New lawn thinning out at the end due to lack of sunlight and drainage + issue with the Acer tree
I started a thread few months ago about my new lawn having bumps due to bulbs growing underneath and I had really helpful replies/suggestions so was wondering if you could help me with another issue (2 actually) I'm having.
So my garden and lawn are looking great and for the most part very healthy. However I can see that the lawn is starting to thin out at the end, near the gate. It's still very green but I can actually see the ground/mud through the grass in this part. I suspect this is due to lack of sunlight and poor drainage there. Before my garden was landscaped/new turf laid, there used to be a concrete patio at the end (about 2,3 meters long) so we removed this. I remember the drainage at that end was pretty poor and it was very boggy for a couple of months (we did the work end of last year). My landscape gardener added sand and topsoil to prepare for the lawn and I used a garden fork to make holes in the ground before laying turf to improve drainage a bit.
I haven't really seen it water logged or anything but it does seem to have more moisture than parts of the lawn.
What can I do to stop the lawn thinning out? I spoke to my landscape gardener and he reckons reseeding + a lawn feed would help. What are your thoughts on this? I believe the lawn is a Rolawn and it's rye grass. Should I use rye seeds or a mixture of rye and fiscue (shade tolerant grass)?
The other issue is my Acer Sangokaku tree at the end (left hand side and doesn't' get a lot of sun either) although looked very healthy for a few months, in the last couple of months has started to look like it has a disease on it's leaves. I am not sure if you can see clearly but I see the leaves at the top are dying/dead basically don't look very healthy. What could be causing this and what can I do to remedy this?
Thanks in advance.
