Whilst standing in a queue at the local Post Office just before Christmas 2007, I overheard a conversation between a lady and gentleman about the problems of having squirrels invading newly planted pots of bulbs. I joined in on the conversation as a colleague at work, who shares my love of gardening, was experiencing the same problem with her bulbs and the local squirrel population. The lady in the queue suggested using good old fashioned moth balls to deter the squirrels. Just plant the moth balls about 1 and a half to 2 inches below the soil level and the squirrels will apparently leave the pots alone. I passed on this information to my work colleague. She purchased some moth balls, tried it out and it worked! I don't know how long the moth balls last in the soil, (do they dissolve when it rains?) but its worth a try. Perhaps future contributors who give this method a go could let us know?
On another note, I have a large wildlife pond in my garden. Last week I counted 22 frogs paired off and waiting at the bottom of my pond for the opportune moment to spawn. On 2nd March (Mothers' Day)the first two clumps of spawn were laid and kicked off the process. The frogs are now spawning like mad! I have had frogs and hedgehogs in my large garden for a number of years and these helpful creatures keep the population of slugs and snails at bay. Woe betide any who visit my home and tries to chew my plants!
