center of the soil the same diameter as the celery root. Place it in the plant pot and push it down very gently into the soil, being careful not to separate the root-end stalks. Plant celery roots outside in areas where summers are longer and warmer, which is generally from July to September. Begin harvesting the tender young celery when the new stalks, which will appear in the center of the root, are about 3 inches tall. This encourages new growth to continue.
Rooting hormone is not necessary.
Leave the celery in water for several days so the children can watch the roots grow.
Carrots and pineapple tops are similarly propagated. Pineapples must dry out for a few days before settling the green top into a large flower pot for sprouting.
Do not put celery in the hot sun. Celery prefers mild temperatures.
