Planting Instructions for Trees and Shrubs

Digging the Hole

  • Dig the hole approximately 2-3 times as wide as the soil ball.
  • Measure the height of the root ball. Dig the hole 1-2 inches.
  • When digging is complete, roughen up the sides of the hole. This will help roots grow into the soil.

Preparing the Plant

  • Remove the plastic container from the root ball. If the roots are growing in a circle, make 3-4 shallow cuts down through the roots and the soil ball.
  • Back fill the hole using the original soil dug from the hole. Poor soils may benefit from the addition of the Organic soil amendment, but you should never completely backfill with an amendment. If you use a soil amendment, mix it thoroughly with the original soil prior to backfilling the planting hole.

Fertilizing and Watering

  •  A slow-release, complete fertilizer that is high in phosphorus (the middle number) will aid in the development of a strong and healthy root system. The fertilizer should be mixed thoroughly with the original soil prior to backfilling. Never put directly on the roots of the plant.  
  • As you fill the hole, backfill evenly around the plant to keep air pockets to a minimum.
  • Once your planting hole is approximately three-quarters full of backfill, water the plant thoroughly to further eliminate air pockets in the backfill. Then completely fill the hole and water thoroughly once again.

After Planting

  • Never water automatically without checking the soil to determine if watering is needed. To do this, test the moisture of your soil about 4-8 inches deep. If it is dry or only slightly damp, the plant should be watered. Sandy soil generally will need to be watered more frequently then clay soil, but always check before automatically watering the plant.
  • Roots grow where oxygen and water are most available. Watering deeply and thoroughly and only as needed will encourage a deep and healthy root system that will be able to withstand environmental stresses.
  • A layer of mulch material such as bark or soil pep will help retain soil moisture and help prevent wide fluctuations in soil temperatures throughout the years. It will also inhabit the growth of weeds around the plant.
  • Just as you should not plant too deeply, neither should you mulch too deeply. Taper the mulch away from the stem. Do not pile mulch against the stem.
