I do not think that there are any perfect gardeners - and those that think they are do not understand nature.
I make mistakes all the time but that is how we learn and it is a humbling experience.
A very good friend - sadly no longer with us, grew indoor plants on a wholesale basis and I remember walking through his plant tunnels and remarking how perfect all the plants looked and his reply was that growing plants makes you realize that nothing is ever perfect all the time and you can wake up one morning to find that everything has been wiped out by green fly -and this is something we should always remember.
So true
