micro irrigation
 
I'm thinking about micro irrigation (drip irrigation) for my micro
garden. I've noticed that leaving the garden alone for a few days during
the dog days of summer is not beneficial.

Any pointers om either equipment or technique?

It is good to get one of the little Raindrip brochures at your local home
improvement stores--it outlines the types of hoses, connections, and outlets
they offer, and helps you figure out what you need. If your local place
doesn't sell Raindrip, see if they have informational brochures on a
different brand.

I got started by buying a basic Raindrip kit. (I would assume other brands
have similar kits.) It comes with a sampling of their products, and it's a
good way to get acquainted with them. After you set up a line or two,
you'll start to intuitively figure out what you need and can then go to the
home improvement store and get specific supplies. (NOTE: in places like
Lowe's and Home Depot, this stuff is in the Plumbing section rather than the
Garden section.)

I use 6' hoses and splitters to maintain lots of different lines all over my
yard. (You can't have too many splitters, as far as I'm concerned!) This
enables me to open just a few streams at any given time, so I can rotate my
watering.

The only caution I have is that you need to check on the drippers and
connections regularly, to make sure the drips are not clogged and that the
lines stay intact. There have been many times my pipes have popped off of
their main lines and deposited gallons of water all over the yard. (Keeping
a rather low flow helps to ease this.) The drippers have worked pretty well
for two years, but every now and then one will get clogged and will need to
be replaced. It's best to notice this before the plant is affected.

If you ever want to talk about various configurations, let me know and I
will be more than happy to share some of my garden plans. I largely operate
out of rows of 3X6 foot raised wooden beds, but I've got all sorts of other
configurations too. Despite the occasional clogged dripper or popped-out
pipe, I find drip irrigation to be immensely beneficial, and I highly
recommend it.

If you want to stay low-tech and low-cost, try one or two of those
soaking hoses made from recycled tires and see whether they're suitable.
A flow-restricting washer ensures that water just oozes from the hose
along its length, with no spray or puddling. I've found that two
25-footers, with an average flow rate of .75 US gal/min (each), work
well in each of my 3'x8' raised beds. I charge mine through a simple
hose-end valve manifold; the hose has a (inexpensive) 25psi inline
regulator to provide a fairly constant flow rate: I'm on a private
residential water well so system pressure is variable.


I think with my separated plant locations I'll go with the drippers.
I do have a friend with continuous beds (and in sorry need of watering).
I see the soakers cheaply and I think this would be a good plan for her.

If there is a hassle, it is moving the supply hose from bed to bed
but I am able to rotate watering easily and to monitor volume simply by
timing.

Soakers are great for dense rows, like carrots. For larger plants, like
tomatoes, which need to be spaced a bit further, drippers are better.
You'll eventually get to know when it's best to use a soaker, dripper, or
spray. I use all three, in different applications.

I got mine for about $20. It's cheaper to buy the components individually,
but the kit gives you a "Dummies" version! Your description of your garden
elsewhere would probably use a small kit like this perfectly.

I like this idea, instead of one serpentine line, that way you can
reposition the drippers easily as the garden changes.


One thing to note is that, while it is possible to remove drippers and plug
them up (they sell plugs for this very reason), it is rather difficult. the
drippers off can be time consuming, so I generally buy new supplies instead
of trying to re-use old ones. But it is definitely possible to re-use the
old ones if you have the patience for it. One good thing to do is to lay
out one main line, and put a single 1/4" hole near each bed or plot, from
which you run a 1/4" tube that you can alter from season to season as
necessary. Since I rotate the types of vegetables in my beds, I sometimes
need closely-spaced drippers, and other times I need more widely-spaced
drips, or sprayers, or soakers, etc. Putting a single hole on the main line
for each bed gives you the versatility to change things up according to your
needs. It's pretty easy to change out the 1/4" tubes every season.

Are there valves or adjustments to control the rate, or is it all done by
time and fixed rates? It looks like some timers have multiple controls.


