Brown leaves.

Hello there,
My mother has had these plants (wisteria and magnolia) for 15 years but this year the leaves have turned brown at the outside edges.  Does anyone know what could be causing this. They are both in large pots. Any suggestions gratefully received.

I think you have the answer already, they're both plants that don't live very long in pots. What constitutes a large pot btw? And are they top dressed and fed annually? Fifteen years is a long time and they'd hopefully have had a few repots by now.

Both of those need huge quantities of water and are difficult to keep going for long in pots, as @amancalledgeorge said.  Given the weather this year, it has been difficult to keep anything at all in pots going and I had a couple of sorry-looking potted magnolias which looked just like that one and the issue was 100% caused by me not watering them enough.  Now they are in the ground and have had 2 bucketfuls of water, twice a week, the leaves which had brown crispy edges have now all been replaced by the trees, and they look much healthier.

Thank you Amancalledgeroge and BobThe Gardener so much for taking the time to respond. The information you have shared is really valuable. I will let my mother know and get round and repot them both.
