Here's what worked for us:
Our school stresses reading, reading, reading. Thirty minutes per night, minimally, contracted with parent/student/school, and entered in a log nightly. They are also expected to read all summer long. In 1st grade, it can be a combination of parent and child reading. Later on it can be just the child, with help. Over and over. Every night...
With my DS we had to find books that interested him in order to do this, as he found it a chore (we had many downright unpleasant struggles with him over this). I stocked up on every Early Reader baseball book I could find, LOL (K or Step 1 - some new, but many used); also some others he enjoyed like animals and American History, etc. Anything that he found interesting. I kept them all over the house, in the car, etc, so he could easily pick one up and read it. We even took a bag of books with us on our vacation to the lakes this summer and last.
He struggled a bit in 2nd grade. Testing put him in the Reading Specialist's group during school, and he attended a school-sponsored Reading Camp for 4 weeks this past summer on the advice of his teachers, which caused him to miss his beloved baseball camp with his friends. He wasn't too happy about that, but understood it how important it was - some of his friends were struggling as well and had to take more drastic measures, so wanting to avoid that was a motivator for him. He also has a twin sister who he sees reading like it's nobody's business so that was a healthy motivator for him as well.
Thankfully, all our efforts finally paid off. He just started 3rd grade, and I got a call last week from the specialist saying he was doing well, reading right where he should be, and that they'd keep an eye on him, but that he didn't have to be pulled out of class anymore. This was important for him, since he didn't like being pulled out. He sees the hard work paid off. He finally seems to really enjoy reading and learning about new subjects. I let him pick out a book when we're shopping, and I love seeing the choices of books he picks out at the school library. I can't believe my ears now when I hear him read. I'm proud of him, and I think he learned a nice lesson with all of it.
** This is not to say if there is a learning problem like processing difficulties or dyslexia that this method would work. With my son, he was a slow reader, and this is what helped him over the course of two years.
Good luck with your son. Keep at it. Keep it simple and pleasant (as best you can). Make it fun and interesting. Make reading part of your nightly routine, without fail. See how he does with the specialist, and whether they identify any learning problems. Hang in there.
