Help! Calamondin wilted and unresponsive.

Hi @ThroughTheWoods42 I sadly think it had already got caught by the cold.. Also doesn’t look very bright there on that table, they do need good light a bit of Sunil poss.

Did you acclimatise it gradually when you put it outside.? Gradually increasing the time each day it was outside.? You need to do the same when you bring them in as well.. Because otherwise you give kill them with the shock..
Or it doesn’t like the compost it is in or the feed.. If you have fed it, they like a slightly different feed especially for citrus trees as well.. The wrong food will also make it keel over and die..
I am sorry I can’t say something more positive, but that’s my thoughts, others may think differently though..

Just a thought as don’t know how long you have had it.. They also don’t like being pot bound and In a mixture of 1 part each potting soil, organic compost and per-lite or vermiculite. They like plenty of room to spread out and establish a healthy roots . Also I would recommend re potting plants every few years to prevent roots from becoming root bound.
