The ones I mentioned have all gained a couple to three feet of growth on my
patio. With very little sun.
In fact, it has a built-in " Sun Block "
To me the taste was good and the color nice.
Could they have tasted and looked better? Perhaps.
But for young trees ( one and second ) years, I have been happy.
To add, I have also used, Spray and grow and SuperThrive.
Which I think has help alot.
P.S. I have heard Obsborne Prolific does well in the shade.
