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! Add multiple plants, then choose how much of the bed each one receives. The calculator divides the bed into labeled planting areas and calculates every plant only within its share, so the total and preview describe one real mixed layout.
