Irrigation plan.
I hope it makes sense.
I only use Rainbird irrigation hose. It has a green stripe down it and I find it at Menards. Other brands kink too easily, or dent and then leak and they aren't 1/2 inch.
Don't use COMPRESSION fittings. OH what a nightmare when they blow. The hose gets soft and flexible in the sun and doesn't contract until enough cold water flows through. Compression is a nightmare
I use the barbed fittings and I get those at ACE hardware, also by Rainbird as well as the 1/4 inch tubing and the female and male end pieces and caps, which are hanging in the HOSE repair section. You will need 1/2" size.
I screwed up my drawing on the upper beds. I made the T connector in the wrong direction. It needs turned so it is an upside down T in the bed with a short piece of hose and a hose end and cap on it so you can drain the upper bed and the lower bed separately in the fall. L elbows make the turn at the top of both sides of the beds and then a normal hose curve to the lower bed is fine.
You simply cut your hose to length and shove the connectors into it. for the hose to the plants you poke a hole and shove the 1/4"hose with a barb shoved into it into the larger hose. The other end of the 1/4inch has a sprinkle end on it of your choice. You can make these 1/4 inch hoses as long as you want and move them from plant to plant from year to year. You can clothespin them to a trellis or sticks or whatever.
There is also a pair of Ts uphill of the beds with ends and caps on them to drain the system uphill of the beds in the fall. You drain and leave the caps off all winder.
The whole hose is just laid on the ground and held down with landscaping staples, also menards (garden center).
So length of the black rainbird 1/2" hose.
roll of the 1/4 inch tubing.
Pkg of 10 barbed 1/4 inch connectors
pkg of sprinkle heads of your choice
landscape staples
1 -1/2" female hose end
4 -1/2" male hose ends
6- hose end caps
8- L -90 degree elbows
4 -T shaped connectors
A rainbird tool. I prefer the one that looks like a funky scissor/stapler. It cuts AND poke holes.
Ask if I screwed up or you have questions.
