I was wondering what you meant by irrigation system. Is it simply that you need access to a hose and don't want to move it every time you mow or do you want something more automated?
Both. I have access to a hose and a spigot, but it is at the house which is about 85 LF away from the closest raised bed. Last year we watered with a sprinkler (overhead watering) that we ran on a long hose from the house. Husband had to move it every time he mowed, which led to it not getting put back, which led to me being lazy about watering. Also, overhead watering spread some pepper disease around that nearly had our entire pepper crop demolished. So I'm kind of over the overhead watering thing and eventually I'd like the watering to be done without much input from me - because I forget. And because we go on vacations.
So the goal is to first get a system of soaker hoses that run off of a PVC/LDPE/PE piping system.
- There would be three hoses running lineally in each 4' wide bed and one (maybe two) in the 2' wide bed.
- The soaker hoses would have caps in the end of each and would be run in parallel to minimize loss of water pressure from long runs of soaker.
- We have 100 psi water at the house, so I'd likely need a regulator, but I should be able to manage by turning down the valve at the house.
- I don't think I want to do direct drip irrigation since I rotate the plants around and the design next year will likely be different than next year.
- Plan is to run it off of the same "hose over the yard" thing we are doing now, but look into burying something if the system works well.
- Plan is also to have it set on a timer so I can't forget to water things, or get up even earlier in the morning just to water plants.
My current research is really in system layout (Do I really need to be able to turn off each box? Or just the trees? Or maybe just the herb box? IDK yet.), materials (PEX fittings are awesome, but are not UV friendly, so maybe PVC? maybe polyethlene? maybe just a garden hose and some hose clamps?? I don't plan on burying the box pipes too much if at all so they can't break when stepped on.), and the like.
I have a couple of weeks to figure it out though, so that's good. Suggestions from the peanut gallery?
