Late response, pretty sure care tree did not go under.
They were loosing ground quick in my part of the country to other spade companies though. Lots of nurseries around here abandon care tree spades do to the simple fact there was better, more reliable spades available plus,the local dealer manager that sold care tree is arrogant, wich did not help sales neither. Care tree spades did number fairly high around here but that has quickly been changing.
Care tree did revamp there spade design, A very good move I believe. They look ALOT like a dutchman or a red boss spade now.
Our contract diggers use dutchman and lemar spades.... Having ditched care tree altogether