There are flow controls and whatnot, but I don't use them. I use only the
barest of technology, and just open my splitters enough to get the flow that
I want. I use splitters ABOVE other splitters so that I can adjust the flow
rate initially, then not have to adjust it again, but simply open the
necessary splitter valve! (Didn't I say I love splitters?) It isn't
uncommon for my water to go through three or four splitters before it gets
to its final destination. So much easier to open and close a couple of
valves every day than to open each one individually and re-adjust the flow
rate every time. Anyway (after this long-winded rant that has little to do
with anything you asked!), you can look into the timers and flow checks and
all that stuff, but I can't give any practical advice on these because I
simply don't utilize them.

In these parts you can buy a kit which would handle that, or make it up
yourself. You need a roll of 1/2 in polypipe, a couple of dozen drippers on
drop lines, some joiners, plugs, bends and tees and a timer switch to go on
the tap. The installation is fairly simple, the shop should have sample
layouts etc to guide you. You will need to experiment with the number and
position of drippers and the length of watering to get the right application
of water for your water pressure and layout, aiming for few deep waterings
rather than many shallow ones. Put the drippers under the mulch! Remember to
adjust the regime according to the weather as hot dry conditions will need
much more water than cool damp.

Get a pressure regulator. A 3/4" tubing (IIRC) take the water to the
1/4" drip line. The drip lines are connected to the tubing with a
piercing tool and connectors. The emitters on the 1/4" drip line will
deliver a predetermined amount of water (.25, .50, 1.0 gal/hr) at
intervals of 6" or 12" (at least that is what I use) for 20 ft..
Connectors are 1/4" straight, right angle, or T. You'll also need some
little plastic posts to hold the tubing in place. I haven't used a timer
but that should be easy. I turn mine on in the morning (every other or
third day) while getting the paper. An hour later, the watering is done,
I turn them off, take my shower and go to work. It's easy :O)

The anecdotal evidence I've been reading seems to imply problems with

I get mine from a local nursery. It is all generic (no brand) but there
are other sizes besides 1/4". The connectors look sorta, kinda like
below. You insert the connector into your 1/4" drip line, and then punch
a hole into the tubing that is the main conduit for the water, and
insert the other end of the connector into the hole that you have made.
You will get the specified amount of water for 20ft. At the end of your
drip line, you inset a cap with the same kind of barb as the connectors,
only there is no hole for the water to pass through.

good advice given so far. Recommend you read the basic rules of thumb
included in the Raindrip.com booklet ( link below) which I found does make a
huge difference in performance(specifically length of 1/2 hose, length of
1/4 tubing and total gph per system) also don't mix emitters up--- keep the
drips and sprinklers on separate circuits if you want best performance.
There is mention of which ones can be grouped together.

http://66.241.193.32/cms/files2/Raindrip_DWME_2008.pdf

I use the micro jets (red tops) rather than the sprinklers which have a
tendency to stick and clog, also the newer adjustable drips ( 0-10 gph)
will give you a bit more flexibility than the 1/2, 1, or 2 gph button drips.

Keep bends and connectors to a min. Ensure you have overlap.

Timer work great, it adds more flexibility in hot weather. I use this Meinor
timer http://tinyurl.com/mjhbzc rather than the similar Raindrip model.
less expensive, better quality.

My area requires an anti-siphon on any sprinkler system as a backflow
preventor even though my sillcock has anti-siphon.

The pressure regulator is good to have especially if you have flow rate
variations. Previous, I had hoses pop out of the 1/2 compression
connectors, which I also changed to screw tighten ones rather than the
push-in compression type as much as I could.

I found there is a size difference in some of the tube pipe and compression
connectors being sold in the various Big Box stores as 1/2 inch poly, some
coming out of China is metric, not quite a fit for compression connectors.
So stay with one brand as much as possible for the 1/2 components.

Don't use the misters for plant watering.

Get extra stakes, you will need em. Kids, dogs, nosy neighbors and such
will break em

Look around to find the more flexible 1/4 tubing if you can, not around much
these days. The newer 1/4 hard poly has a lot of memory.

Ensure you winterize the system.

Be careful, there are differences in the inside diameter of some of the
tubing. I irrigate approximately 700 blueberry plants with 1 gallon per hour
drippers. If you want to see something online go to dripdepot.com. They are
really nice folks and ship fast. Also, their prices are considerably cheaper
than my local Lowes or Home Depot.

