Hi all, I've had an indoor camellia sasanqua bonsai for almost two years now. It was really thriving until very recently, when I went on vacation for five days and neglected to water just before I left, or to set up my usual vacation watering system. Compounding the disaster, it suddenly got hot and sunny in the window where the camellia lives. (Usually it does fine in the brighter light, but I do water more frequently--once every 1-3 days, depending on how dry the soil looks--when it's bright and hot.) When I came back the leaves were mostly still green, but terribly shriveled. (All were at least a little brittle to the touch, though some worse than others.)
For the past week I've just been putting the camellia back on its usual watering schedule (a slow and thorough drench once every few days, but with no standing water and using the same quick-draining potting mix). And moved it away from the bright window.
I haven't done the bark-scrape test but I'm willing to bet the cambium is green all over the tree. There's also still some leaf buds left over from before the vacation drought, though some of the tips look a bit fried. I haven't seen any progress, however... I know drought recovery may just take a long time, but is there anything else I can or should be doing to help my poor little bonsai through this crisis? I'm having horrible flashbacks to the last time I let a camellia bonsai dry out, and that one never made it back to life... Any help from more experienced bonsai gardeners, esp. re: camellia specifically, would be enormously appreciated!
(I understand that camellia are not always happy indoors bonsai, but it was a gift and I live in a high-rise apartment with no ledge/balcony, so my options are limited. It was doing extremely well up until this drying event, and I really hope to be able to preserve it.)
