After planting and as soon as soil has frozen to a depth of one to two inches, replace mulch. Some bulbs are bothered by rodents, particularly squirrels, chipmunks, and mice. Daffodils and hyacinths are not bothered. In spring, rabbits feed on tulip and lily foliage. Chicken-wire enclosures or some of the taste repellents work fairly well.
Further care is required in spring.
When bulb foliage has emerged two to three inches and is making rapid growth, hand weed to eliminate competition. After spring cultivation, replenish mulch, if needed, to a two to three inch depth. This conserves moisture, suppresses weeds, and prevents mud splash to blooms. Water is needed especially during bud and foliage expansion. If rainfall is insufficient, apply additional water.
