I am planning on installing a drip system this spring. I had extensive drip systems in AZ when I lived there, but this is a first for me where it gets very cold all winter. Do you have to blow out the lines in the fall and winterize? I'm worried about antifreeze getting into the soil if I have to use it. Any help would be greatly appreciated!
Brenda, I don't have a drip system but I believe they must be turned off and drained in the winter or lines fill with ice, expand and break. Perhaps the technology has improved. I would talk to someone who sells or installs them in your area.
My understanding is to disconnect from the water, drain and/or blow out in fall. No antifreeze or the like needed. I was told the soaker hoses don't need this as they are so porous (and are all I have at the moment).
We disconnect, drain and blow out our swamp cooler water line every fall and it does fine exposed out on the north side of the house & roof. I would imagine that an irrigation system in or on the ground should be fine with this treatment too.
I know this is an old thread, but I just found it so I'll talk a bit about my 24 year old drip system. My drip system is huge - the main pipe goes around almost the entire acre and has thousands of drippers and micro sprayers on it. There are several drain valves located at the low points of the main pipe which are opened up and left open to drain all winter.
Hi Tabby, thanks for your input. I just posted a message to you on the Rocky Mountain Forum. I installed my drip system last summer, and it made it through the winter just fine. I'd love to see some pics of your place... we used to have over 50 roses when we lived in AZ. We bought two roses here last year, and surprisingly they did not make it through the winter. The folks at our local nursery, where we bought them (and they are a super family owned nursery with excellent products) said that they themselves lost 7 thirteen year old roses that they had at their home this year. Apparently, the -20 degree temps were to blame.
I don't think I lost any roses, but they cane damage was the worst I've ever seen. I have a lot of hardy old garden roses and some of them died to the ground, which they'd never done before. I winter watered them, but I don't think it was enough.
On the other hand, the irises are spectacular right now.
