When looking for info on fertilizers and plant deficiencies, I came across this page: CANNA CANADA It's from the website of a private company selling fertilizers, but it's very clear and well illustrated. I thought it could be of some help for those who encounter leaf pbs with their trees. Et il y a une version française: Croissante d'informations pour la culture plantes | CANNA France ...and in other languages too: Europe Ceská Republika Deutschland France Italia Magyarország Norge Österreich Polska Russia Schweiz Suomi United Kingdom Other Countries
Thanks for sharing! Here is a direct link to the Deficiency Guide: Deficiency Guide | CANNA Gardening USA Language can be selected from the upper right-hand corner.
