Les vagues de chaleur avec des temp\u00e9ratures sup\u00e9rieures \u00e0 30 \u00b0C ne sont plus une exception en \u00e9t\u00e9. L’augmentation de la temp\u00e9rature de l’air fait que le sol se r\u00e9chauffe \u00e9galement. Plus le sol est chaud, plus l’humidit\u00e9 s’\u00e9vapore rapidement. Si vous pailletez les parterres, avec des tontes de gazon ou d’autres mati\u00e8res organiques, vous permettez \u00e0 la temp\u00e9rature du sol de moins monter et vous le gardez plus humide. Une plantation dense de plantes vivaces, de fleurs d’\u00e9t\u00e9 et d’arbustes a un effet similaire. Les parasols et les voiles prot\u00e8gent du soleil br\u00fblant, mais les arbres fournissent \u00e9galement une excellente ombre par temps chaud. Ils veillent \u00e9galement \u00e0 ce que l’int\u00e9rieur de la maison ne se r\u00e9chauffe pas aussi rapidement. Alors que les surfaces en pierre emmagasinent rapidement la chaleur pendant la journ\u00e9e et la restituent lentement la nuit, les \u00e9tangs, les parterres de fleurs et les toits plats verts garantissent un agr\u00e9able refroidissement par \u00e9vaporation. <\/p>\n\n En hiver, il pleut plus que par le pass\u00e9, mais en \u00e9t\u00e9 les pr\u00e9cipitations ont tendance \u00e0 \u00eatre absentes, ce qui menace les p\u00e9riodes de s\u00e9cheresse. C’est pourquoi il est pratique de recueillir l’eau dans des barils de pluie et des bassins collecteurs afin de pouvoir puiser \u00e0 pleins bords pendant les p\u00e9riodes de s\u00e9cheresse. Si le sol a une bonne composition, il peut mieux stocker l’eau. Les sols sableux ont besoin de min\u00e9raux argileux pour cela, et les sols limoneux peuvent \u00eatre ameublis avec des mati\u00e8res organiques et du sable. La s\u00e9cheresse est tr\u00e8s dure pour certaines plantes, mais pour d’autres, ce n’est pas un probl\u00e8me. Remplacer les esp\u00e8ces les plus exigeantes par des esp\u00e8ces n\u00e9cessitant moins d’entretien vous \u00e9pargnera beaucoup de frustrations et d’arrosage. \u00c0 propos, c’est la pelouse qui a le plus besoin d’eau. Peut-\u00eatre peut-on en r\u00e9duire la surface au profit de couvre-sols tol\u00e9rants \u00e0 la s\u00e9cheresse ? <\/p>\n\n Les fortes pluies pr\u00e9sentent deux dangers pour le sol : L’un est la menace d’\u00e9rosion, l’autre est l’inondation si l’eau ne peut \u00eatre absorb\u00e9e. Les plantations denses aident dans les deux cas. Les nombreuses racines maintiennent le sol en place et le prot\u00e8gent ainsi de l’\u00e9rosion. Elles ameublissent \u00e9galement le sol, qui peut ainsi mieux absorber et retenir l’humidit\u00e9. Pour le jardin, cela signifie que les plates-bandes doivent \u00eatre paill\u00e9es ou plant\u00e9es dens\u00e9ment. Si la surface est ameublie r\u00e9guli\u00e8rement, elle peut mieux absorber les grandes masses d’eau et les transmettre au sol. <\/p>\n\n L\u00e0 encore, un sol nu est expos\u00e9 aux intemp\u00e9ries sans protection. Si le sol est nu, les vents forts le priveront d’eau – une autre raison de pailler ou de placer les plantes pr\u00e8s les unes des autres. Pour \u00e9viter les dommages caus\u00e9s par les temp\u00eates, il faut v\u00e9rifier r\u00e9guli\u00e8rement que les arbres et les arbustes ne pr\u00e9sentent pas de branches pourries, voire mortes. Au demeurant, les haies luxuriantes constituent un coupe-vent efficace. <\/p>\n\n Les cons\u00e9quences du r\u00e9chauffement climatique se font \u00e9galement sentir dans nos jardins. Les p\u00e9riodes de s\u00e9cheresse et les vents violents ass\u00e8chent le sol, les fortes pluies endommagent les plantes et emportent la terre. Les fortes chaleurs stressent la v\u00e9g\u00e9tation tout autant que les surprenantes gel\u00e9es tardives. Les derni\u00e8res ann\u00e9es l’ont clairement montr\u00e9 : Le changement
