As the years passed and the holidays continued we tried numerous techniques, each of which was relatively simple. Some worked, while others made for a bitter surprise upon our return.
Here are some of the more effective irrigation tricks we’ve tested over time which will ensure your indoor plants remain fresh and flourishing while you’re away.
Plastic bottles
This technique is one of the most common, and consists of filling two-litre plastic bottles with water, and making a hole in the lid and at the base of each bottle. The bottles are then planted in the soil at the neck. This way, the water is slowly released and the plant can enjoy consistent moisture for around two to three days. Recently introduced to the market are water spikes, a device which attaches to the end of the water bottle to aid the slow release of water and make it easier to insert the bottle into the soil. The rate at which the water is released is around a litre per hour, but can be reduced by placing some sand in the neck of the bottle.
Strips of fabric
To apply this system, fill a large bucket with water and place it near the plants you want to water. It’s important to position the bucket above the plants, otherwise this technique won’t be effective. You will need to prepare strips of fabric (preferably cotton) long enough to extend from the base of the bucket down to the pot, allowing for a couple of centimetres to be buried below the surface of the soil. This method relies on the capillary action of the cloth, guaranteeing moisture for seven to ten days.
Water storing crystals
These products are capable of storing a quantity of water up to 400 times their weight, and gradually releasing it into the soil. They contain molecules which grow as they absorb liquid. When in contact with soil, the molecules decompose and slowly release the water. The effect is similar to that of a drip irrigation system and, depending on the amount used, this product can keep your plants watered for ten to fourteen days.
Drip irrigation system
If you will be away for over a fortnight, you will require a reliable system which will ensure a more systematic irrigation. In the end, my family decided to install a very simple drip irrigation system at the time of our departure. I suggest that you gather the plants you wish to water outside, protected from direct sunlight and close to a tap. The irrigation pipe must be long enough that the drippers reach all of the plants. The number of drippers depends on the size of the pots; the larger the pot, the more drippers it will require. Using a simple control unit you can regulate how long the plants are watered each day. I strongly advise that you trial the system before you go away, to make sure that everything works as it should.
And lastly, I leave you with one piece of advice: treat your neighbours and friends well and you may be able to ask them to pop over every now and again while you’re away to check that your plants are healthy and happy!
