I bought some tree fuchsia seeds whilst in New Zealand last year, and have had great difficulty growing them.

Only one seedling germinated and thankfully so far it is still alive, but only just.

It is about 12 inches tall and is on my kitchen windowsill.

All the lower leaves started to dry at the tips and now they have totally died & fallen off.

This is spreading up the seedling, with only the top couple of leaves being unaffected.

It doesn't seem to have grown at all in the last 3 or 4 months.

This doesn't seem to fit in with any of the pests and diseases listed in the FAQ section. I haven't treated it with anything yet for fear of killing it off completely

Does anyone have any suggestions?

Thanks

Elizabeth
