How do I calculate how many plants I need?

Measure your garden bed dimensions (length and width), determine the recommended spacing for your plants, then use the formula: plants per row = floor(length / spacing) + 1, total plants = rows x columns. Our calculator does this automatically with visual preview.

What is the difference between square and triangular plant spacing?

Square spacing places plants in a regular grid with equal distance between rows and columns. Triangular (offset) spacing staggers every other row by half the spacing distance, which fits approximately 15% more plants in the same area while maintaining the same minimum distance between plants.

How far apart should I plant a hedge?

Hedge spacing depends on the plant variety. Most hedging plants are spaced 18-36 inches apart. For a dense privacy hedge, use closer spacing or plant in two staggered rows. Formal hedges like boxwood may be as close as 12 inches, while large shrubs like laurel need 24-36 inches.

How deep should I plant bulbs?

A general rule is to plant bulbs at a depth of 2-3 times their height. Small bulbs like crocus go 3 inches deep, medium bulbs like tulips and daffodils go 6 inches deep, and large bulbs like alliums go 8 inches deep.

Can I mix different plants in one garden bed?

Yes! Our multi-zone feature lets you add multiple plants to a single garden layout, each with its own spacing requirements. The visual preview shows different colored circles for each plant zone so you can plan your garden composition.
