Une croissance et une verdure luxuriantes : c’est ainsi que vous voulez votre jardin. Mais parfois, une plante s’affaiblit. Non seulement l’emplacement influence la fa\u00e7on dont les fleurs, les arbustes et les arbres se d\u00e9veloppent, mais la nutrition des plantes joue \u00e9galement un r\u00f4le fondamental. Un manque de nutriments se manifeste dans l’aspect ext\u00e9rieur, par une d\u00e9coloration des feuilles ou une mauvaise croissance. Si la bonne nourriture fait d\u00e9faut, les plantes peuvent survivre pendant un certain temps, mais elles ne se d\u00e9velopperont pas. <\/p>\n\n
Souvent, la sous-alimentation est constat\u00e9e sur les feuilles. La chlorose est connue comme le jaunissement g\u00e9n\u00e9ralis\u00e9 au milieu du vert. Les feuilles peuvent devenir partiellement, mais aussi compl\u00e8tement jaunes. Si le tissu finit par devenir brun, il meurt lentement. Ces changements sont appel\u00e9s n\u00e9croses. M\u00eame les fruits peuvent montrer des signes : par exemple, si les radis manquent de nutriments, ils \u00e9clatent. <\/p>\n\n
La cause la plus \u00e9vidente : le manque de fertilisation. Ceux qui ne nourrissent pas du tout leurs plantes courent le risque de manquer d’\u00e9l\u00e9ments nutritifs importants. Une fertilisation unilat\u00e9rale peut \u00e9galement entra\u00eener des sympt\u00f4mes de carence. Mais si vous pensez trop \u00e0 l’apport, vous pouvez aussi vous tromper, car certains nutriments s’influencent mutuellement. Trop de potassium, par exemple, peut ralentir l’assimilation du magn\u00e9sium. Si les plantes re\u00e7oivent beaucoup d’azote, elles ont \u00e9galement besoin de beaucoup de potassium. <\/p>\n\n
Tout d’abord, il est important que la base soit correcte : si le sol sableux est tr\u00e8s perm\u00e9able, il ne peut pas retenir longtemps les bons tissus. Les sols fortement limoneux, en revanche, ne lib\u00e8rent les pr\u00e9cieux min\u00e9raux et oligo-\u00e9l\u00e9ments que de mani\u00e8re tr\u00e8s h\u00e9sitante. Dans les deux cas, il est utile d’am\u00e9liorer le sol. En outre, une analyse du sol peut fournir des informations sur la valeur du pH et montrer combien de nutriments le sol contient. <\/p>\n\n
La cl\u00e9 de la sant\u00e9 des plantes, c’est un apport \u00e9quilibr\u00e9 et adapt\u00e9 \u00e0 la plante. Chaque plante a ses propres besoins. Si les plantes poussent dans des pots et des bacs, les souhaits individuels peuvent \u00eatre facilement satisfaits. Dans les massifs de plantes vivaces luxuriantes, parsem\u00e9es de gramin\u00e9es et d’arbustes, l’apport diff\u00e9rent est un peu plus difficile. Ici, un engrais universel est la solution. <\/p>\n","protected":false},"excerpt":{"rendered":"
