Watering - Raised Beds w/ Drip Irrigation
Hi everyone - Long time lurker, and first time poster here. I'm managing a community garden in Austin, TX, and we've installed 1/4 dripline irrigation w/6 inch spacing in raised beds that are 16 inches tall.
The irrigation system is relatively new so I'm trying to get the watering adjusted. I've read about the 1 inch per week rule but that doesn't really translate to a drip system that well...at least as far as I can tell.
Now that the weather is cooling in Austin (highs in the low 80s) I'm thinking about watering once a week for 45 minutes but I'm not sure if that's too little or too much. We're using a high quality garden soil w/compost and good drainage in the raised beds.
Thoughts? Should I just start with the 45 minutes and see how it feels after 5-6 days.
