I didn't want the SHD method but am opting for naturalizing the olives. The primary 3 are Itrana (Italian), Salonenque (French and I found fussy) and Chemlali (Tunisian). The ones which were 2 gallon has the best summer growth. Next time I will opt for the 2 gallon to get off and running easier. Good luck! We're having a blast with this new venture and all I'm learning!
