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!

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:

I need to place spigots so that a 100 ft hose will reach everywhere inside and not have any dead spots that cannot be reached?

A 100 ft hose would make a 200 ft circle.

 

[Oz_Kioti]

Good brain food, this!

Bearing in mind for this theoretical exercise, we're limited by hose lengths of 100 feet.

The OP's proposition was to install spigots on the corners and only around the perimeter. But - ignoring the corner spigots for the moment, and instead placing a spigot mid-position on the short sides, you would then just require four suitably placed spigots along each long side: TOTAL - 10 spigots.

Not the way I'd do it, but ..... I'm not doing it!

He said "trees" remember. Pulling a hose into a straight line will be practically impossible. I suspect in practice, 75' is more realistic.

The drawing doesn't show any "trees", remember?

I went by what he said, didn't want to remove any more trees, then said trees in center..

 

[Streetcar]

This kind of thing was never my thing.

I’ve cleared a piece of land enough to have the sized perimeter that I’ve shown.
At what intervals around this known perimeters ( length and width ) would I need to place spigots so that a 100 ft hose will reach everywhere inside and not have any dead spots that cannot be reached?

I’d rather have a little wiggle room versus stretching things to their limit.

I don’t want to have to remove any more trees ( in the center) than I’ve already done and although tree’s will change the reach of the hose we can manage that on an individual basis as it occurs.

I’ll have a spigot for sure at all 4 corners
Thanks if you can figure this out

When I planted trees I had several hoses and watered as I walked down the row. It was a workout but ended up being the easiest way to water all the trees without damaging any

Apparently we require more details.

[1930]

Place spigots at 80-foot intervals along the 490-foot sides (left and right, at
0,80,160,240,320,400,480 and one spigot at the midpoint of each 180-foot side or 90'. This requires 16 spigots total to ensure a 100 ft hose can reach every point inside the 180' x 490' rectangle without dead spots.

Thanks, this is what I’ve laid out per your instruction and it’s gonna be fine.
I appreciate all the responses

 

[tradosaurus]

Apparently we require more details.

Also need to know the distance the sprinkler will eject water as well as a layout of where these trees in the middle are located.
