Last year I added a Venturi fertilizer injector. I pre-mix the fertilizer in a 5 gallon bucket and it sucks it out of there. I hit the flowers every 2-3 weeks, and the vegetables as needed.

Thanks for posting this! I had not seen these, but now I'm wondering about the feasibility of adding something like this to a large irrigation system, as it'd save me a lot of time on fertilizing 100+ trees 2x per year. I'm thinking a 5 gallon pail of liquid fertilizer in the basement boiler room, with a siphon located downstream of the vacuum breaker just outside.

It'd also be nice on even smaller systems like the drip nozzles that feed our hanging baskets, using a little 1 gallon jug of liquid fertilizer for those little hose bib-mounted battery powered irrigation timers.

Sorry to Chewwy, for another post that doesn't answer the OP's question. I know these posts really put his panties in a bind, but I already answered the OP in posts #16 and #18.

That's exactly what I have it for. I have a 4-zone Orbit battery operated timer with 4 solenoids.
1 zone is all the flowers and beds in the front of our home.
2 zone is all the flowers and beds in the rear of our home.
3 is the lawn in front of the house.
4 is the greenhouse and veggie planters in the garden.

All the flowers means all beds, planters, bird bath, hanging baskets, etc... those are all pretty much the same head, so same flow rates and easy to regulate. If something needs more water, I add another head VS putting a larger head on, to keep everything sorta balanced.

The #3 zone has a manual T in the line so I can switch it to our fruit trees if needed and deep water them for a couple hours.

The greenhouse has a buried poly line out to it and a 4 gang valve on a post in the house. I leave the drippers on all the time. They feed both inside the greenhouse, outside the greenhouse to the barrel planters, and over to some blueberry bushes we have.

I have a hose with a spray wand out there for whenever I need it. Just have to remember to hit the manual button for zone 4 before I walk out there, or I have to walk back and do it.

The lack of specific information muddles the design. Water pressure is also a factor, because water does not simply fall out of the hose end; it can stream 20' without any problem unless he's spraying into a 20MPH headwind.

I'm beginning to suspect a troll post due to lack of responding to replies requesting more information.

Most boring troll, ever, if true!

Maybe you should quit deleting posts.

Looking at this as a purely mathematical exercise:

EDIT -- (next morning) Now rested and sober, I can see flaws in my argument! I'll ponder it over a coffee...

Isosceles Triangle Calculator

Use our isosceles triangle calculator to find any part of an isosceles triangle. Calculate any leg, angle, perimeter, or area of a triangle.

www.inchcalculator.com

a = 100 (length of hose)
h = 90 (1/2 width of plot)
b = 87.178 feet maximum distance between spigots

I like things to be symmetrical.

With spigots in the corners you'll need 7 spaced evenly along each long side, that would put them at 81' 8" apart.

If instead of placing them at the corners you put the first one 40' 10" from the corner and then spaced them the same in between (81' 8") you could get away with 6 spigots along each long side.

Please don't assume I am right, I would lay this out using survey stakes and take messurments.

Spot on! I just had to draw it for myself to get my head around it.

And no, it's not symmetrical, but then it's just an exercise in geometry, and probably not a practical solution anyway:
