How To Plant A Tree

Before You Plant

Site your tree

Consider the environmental conditions of your school site: sun, shade, slope, and soil moisture. These trees will do best in full to part-sun, and will help create new shade on campus. Remember – choose a water-loving species if the area stays moist or regularly floods. Choose a smaller tree if there are overhead wires.

Check for utilities.

If you’re planting in the front of your school, you’ll need to make sure there are no utility lines in your way. Call 811 five to seven days before digging. Once marked, make sure you plant at least 15’ from any marked lines.

Planting

Remove the pot

Gently lift your tree by the base of the trunk and lay it on the ground on its side. Be careful not to break off any branches. Remove the pot from the tree’s rootball – you may need to push on the sides of the pot to loosen the roots so it can be removed. Remove any tags, string, or stakes.

Prepare the roots

Once removed, gently massage and shake the soil from the roots. Use a similar motion as if you were washing your hair. Roots should be semi – exposed and not bound in a circle. (If roots are completely encircling the rootball and cannot be manually teased out, you may need to use a shovel or pruner to trim a few of them to release the roots.

Dig the hole

Now that you can see your rootball, dig your hole only as deep as the length between the trunk flare and the bottom of the rootball. Dig your hole two times as wide as the pot the tree came in. Your hole should be wider than it is deep. Tip – don’t toss the soil too far, you’ll need to return it to the hole shortly.

Check the depth

Place the tree in the hole to check the hole’s depth. The trunk flare should be even with the surrounding ground. If your hole is too deep, backfill soil and use your feet to tamp it down to a sturdy base for the tree to sit on.

Fill it in

Have one person hold the tree straight as you fill in the soil around the tree roots. Occasionally, tamp down the soil with your feet or hands. When filling the soil back in, separate out large grass chunks and to not place them in the hole. Fill in remaining soil until the ground around the tree is level and the trunk flare is still visible.

Mulch

Add a ring of shredded hardwood mulch (about 2 bags) around your tree in a circle like a donut. Leave the 3” around the trunk of the tree to prevent disease and rot. Mulch should be about 3” thick. This will reduce weeds and keep moisture in (which means less work for you later!).

Water

Turn your hose on low so that it does not splash back up when it hits the ground or cause a divot in the mulch. Water your tree around the base for 2 full minutes or until water starts to pool. Remember to water weekly for the first year.

Tips Specific to PGCPS

Water keys

If you selected a tree that will need watering, or you’re planting when the weather is warm, you’ll need to regularly water your tree for the first year. PGCPS schools have been built at different times and have different water spouts. You’ll need a water key to turn on the spouts. One of these should fit: 5/16” Silcock Key or 4-way Stem Key

Stakes

Wooden stakes inserted next to your tree can act as a visual deterrent when someone is mowing or working in the area. This can help protect your young tree.

Building Supervisor

Talk to your building supervisor or facilities team – they are experts on your campus! Let them know where you intend to plant because they may
