I was taught to graft stone fruit using 3M #33 electrical tape. This tape is superior to almost every kind of electrical tape. It stretches a bit when cold, doesn't stretch too much when hot. Most hardware stores stock 33. It stretches a bit as trees grow. I typically leave it for a year before peeling off.<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">The next thing you need is parafilm. wax sheets to wrap and seal the graft so it doesn't dry out.

May 70% success rate. I've only tried citrus a few times with maybe 40% success. That included two grafts made in September that didn't start growing until spring. But, if you don't try the success rate will be 0%.<br></div></div><div><br></div><div><br></div>
