How do i communicate between my LAN & WLAN which are on different subnets?

I want to communicate from a PC to a server and vice versa where the PC and server are on completely different subnets. The configuration is:

Router 1 has an ip address of 172.16.13.1(LAN) The PC has an ip address assigned by router1's DHCP client. Router 1 is coected to router2 through a WLAN interface(192.168.1.9) Router2 has an ip address of 192.168.1.1(LAN), gateway 192.168.1.254

PC<->Router1<->Router2<->Server

How can i communicate/pass traffic from my PC to the server which are on different subnets? I have done some research online but as I am not that familiar with networking, I still dont understand how this can be done. Would i need to implement some static routes?

Thank you
