A substance affecting plant meristems (which comprises 5:5'-dichloro- 2:2'-dihydroxy-phenylmethane, or a derivative or salt thereof) is used to impregnate the material intended to form a wall, bottom and/or support of a container designed to hold plants, preferably forest tree plants, during the nursing period thereof. Said impregnating substance temporarily holds back the development of the plant roots by affecting the meristems thereof, and is used in a minimum amount of 0.5 g/m<2> for a surface weight of the material of at least 50 g/m<2>. |
