I am a newbi and I humbly would like to ask a pro for some help because I am stuck...I live in Brooklyn NY and am fortunate enough to have a small space to garden. In my enthusiasm I tend to over plant crowd ,and until half way through this summer I have been watering my plants wrong. I just sprayed them with water and for 2 years in a row they have acquired this white powdry stuff on the leaves and stems and what starts as a wonderful small garden ends up a white powdery mess of dying plants...what is this white stuff-fungus? Am I over crowding? I go to the Botanical Gardens in the Bronx, NY and they crowd like crazy and the plants look soooo wonderful. How do they get away with that and does any one know what that powdery stuff is...I have pictures that I can email you if you like...
A frustrated beginner but nonetheless and avid beginner.
Please excuse my fowardness in posting to pros but I need some help.
