Absolutely beautiful, sunny and almost 13 C at my location and against the house it was even much warmer than that and felt almost hot as I sat on the veranda transplanting house plants and seedlings and wishing late winter / early spring could always be this way ... heck, it feels like mid April! There were bugs, flies and spiders doing their thing and geese squawking at the nearby lake where open water always remains due to aeration. I untied some of the cedars and junipers I keep wrapped during the winter to guard against deer wanting to eat them. I figure with the snow having mostly melted off the fields, the deer will be grazing upon last years grasses instead.
Prairie_northrose, most plants that come up early in the spring are very resistant to frost, so I wouldn't go and be worrying too much about them, though let's hope we don't see a blast of -20 C. As for watering, I'm sure they'll be fine for the time being until spring advances and really heats up.

At this point, the Weather Network is calling for Edmonton to hit 18 C next weekend.

I think you're right about leaving things be and then watering when needed. Myself, I would be really leery of weather like this. I'd absolutely love to have it, but it always seems that worse weather will follow and create havoc with plants that thought spring was coming (and with you, who thought spring was here!). As Terry says, just hope that it doesn't get too cold!

Enjoy!

My daffodils are up and budded on the north side of the house, the crocuses are starting to bloom and I saw a honey bee out and about yesterday. This is crazy early, even for down here in the chinook belt. The tulips are also making an appearance in my south facing beds and the blue butterfly delphiniums are sending up little shoots. All my beds are mulched with shredded cedar chips in an effort to combat the drying winds and wild temperature fluctuations we experience here and other than that I don`t do anything.

Thank you Tworsz, Marcia and Shillanorth for the sound advice. I am fortunate to have found these forums.

The weather sure keeps things interesting! I do feel like it is quite a feat to grow anything in such unpredictable temperatures, the fluctuations can certainly be extreme. It really is dry right now. I am grateful to have such warm temperatures and a mild winter so far, especially compared to the one last year.
