I purchased a bonsai tree back in June and all was going well until we went on holidays at the end of August. We were gone for 2 weeks but had someone house sitting for a week and they were to water the plants. When we arrived back the other plants were fine but the bonsai was looking very poorly. Since we have been home its been watered regularly but there is no sign of any improvement. The leaves will fall off with the slightest touch.
Can anyone suggest anything I can try.
