Hi. I’m hoping you can provide (or tell me where I might find) guidance on using Monterey Florel (ethephon 3.9%) in lower quantities/concentrations than indicated in the package directions to thin (rather than eliminate) the fruit on my Honey Gold apple tree. I’ve tried, without success, for several years to bring my tree out of biennial bearing by hand-thinning in years with a heavy crop. (It’s difficult for me to reach the top half of the tree safely, so I’m only able to hand-thin the bottom half.) Any advice or direction to resources on using Florel (or other chemicals available to the home Gardner) to thin the fruit of a home apple tree would be very much appreciated. Thank you, Tiffany Walter
