Wondering how many bulbs to buy? Find out with our bulb calculator. Calculate the size of your garden bed here first. Then add that number to the "square feet" box below. Click "Calculate", check the chart and you’ll see how many bulbs you need to buy. Each one has a range so you can plant loosely to show off each specimen or pack them in tight for a big block of color.

Ensure a beautiful show by planting at the proper depth — usually three time the height of the bulb is just fine. Also, if you’re packing them in tight keep bulbs close but not touching. That way if one rots it’s less likely to spread to its neighbors.
