Hey Mark, thanks for the tips. I have never used Bonzi before but that’s good to have in the playbook.
My big LZ tree has a nice canopy and bud are just beginning to push again. We are nearing the end of our heatwave so this push is going to start out vegetative but the nights are in the 50s so there’s a chance it will turn to partial blooms.
I already have a tree that is blooming because of the cold nights.
Here’s a pic of my larger LZ tree
This tree definitely has enough leaves to support fruit, even if going by Dr Yonemoto’s ratio of 60-80 leaves per fruit. I did make sure to give this tree plenty of Potassium, Calcium and micro plus trace including Boron, up until the point where it dropped all its fruit.
The late set fruit on my potted double rootstock LZ tree is still holding on and has a very slight blush of yellow on the shoulders so it looks like I’ll harvest at least one full sized fruit this year. The late bloom was not bothered by fungal issues.
I may try removing early blooms from my LZ trees in order to get better fruit retention on secondary or tertiary blooms.
