you want them to all have similar growth rates
You could use all one variety. If you still wanted multiple varieties, once you have the desired amount of braiding, you could graft whatever you want on top.
It takes me a couple of minutes to move the tree in and out every year,
and once every 3-4 years, an hour or so to root prune and re-pot (with help)
It takes atleast an hour or more to tie up and wrap a mature tree in the ground,
then almost the same amount of time to untie and unwrap the tree in the spring.
Larger the tree more time it takes.
Trees grown in tree form are also harder to wrap than those grown as a bush.
Over the past generation, tens of thousands, if not hundreds of thousands of
fig trees in the NY area have perished being grown in the ground.
When grandpa got too old to wrap his trees, and there was nobody to help,
they went unwrapped, a small amount adapted and survived,
but most died within a few winters. Lots of unique figs that were brought to this
country were lost this way.
Containers are not a sure thing either,
I know a person in MA that had over 100 Belleclare trees,
all different varieties, they were kept in a trailer for the winters.
One especially cold winter there was a major loss for this collector,
only 4 of the varieties survived.
Off to prune and put away the last few trees for the winter,
weather pattern is chaning this week, old man winter is coming.
Maybe I will try to take a few more not so good pictures :-)
Thank's for the advice Jack, I am making up a plant to pair some nice varieties together but need to observe the growth this year to see what to put with what and to try and get several different harvests on it throughout the season, look forward to more pictures and information from you.
