Hi, I am a newbie to firs, more of a JM keeper and I was hoping for some advice regarding a potted Normand Fir I have kept for 3 years. It’s about5.5ft now, was 3ft when I bought it, has grown strongly with good colour. Over the past 5months I have noticed some of the mid and lower branches have brown ends to some of the needles. On the truck, the needles look healthy at the top half but seem to have dropped off or gone brown on the lower half. I have been potting it on every year. I potted it on just before Christmas into a 90ltr pot with a good dose of ground soil which is clay based as I thought the extra nutrients would help as I had noticed the browning getting worse in the run up to winter. I have recently purchased a liquid seaweed tonic and given it one dose of that. Would more help monthly? Any ideas welcome..my assessment is that it needs to go in the ground and keeping firs in pots can only really be a short term arrangement. I’ve not really got a good spot to put it in the ground. Has anyone had any success. Keeping these in pots for more than 3years?
