Mind the bulbs. Spring bulbs such as tulips and daffodils put on quite a show, but once they're done it's important to remove their spent flowers to help preserve energy for next year's bloom. Simply cut each finished flower stalk at the base. Don't be tempted to cut down the foliage, however. The plant will naturally die back over the coming months and will slowly reclaim the nutrients in the foliage to store in the underground bulb. Once the foliage is withered and brown, you can rake it away.
