marcottage
/mɑːkɒˈtɑːʒ/ /ˈmɑːkɒtɪdʒ/ /mɑːˈkɒtɪdʒ/Horticulture
noun
A method of propagation of woody plants in which a wound made in the bark of a shoot is covered with a layer of rooting medium and wrapped to retain moisture, encouraging new roots to form before the shoot is severed from the parent plant.
Origin
1920s. From French marcottage propagation by layering from marcotter from marcotte + -age. Middle French marquot, originally denoting a vine shoot used for layering, is from classical Latin marcus type of vine (said by Columella to be of Gaulish origin) + -ot.
