Yes--mine sprays about 5-6 ft. width under med. pressure so will go up or down accordingly.
Yes there are holes throughout the hose. The last hole has the most water coming out though.
It is supposed to be used for irrigation purpose. Doesn't matter
I'm not sure if the path is dependent on water pressure. At the ends of the hose the spray is usually 5+ feet. In the middle it can be 3 feet with much lower spray volume.
No, it does not come in black.
I loop the 50' length hose easily around all the plants in the foundation beds around my house - starting with the plants closest to the house, then looping back to the opposite end of the bed by snaking the hose around the plants in the middle and front of that same bed. However, before I hook the hose to my outdoor faucet and start laying it in the flower bed, I uncoil it and put a paving stone or brick on each end of the straightened hose on my sidewalk or patio on a sunny day, while I go do other chores for an hour or so. This way, the hose softens up a bit and is more flexible before you start arranging it the way you want it.
I used one 50 foot hose and 1 50 sprinkler hose. It worked fine.
That depends on how much pressure you get from your faucet to move the water through the hose and if any of the beds are at a higher level than the flow of water from the faucet. One of my outdoor faucets is at a lower level on the West side of my house, so I use 2 of these hoses to water the beds lower than that level on that side and one of my front beds. The faucet on the East side of my house is at a higher level so I have one of these hoses that I connect to an 8' extension hose from that faucet, then snake the Gilmour hose between the plants in a raised bed near my back porch, then, due to a 4 nozzle connector I have on my faucet, I connect 2 other Gilmour hoses to water the side and another front bed, leaving one nozzle at the faucet empty so I can either fill a bucket directly, or attach another hose to hand water, or wash my car.
In my case I think at least 24 hours to get any where near an inch. The water comes out in a mist, not much volume.
