Selecting Elm and Zelkova Cultivars for Kansas Zone 6a Landscapes

Three Excellent Tree Choices for South Central Kansas

All three selections—'Emerald Sunshine' elm (Ulmus propinqua), 'Allee' elm (Ulmus parvifolia), and 'Wireless' zelkova (Zelkova serrata)—are fully hardy to Zone 5, making them well-suited for your Zone 6a location in Kingman. Their proven wind tolerance also matches plains conditions.

Cultivar Highlights

• 'Emerald Sunshine' elm: Vase-shaped, glossy foliage, excellent heat/drought tolerance, resistant to Dutch elm disease and elm leaf beetle.
• 'Allee' elm: Exfoliating bark, upright arching form, superior pest resistance, tolerant of urban soils.
• 'Wireless' zelkova: Low, spreading habit (24' tall × 36' wide), no seeds, stunning red fall color, ideal under power lines.

Optimal Planting Time and Technique

Plant in early spring (after frost, before leaf expansion) for best establishment. Fall planting is acceptable but carries higher risk in your region.

1. Dig hole twice the root ball width and equal depth.
2. Remove all burlap, wire, and twine from root ball.
3. Backfill with native soil amended with quality topsoil/compost.
4. Apply 2-3 inches organic mulch—keep away from trunk.
5. Water thoroughly at planting and weekly thereafter (1 inch per week).

First-Year Care

No fertilizer needed initially. Monitor soil moisture, especially during summer heat. Stake only if necessary, and remove stakes after one growing season.