Thanks to all. I bought a rain drip Landscape Kit. I didn't see the
Vegetable Kit which has 1/2 gallon (inline) drippers instead of 1 gallon
PC end type and more 1/4" tubing and no 1/2".

Since my garden is compact (runs of 6' to 10' max) I'm thinking the
1/4" line will be easier to manipulate. Should I be thinking 1/4" for
everything using Ts on the 1/4" line instead of piercing the 1/2"?

What's the 10 gallon pressure compensating flow control for? I have
more than 10 1 gallon pressure compensating drippers in the kit.

Is there any info on how much typical vegetables actually need? It is
hard for me to tell when tomatoes, carrots and the blueberries need
water. The cucurbits (particularly the cukes) seem like they always do.

How do I water carrot rows? I didn't see 1/4" soaker hose. Mister, or
just keep hand watering? Or the 1/2 gallon inline every 6"?

Since I have different vegetables I wonder if I should put valves
inline for the different sections and set this up for the water
frequency of those neediest (cukes at the moment) and shut off the water
to the sections that don't need more. That seems easier than changing
the flow rate. The adjustables seem to be 1 to 10 gallon/hour. So
keeping everything in my clayish to normal soil at 1 gph and having
several sequential watering periods and turning off the sections that
don't need more water in the later sequences...

The "bad" news is that I won't be able to put in my irrigation system
because it is raining all week!

You should have at least one main 1/2" line. Having all of the water flow
through 1/4" tubes might cause backup at some point, whereas allowing
several small lines to come out of the big line will keep things flowing
smoothly. I like a single big line just for running along the edge of the
bed, with the little tubes doing all of the creative work among the plants.

What's the 10 gallon pressure compensating flow control for? I have more
than 10 1 gallon pressure compensating drippers in the kit.


I have never used the flow control. I just adjust my flow manually.

How do I water carrot rows? I didn't see 1/4" soaker hose. Mister, or

I hand-watered mine. (I didn't have rows, I broadcast them so they filled
the bed.) Using a mister works well too, but you shouldn't have misters on
the same circuit as drippers. (Use a splitter at the water source.) There
are also 1/4" tubes that have holes every 6 inches, but I have found they
tend to clog, so you'd have to be ready to go out there with a needle every
few weeks. You could also use a needle to put holes in regular 1/4"
tube--that would allow the water to come at intervals closer than 6" if you
wanted.

Since I have different vegetables I wonder if I should put valves inline
for the different sections and set this up for the water frequency of
those neediest (cukes at the moment) and shut off the water to the
sections that don't need more.


That would work. What I do is simply use more drippers on the water-loving
plants, and make them for 1 or 2 GPH instead of 1/2 GPH. This allows more
water to reach each water-loving plant from a single circuit. You can just
turn the flow on and leave for an hour, and all the plants will get their
proper amount of water at the same time.

One thing you need to be aware of is the carrying capacity of your supply
lines. 1/2 inch tubing can only supply a maximum of 220 gallons per hour. I
don't know how much 1/4 inch can carry, but it is significantly less. This
may not be an issue for you, but it most certainly is for larger gardens.

tend to clog, so you'd have to be ready to go out there with a needle every
few weeks. You could also use a needle to put holes in regular 1/4"
tube--that would allow the water to come at intervals closer than 6" if you
wanted.

When I got my 1/4" line with emitters, I was told that emitters wouldn't
supply their rated volume after 20 ft. and that was for 1/2 gal/hr.
emitters. Seems likes it would be a shorter with large emitters. You
would still get water, just not at the volume rated for the emitter.
I think you should keep your 1/2 tubing as the back bone of your drip
system, if for no other reason, t be able to know how much water a plant
is getting.

Since I have different vegetables I wonder if I should put valves inline
for the different sections and set this up for the water frequency of
those neediest (cukes at the moment) and shut off the water to the
sections that don't need more.


