It's basically taking say 3 or 4 lots of bulbs and starting with planting the first layer about 12 inches down (tulips will have no problem with this), then cover those with 2-3 inches of compost or so, add another layer and continue until you've covered the topmost layer. That way you get more bang for your buck!
Here Crocus Jeanne D'Arc takes centre stage.
The tulips take over.
Then the peak display. Tulips are Labrador, Mascotte and Honeymoon.
