The drip rate is quite often. Faster than you might expect. I don't have a number but it is not a steady flow. A couple a second possibly. The tape you purchased is rated at 40 gallons per hour per one hundred feet. Usual working pressure is 8-10 psi. If the pressure is higher it will put out more water. Max working pressure is 15 psi. At 10 psi each emitter will put out 0.30 gallon per hour. If the drip tape does not lay close to level the rate will vary. I would suggest just getting a 10 psi regulator so you don't have to keep adjusting to get the flow right. Here is a link that might be useful: Aqua-Traxx Drip Tape

I just put in a drip system to water my roses(1yr old), my Italian Cypress' (newly planted, 3ft), my FanTex Ash (newly planted 6ft), and my Mexican Elder (1yr 4.5 ft). I've been looking everywhere, but I can't find out how much and how often I should be watering them. Right now I'm watering every other day my Elder (6 gallons), and each rose bush (2 gallons). I'm watering every day my FanTex ash 6gallons and the cypress 4 gallons. Does this sound right?

My gardens are all drip irrigated, and it's the best thing I did while planning them! My supplies came from Dripworks, who have great customer service and design assistance. Unfortunately, no one but you can answer your question. It all depends on the roses, the weather, your soil, your emitters, your water pressure ... I could go on and on. For some sort of guidelines, let's use my front hybrid tea bed as an example. I have clay loam soil, mulched beds, half-inch supply lines, and one adjustable Shrubbler emitter on each of the 80 roses in that garden. I don't know exactly how much water each of them gets, but running the system for 2 hours whenever it's been dry seems to be enough. I use a simple manual rotary timer on the hose to shut off the water after 2 hours. All of my lines run on top of the ground, but below the mulch. The only part of the system that's visible are the emitters. Hope this helps, Connie

There is no simple answer. It is something you have to determine specifically for your garden, the size of the feeder line, the size of the drip emitters, the type of plants being watered, the soil composition, how well it drains, the size of the bed, the climate, etc. Plus any attempt to determine a set schedule still has to be flexible because the frequency changes as the season progresses and the plants grow. And even then you still have to stick your hand deep into the soil first. So like any method of watering, the schedule isn't something that can be written on a calendar but is done as the plants indicate they need it. So assuming we are talking about tomatoes and only tomatoes and assuming they are in ground and assuming the standard 1/2" line and 1/2 GPH emitters then 60 minutes once a week is a fairly good place to start. But in Florida you may need 30 mins 3 x a week in the heat. That is a lot of assumptions without much info to go on. :-) Dave
