Title:
PROPAGATING THE NEW UNIVERSITY OF MINNESOTA HARDY DECIDUOUS AZALEAS1

Authors:
Rick Henny and Paul E. Read

pp: 331-339

Abstract:
Cuttings from selected clones of deciduous azaleas, specifically hybrids resulting from reciprocal crosses of Rhododendron × kosterianum2 × R. roseum, which are winter hardy in Minnesota, were successfully rooted with plastic-tent propagation. Rooting under mist was unsuccessful because of hard water and subsequent salt buildup on cuttings. Best rooting occurred in a 1:1 peat-vermiculite or a 1:1 peat-perlite medium, but no single rooting compound gave consistently superior results Succulent cuttings in the elongation stage of growth, having expanding leaves, and cuttings with fully expanded leaves but no terminal bud formation rooted well.
