Citrus new growth with thorns

So I assumed this was the rootstock since there are large thorns I normally cut that off but these are growing above the graft! Does anyone know what is going on here? It’s a Yosemite Gold Mandarin in a container enduring extreme temps this summer but holding the fruit.

Citrus are thorny! My TDE3/Tahoe Gold had some massive thorns sometimes before I removed it earlier this year. That’s a sibling to your TDE4/Yosemite Gold. I think citrus will have more thorny growth after pruning, but other stress might trigger it too, so maybe your heat did it this time if you haven’t pruned recently.


I was wondering if the heat could have attributed to this. So weird though. Thanks!
