Making your world a greener place

Try to ignore the dirty window, the geranium that needs deadheading and the video-bombing chicken. Instead, notice the recycled plastic bottle which, when filled with water and placed upside down into the soil, slowly hydrates the plants in our window boxes by way of drip irrigation. We use these homemade irrigators in the tunnel and in the tire planters also. It prevents the stress on plants that happens when the soil becomes too dry which often happens in containers causing plants to wilt and become weak and stunted. As the bubbles go up, the water drips out.

There is more than one way to make drip irrigation bottles…

When placed above the soil and upside down as shown here, the bottle cap can be left on the bottle and holes drilled into the cap for the water to escape (this we do with larger mouthed bottles). If you notice the drilled holes become clogged from the soil, try enlarging the holes and/or perhaps put a few small pebbles mixed with fine sand in the hole just where the cap sits. Another option is to remove the cap completely (which we do with smaller mouthed bottles– around the size of a quarter or one euro coin size). With both these options, the flat end/bottom of the bottle can be left as is or it can be cut off. When cut off, it becomes easier to refill the water as the bottle never has to be removed from the soil. The downside to this is that it needs refilling* more often– the upside is that if it’s being used outside then it will collect rainwater. *Refilling the water bottles is a great chore for children.

Another option is to make several holes in the bottle itself and bury it in the ground right side up with just the pour spout above the ground surface. Refilling with water is done via the spout. This option may be more aesthetically pleasing but it takes up valuable root space in containers.

Glass bottles could also be used without cutting off the bottoms or having a cap on. Wouldn’t wine, vodka or gin bottles be pretty? Pretty dangerous with the winds we have here on the island me thinks– empty plastic bottles have blown out of their containers so make sure to bury them deep enough if you too live in an area that’s prone to strong winds. 😀 And I’m certainly not suggesting you start drinking that much booze, haha! 😉

So whether you’re looking for a little help around the garden, an inexpensive solution to water your precious garden plants while on holiday or are just a recycling zealot, this practice will help to keep your world a greener place.
