Irrigation Options for Watering Your Plant Beds Like a Pro


Welcome back to my series on elevated beds! In this post I am going to discuss different watering and irrigation techniques, and how they stack up.

One of the best things about raised garden beds is their ability to drain well. traditional cultivation practices are more susceptible to soil erosion and loss of natural nutrients in the present if heavy rains are prevalent. How much and often you will need to water your beds will depend on your zone, region and normal patterns of rain. This year has felt like an “el Nino” kind of year.

But it seems like most of it came in the wintertime when my beds were dormant. Now it is spring and the rain we’ve been getting has dropped off quite a bit. As I write this, we’ve gone for about a week without. Spring rain is invigorating and makes the air feel clean and good. Winter rain is -well, icky and makes you feel as such. Anyway, letely we’ve had to begin irrigating our beds on our own when we’re having these dry periods.

We’re been using a sprinkler attachment, you may have used these, they oscillate on a cycle so if you have multiple beds they should be well saturated. WE have three beds and the arc does reach them all effectively. This sprinkler has 4 different cycle settings, semi circle, quarter-circle, and full circle.. I had to choose the full circle option as the entire length of the beds wasn’t quite getting wet enough.

I let it run for about half an hour and I’m pleased. Of course, I had to get out of the way quickly when I got that full circle setting working, as I was in the path too!

This sprinkler we have here is the Pro by Orbit – it has a maximum square foot coverage threshold of 4000 square feet (*the whole backyard is roughly about 50 by 50 feet) and operates at a 80 psi.

If you have smaller beds, and only one or two, a hand attachment nozzle may be all you need/ When I was using this for individual plants in the past, I chose a moderate misting setting and hovered over each plant for about a minute to get the right amount of saturation. Of course, it’s impractical and time consuming if you have a lot of crops. So a hands-off system is a good idea, like the one I described earlier.

Sprinklers are mostly associated with wide expanses like lawns, so when you have multiple garden plants around, it pays to use a more efficient water system. Because our beds are long and low to the ground, it did have some benefit to our need.

And another option to consider is…

Drip Irrigation

Drip irrigation systems can be great for your beds…they consist of a series of watering apparatuses that can be placed strategically throughout the beds, and the outflow can be adjusted to get the right level of moisture. They could include different connectors, like t-shape, four-way, and elbows.

Some you can insert into the soil with stakes like the ones that come with solar lights. So your crops get all of the water they need, and none of what they don’t. All of them include a pipeline main tubing which connects to your outside faucet line. There are also fittings and end plugs to prevent leakage, and sealing tape.

The nozzle attachments include misting and look like a fan pattern, and some with multiple drip holes.

If you’ve ever momentarily paused through the produce section of a typical grocery store, you may have been startled (at first) to see a misting spray come on at various intervals. The concept is pretty similar.

There are two different types of drip irrigation systems, which I’ll explain below:

Drip Tape

You may have heard some gardeners talk of drip tape what is it, exactly? It is not exactly “tape” per se, but more of a kind of tubing, constructed of a material like polyethelene, that is flat but when the interior comes into contact with water and pressure, it expands just like a typical garden hose.

It reminds me of something we bought last year called a “Magic Hose” which in its coiled state, is contracted until water hits it, and expands as it fills with water, making it easily storable when not in season. Drip tape is carried by the yard adn while it’s mainly used in large acreage environments, that are long and linear, it can be used in beds if the length is trimmed to fit them. There are small perforations at different intervals that the water emanates from.

Drip Tubing

The concept is the same but it is an actual three-dimensional tube. Both of these connect to a main pipeline.

It is a good idea to bury the tubing or tape at least 6″ in the ground to protect it from heat and prolonged sunlight, and possibly nuisance animals like gophers or mice that could chew on it.

Their advantages are mainly, over traditional “soaker” methods:

  • The low pressure systems help conserve water by delivering it where it is needed and in “trickles” strategically placed, so you save water AND money by doing so.
  • The water supply goes mainly to the root systems, and less to plant foliage, which is important for nourishment.
  • It can minimize soil erosion.

Using a Soaker Hose

Recently we introduced a different kind of irrigation tool – a soaker hose. The BF spotted it right away at a yard sale (Yes, we’ve found good garden tools at yard sales. It’s definitely doable!) This is better than the sprinkler, for sure. Soaker hoses are excellent for elevated beds as they distribute water at low pressure rates (about 10 psi) at a slow rate, very much in the same manner as the drip tape does.

The biggest difference is that it is more manageable (they are about the size/length of a conventional garden hose) and less expensive than drip tape and tubing. Plus, the water is directed where you want it – towards the roots – which means you save money, time, and of course, water.

The spots where there are openings on the hose can disperse water within a 1-3 foot range. You can let it run for about a half-hour to supply adequate moisture.

Before You Choose a System…

You may need to measure the perimeter of your garden to determine the correct amount of tubing you will need for adequate coverage. The irrigation kits most likely will have adequate lengths of the most important parts, like the main tubing. The number of stakes and fittings may vary so please perform due diligence before you shop. good luck!
