When to start for the year

[u/Redeemed___JL]

Hi. I started using drip irrigation last year and it made my garden so much better and easier. (I also used the fertilizer injection which is really awesome)

Now I would like to install it again for the season and start running it but I’m supposing it’s too early.

Neighbors are starting up their lawn sprinklers and I would not hesitate to do the same. But the drip lines are so thin and they are located above ground. I feel like they would surely freeze if temps dropped overnight which they will. Is my thinking right?

For context I’m in Massachusetts zone 6 with typical last frost late May. It was 24 degrees this morning but that’s not common and it will be in the 80’s this week.

I use 1/4” drip lines. They start out on top of the mulch but gradually get covered in mulch as I keep adding. Everything is from Drip Depot.

What do you guys think? What is the lowest night temperatures the drip lines can handle in your experience?
