I’ve been asked for advice about reworking an orchard full of orange rootstocks in Greece that was a lemon grove until a fire about 10 years ago. The rootstock has regrown and the owner would like to graft them back to lemon. There are quite a lot of trees so I imagine top-working individual branches would be onerous, so I’ve suggested reducing the top to a couple of branches and budding near the ground with an inverted T during the growing season, then removing the rest of the orange stock once it’s taken and growing well. Someone else has suggested to the owner that they could be cleft grafted. I wasn’t sure about dormancy and timing for the latter. I expect their ‘spring’ occurs during the cooler months but grafting in the height of summer sounds like a bad idea. Can anyone advise please?
