Plant Calculator

This plant and landscaping calculator makes it easy to figure out how many plants you need, spacing, and coverage.

Fill in any two fields and this tool will calculate the third field.

Use this tool to determine:
  • How many plants do you need to cover a specific area? (Enter Area and Spacing)
  • What spacing best fills an area with a specific number of plants? (Enter Area and Number of Plants)
  • What area would be filled by a specific number of plants at a specific spacing? (Enter Spacing and Number of Plants)
Note: given proper nurturing, the center of the spacing range that we suggest on the "Specs" tab of each plant will generally result in good fill within two years. Use a closer spacing if you wish them to fill in more quickly. Farther spacing is a more economic choice, provided you are willing to wait longer for them to fill in. Plantings in northern zones will of course take longer, as the growing season is shorter.
