L’arbre parle. Pas avec des mots. Mais avec des signaux chimiques, des frémissements, des changements de teinte, des silences remplis de sens. Pour le comprendre, il faut désapprendre le bruit, et réapprendre à écouter

Granular Stayguard (flumioxazin) left, nontreated on the right. Near 100% post sedge control from a granular application. Plus crabgrass and doveweed activity. Very unique, useful product.

Lycoperdon perlatum puffball on this #FriskFairyRingFriday. This species likes sand-based rootzones, and those sites can quickly become hydrophobic.
