Bass, I'm finding that the soil plays a big part in how figs look. I received 6 cuttings from Herman of Marseilles Black VS, in 2009. One was grafted onto a Hardy Chicago and the other five were rooted.
Of the five rooted, four were planted in the ground and one was kept in a pot, for a back up. I never got a chance to lime the ones in the ground. But did apply a lot of lime to the potted Marseilles Black VS. The Potted fig has a lot more darker color then the figs that were place in the ground without the lime. Even though it's late in the season the potted Marseilles Black VS is nice and dark. But, the in ground ones are half green looking. But just as ripe as the potted ones
We have noticed this with other plants also. One of the reasons why figs have been so hard for us to identify figs and find the right ones for our area.
Are you growing this fig in a pot or in the ground?
