can you help me

We have had to recently selling my nans bungalow due to her going into a home.We should have about 90k to invest for her what would you suggest we do with the cash during these turbulent times.My nan has some savings already so can pay for her care for about 6 years without using this money so we could look at putting it away for her for a few years.Any helpful advice would be greatly appreciated.
