The answer to 'how to maintain flower bed' is to regularly maintain and care for your flower beds. This includes weeding, fertilizing, mulching, and deadheading flowers. Proper maintenance will help your flowers thrive and keep your garden looking its best.
Start by weeding the flower bed regularly, at least once a week during the growing season. Pull weeds by hand, making sure to get the entire root system. Next, fertilize the bed 2-3 times per year, using a balanced, slow-release fertilizer. Apply a 2-3 inch layer of organic mulch around the plants to retain moisture and suppress weeds. Finally, deadhead spent flowers to encourage more blooms.
