Zands- my thinking on zip tie vs clothes pin is that zip tie provides a better form fit to any thickness branch you are grafting with concentric pressure evenly distributed vs a clothes pin acting off a fulcrum and pressure maybe less evenly distributed, also don’t think the rubber band is necessary 🤔. Really looking forward to next season to graft up some more annonas and mangos, growing out some rootstocks now.
