Message par Benoit30 »

Une descente d'air polaire s'est abattue sur le centre de l'Amérique du Nord. Le Texas a été frappé voici quelques records enregistrés à cette occasion.

Le Texas est complètement gelé, même le Mexique n'est pas chaud !
Il y aura probablement de la casse au niveau des plantes, déjà les gelées du mois de décembre à Houston avait provoque des dégâts sur les exotiques (corossol, jackfruit...) :

Un témoignage d'un habitant de Houston :
" [...]. I'm about 40 miles north of this tree, but in Houston, and I lost all my grapefruits, lemons, satsumas, oranges and 1 kumquat. Only survivor in my yard was a 25 year old meiwa kumquat that looks dead, but there are little shoots coming out of the bark on the main scaffolding branches. Virtually all the dooryard citrus around here look deceased. "
USA, Houston, Texas USDA zone 9a

[...] Je suis à environ 40 miles au nord de cet arbre, mais à Houston, et j'ai perdu tous mes pamplemousses, citrons, satsumas, oranges et 1 kumquat. Le seul survivant dans mon jardin était un kumquat meiwa de 25 ans qui semble mort, mais il y a des petites pousses qui sortent de l'écorce sur les branches principales. Pratiquement tous les agrumes du jardin par ici semblent morts.
