Deep Watering – PVC Pipe For Your Garden Plot

Did you know? Volume of a deep watering pipe is simple to calculate.Volume calculator
Formula is V = πr2h
Volume = pi X radius squared X height

deep-pipe-watering Use a 12 to 18 inch 2 or 3 inch PVC pipe with a few holes drilled down it’s side(s) makes watering individual plants fast and easy.
Deep_Pipe_Watering2 You may want to paint the part of the pipe not in ground to make it less visible in your garden.

Consider gluing a 2 liter soda bottle (with a hole or bottom cut off) to your pipe so you can (1) See when your deep pipe water pipe needs refilled (2) and to allow you to go a few days between filling your deep watering pipe.
Hint I used a product called Plumbing contact adhesive and sealant. It dries in about 24 hours being clear, hard and provided a leak proof attachment of a soda bottle to a 18 inch piece of PVC pipe.

Using a pipe is very effective and well suited for gardens, small farms, and remote landscaping and forestry projects. Deep pipe irrigation is commonly done with 1″ to 3″ diameter vertical pipe placed 12-18″ deep into the soil under or near the crop plant or tree.
The top of the pipe can be covered with a cap or a screen disk to keep trash and insects out of your water pipe.
A series of small holes should be drilled in the side of the pipe near the plant if a seed is used or if a small transplant with roots shorter than the pipe is planted. The seed or seedling should be fairly close to the pipe (1-3 inches for a young plant).

In some cases, deep pipe irrigation is better than surface or buried drip systems. First, it can be used with low quality, low pressure water and low technology. Second, even in areas where the materials and technology for drip systems are available the deep pipe system provides the benefits of buried drip, greater water use efficiency (due to reduced evaporation) and weed control; but the surface mounted deep delivery drip systems can be monitored and repaired much more easily. Finally, the pipes can be collected at the end of the season for full field / garden plot tillage.

It seems that cutting the top off (What was the bottom of your soda bottle) of the bottle and filling while in place next to the plant it works well for tomato cucumber, squash and other garden plants. Not free but a cheap long term garden investment.

  1. Hi – do you leave the bottom of the pipe open? I was wondering if I should block the bottom so the tube stays fuller for longer & water can drip through some of the higher holes.

    • My soil is a heavy clay base soil and I do not cap the under ground end of the pipe.
      However if your soil is sand or loom based you may want to cap your irrigation pipe. Do Not glue the cap to your pipe, at the end of your growing season you will most likely need to clean plant roots from your inside the pipe and having a removable cap will be helpful.

  8. I’ve been using both systems; I’ll cut some holes in the sides of the pipes now. I fill up the inverted bottles with irregular pebbles so they keep their shape when buried and don’t get packed with clay over time.
