Hedge Plant Calculator
Calculate how many plants you need for your privacy hedge.
Use decimals when needed. This estimate updates live and is safe to tweak before you buy materials.
Hedge Plant Buying Guide
This guide helps you turn your hedge plant calculator result into a cleaner purchase plan. Use it when you want fewer return trips, better waste assumptions, and a more realistic cart.
Step 1: Check the mature spread
Don't space plants based on how they look in the pot. Space them based on their mature width. If an Arborvitae grows 4 feet wide, plant them 3 feet apart for a dense screen.
Step 2: Consider a staggered double row
For an instantly thick privacy hedge, plant two zig-zagging rows. This requires 50% more plants but blocks wind and sightlines much faster than a single row.
Step 3: Buy uniform sizes
A hedge only looks good if it grows evenly. Hand-select your plants at the nursery to ensure they are all the exact same height and fullness.

Hedge cost planning rule of thumb
In addition to the shrubs, budget for a starter fertilizer, lots of mulch to suppress weeds around the bases, and potentially a soaker hose for irrigation.
Understanding the Math
Formula: The basic formula for Hedge Plant Calculator typically involves calculating the total area or volume (Length × Width × Depth) and dividing by the coverage of a single unit or package, then adding a waste factor (usually 10%).
Example: For example, if you have a 10x10 area and your material covers 10 square feet per unit, you need 10 units. With a 10% waste factor, you should purchase 11 units to ensure you don't run short.

Hedge Plant Calculator FAQ
How far apart should I plant my hedge?
It depends on the mature width of the species. For fast-growing privacy screens like Thuja/Arborvitae, 24 to 36 inches is common to ensure they grow together quickly without suffocating.
What is a staggered double row?
A staggered double row (or zig-zag pattern) requires planting two offset rows. It requires more plants but creates a much denser privacy screen in less time.
How do I take care of newly planted hedges?
Consistent watering is critical for the first year. Installing a soaker hose beneath a layer of mulch is the most effective way to encourage deep root growth.
