Secondo Avocardo (forum)

Roy starts with ...
I have a secondo purchased from Daleys about ten years ago. This variety is meant to be self pollinating. There have been a couple of seasons where I got a few fruit (good quality :)) but last season all the blossoms dropped. This year (Sept 2019) the blossoms look very healthy and there is good bee activity but I was wondering if anyone has had any success with hand pollinating - if so how did you go about it ?
Thanks

Didnt know Secondo has been around over 10 years - Mines not as progressed yet but the core influence for Avos down south is nights around 10 to 12c and days over or around 17c for self fertility - you may have warmer days but night are too cold still - i do have a Bacon nearby but bees dont pollinate unless you own a hive - Hover and Checkered flies do the work around me - just noticed your not Heathcote in Vic so you do need a B type - In Vic we dont but could help?

Found this in an article i saved - California relates to Sydney and South i guess


In fact all avocado flowers are both male and
female at various points in their life cycle, making it possible for avocado trees
grown in areas with mild climates to self fruit without the help of another tree acting as a pollinator.
Type A varieties have flowers that open as females on the first morning that then
close that afternoon. The next afternoon the flowers open again but this time they
are male. They shed pollen for a few hours and then the flower closes again, this
time for good.
Type B varieties open as females in the afternoon of the first day before closing
and then reopen the next morning as males.
This flowering pattern is only typical in tropical climates. Here in California where
we enjoy more mild temperatures during the avocado flowering season, this pattern
is interrupted, causing the male and female cycles to overlap and resulting in self
fruiting avocado trees. Commercial avocado orchards still commonly interplant
Type A and Type B plants to insure heavy crops. If you want to mix more than one
type of avocado tree together in a back yard setting, it is possible to plant more than
one tree in the same hole or plant the trees together with as little as 4 feet of space
between the trunks. But remember, avocado trees can grow up to 25’,
so select variety planting site carefully.

Hi Markmelb,
Yes I am in NSW, just south of Sydney. First purchased this tree in 2008 but moved to its current location in late 2010. I don't have a lot of room for another Avo, the reason I chose the Secondo was it supposedly didn't need one. Might try a bit of hand pollinating once I work out the flowering pattern.
