As you prepare to plant a tree, breaking up the soil effectively will ensure proper root growth for the new tree. Because a tree's roots must spread far and deep to nourish the growing tree adequately, a loose soil will enable the tree roots to grow as they should. Use a rototiller to prepare the planting site before you dig a hole for your new tree and you can prepare the planting area quickly.
Determine the planting area where you wish to plant the tree. Plan to cultivate the soil in an area that spreads out approximately 4 to 6 feet from the center spot where you will dig the hole for the tree.
Check the area for large rocks and stones or any other kinds of debris before you rototill. Remove any debris you find.
Set the tilling depth of the rototiller to at least 6 inches (deeper if possible). Position the rototiller on the edge of the spot where you will cultivate and prepare to start the rototiller. Start the rototiller and carefully engage it so it begins moving forward.
Guide the rototiller across the planting area with your hands firmly on the handles. Turn the rototiller around to make a second row, overlapping your rows slightly to ensure complete cultivation of the soil. Continue rototilling until you loosen the soil in the planting area thoroughly.
Turn the rototiller off when you finish loosening the soil. Rake the soil smooth after you finish rototilling.
