Might anyone know what's wrong with my tetrapanax - a few leaves have gone like this - I've cut them off and then a few more have gone. Otherwise it looks healthy.
it looks like cold damage (as opposed to frost damage) early on some plants can be damaged by temps below 5 degrees, particularly large leave plants
Earlier in the season as the leaves came through, some other leaves (at a smaller stage) went a bit like this and I took those off. I don't think it was so cold though - I live in south-east London, and we have not had very low temperatures this winter, or early spring. At the time, I had been watering and wondered if I had overwatered it. After I took the first ones off, things were looking good until I noticed 3 leaves with markings like this. I have taken them all off. and it probably has 4 or 5 other leaves which are normal.
