I have 4 golden nuggets from 12-5 years old and they all do that unless I can go in early Feb and harvest about half of them. Theyre still good early Feb but it doesnt always keep branches from breaking. Its also the only citrus I prune with any regularity, keeping branches short.
Yes, I am discovering this is the case with my Tahoe Gold. I thought it just had more of an outward growth habit but it will need selective pruning. It would be fine except for the intense summer sun burns the exposed branches. Lesson learned!
This is a bit off topic, but my Tahoe Gold (in the ground in the greenhouse) was spreading too much last spring, so I pruned hard in early summer, the mid-summer flush had ENORMOUS thorns. It was almost a thornless citrus before that, but it seems to get pretty aggressively thorny in response to heavy pruning. Just something to keep in mind.
Mine just started its late winter flush in the last week, hoping it'll be lots of flowers because last year it only held one fruit that a squirrel stole when the greenhouse door was open last summer.
