I thought there might be hope in chip budding nut trees when I learned a Texas or California nursery that chip buds pecans late in the year while the bark is still slipping. This was prior to reading Bill Reid’s pecan blog where he is adamant that chip budding doesn’t work for nut trees. My buddy and I did 20 or more chip buds one afternoon last year and later in the year at the correct time and we had zero success. The chip’s we did were on well established & in ground rootstocks. I doubt I’ll try again. I remember saying to my buddy time after time ‘wow I’m getting perfect matches on my work.’
Mega chip budding on the other hand does work. I showed how to mega chip graft in this tutorial
