Planting & Care for Trees – Oak

Preparation

  • When planting other plants around oak trees, you should select only drought-tolerant plants that don't require summer watering.
  • It's best to space them at least 6 feet from the base of each oak tree, to give the oaks breathing room.
  • It's also appropriate to lay 2 to 3 inches of mulch around the base of each oak tree to keep the soil from drying out and prevent weeds from growing.
  • Oak trees prefer full sun and well-drained soil.

Opening Plant Material

  • B&B - Soak root ball very well.
  • Each type of plant has an illustration on how to plant if you scroll down and click on the orange rectangular box “Handling & Plant Guidelines”.

Planting B&B trees

  • Plant B&B trees in spring or fall. A good indicator if you can still plant is if the ground is still workable you’re good to go. If a hard frost is expected be sure to hold off on planting.
  • Dig a hole at least 6" wider and no deeper than the size of the ball on the plant. Rotate the plant to the proper position. Never lift or move trees by the tops.
  • Notice where the base of the trunk flairs out from the tree. This is called the root flair. This root flair should show when the tree is planted. If necessary, add soil under the ball so the root flair is exposed.
  • Place fertilizer packets into the bottom of the hole (if purchased). *Use Our Recommended Fertilizer
  • Backfill ½ of the hole with soil and completely saturate the soil with water.
  • Once the tree is straight and located as desired, cut and remove twine. Then, remove or bend back top ⅓ of metal basket. Lastly, remove exposed burlap from top of ball
  • Fill the hole to the top of the ball with soil, then soak well with water and let settle.
  • The top of the root ball should be visible and slightly higher than the soil around it.
  • Add mulch on top of soil making sure to not put mulch against the trunk or stems.
  • See our link below “Handling & Planting Guidelines” for illustrations on planting.

Pruning - After Planting

  • B&B - Although it is not essential for B&B to be pruned after planting, a light pruning for shape, to remove any broken branches from shipping, or to thin out a heavily branched plant will help in the transplanting process and in the appearance of your new planting.

Pruning - Through-out the Season

  • Be sure not to prune April-October. This is when small beetles can transmit oak wilt, a fungal disease that discolors the leaves and eventually kills oaks.
  • Deciduous oak trees need regular pruning; evergreen oaks prefer to grow without it.
  • The safest time to prune them is during the dormant period in winter, as this sparks new growth for the blooming season and allows wounds to heal as warm spring weather hits.

Watering - After Planting

  • Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as often as every 2-4 days at the start and at least a minimum of once per week.
  • Beyond the 6 week establishment period, water once per week, unless rains occur.
  • Stick your finger into the soil around 3” to check soil moisture.

Watering - Through-out the Season

  • After the first season, plants should only be watered during extended periods without rain.
  • How do you know if your plants need water? The easiest way to tell is to touch the soil around the roots. If it is moist, there is no need to water. If it is dry, give it a good soaking with the hose end (no nozzle) watering the soil only, not the leaves.
  • Stick your finger into the soil around 3” to check soil moisture.
