An automatic watering and feeding system will take the strain out of watering plants and crops for you this summer. Simply set it up and top up the reservoir every few weeks – adding some liquid feed at the same time – and you can sit back and watch your garden grow, or go on holiday, safe in the knowledge that your plants won’t go thirsty.

Fill up the tank with tap water. It’s a good idea to add a suitable liquid plant feed to the tank as well, so that your crops will be watered and fed at the same time.

Keep the tray and valve clean so the watering system works well. If any dirt falls in, wash the tray, valve and mats thoroughly before replacing the pots.
