Hi, I have two coffee (K7) plants that have put on some great growth in the warmer months. They have been on a veranda under shade clothe at all times. Based in Melbourne, we recently had some frosts and at first I thought they had been burnt, but it now appears more like some sort of die-back. Since the frosts, I have placed them under more structured cover with a more rigid plastic but this hasn't stopped the die-back. Naturally, I'm concerned that it will kill them. I've checked pH and it is fine. I've checked moisture, and that is a little on the high side due to the rain we have had. Any advice you could give would be greatly appreciated. Cheers, Andrew.

Thank you for attaching the photo. The trees are definitely showing signs of dieback which is a shame. As you would know, they need to establish in a warm protected spot - that is not to say that they can't establish in a cooler climate, they just need warm conditions. Good drainage is essential if these plants are to grow well. Perhaps the roots have become saturated, cutting out essential oxygen around the root system thus causing the plants to look so poorly. As the plants have already died back from the top, you have not have any choice but to cut back behind that dieback point. At least they have have a chance of shooting again. I have attached a link on how to care for coffee trees in a pot. http://www.abc.net.au/gardening/stories/s2660506.htm I do hope you can get them back to a healthy state.
