Patio and garden calculators

Garden Bed and Patio Planning

Tools for the planting beds and the seating area: how many plants fit a bed at the spacing you choose, what a square foot garden holds, which patio umbrella suits a table, what a pergola adds up to, and what a whole-yard project costs at your own prices.
