There is very little strength involved in long hill climbing. At 300W and 90RPM the peak force on your pedals is around 82lbs.
Anything you can do to increase your threshold power will help with hill climbing. The standard intervals for that are 2x20min with 5 min rest. Ride these as close to your threshold power/HR as possible 2-3 times a week and your power should improve. You can do these intervals on the flat or on a hill. Hills are usually easier for motivation but it doesn't matter much where you do them.
