La m\u00e9thode en bref<\/h2>\n\n\n
\"S\u00e9lectionnez
S\u00e9lectionnez du mat\u00e9riel sain et \u00e9tiquetez chaque essai. Utilisez un substrat a\u00e9r\u00e9 et les conditions d\u00e9crites ci-dessous. V\u00e9rifiez la pr\u00e9sence de racines et notez le r\u00e9sultat avant de rempoter. Les r\u00e9sultats varient ; l\u2019illustration ne garantit pas l\u2019enracinement. Illustration de la m\u00e9thode g\u00e9n\u00e9rale ; les conseils propres \u00e0 la plante ci-dessous priment.<\/figcaption><\/figure>\n\n\n

Avant de commencer<\/h2>\n\n\n

Utilisez le mat\u00e9riel sain et ferme le plus jeune disponible. S\u00e9parez et \u00e9tiquetez chaque bouture. Pour les tiges m\u00fbres ou dormantes exp\u00e9di\u00e9es, une m\u00e9thode destin\u00e9e aux extr\u00e9mit\u00e9s feuill\u00e9es peut \u00eatre inadapt\u00e9e.<\/p>\n\n\n

Pr\u00e9parez un pot \u00e9tiquet\u00e9 et perc\u00e9, des ciseaux propres et du substrat neuf pour boutures. D\u00e9ballez la bouture \u00e0 r\u00e9ception et v\u00e9rifiez que la tige est ferme et saine.<\/p>\n\n\n

Conseils propres \u00e0 cette plante<\/h2>\n\n\n

Essayez de jeunes pousses non fleuries au chaud. Le semis est g\u00e9n\u00e9ralement plus pratique pour reproduire l\u2019esp\u00e8ce. Portez des gants pr\u00e8s des aiguillons.<\/p>\n\n\n

Essayez des pousses juv\u00e9niles sous humidit\u00e9 prot\u00e9g\u00e9e. Les boutures de tiges m\u00fbres donnent des r\u00e9sultats incertains. Portez des gants contre les \u00e9pines et envisagez le semis pour reproduire l\u2019esp\u00e8ce.<\/h2>\n\n\n

Essayez une ou deux extr\u00e9mit\u00e9s feuill\u00e9es saines dans un substrat a\u00e9r\u00e9 et humide, en lumi\u00e8re filtr\u00e9e et sous une protection humide ventil\u00e9e. A\u00e9rez la base et retirez rapidement les boutures d\u00e9p\u00e9rissantes. Si le mat\u00e9riel est pr\u00e9cieux ou rare, consultez d\u2019abord une p\u00e9pini\u00e8re sp\u00e9cialis\u00e9e en multiplication.<\/p>\n\n\n

Quand rempoter<\/h2>\n\n\n

Attendez-vous \u00e0 des r\u00e9sultats variables. Notez la maturit\u00e9 des boutures et les conditions de culture. V\u00e9rifiez les racines avant de rempoter et utilisez l\u2019alternative ci-dessous si l\u2019enracinement se r\u00e9v\u00e8le peu fiable.<\/p>\n\n\n

En cas de probl\u00e8me<\/h2>\n\n\n

Le fl\u00e9trissement peut venir d\u2019un exc\u00e8s de chaleur, d\u2019un manque d\u2019eau ou d\u2019une base pourrie. Placez la bouture en lumi\u00e8re diffuse, v\u00e9rifiez la tige et ajustez l\u2019humidit\u00e9 ou le drainage avant d\u2019arroser davantage. \u00c9liminez les parties moisies ou affaiss\u00e9es.<\/p>\n\n\n
