Sumac Trees To Grow – Your Essential Guide For Edible And Ornamental

ByEric James Updated on

Dreaming of a backyard that’s both beautiful and functional? Perhaps you’re looking to add a unique, edible element to your homestead or simply want a striking native plant for your landscape. Sumac, often misunderstood, offers a surprising array of benefits and varieties perfect for outdoor enthusiasts.

This guide will walk you through the exciting world of sumac trees to grow, demystifying their cultivation and highlighting their versatility. From vibrant fall colors to tart, vitamin-C-rich berries, discover how sumac can enhance your outdoor living and self-sufficiency.

Understanding the Diverse World of Sumac

When you think of sumac, you might picture the wild varieties you’ve encountered on hikes. However, there’s a whole family of these shrubs and small trees, many of which are excellent choices for intentional cultivation. Understanding the different types is the first step in choosing the right sumac trees to grow for your needs.

These woody plants belong to the genus Rhus and are known for their compound leaves, often turning brilliant shades of red, orange, and yellow in autumn. Many species produce fuzzy, crimson fruit clusters, famously used to make a lemonade-like beverage.

Staghorn Sumac: The Iconic Edible Choice

Rhus typhina, commonly known as Staghorn Sumac, is perhaps the most recognizable and popular for edible uses. Its velvety, antler-like branches in winter give it its name.

It’s a fast-growing, adaptable shrub that can spread via root suckers, making it a good choice for naturalizing an area or creating a dense screen. The tart berries are a fantastic natural source of vitamin C.

Smooth Sumac: A More Compact Relative

Rhus glabra, or Smooth Sumac, is similar to Staghorn Sumac but lacks the fuzzy branches, hence its name. It also produces edible berries and offers stunning fall foliage.

This species tends to be a bit more upright and less aggressive in its spreading habit than Staghorn Sumac, making it a tidier option for some landscapes. It’s equally valuable for its culinary and ornamental contributions.

Fragrant Sumac: Aromatic and Drought-Tolerant

Rhus aromatica, often called Fragrant Sumac, is a low-growing, spreading shrub that’s prized for its aromatic foliage. When crushed, the leaves release a pleasant, lemony scent.

This variety is exceptionally drought-tolerant once established and is excellent for erosion control on slopes. While its berries are edible, they are typically less abundant and tart than those of Staghorn or Smooth Sumac.

Poison Sumac: A Crucial Distinction

It is absolutely vital to distinguish edible sumac varieties from Toxicodendron vernix, commonly known as Poison Sumac. This plant grows in wet, swampy areas and has smooth, white berries and glossy leaves with smooth edges. Never attempt to harvest or grow Poison Sumac. Contact with any part of this plant can cause a severe, itchy rash. Always positively identify your sumac before considering any interaction.

Cultivating Your Sumac Trees to Grow: Site Selection and Soil

Choosing the right location is paramount for successful sumac cultivation. These plants are remarkably forgiving, but a little planning goes a long way.

Sumacs generally prefer full sun to partial shade. More sun typically leads to better berry production and more vibrant fall color. They are not overly fussy about soil type, tolerating poor, rocky, or sandy conditions.

However, they thrive best in well-drained soil. Avoid areas where water consistently stands, as this can lead to root rot, especially for species other than Poison Sumac.

Soil Preparation for Optimal Growth

While sumacs are tough, a little soil preparation will give them a strong start. Loosen the soil in the planting area to a depth of about 12-18 inches. If your soil is heavy clay, consider amending it with compost or well-rotted manure to improve drainage and fertility.

For native plantings or naturalized areas, minimal soil amendment is often best to encourage a robust, self-sufficient plant.

Planting Your Sumac: Step-by-Step

Planting sumac is a straightforward process, whether you’re working with bare-root specimens or potted plants. Timing is important; aim for early spring or fall when the plant is dormant.

For Potted Sumac:

  1. Dig the Hole: Dig a hole that is twice as wide and as deep as the plant’s root ball.
  2. Prepare the Roots: Gently remove the sumac from its container. If the roots are tightly bound (root-bound), carefully loosen them with your fingers or a small trowel.
  3. Place the Plant: Position the sumac in the center of the hole so that the top of the root ball is level with the surrounding soil.
  4. Backfill and Water: Fill the hole with the excavated soil, gently firming it around the base of the plant. Water thoroughly to settle the soil and eliminate air pockets.

For Bare-Root Sumac:

  1. Dig a Wider Hole: Dig a hole that is wide enough to spread the roots out naturally. Create a small mound of soil at the bottom of the hole.
  2. Soak the Roots: Soak the bare roots in water for a few hours before planting.
  3. Position the Plant: Place the sumac on the mound, spreading the roots over it. Ensure the crown (where the roots meet the stem) is at or slightly above soil level.
  4. Backfill and Water: Fill the hole with soil, gently firming as you go. Water deeply to help the soil settle around the roots.

Watering and Mulching Needs

Newly planted sumacs will require regular watering to establish their root systems. Keep the soil consistently moist but not waterlogged. Once established, most sumac varieties are quite drought-tolerant.

