I planted Morning Glory seeds in my garden, and now they have sprouted and are starting to grow up the lattice I have placed in the garden. For the past few days, I've noticed that the leaves on the vines have been drying up, and upon further investigation, I've noticed that chipmunks have been biting off the vines!!! I looked at various gardening sites, but have not been successful in finding out how to repel these cute, but naughty rodents. If there are any avid garderners out there, can you offer any suggestions?
