Limit Content on homepage blog posts

The content limit on the homepage on my site [http://bywayguesthouse.org] is limited to about 175 characters followed by [...] and a "Read More" button.

Where can I set the length to show full post without limiting to an excerpt? Additionally how can I change the "Read More" button text?

 

Hello,

Please follow the screenshot given below.

2> Change Read More text: -


Hope it will resolve your issue

Thanks,
