Great post Brad, if those varieties don't do good for you then they mostly don't have a chance by my location which is within 5-miles from coast. Holiday has be nice dwarf tree's but non-bearer also, Nishikawa,Hellen some fruit every year but less than a dozen. Fuerte shy bearer dependes on year and climate Malama small tree in bad place shy bearer for me too. I know most of my avocado's don't do well because I'm close to coast and have constant on shore winds almost. Temps aren't high enough to get good flower sex change during day many days so trees stay male all day. It has been frustrating to try and grow many of the listed varieties here so now just sticking with a few good growers and sometimes bearers of fruit. Keepers for me; Hass, Carmen Hass, Fuerte, Russel, Don Gillogy, Bacon,Hellen,Stewart,Reed even though shy bearer, Zutano, Magoon shy bearer, Mayo-even though is sweet bland,Jan Boyce f.n.(for now),Aravipa. Dud's to most likely to top work Puebla, Old fuerte seedling in process of top working,Holiday. Many varieties I have are on multi-grafted tree's which so far have worked will for my location. Losses Oro Negro, Choquette,Frey,Esther,Stearns,Edranol,Nowels. Up in air still to be determend are Daily 11, Yamagata, and another Fuerte tree I have kept many shy bearing trees because they grow well and give me some fruit and with enough trees or branch graft's I can get a reasonable amount to keep us in avocados for parts of the year. I covet the folks like Brad, who live in opptinal growing area's but then again i don't like the heat so stay close to coast.I have trialed many other varieties but they failed too so now done with trials and sticking with a few shy bearers to get me to the sunset of my life.
