Also known as: Celtis occidentalis North America · Common Hackberry
What's special about Common Hackberry North America
North American common hackberry; tough urban shade tree.
Growing this variety
Common Hackberry North America follows the same growing basics as Hackberry. Variety-specific maturity above; everything else below applies to the whole Hackberry family.
Germination
Spacing & depth
How to plant
Stratify seed as noted. Sow in deep pots filled with well-drained mix. Keep evenly moist and in bright light after germination. Hackberry seeds often have hard coats and benefit from scarification.
Pre-sow treatment
60–120 days cold moist stratification; scarify hard-coated seeds.
Grower's tip
Tough, adaptable shade trees with distinctive warty bark and small berry-like drupes loved by birds.
Soil preferences
Deep, well-drained native soil. Avoid amending the planting hole heavily — roots should learn to grow into the surrounding earth.
5.5–7.5 depending on species (conifers lean acidic; most hardwoods neutral).
Top-dress with compost and mulch in a wide ring; don't backfill with pure compost.
Watering
Deep soak weekly the first two years while roots establish; taper once the tree self-supports.
Slow trickle at the drip line, not the trunk. A 5-gal bucket with a pinhole is ideal.
Overwatered: yellowing, root rot, mushroom collar. Underwatered: leaf scorch, early leaf drop.
Prefers top-watering — Trees are always top-watered — deep slow soak at the drip line, never at the trunk. Bottom-watering only makes sense for nursery seedlings.
Temperature tolerance
Broad — most species tolerate 40–90°F once established
Down to species-rated USDA zone minimum
Hardy once established; young seedlings need protection their first winter.
Special germination requirements
Most temperate tree seed needs cold stratification (30–120+ days at 34–41°F) — see each species entry for the exact time.
Container growing
Possible with the right cultivar
Deep tree pots (root trainers) for the first 1–2 seasons; permanent site required for full growth.
Only dwarf, patio, or bonsai forms live long-term in containers.
Detailed harvesting
Not applicable for ornamental/timber trees. Nut and fruit species — pick when they drop naturally.
Post-harvest storage & preservation
Nuts: keep damp and cool, sow promptly. Winged/coned seed: dry, cool, dark in a sealed jar.
Culinary, medicinal & other uses
Shade, windbreak, wildlife habitat, timber, ornament, and long-term carbon storage.
Medicinal or traditional uses are shared for interest only — this is not medical advice. Consult a qualified professional before using any plant medicinally.
Seed saving
Wind- or insect-pollinated; seedlings rarely match the parent exactly (especially named cultivars — those must be grafted or cutting-grown).
Not practical for trees. Expect variation.
Collect fully ripe seed in fall, clean, dry or keep damp per species, then cold-stratify before spring sowing.

Common Hackberry North America Hackberry seeds on hand
Track packets and loose seeds you already have. Private to your account.
Par level — leave at 0 for no alert. Anything below par shows on Seed Starting and your shopping list.
From your kitchen — grow hackberry from what you already have
Trees usually mean patience — collect fully ripe seed in fall, clean pulp off, and give most species a cold winter (real or in the fridge) before they'll germinate.
- 1Collect ripe seed/nuts/cones in autumn from a healthy parent.
- 2Clean off any fleshy pulp; dry cones warm to release seed.
- 3Cold-stratify in a bag of damp sand or peat in the fridge (34–41°F) for the time listed on the species.
- 4Sow in deep tree pots and grow on 1–2 seasons before planting to a permanent spot.
Storage: Most tree seed keeps 1–3 years cool and dry; oak/hickory/chestnut nuts must stay damp and be sown promptly.
