Basil going to seed?

My basil does well for months and months so long as I do 4 simple things:

1. Do not let it dry too much between waterings.
2. Give it nitrogen-rich food (I use steer manure or blood meal) when it starts wanting to go to seed too aggressively. 
3. Prune it back to a few new small fresh shoots to allow it to grow back. 
4. Pinch the flowers off to stop it from going to seed

The plants wanting to go to seed is my biggest problem. If I have to pinch back buds more than once a week, then it's time for manure or blood meal. I find that method works well for me.
