Q. Griselinia Hedging

We have Griselinia hedging surrounding our property. However, with the recent temperatures reaching -15 degrees, I am almost sure the poor thing is in the throws of its last weeks.

As it stands at the moment, all higher branches seemed to have dried out. At the very base of the shrub, the main trunk of it does seem to have some form a sap going into it. There is growth of at leastĀ five years, but we have to make a decision, try our best to save it if it’s possible or remove it and replant before it’s too late. Can you please give me some advice?

It might be able to be saved, but it will be iffy and if successful, it will take some time for it to achieve its former growth. It is not really a decision I can make for you. It is more of cost of new plants vs time and effort for the old plants. Most people decide to plant new rather than go through the effort. You can give it some nitrogen rich fertilizer. That will help to boost the foilage growth.

Q. Grisilinia hedge

Two years ago I planted fifteen Grisilinia as a hedge. Most of them are doing very well. However, one died a year of planting. Iremoved this. A year later I note that another Grisilinia in the hedge has blackening and drooping leaves. I think it is dying. What can I do to keeep the other plants healthy. What is causing isolated Grisilinias to die?
Thank you

This sounds like a specific to cultivar fungal infection. I would recommend putting dolomitic lime and wettable sulfur around each one. This will help kill off anything as long as it hasn't progressed too far. Here is an article for their care: https://www.gardeningknowhow.com/ornamental/shrubs/griselinia/growing-griselinia-shrubs.htm

Q. feeding griselina

I have new griselinia hedge plants put in in January/February time. some are growing great but some have died and some have brown leaves. What can I feed with to bring them along. If they have brown leaves will they survive. I have noticed some have new growth on the bottom because I cut the top off. I really don’t want to loose them as it cost me a pretty penny to have a gardener put them in properly.

Thanks
