Dans la culture des plantes succulentes ou à caudex difficiles, il apparait, depuis quelques années, que la Pierre ponce constitue un élément des plus précieux permettant de maintenir en vie des variétés qui, jusqu'à présent, étaient impossible à conserver. La pierre ponce ou Pumice, n'est peut-être pas la panacée mais on ne peut plus la négliger dans nos cultures. Par rapport à la pouzzolane, également d'origine volcanique, la ponce a un avantage indéniable : en hiver, quand les conditions deviennent défavorables aux arrosages excessifs, elle se dessèchera beaucoup plus rapidement permettant d'avoir un substrat toujours bien aéré, alors que la pouzzolane risquera de rester plus longuement humide...Nous l'utilisons dans pratiquement tous nos mélanges.

On peut l'employer de différentes façons :

* pure pour la reprise de végétaux que l'on vient de recevoir et qui auront voyagé à racines nues

* mélangée avec du terreaux, quand les végétaux ont repris et pour les espèces qui ne supportent pas la ponce pure (il y en a certaines)

* finement tamisée pour les semis, en totalité,en surfaçage.

Nous la commercialisons en sachet de 4 litres de granulométrie 5 à 8 mm non lavée. Idéale pour le drainage et pour les plantes aux grosses racines
