\"Rhododendron_rose\"<\/a> Les passionn\u00e9s de rhododendrons vous le diront, c’est une plante magnifique qui donne beaucoup de satisfactions mais dont il faut prendre soin. Ces vivaces \u00e0 port buissonnant ont une magnifique floraison qui selon les esp\u00e8ces s’\u00e9tale de la fin de l’hiver au d\u00e9but de l’\u00e9t\u00e9, leur feuillage \u00e9tant persistant et d’une belle couleur vert fonc\u00e9, m\u00eame en hiver les rhododendrons<\/a> restent d\u00e9coratifs.<\/p>\n

Arbuste<\/a> de terre de bruy\u00e8re, il faut absolument lui \u00e9viter le calcaire qu’il n’aime pas mais il faut aussi l’installer dans un lieu qui ne soit pas expos\u00e9 au soleil br\u00fblant, ce qui lui plait, c’est l’exposition mi-ombre, l\u00e0 il pousse bien et fleurit abondamment.<\/p>\n

Votre rhododendron vous laisse parfois perplexe car vous constatez que son feuillage est moins beau?
Regardez les feuilles, si elles ont des taches brunes<\/a> c’est qu’un champignon est pr\u00e9sent, il faut enlevez celles qui sont atteintes et appliquer un fongicide. Si vous constatez une d\u00e9coloration cela est le signe d’une chlorose, celle-ci est due \u00e0 une mauvaise assimilation du fer lorsque le sol est trop sec, arrosez r\u00e9guli\u00e8rement sans \u00eatre excessif, vous pouvez lui apporter un peu de sulfate de fer.<\/p>\n

Les boutons floraux qui noircissent sont aussi le fait de champignons, enlevez tous les boutons touch\u00e9s et br\u00fblez-les, traitez ensuite avec un fongicide.
Il peut arriver que votre rhododendron se fl\u00e9trisse enti\u00e8rement , c’est le cas le plus grave, l\u00e0 aussi c’est \u00e0 cause d’un champignon, mais celui-ci part des racines, gagne toute la plante qui se retrouve asphyxi\u00e9e car la s\u00e8ve ne circule plus. Une fois install\u00e9e, cette maladie ne peut \u00eatre trait\u00e9e alors il vaut mieux \u00e0 titre pr\u00e9ventif faire des applications de fongicide, bio de pr\u00e9f\u00e9rence.<\/p>\n

Et que faire si le rhododendron boude et ne veut pas fleurir? Les boutons floraux se forment en \u00e9t\u00e9, il ne faut pas trop arroser la plante \u00e0 ce moment l\u00e0 pour \u00e9viter qu’elle ne d\u00e9veloppe trop de feuillage au d\u00e9triment des boutons, veillez aussi au choix de l’engrais que vous lui donnez, les engrais<\/a> pour plantes fleuries de type NPK sont  bien adapt\u00e9s.
Avec tous les soins que vous allez leur apporter, vos rhododendrons vont \u00eatre magnifiques!<\/p>\n","protected":false},"excerpt":{"rendered":"
