Planting & Care for Trees - Hawthorn Trees

Preparation

  • Hawthorn trees are a delight to have in the landscape because of their attractive shape, shade potential, and clusters of pink or white flowers that bloom in spring.
  • Songbirds love hawthorns, too, and they’ll visit often in fall and winter to enjoy the bright-colored berries.
  • These trees are the perfect size for urban gardens due to their small scale.
  • Hawthorn trees need full sun and well-drained soil. They tolerate almost any type of soil and variations in pH.
  • Set the trees out in spring so they’ll have a full season to become established before winter.
  • In large settings they look great in groups, and they are pretty enough to stand alone as specimens in small gardens.
  • Although they make great lawn and street trees, avoid planting thorny varieties where children play or where pedestrians pass. The thorns are fierce, and can be as much as three inches long.

Opening Plant Material

  • Grow Bags - Remove bag by using a utility knife to slit up the side and peel off the fabric exposing the soil and roots. Plant the root ball just like you would a container plant. No trimming of roots is necessary for grow bags.
  • B&B - Soak root ball very well.
  • Containers - Completely saturate all container plants by putting in a larger container of water until stops bubbling, remove. Now you’re ready to plant.
  • 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 Grow Bags

  • Plant grow bags in spring or fall.
  • 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 the hole with soil, making sure the top of the root ball is visible and slightly higher than the soil around it.
  • Firm the soil around the plant. Water well to settle soil around the root ball.

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.

Planting containers

  • Slide plant from pot by tapping on the bottom of the pot.
  • Dig a hole no deeper than the depth of the container and 6" or more, making sure it’s wider on the sides
  • With shovel or knife trim bottom 2" off of the root ball for plants in plastic containers.
  • Rotate the plant to the proper position. Never lift or move plants by the tops.
  • Place the root ball in the hole.
  • 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 the hole with soil, making sure the top of the root ball is visible and slightly higher than the soil around it.
  • Firm the soil around the plant. Water well to settle soil around the root ball.

Pruning - After Planting

  • B&B & Grow Bags & containers - Although it is not essential for B&B, grow bags or containers 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

  • Hawthorn trees need little pruning. Remove suckers that arise from the base of the trunk. You can trim the canopy, if necessary, to keep it looking neat. Make cuts just beyond a lateral twig or bud that faces the direction in which you want the branch to grow.

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.
