Celery: The next time you chop celery, save the crown (the bottom), place it in a shallow bowl of water until the center leaves turn green and sprout, then transplant it into your garden. Or, just plant the crown straight from crisper into garden, keeping the top of the crown at soil level. Not only is celery a yummy vegetable, it attracts beneficial insects that keep unwanted bugs at bay.
Garlic: Separate cloves and plant the largest ones pointy-side up, under about 2 inches of rich, well-drained soil. Plant garlic around roses to reduce black spot and sooty mold.
Horseradish: In the fall, plant the tuberous horseradish roots horizontally under 2 inches of soil that’s been well-worked with compost. The plant is invasive and spreads quickly, so plant at the end of garden rows or in areas where they have room to wander. Harvest with a pitchfork in late fall.
Ginger: Select a plump ginger rhizome with many small, growing buds. Plant just under rich soil in a spot with filtered sunlight and wind protection. Avoid planting in low-lying areas, or in spots with poor drainage.
