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 Bulb Counts for My Bed", check the chart and you’ll see how many bulbs you need to buy for different types of flowers. Each result lists a range of bulbs so you can choose to plant loosely with less bulbs to show off each specimen or pack them in tight for a big block of color.
Bulb planting tips
- Ensure a beautiful show by planting bulbs at the proper depth — usually three times 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.
- Tools like a bulb auger or hand bulb planter make planting easier.
