How to propagate a branch from Forsythia?

The best time to take cuttings is from early spring to mid-summer. Dip the 2- to 3-inch-long cut section in rooting hormone and allow it to scab over before pressing into a pot containing a moist seed-starting medium. Water the cutting in about three weeks.

Propagating Forsythia

Forsythia are fun to propagate, and you can easily grow several more plants from an existing mature hedge.

The best time to propagate forsenthia is June and July, when the plant produces vigorous new shoots. Forsythia can be propagate from soft wood cuttings. Look for a new flush of growth among the branches, and choose your cuttings carefully, seeking healthy, vigorous branches.

Clean your pruning shears with alcohol and take several cuttings from among this new growth. Each branch should be at least four to six inches long. Strip off the leaves or pick off the leaves on the lower half of the cutting. Dip the end into rooting hormone, then place the end with the rooting hormone into a pot of rooting medium. You can also use perlite. Several cuttings can be rooted at once in a flat or tray, or use small pots for your propagation experiment.

After inserting the cut end into the pot, firm the soil with your fingers and water it well. Use a clear plastic bag, such as a bag from the produce department of the supermarket, to cover the top of the tray or pot like a dome. This creates a sort of miniature greenhouse to keep the cuttings moist and the humidity high.

Place the covered forsythia cuttings in a bright, sunny spot, but not in direct sunlight. Within six to eight weeks, the cuttings should root, and you’ll see new leaves begin to emerge. At this stage, transfer them to larger containers with sterile potting soil, and continue to nurture them along. Plant them in the fall so that they get a head start on root development for the following spring.

The method above is beautifully detailed.

Additionally -We were also taught in Propagation class to take the pruners sharp edge and slightly rough up or strip away some the outer woody bark BEFORE dipping in the rooting hormone powder.

Often have good luck with just cutting a branch, skinning some of the bark off with a knife and pushing it in the soil where you want it. Most will grow like that on their own.
