The addition of compost to the medium significantly
stimulated the rooting of geranium cuttings (Table 1).
Roots of the cuttings growing on the medium with the
addition of compost were 78% longer and their biomass
was 44% higher in comparison to the cutting roots from
the control medium. The addition of compost to the medium
increased the shoot biomass increment of rooted
cuttings, but had no effect on their length
