Is there any way in the graph below that I can label the V2 treatment only?

I am using the below code.

df1 <- ddply(melt_df, c("Trt", "Crop", "variable"), summarize, 
             N=length(value),
             Mean=mean(value),**strong text** 
             sd=sd(value), 
             se=sd/sqrt(N))

ggplot(df1, aes(x=Crop, y=Mean, fill=variable))+
  #geom_text(size = 4, position = position_stack(vjust = 0.9))+
  
  geom_bar(position=position_dodge(), stat="identity", colour='black')+
  geom_errorbar(aes(ymin= Mean - se, 
                    ymax= Mean + se),
                width=0.2,
                position=position_dodge(0.9))+
  facet_wrap(~Trt, nrow=2)+
  geom_text(aes(y = Mean+10, label = round(Mean, 1)), 
                        position = position_dodge(width = 0.8),
                 size =2.5, vjust = 0, hjust = 0.5) ```


My dummy data is
