Hi Everyone,
About a month ago I started to notice that one of my Lemon trees (Lisbon) leaves at the canopy look either burnt/dead (photos below).
I have 6 Citrus in total 2x Orange, 2x Lime & 2x Lemon and it only seems to be happening on this tree.
The trees were purchased from a nursery in Feb 2020. They have been put into pots that are 4 times the size to what they came in and I water them every 1-2 weeks. We have just come out of winter and entered Spring in Melbourne. We did have a few mornings of frost which I know citrus don't like.
I have been using Seasol Seaweed solution on all trees from Feb to April and then started again last month.
The trees will be put into the ground early next year at our new house (hence why they're in pots now).
Hopefully someone knows what is happening.
Thank you in advance.
Josh