That would work. What I do is simply use more drippers on the water-loving
plants, and make them for 1 or 2 GPH instead of 1/2 GPH. This allows more
water to reach each water-loving plant from a single circuit. You can just
turn the flow on and leave for an hour, and all the plants will get their
proper amount of water at the same time.

Since my garden is compact (runs of 6' to 10' max) I'm thinking the
1/4" line will be easier to manipulate. Should I be thinking 1/4" for
everything using Ts on the 1/4" line instead of piercing the 1/2"?


You should have at least one main 1/2" line. Having all of the water
flow through 1/4" tubes might cause backup at some point, whereas
allowing several small lines to come out of the big line will keep
things flowing smoothly. I like a single big line just for running
along the edge of the bed, with the little tubes doing all of the
creative work among the plants.


OK, I've laid out the backbone 1/2" line to run along the edges of
the garden. I think what I'll do is run taps with valves for each
section. Each section will have about 4 or 5 emitters and a max length
of 10'.

I suppose since the backbone runs along the garden path also, I'll tap
off for a few other plants, the roses have taken a beating...

I have a hard time believing that those 1/4" taps on the 1/2" line
don't leak. Everything I've ever done with plumbing leaked! That's why
I'm trying to minimize the taps.


What's the 10 gallon pressure compensating flow control for? I have
more than 10 1 gallon pressure compensating drippers in the kit.


I have never used the flow control. I just adjust my flow manually.

How do I water carrot rows? I didn't see 1/4" soaker hose. Mister,
or just keep hand watering? Or the 1/2 gallon inline every 6"?


I hand-watered mine. (I didn't have rows, I broadcast them so they
filled the bed.) Using a mister works well too, but you shouldn't have
misters on the same circuit as drippers. (Use a splitter at the water
source.) There are also 1/4" tubes that have holes every 6 inches, but
I have found they tend to clog, so you'd have to be ready to go out
there with a needle every few weeks. You could also use a needle to put
holes in regular 1/4" tube--that would allow the water to come at
intervals closer than 6" if you wanted.


OK, I'll do the hand watering here. I pulled a carrot from the edge of
the garden a while back. Although it was almost an 1" in diameter, it
wasn't much longer!

Will do.

I've got a pressure regulator and more tees coming from Drip Depot.

I've shopped at 4 different Home Depots and a Lowes looking at drip
supplies. Amazingly none of them had the same parts. It's almost like
one shipment got divided between 5 stores! I did find some 1/4" vinyl
line made by Mister Landscaper that looks like great stuff.

Raining again...

Might as well. It's just a couple of extra lines and drippers. You may
find that you start to go a little crazy once you get into it. More lines!
More emitters! What else can I water??

By "taps" are you talking about the holes and the connectors that go in
them? I've had a few leaks among my 50 or so holes, but for the most part
they stay pretty tight. They might deteriorate after a few years; I haven't
had them long enough to know.

If you have clayey soil, that'll be pretty common. I always try to grow
long ones, and they just look stupid. It's best to plant the shorter
varieties--that way all the energy can go into filling them out rather than
making them long. Next year mix a little sand in with the carrot soil--that
might loosen it up a bit.

supplies. Amazingly none of them had the same parts. It's almost like one

I've noticed that too! Seems like I have to go to two different stores to
get the full range of what I need. Weird.

OK. I've got it "wired"! The one thing I've noticed is that I seriously
underestimated how much 1/4" line I would need! I've used it up 80'
watering 16 plants with a max of 4 plants per line (with a 60' 1/2"
backbone). No line left for the roses.

Drip Depot from Oregon to Atlanta priority mail took 2 days, I'm impressed!

I'd like to get a timer as I'm often away for a few days. I notice that
they have water cycles from about a week to every hour. Who waters every
hour? Or even every 8 hours?

My thinking is that I should be watering every day or two depending
on how hot. Perhaps with the deeper drip irrigation I can lengthen that.
The cukes are the problem child seeming to need water in the heat of the
day.

With the drippers under the mulch does it matter as much when to
water or should I aim to water after sunrise but before it heats up?

How close to the base of the plant should I put the drippers? An inch
or two?

If someone is trying to get seeds to germinate and live in a very dry area,
they might want to mist every hour or two to keep the soil damp.
