Corinto/Marvel 78.41 137
None grafted Corinto 6.4 15

Grower notes May 1All grafted plants are doing well. I think there may be a slight edge that Marvel is doing better than Carnivor on the stocks. I have lost 10 of the 24 non grafted Corinto. Have not lost any Excelsior. Both varieties of non grafted are very stunted. Both non grafted are fruiting heavily on the tops by the new leader. At this point I am not sure any of the non grafted will survive or amount to much production. I have only a few of the grafted plants that are small but look healthy.
