| From Uncommon Fruits for Every Garden (again): Grafting
has not been a very satisfactory method of juneberry propagation. Grafts often
take on rootstocks of other genera, such as mountain ash, hawthorn, and other
members of the rose family, but the grafted plants sometimes stop growing.
Stocks generally used have included Cotoneaster acutifolius, C.
bullatus, Sorbus intermedia, and S. aucuparia. Amelanchier
alnifolia is apparently the juneberry most compatible with other genera.
Plant juneberries grafted onto other genera low enough in the ground to allow
the juneberry scion to root. The rootstock, in this case, acts as a temporary
nurse root, but may have the unfortunate habit of continually sending up
sprouts. Crataegus arnoldiana as a juneberry rootstock reputedly shuns
this bad habit. Interestingly,
one Amelanchier species is not always graft compatible with another.
When grafting a juneberry scion onto juneberry roots, choose a nonsuckering
clone for roots or you will constantly be finding shoots thrown up from the
rootstock. Lee Reich, PhD Books by Lee Reich: A Northeast Gardener's Year The Pruning Book Weedless Gardening Uncommon Fruits for Every Garden Landscaping with Fruit On Nov 6, 2009, at 12:48 PM, Kieran &/or Donna wrote:
