But seriously, it is kind of difficult and it depends on your definition of social media. Is Hacker News a social media to you for example?
I've had some great success in the past just posting my articles here. As you can see from my post history I'm not exactly "active", posting 6 times in the last year.
There is always the traditional routes of paying for targeted advertising, email campaigns and so on. However this depends on the type of "growth" you want. Does your blog have a comment section? If not you kind of need to post it somewhere for you to get any feedback whatsoever. If you are writing solely for the purpose of advancing your own career I struggle to see why the articles would be interesting to read for others. So I at least suggest having some other motivation than that.
I realise that my answer contains a lot of "ifs" but it is really hard to answer such a vague question without any particulars.
I really like the idea of adding comment section to my blog posts.
I'm adding the link to my profile as well.
I suspect growth will be slower if you don't interact at all on these platforms, but by the sounds of it that would be an acceptable trade-off for you.
On my biggest post/article I did not have the time or effort to respond to even 10% of the comments here, and that is/was totally fine. The article and its comment section on HN had a life of their own which I was not required to partake in.