A layer of organic mulch, such as wood chips or shredded bark, around the base of the plant is beneficial. Mulch helps retain soil moisture, suppress weeds, and regulate soil temperature. Keep the mulch a few inches away from the main stem to prevent rot.

Pruning for Health and Aesthetics

Sumacs generally require minimal pruning. However, occasional pruning can help maintain shape, remove dead or damaged branches, and manage suckering.

Managing Suckers

Many sumac varieties, particularly Staghorn and Smooth Sumac, spread by root suckers. If you want to keep the plant contained or prevent it from spreading into unwanted areas, you’ll need to manage these suckers.

You can do this by regularly digging them up and transplanting them elsewhere, or by simply cutting them back at ground level. For a more naturalized look, allow some suckers to grow, which will eventually form dense thickets.

General Pruning

Prune dead, diseased, or crossing branches anytime. For shaping or rejuvenation, heavy pruning can be done in late winter or early spring before new growth begins. This is also a good time to prune for berry production, as fruits form on the previous year’s growth.

Harvesting and Using Sumac Berries

The true magic of many sumac trees to grow lies in their vibrant red fruit clusters, known as drupes. These berries are a powerhouse of flavor and nutrients.

When to Harvest

The berries are typically ready for harvest in late summer to early fall, just as they begin to ripen and deepen in color. They should be a bright, ruby red. You’ll know they’re ready when they feel slightly soft to the touch.

How to Harvest

Using clean pruning shears or scissors, carefully cut off the entire berry cluster. It’s best to harvest on a dry day. Wear gloves if you have sensitive skin, as some individuals can experience mild irritation from the fine hairs on the drupes.

Preparing Sumac Lemonade (A Quick Example)

The most common use for sumac berries is to make a refreshing beverage.

  1. Rinse: Gently rinse the berry clusters under cool water to remove any dust or insects.
  2. Infuse: Place the rinsed clusters in a pitcher or bowl. Cover them with cold water.
  3. Steep: Let the berries steep for several hours, or even overnight, in the refrigerator. The water will turn a beautiful pinkish-red and develop a tart, lemony flavor.
  4. Strain: Strain the infused water through a fine-mesh sieve or cheesecloth to remove the berries and any fine hairs.
  5. Sweeten: Sweeten to taste with honey, agave, or sugar. Serve chilled over ice.

Other Culinary Uses

Beyond lemonade, sumac berries can be dried and ground into a powder used as a spice. This tangy powder is a staple in Middle Eastern cuisine, often sprinkled on meats, salads, and dips like hummus. Experiment with it as a seasoning for fish or poultry.

Propagating Your Sumac

If you’re interested in expanding your collection or sharing with friends, propagating sumac is a rewarding process.

From Seed

Starting sumac from seed is possible, but it can be a slow process. Seeds require a period of cold stratification (exposure to cold temperatures) to break dormancy. Sow seeds in a well-draining mix in the fall and leave them outdoors over winter. Germination typically occurs in spring.

From Cuttings

Taking stem cuttings in late spring or early summer is a more reliable method for many sumac species.

  1. Select healthy, semi-hardwood stems.
  2. Cut sections about 4-6 inches long, just below a leaf node.
  3. Remove the lower leaves.
  4. Dip the cut end in rooting hormone.
  5. Insert the cuttings into a moist, well-draining potting mix.
  6. Keep them in a warm, humid location, and they should root within a few weeks.

From Suckers

As mentioned, sumacs readily produce root suckers. These can be carefully dug up and transplanted. Look for suckers that have their own root system attached. Dig around the sucker, ensuring you capture as many roots as possible, and transplant immediately into a prepared spot.

Troubleshooting Common Issues

While sumacs are generally hardy, a few issues can arise.

Pests

Sumacs are relatively pest-resistant. Occasionally, aphids or scale insects might appear. A strong blast of water from a hose can often dislodge aphids. For more persistent infestations, insecticidal soap or neem oil can be effective.

Diseases

Root rot can occur in poorly drained soils. Ensure your planting site has good drainage to prevent this. Fungal leaf spots are rare but can be managed by improving air circulation through pruning and avoiding overhead watering.

Yellowing Leaves

If your sumac’s leaves are turning yellow, it could be due to overwatering, underwatering, or a nutrient deficiency. Check your watering schedule and soil drainage. If the plant is otherwise healthy, a light feeding with a balanced, slow-release fertilizer in spring might help.

Supporting Wildlife

The berries provide a vital food source for birds, deer, and other small mammals, especially during winter. The dense growth habit offers shelter and nesting sites for various creatures.

Erosion Control

With their extensive root systems, sumacs are excellent for stabilizing soil on slopes and preventing erosion, making them a practical choice for uneven terrain around campsites or rural properties.

Natural Landscaping

Their vibrant fall colors and unique forms make sumacs a stunning addition to naturalized gardens, borders, or as specimen plants. They require little maintenance once established, fitting perfectly into a low-effort, high-reward landscaping approach.
