Rain Drip Irrigation Installed in Square Foot Garden

I really enjoy my gardening and learning more with my projects – especially as it relates to rain drip irrigation and square foot gardening. There is always something to learn. Yes, the setbacks are disappointing but there are occasional wins and doing and sharing these with my daughters is really fun and provides us some time together. Square foot gardening recommends that I hand water the plants every day but my busy schedule doesn’t allow for that. I also installed a rain water collection system last Fall and I really want to see if it is useful for garden drip irrigation in my container gardening. I added some piping from my rainwater collection system to feed a drip irrigation system and built a rain drip irrigation system.

I tested my rain drip irrigation system with a long water hose to make sure that I sufficient water pressure at the hose bib to drive the drip irrigation emitters. Once I determined that the combination of approximately 6 feet of downhill slope coupled with 10 feet of water column volume was enough to drive the emitters, I installed permanent PVC piping down to the container garden to install a permanent hose bib. My water supply for my drip irrigation garden system is now fully implemented.

We don’t often have very cold weather in Texas but it does freeze occasionally and I only buried my water supply pipe a few inches under the surface of the soil. I don’t want a freeze to burst my pipes and destroy my rain drip irrigation supply line. So, I put a hose bib at the end of the rainwater collection system supply line so that I can drain my rain drip irrigation system each Winter. There is only about 150 feet of pipe so I think this simple solution will be fine.

Splitter for Garden Drip Irrigation Options

I installed a simple hose bib splitter at the hose bib of my rain drip irrigation system. I’ve had trouble with hose bib splitters in the past but I think I was trying to do too much with them. This arrangement is much more simple. I have one side of the hose bib splitter to feed my rain drip irrigation system and the other side feeds a very short hose for incidental watering as I need it. The hose bib needs to be full on to supply enough pressure to drive the emitters in the drip irrigation garden system.

I used the separator lattice from square foot gardening as the supports for my rain drip irrigation master hose. Each square in my garden has a dedicated small hose and emitter. I can vary the emitter volume and count to supply a sufficient amount of water for each different plant type.

The full rain drip irrigation system makes a very simple U shaped loop across the top of the square foot lattice and provides a dedicated drip irrigation garden feed to each square in the garden. I’ve come to appreciate simplicity in gardening as each time I’ve tried something complex, it seems to fail. Rainwater fills my collection tank and now provides daily water to my square foot garden through the rain drip irrigation system.

I tested my rain drip irrigation system with a simple garden hose and then installed permanent, underground piping to my square foot garden. I also installed a drain valve and a hose splitter at the garden hose bib for options in my garden drip irrigation system. I used the lattice boards from square foot gardening as a support for my master drip irrigation garden hose and then installed a dedicated feeder hose and emitter to each square. My rain drip irrigation is installed and working nicely with a timer controlling the daily watering times.



Raised Garden Beds and Square Foot Gardening

I’m moving from my deck container garden to a raised garden beds using the square foot gardening technique. I’ve had raised bed gardens in the past but used garden soil from a local organic gardener. I haven’t used these raised bed gardens in almost 5 years so I’m going to replace the top six inches with the specified square foot gardening soil mixture. The square foot gardening book was quite specific about the soil mixture and depth so I’m going to follow that approach to implementing my raised garden beds exactly.

I removed the years of weeds and top six inches of garden soil from my raised garden beds and saved the soil in a pile on the side. This is different and yet similar to the approach I used in my containers for my deck garden. This raised bed garden still has another six inches of soil and then six inches of river rocks and a drain pipe to help with drainage so that the soil does not get too moist. My raised bed gardens also have a water hose run to them and I will install my rain drip irrigation system when I’m finished.

A New Soil Mixture for the Raised Garden Beds

The soil mixture specified in square foot gardening was very specific – especially with respect to the compost variety for us in the raised garden beds. This is very different from my traditional approach using garden soil for my garden containers. I had to go to several stores to find all of the materials and the large amount of vermiculite was the toughest and most expensive to acquire. I also sacrificed an inexpensive tarp, as instructed in square foot gardening, for a place to perform my mixing of the 3 soil components instead of mixing it directly in the raised bed garden.

The compact packaging of the soil components expanded dramatically when I emptied them to prepare the soil mixture for the raised garden beds. Using the tarp helped a lot to preserve and use all of the square foot garden soil mixture in the raised bed garden. The mixture was surprisingly light as it consists of only peat moss, compost and vermiculite. It appeared very much like exactly what is in the little pots when you purchase plants from a nursery. It was a calm day and with a little water sprayed on the mixture, it was easy enough to mix thoroughly.

I filled the top six inches of my raised garden beds with the square foot soil mixture. I then added small divider rows to clearly mark out each square foot in my four foot by eight foot raised bed garden. I also went ahead and put in some support structures so that the taller plants in the middle of the raised bed vegetable garden will have something immediately to begin growing upwards on. Now we’re ready to plant seeds and young plants in the raised bed gardens.






Summary of Raised Garden Beds and Square Foot Gardening

Raised garden beds are ideal for implementing square foot garden techniques. I cleared the top six inches of old garden soil first. Then, I carefully mixed the specified square foot garden soil mixture on a tarp outside of the raised bed garden to insure that I got a thorough mixture. I refilled the raised bed vegetable garden with the new soil mixture, put in square foot marking grids and growth support structures for the tall and vine plants. Next, we’ll plant the seeds and young plants in the raised garden beds.
