Rooting Forsythia From Cuttings. Winter rooting can also be done with pencil sized cuttings if you do not have a high enough success rate with rooting this spring and summer. Forsythia are fun to propagate and you can easily grow several more plants from an existing mature hedge.
Forsythia can be propagate from soft wood cuttings. Moisten the perlite or sand and allow the pot to drain. Most gardeners prefer growing forsythia from cuttings rather than seed because forsythia seed is much harder to work with.
