Question
Thank you for taking the time to answer my question.
I have picked out three trees that I would like to plant in my back yard in Kingman, which is located in South Central Kansas (planting zone 6a.)  I would like to know if these three trees will grow well in my area.  Here they are:

Emerald Sunshine Elm, ulmus propinqua 'JFS-Bieberich'

Allee Elm, ulmus parvifolia 'Emer II' PP7552

Wireless Zelkovia, zelkovia serrata 'Schmidtlow'

Thank you for your time.  I look forward to your answer.

Sincerely,
Tim

You should not have any problem as far as weather related in growing any of these three trees in your location. They are all grown in Zone 5. Hardiness zones are related to the low temperature and since you are south of zone 5 the low temperatures will not be a factor. All these trees also work well in winds of the plains. I would however wait and plant these in the spring--the best time for hardwood trees. Deciduous trees and shrubs may be planted either in the spring or the fall. Deciduous plants may be planted in the spring as soon as the frost is out of the ground, up until the time when new foliage is partly unfurled. You can plant late Fall but the early spring would be the best time.

Dog the new hole twice the size of the rootball and as deep and set the rootball so the top of the ball is at ground level. Remove the burlap and wire from the roots and fill with good top soil or potting soil. Mulch around the trees with not more than 3 inches deep of organic mulch not piled up on the trunk. This will help hold moisture around the roots.
