necessary energy needed for root development. While removing
leaves reduces the surface area for water loss, pruning the bottom leaves that touch the rooting substrate is sufficient.
Also, depending on the plant, wounding the cuttings might be
needed to induce root formation. This is often necessary with
hard to root plants like rhododendron, magnolia and pinus. To
wound, use a clean sharp knife or pruners to scrap away the
outer layer (1 to 2 in.) to expose the inner green layer. Make

“It is also preferable to mist the
cuttings prior to sealing, but if
you do not have access to water
simply use a sealable bag.
