Am thinking about bulb planting soon. Mainly alliums and tulips. Last year my bulbs were a failure as most of them were dug up by squirrels. Every time I looked out of the window a squirrel seemed to scamper past with one of my bulbs in its mouth. Where did I go wrong? Too shallow? Too early/late? (planted in the last week of Oct). Only been in the house a year and inherited a completely bare garden, so wd love to see things come up this time! Any tips gratefully received!
