Help! Griselinia hedge is dying.
I'm just looking some advice on whether to give my plants more time or not?
Last year, early October, I started a new hedge in my front garden, about 35-40 plants. I live in South-West coast so the winters are not too cold here Yet they can be windy. The garden is in full sun most of the day. Wind can be strong on occasion but most of the time it's not too bad.
After the winter I had to replace 2 plants as they have gone brown and dead. The rest of the plants have turned green-yellow. Yet they still had new branches and new leaves. They are still green but more yellowish than deep dark green (if you know what I mean). The new branches were darker but turned light yellowish green with time too.
If the weather turns crazy hot I water them.
In my area there are many wild griselinia so I know that it's not a matter of the climate.
I worry they are dying but can't really put my finger on it. It's my first garden ever so I've got lots to learn and most from my knowledge coms from internet or my neighbours.
Please advise if I need to feed it and if so what's the best type of plant food. Could it be that the soil is too alkaline or acidic?
