Mine don't have tops yet; I just planted them a couple of days ago, very shallowly with the tips of the bulbs sticking out of the ground. Something dug most of them up and scattered them about last night. (I bet it was a squirrel.)

Here in NY we plant bulbs in the fall, they begin to grow in spring as soon as the ground thaws. Until they become established newly planted bulbs should be covered with some sort of wire screen that can be removed once more mature growth is achieved.

I checked on the onions today and a few of them were dug up again (grrr), but not the whole row this time. A robin flew away as I went out there; I bet he was pulling them up and I just thought it was a squirrel. And it might be a bird picking the tops off of EVP's onions.
