When to plant bulbs

This week I was asked when to plant bulbs.

Well, it depends.

Some bulbs need to be planted six weeks before it starts freezing, so that's before winter.
When you're not sure, then follow another rule.
The ground should be to 55°F, that's 12°Celcius or cooler.
When the soil is too warm or moist the bulbs will start to rot.

Some bulbs can be planted in spring.
It will say so on the package.

When you're not sure, buy bulbs in containers and put them outside at the time their collegues bloom.
Never ever put them outside just like that.

First water them and keep them in a cool area with temperatures above freezing for a few days.
When the narcisses and tulips are flowering you can put them in the ground.
Remove the container and plant the bulbs in the ground. Not too deep, but at the same level from the top as they were in the container.
