Make sure to check the water pressure from your faucet. To much will pop your hose. Too little and the water won't make it to the end. I have pressure regulators on mine. I have never put mulch over mine, but I did get some new drip line this year that is made to use on top or under soil. The heat has never bothered mine, but I do water very early in the morning. Oh, and dogs seem to think dripline is one off the best chewies ever. My pup chewed up about 200 ft. last summer. Luckily, she couldn't get to the other 400 ft. I'm going to try burying the new drip line this year. If she digs it up--I'll be back to overhead watering.
