Pickering is the easiest tree to take care of in all ways. It seldom has a problem and I have seen very little Anthracnose issues on my fruit without any fungicides. If you use minimal fungicides, those fruit stay perfect easily.
I kinda agree, so far.
I bought mine (named clubfoot due to the excessively large rootstock dwarfing the pickering graft) and it unknowingly to me then had anthracnose when I got it. I sprayed it and it hasn't had an issue again in 4+ years and I have not sprayed it. For that matter, my Julie seedling also arrived with anthracnose and other fungi the same year I got clubfoot and it too has never had another problem without spraying it, thankfully it's FULL of fruit every year.
So far clubfoot has been shy about producing likely due to its diminutive size. This year I have 5 fruits on it and it's STILL only a bit over three feet tall.
If nothing else I love looking at the little guy when I come home.
