Sadly most of my Keitts have MBBS bad. Could fill 3 five gal buckets full of bad fruit. The good ones that are still hanging and started to blush a little red even though they are hard as a rock I pulled and let ripened, took about 5 to 7 days. Not to bad but I can still tell they need to hang longer, not as sweet as a good late ripened Keitt had some pretty good ones in the past.
The problem I have though is I have to complete with the blue jays and squirrels. If I let them hang on they will sure get them before me. Little bas#&#$@ always seem to get the ones I can't see right away and are perfect to pick.
Thinking about chopping it down and replacing it with another variety. I would top work it but the previous owners planted this tree years ago 1ft from the property line, they were brothers. Since then by new neighbors put a 6ft vinyl fence up and its right up against the trunk.
Sucks because I really like the lateness of this tree. Not to many if any varieties that are as late as a Keitt, maybe Neelam.
