Drip irrigation watering time
I have installed a Gardena micro-drip irrigation system as well as
below ground drip irrigation line for lawn, borders and pots. My question relates to watering rates for pots. The system for pots has drip heads which deliver 4 litres per hour, although I tested a couple and they seem to go up to 6 litres per hour. I have some medium/largish pots around 40 cm square and 30 to 50 cm high with photinia, ceanothus, bay and similar. What rate of watering or length of time watering using the drip heads does anyone use or recommend? Currently I have them on one hour in morning and one in evening - but they seem to be leaking quite a lot and I wonder if this is too much. I understand that the answer varies according to plant species, site, container etc, but I wonder if anyone has any broad recommendations for this system? |

I understand that the answer varies according to plant species, site, container etc, but I wonder if anyone has any broad recommendations for this system? The nursery I used to work for http://www.blakeneyhouse.co.uk/ we used 4lph drippers and as a rough guide had one dripper per 10 litres of pot. On hot days we'd run the system for 15 mins in the morning and 15 mins in the afternoon. The trouble with leakage gets much worse if the compost totally dries out. It's difficult to re-wet the compost and expand it to fit the pot again. Little and often seems way better than one big hit a day. I proposed a timer to water at dawn and dusk to cut down on evap but it was never done... The worst wastage was from unused drippers. No on / off tap on individual drippers.

I have ten inch pots with one tomato plant in each - I have mine on for two hours a day - seems about right - there is always a small amount of excess water which has drained through at the end of the watering period. |

I think it's probably way too much - think about how much you might apply if using a watering can?. I don't remember precisely, as we've moved and aren't using it any more, but I think we used to run our system for about 10 minutes 3 times a day. you need to find a nice warm dry week or so to test it properly. But I'd probably start at 15 minutes each time. -- Chris French |

You must surely have drippers feeding a lot less water, at 4l per hour that'd be best part of a watering can full of water per plant per day -- Chris French |
