Hello!

I'm pretty new to square foot gardening and am trying to get things ready for the spring. The beds with Mel's Mix (1/3 vermiculite, 1/3 peat, 1/3 compost) are all ready to go and I'm working on the dripline irrigation now. I've purchased the brown 1/4-in tubing with embedded emitters that drip at 1/2 GPH. I have rolls that have emitters spaced at 6" and rolls at 12".

My question is...what is the ideal lateral spacing of the driplines? And should I use the ones with emitters spaced at 6" or 12"?

Due to the layout of my yard my beds are all long but narrow, ranging from 2' wide to 5'. I don't think that would factor into the lateral spacing, but just to give the whole picture.

Thanks in advance for any tips!
