Milk bottle deep watering system
Use a 2-litre milk bottle and drill a row of 4 holes on the two opposite sides of the milk bottle – so you end up with 8 holes altogether.
Place this milk bottle in the centre of your bed with only its top sticking out.
Fill the bottle with water and replace the lid back on, and the water will slowly water the roots of the plants, without any waste. Fill your bottle with water once a week or more often in dry and hot weather, and you will save quite a bit of water on the long run, especially during water cuts during droughts.
I have made the holes a bit bigger to show up clearly in the photo, but make your holes much smaller so when the lid has been replaced, the water comes out much slower then.
The 2-litre bottle with it’s handle, makes an ideal and light watering-can for watering seedlings when very tiny holes are drilled in the bottom of it. An electric drill is the best option to use, or use a thick sewing needle under the flame of a burning candle. Stick the needle in a potato (or a biggish cork) as a “holder’ so your fingers won’t burn as the needle becomes quite hot!
This watering milk bottle placed in the middle of the bed, works very well in raised 1m diameter circle beds as the surrounding plants get watered as well by this method of deep watering.
Placing these milk bottles next to small trees to water the trees, makes for easy watering and save water that way too as the water will go straight to the roots of the trees.
