Abstract

L'invention concerne une feuille de soins de végétaux composée d'une feuille de tissu en fibres synthétiques, d'un ruban souple de tissu en fibres synthétiques, d'un anneau et d'épingles métalliques pour fixer la feuille, dont le corps présente un rapport de protection contre la lumière allant de 70 à 10 %, une perméabilité à l'air de 50 à 120 cc/cm2/sec., et une perméabilité à l'eau d'au moins 300 cc et, de préférence, une propriété de conservation thermique d'au moins +5 °C. La feuille de soins de végétaux permet la croissance d'une plante dont les parties au-dessus et au-dessous du sol présentent un bon équilibre, même dans des conditions de froid extrêmes qui ne favorisent guère une croissance en un milieu naturel.
