The Sacred Heart of Jesus Catholic Church Youth Group spent a recent Saturday morning removing privet, an invasive species, from the Hart County Botanical Garden. Their effort was part of a community service challenge. Shown with the group are their leader, Shannon Jones (L), youth education coordinator and garden curator, Jeannie Brownsberger (R-rear) and garden curator Vickie Peace (R-front.)

How to Plant a Tree or Shrub
When you plant a tree, you celebrate the earth by increasing its leafy canopy. According to the U.S. Department of Agriculture, "One acre of forest absorbs six tons of carbon dioxide and puts out four tons of oxygen. This is enough to meet the annual needs of 18 people." Trees also add beauty, increase the value of your home, provide cooling shade and offer shelter for wildlife. Proper planting is critical to their survival and long-term success. Digging the HolePlanting too deep is the top reason that trees and shrubs die. Follow these simple steps to ensure the correct planting depth for both balled-and-burlapped (B&B) and potted trees.
Locate the point at which the trunk flares out to join the roots. On B&B trees, remove the twine and burlap at the base of the trunk. If necessary, gently push the soil away from the base of the trunk to find the flare.
Measure the distance from the bottom of the root mass to the trunk flare. Dig the hole no deeper than this; you want the root mass to sit on undisturbed soil. When planting is complete, the trunk flare should be slightly above the existing soil grade.
Dig the hole two to three times the diameter of the root ball or container, sloping the sides gently outward to the existing soil grade.
BackfillThe thinking on backfill has changed in recent years. Although it was once common to modify the backfill soil with amendments — such as compost, peat moss, aged manure and other ingredients — it is now considered best practice to leave the backfill unaltered or add minimal amendments. This encourages roots to spread out into the native soil, rather than staying within the confines of the planting hole. We do recommend adding mycorrhizal fungi and bone meal to the backfill. Mycorrhizal fungi form associations with plant roots and help them extract and absorb minerals and water from the soil. Trees and shrubs with mycorrhizal-enhanced root systems adapt better and are more tolerant of stressful environments. Bone meal provides essential minerals that promote sturdy root systems and stimulate plant growth. PlantingWhen moving your plant into the planting hole, disturb the rootball as little as possible. Lift B&B trees and shrubs by using the rope, burlap or wire cage on the rootball. Lift potted plants by grasping the container. Don't lift plants by the trunk, stems or branches. Don't allow the root system to dry out before or during planting. B&B trees and shrubs
Place the tree in the center of the hole. If necessary, straighten or stabilize the tree by adjusting or filling beneath the root ball with the backfill mix.
Cut away any twine or burlap from the base of the trunk and remove any burlap that is on the top of the rootball. Remove excess soil from the top of the rootball to expose the trunk flare, if needed.
Use bolt cutters to remove as much of the wire basket as possible. Don't try to remove the entire wire basket. The plant will thrive even if there is some of the basket left in the hole. Remove all the rope and twine from the rootball, as well as any nails holding the burlap together. Pull back the burlap and cut away any loose material. It's OK to leave some burlap in the hole to decompose. However, remove all plastic or treated burlap.
Potted trees and shrubs
Tip the container on its side and slide the plant from the container. Place the plant in the hole by lifting the root mass, not the plant itself. If the plant has become pot-bound, it may be necessary to cut the container before the plant can be removed.
To encourage root growth, tease the outer roots from the soil. If the roots are tightly matted, use a knife to score the root mass in several places and gently loosen the root ball. This won't harm the plant and will encourage new root growth.
Backfilling and watering the planting hole
Add backfill soil to your planting hole until it comes about halfway up the root ball. Use your foot or hands to firm the soil and eliminate air pockets. Make sure the trunk is vertical and confirm that the trunk flare will sit slight above soil grade once backfilling is complete. Continue adding backfill and packing it down until you've reached the top of the root ball, taking care not to cover the trunk flare.
Construct a 3–4" high ridge of soil around the outer edge of the planting hole. This berm will create a basin to hold irrigation water and concentrate it over the roots. Use a hose to fill the basin, then allow the water to soak it, repeating several times. Or, let the water run at a trickle for 15 to 30 minutes to ensure that the entire root zone is moist. The goal is to ensure even watering so the soil is drenched and any large air pockets are eliminated.
Recheck that the trunk flare is completely exposed and the top of the root ball has not been covered with additional soil. Remove any plant tags or labels from the tree.
MulchingApply bark mulch or pine straw to a depth of 2–3" over the entire planting hole. Mulching helps conserve water and prevent weeds. Taper the mulch toward the base of the tree, but do not allow it to touch the tree trunk. StakingStaking at planting time is not always necessary. Consider the stability of the rootball, trunk size and strength, direction of prevailing winds, canopy size and density when determining whether or not to stake. If in doubt, ask a nursery professional. FertilizingWe do not recommend fertilizing newly planted trees and shrubs during their first year of growth. WateringProper moisture is critical to the survival of your young tree or shrub. The roots should never dry out completely, nor should they be waterlogged. The best way to check soil moisture? Use your finger. Dig down 2–4" just outside the root mass of the plant and water if the soil feels dry. Newly planted shrubs and trees should be checked and watered every other day for the first two weeks. After the first two weeks, limit watering to once a week if less than 1" of rain falls during the week. Thorough soakings that moisten the soil to the entire depth of the root mass are better than frequent light waterings.

Plant species have varying water requirements. Before watering according to the chart, use your finger to check actual soil moisture and get familiar with the moisture requirements of your plants. Plant SizeAmount of Water per Application Small shrub4-5 gal. Large shrub7-10 gal. Small trees (<2" caliper)7-10 gal. Large trees (>2" caliper)10–20 gallonsWater measurements can be made using an old 1-gallon plastic milk container. When using a hose, turn on the water at a slow trickle and take note of the setting. Count the amount of time it takes to fill the 1-gallon container. Multiply that amount of time by the number of gallons you need for your plant. That total provides the amount of time you need to run the hose, based on the chart.
Gardens are open dawn to dusk daily, free of charge. Please keep dogs leashed.

The majority of the planning and work completed at the garden is done by volunteers. We also provide educational opportunities for the community, often in conjunction with the Master gardener program. The garden is financially self-supporting. We raise funds to improve the garden by holding an annual plant sale, collecting membership fees, through the sale of commemorative trees and bricks, and other community events. The garden continues to improve as funds and volunteers are available.
