Quote: We use an automatic waterer here. Most of the hose is now under roughly 4 to 6 inches of concrete. But there is still some of the hose that is exposed to the elements. Still when the temps really dip down into the low 20"s, I have to carry the birds water from the house. When the temps are that low we normally have shut the water off at the house, and have covered the hose bib already. So for the few days that are very very cold, it simply means more work for me. But I find that it's much easier to remember for the couple of super cold days, than it is for me to remember day in and day out.
A hose that is buried even an inch or two is going to be protected enough for most days here in Western Washington. There maybe micro climates where this isn't enough. But if you live in one of those MC's you should know by now that you may have to consider that fact. I am a King County native, and I have yet to be proven completely wrong about caring for water pipes around here.
We do protect our faucets when the temps are lower than 27 to 25 degrees for any length of time. Where I am I don't worry about overnight temps until about they dip below the previous noted range. We get cold fairly early in the winter here, because of living so close to one of the gap in the Cascades, and on a Plateau. But even most my hanging baskets manage short dips in overnight temperatures. The baskets are semi protected under the eves of the house.
I have also managed to winter over many plants in the very small greenhouse. I don't add any heat the GH until, we have extended freezing temps that are below roughly the 27 to 25 range. So far I haven't lost anything, that wasn't truly tropical. I did learn the hard way that Anthuriums do not like to get cold at night. My poor plant has suffered a lot this summer. I am planning on bringing it back into the kitchen soon. It will not handle anything close to freezing.
We also have found that when things are cold enough that we have carry water for the chickens, that we also have to keep the hummingbird feeder thawed. We now have year around hummers, so we are now feeding them through out the entire year. I am certain that I didn't cause the problem, but I am now trying to make sure that these little birds will survive our winters here. They used to migrate. Still I just couldn't bring myself to ignore the nasty little buzzards during a blizzard.
