How to schedule Google plus post?

[mentor]

I want to schedule my Google plus post. I can schedule my Facebook and Twitter post for future time by using third party apps and they really works great for me. I didn't be able to find any thing to schedule my google plus posts? So I am wondering how can I schedule my google plus post. I saw some third party paid apps that can schedule google plus post. But I don't want to pay bucks if there is anything free alternative available. Please help me to schedule my google plus post.
