Details

This ground cover sumac is the western version of the Gro-Low sumac we have in the Midwest. Rhus trilobata is a three leaved sumac native from New Mexico to Canada. This selection will get about a foot tall where planted, but the branches will spread out in all directions up to 5-6 feet across with runners that lay flat on the ground. The fall color is mainly golden yellow. An excellent xeriscape plant, good for embankment plantings. Mature size is around 12" tall x 5-6' wide.

Planting & Care for Deciduous Shrub – Sumac

Preparation

  • A flatter version of gro-low sumac known for its very low, wide-spreading habit.
  • This has excellent glossy foliage and slight yellow color in fall.
  • Great plant for mass planting and bank control in your garden.
  • You're going to want to prune this shrub heavily in early spring when necessary.
  • Xeriscape plant.
  • This shrub matures to be around 1' tall x 5-6' wide.
  • This is treasured for its interesting texture and form in the landscape.

Opening Plant Material

  • Bare Root - Cut open the bundle (top and roots are tied) and separate all the plants. Soak roots in buckets of water until planted. Each plant type will be labeled separately for identification. Do not expose the roots to sun. They should never dry out. Keep roots covered. All bare-root plants must be trimmed when planted. 
  • Containers - Completely saturate all container plants by putting in a larger container of water until stops bubbling, remove. Now ready to plant. Dig a hole no deeper than the depth of the container and 6" or more, making sure it’s wider on the sides.

Planting Bare Root

  • Plant Bare root in 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 the same depth as the root mass. The crown or graft of the plant should be slightly higher than ground level where it was grown at the nursery.
  • Trim off the broken roots and branches.
  • Place fertilizer packets in hole (if purchased). Do not place other fertilizers in the planting hole. *Use Our Recommended Fertilizer.
  • Spread the roots and fill halfway with soil, then water until soil settles completely saturating the soil and planting pit.
  • Re-adjust plant and fill the hole with the rest of the soil.
  • Back fill the balance of the soil and water well. 
  • See our link below “Handling & Planting Guidelines” for illustrations on planting.   

Planting containers

  • Plant in March, May – November.
  • Slide plant from pot by tapping on the bottom of the pot.
  • 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

  • Bare Root - Prune ALL bare root plants to reduce transplant shock and ensure success. Pruning should occur either before or as soon after planting as possible. All pruning should be done with a sharp pruning shears.
  • Containers - Although it is not essential for contianers 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

  • When pruning in late winter or early spring, remove any branches that grow beyond the desired shape and height of the shrub.
  • Use sharp shears and make clean cuts straight across each branch.
  • You can also thin out branches from the center of the shrub for a more open growth habit, if desired.

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.
