Q.How to stop squirrels digging up bulbs
Every year I plant bulbs and every year squirrels dig them up and eat them or carry them away – except for the grape hyacinths! I would love to grow early daffodils and then tulips. If I plant the bulb, quite deep, in late spring/early summer instead of the autumn would this solve the problem?
Thank you.

No, the bulbs would probably sprout early. Planting them in late fall prevents them from sprouting till the warmth of spring.
