\"Clematite_1\"<\/a> Ma belle cl\u00e9matite "Dr Ruppel"<\/a> est malade! Voil\u00e0 qu’en une journ\u00e9e les feuilles d’une de ses tiges se sont brusquement fan\u00e9es. C’est un ph\u00e9nom\u00e8ne courant en cette p\u00e9riode de l’ann\u00e9e o\u00f9 ces grimpantes<\/a> d\u00e9marrent leur floraison, fragilis\u00e9es par cet effort mais aussi par le temps chaud, elle a \u00e9t\u00e9 attaqu\u00e9e par un champignon qui lui fait des mis\u00e8res.<\/p>\n

Il s’agit du champignon "ascochyta clematidiae" qui se localise dans le sol et l’infecte, la s\u00e8ve circule mal ou plus du tout dans les vaisseaux et les tiges s\u00e8chent. Ce d\u00e9p\u00e9rissement<\/a> est fulgurant et on est toujours sid\u00e9r\u00e9 de voir sa cl\u00e9matite en forme un jour et quasi morte le lendemain!<\/p>\n

Il ne faut pas baisser les bras devant le probl\u00e8me. La premi\u00e8re chose \u00e0 faire est d’\u00f4ter la terre autour des tiges atteintes et de couper celles-ci sous le point contamin\u00e9. Ceci fait,enlevez quelques centim\u00e8tres de substrat et remplacez-le par un m\u00e9lange sain de terreau riche en humus et de sable. Assurez-vous que le pot o\u00f9 que le sol o\u00f9 se trouve la cl\u00e9matite est bien drain\u00e9, ces plantes  d\u00e9testent l’humidit\u00e9 stagnante. Enfin, traitez avec un fongicide ou avec de la bouillie bordelaise.
Pour \u00e9viter ce probl\u00e8me, il faut agir \u00e0 titre pr\u00e9ventif, pr\u00e9voir un bon lit de graviers pour avoir un bon drainage, bien coucher la motte au moment de la plantation et enterrer de ce fait la tige sur 15 cm. Ne l’arrosez pas trop.
N’oubliez pas que la cl\u00e9matite doit avoir le pied \u00e0 l’ombre et la t\u00eate au soleil, plantez une vivace \u00e0 son pied, c’est efficace.<\/p>\n","protected":false},"excerpt":{"rendered":"
