Calculate how many trees can be planted per acre based on tree spacing distance. Helps plan tree planting for orchards, timber plantations, and reforestation projects.

Trees per acre = 43,560 ÷ (spacing between rows × spacing within rows). For example, with 8×8 foot spacing: 43,560 ÷ 64 = 680 trees per acre.
Square spacing uses equal distances between rows and within rows (e.g., 8×8 feet). Rectangular spacing uses different distances for rows versus trees within rows (e.g., 10×6 feet).
Timber plantations typically use 6×6 to 10×10 foot spacing depending on species. Faster-growing species can handle tighter spacing, while slower species need more room.
Fruit trees typically need 12×12 to 20×20 foot spacing depending on variety. Dwarf trees can be planted closer (8×8 feet) while standard trees need more space (15×15 or 20×20 feet).
Generally yes. Hardwood trees typically need 8×8 to 12×12 foot spacing, while softwoods can often be planted closer at 6×6 to 8×8 feet due to their narrower canopies.
Planting too close is the most common mistake. Trees need space for root systems and canopies to develop. It's better to start with wider spacing than to overcrowd and require expensive thinning later.
The best time varies by region, but generally fall or early spring when trees are dormant. This gives roots time to establish before the stress of summer heat or winter cold.
Tree roots typically extend 2-3 times wider than the canopy. Proper spacing ensures roots don't compete excessively for water and nutrients, leading to healthier, faster-growing trees.
