Hi, I'm from Cape Town, South Africa
Earlier this summer me and my GF planted 2 Mulberry trees (Morus nigra)
and they have both almost doubled in height in less than a month (probably only 1m high now)
I worked a lot of compost into the ground around them that I mixed 50/50 with the sand so I believe they have lots of nutrition in the ground and their root system was very strong from what we could see when we planted them.
I noticed some of the leaves are turning brown/yellow I'm not sure if this is a fungus or something.
Plant Nr1 (let's call him Link)
Plant Nr2 (and let's call him Rhett)
Rhett's is quite skinny and long and has been growing fast. the leaves look very healthy and the growth points are a nice lime green color, the only issue is those brown / yellow spots on the leaves and the lower down leaves dying from it.
Link is much shorter and has been growing a bit slower and is a lot more bushy, Link also has the same brown / yellow spots killing the leaves. Link's leaves also seem a bit strange to me, it seems like the edges are folding over (like forming a upside down bowl) and aren't as flat as I know Mulberry leaves to be
What could be causing this ? what can I do to help Rhett and Link ?
