Gardeners can find a wide selection of spring bulbs for planting right now. The earlier the bulb goes into the ground the longer it will have to establish before cold soil temperatures arrive. Even if you end up planting spring bulbs with your parka on, the bulbs will still show up and bloom next spring. Bulbs will be planted based on their diameter, bigger bulbs deeper, smaller bulbs much closer to the surface. A general rule of thumb gardeners follow is 2-3 times as deep as the bulbs diameter, unless there are planting instructions stating otherwise.
