Answer: Since rhubarb is a perennial and takes up quite a bit of space (3-4 feet in diameter!), choose a permanent home for it on the edge of your garden or flower border. They make nice specimen plants, too with their colorful leaves and grand flower stalks, soyou don't need to grow it in your vegetable garden if space is at a premium.<br><br>Rhubarb requires at least 5 hours of full sun to produce well, and prefers a deep, rich, slightly acid (5.5-6.8pH) soil. Spread compost around plants in spring and mulch them to keep soil moist. Water soil around plants during dry spells, and foliar feed plants during the growing season for higher yields.
