Cheat Sheet
Origins of Arbor Day -
The first Arbor Day was celebrated on April 10, 1872, in Nebraska thanks to J. Sterling Morton, who encouraged residents to plant over a million trees on that day (source: University of Nebraska - Lincoln). A handy mnemonic is "Morton's Million Trees" to remember the founder's name and his ambitious planting goal.
Global Arbor Day Dates -
While the U.S. observes Arbor Day on the last Friday in April, countries like Australia celebrate on the last Friday in July and China on March 12 (source: National Arbor Day Foundation). Remember "July for Jumping Jacks in Oz" to recall Australia's sunny planting season.
Optimal Tree Planting Practices -
Plant during dormancy in early spring or fall and dig a hole three times wider than the root ball but no deeper to ensure proper root spread (USDA guidelines). Use the "3×1×1" rule: hole width 3× root ball diameter, depth equal to root ball height, and 1 inch of mulch to retain moisture.
Environmental Impact Metrics -
One mature tree can absorb up to 48 pounds of CO₂ annually and filter over 1,000 gallons of stormwater each year (U.S. Forest Service). A fun way to remember is that a tree "eats" the weight of a candy bar (about 48 grams) per week to fuel its growth!
Arbor Day Fun Facts -
The National Arbor Day Foundation has helped plant more than 500 million trees since its founding in 1972, and in 1970 Congress officially designated the last Friday in April as National Arbor Day (source: National Arbor Day Foundation). Quiz takers can use the phrase "50 by '70" to recall when every state recognized Arbor Day officially.
