If some of your bulbs fail to send up shoots or the foliage looks a bit worse for wear, hungry critters may be to blame. Here are some tips to help keep your bulbs from becoming a free meal: Rabbits. One of the most effective ways to keep rabbits from nibbling at new shoots is to install a temporary wire fence using inexpensive, readily available chicken wire. (You may have seen green, plastic garden fencing at your local garden store. It may look nicer, but rabbits can easily chew through this material.) To keep rabbits out, you'll need a roll of 2-foot-tall chicken wire and several plastic, metal or wooden stakes.
Start by weaving a stake through one end of the chicken wire and pushing the stake into the ground until secure. Place a stake every 8 to 10 feet, working your way around the bulb planting area. Once the wire fence is in place, use tin snips to cut the wire and fasten the overlapping ends together. (Be sure to wear gloves when working with chicken wire.) You may want to adjust some of the stakes to neaten the shape of your fence.
To discourage rabbits from burrowing under the fence, bury the bottom of the fence a couple of inches below soil level or put landscape timber around the base of the fence. This temporary wire fence can be removed once the tender, young shoots are mature--when the blooms are just about to open on most of the plants. At this point the plants will no longer be so tasty to rabbits, and they will look elsewhere for a snack.
