I might have overreacted a little bit by cutting off the multi tips of my large plumeria trees. I inspected the ones I left uncovered including succulents and even my Dendrobium orchids and they seem to be ok. Oh well better safe than sorry.
I made sure I saved my 3 plumerias with seed pods (2 Barbados SG/confetti and 1 Dwarf Pink Singapore) and adenium with seedpods.
I lost an inflo
but I have 2 inflos which seem to be viable, or might survive our late winter cold snaps.
