In many of the trials, root and/or shoot growth was stimulated by the addition of fertilizer but in almost all cases, the cuttings also had to be treated with a chemical root-inducing compound for the effects to be noticeable.

A series of experiments was conducted with cuttings of several species of woody ornamental plants to determine the effect of fertilizer applications during the rooting period on the rooting, root growth and shoot growth of the cuttings.

It was found that soaking greenwood cuttings of California Privet (Ligustrum ovalifolium) for 24 hours in a liquid fertilizer had no effect on rooting or root growth and a very slight effect on shoot growth. After the cuttings were inserted in the rooting medium
