Winter Arrives

This weekend brought us our first real proof of winter in St. Louis, mild temperatures driven out as the Arctic air pushed in.


I did not venture outdoors into the 10ºF (-12ºC) garden, but instead chose to use the long lens to show you what these temperatures mean to me from indoors. The water barrel in the front yard has a birdbath heater in it so stays iceless -- the edge gets so frosty though!

What follows the rain?

Eleven inches (28cm) of rain this month in St. Louis (officially), with at least 9" (23cm) of it coming in the last four days. What follows heavy rains in late December?


Well, two things. The first is fungus, or at least fungal blooms. My wife noticed these crazy orange/reddish things from the window.

Mild?

I've been hearing that this winter in the Midwest (remember that I'm in St. Louis) has a high probability of being a mild one. As a zone 6 bamboo grower I hope for a mild winter every year, as it's important for the plants to keep their green leaves in order to have any chance of a "size up" next year -- meaning larger, taller culms emerging in spring.


The last two winters were tough on bamboo here. Two winters ago was the worst, when all of my plants defoliated -- you can see the results in the image above. At -8ºF (-22ºC) I was literally one or two degrees away from "topkill", where even the culms are killed -- probably the worst-case scenario for bamboo lovers. The winter before that (which would have been 2012-2013) was quite mild though -- is this what I should expect for 2015-2016?

Indoors, in a hurry

Although the freezing temperatures won't arrive until tonight, I brought in all of my tender plants yesterday. As usual, this was before I really had a place to put them all.


I brought them in a day early (at lunchtime) because we were expecting rain in the afternoon, and many of these plants would not be nearly as happy sitting in a cold garage in wet soil. Plus they're easier to move when dry -- much lighter!

More results of freeze

I started looking at the results of our recent first freeze in yesterday's post, showing the beauty in the big leaves now dead.



Today it's less pretty, showing some of the more interesting observations of a post-freezing night.

Beauty, from first freeze

We had our first freeze in the St. Louis area a few nights ago, which means that lots of tender plants get turned instantly ugly.


That's upon first glance. When you look more closely there's actually quite a bit of beauty, especially in the large, freshly-killed leaves of bananas, cannas, and Colocasia.

One-word Wednesday: Frost!

pond ice art

Nor surprisingly, the pond has built up a layer of ice. A few days ago when it was still forming the sun was out and the frozen pond in sunlight is irresistible to me.


Last year I had just a lifeless sheet of frozen water to photograph. This year though there's a biosystem under the ice, and that makes it so much more interesting.

Ice returns briefly

This first winter with a pond in the garden, I'm getting the idea that I'll never be short of photographic subjects again.



The pond was thickly iced just recently, but then warm weather and rain melted it completely, and now it's frozen again. Over the next few days it should melt again, with temps into the 40's F every day this week.

pond meet ice, ice meet foot

A brief taste of winter before the unseasonable warmth returns -- it's been quite cold the last few days.


So cold that the pond is frozen. Not just pretty to photograph ice like last time either, this is thick, solid ice. I really want to walk across it. Really.

By the Bucket

After shutting down the stream due to sub-freezing weather returning, I noticed that a water-filled bucket had frozen over again. This was not surprising.


What was surprising was how very pretty the ice was.

The stream in winter

When I added the artificial "stream" water feature to my garden in 2006, I immediately fell in love with the atmosphere it created. Its quiet, bubbly voice made a big impact, adding a calmness to the patio area that I never would have thought possible. It became so integral to the surroundings that when its first winter came around I did whatever I could to keep that water flowing.


I remember bringing buckets of hot water out there on cold evenings, hoping to keep the stream temperature above freezing for the night.

Frost Flowers, another day

The other morning I posted about frost flowers, delicate ice structures that are produced by certain types of plants under certain freezing conditions. In that post I questioned the conditions under which these glacial garden blossoms formed.


I've gotten some more data (there are new frost flowers in my yard), so I'm taking another look.

Frost Flowers

This morning I headed outside with the camera, as I was heading over to the community mulch pile to pick up a load of mulch. It was a frosty morning, a degree or two below freezing. I only walked out of the garage for a moment, but something caught my eye -- an interesting flash of white:


I wasn't expecting it, but some of the scarlet sage (Salvia coccinea) plants that I grow as an annual throughout my yard had produced frost flowers!

Cold kills the plants

After our hard freeze Friday night (25ºF), most of the annuals and non-hardy perennials saw their brief lives end. Saturday I took a walk around -- after it warmed up a bit -- and surveyed the damage.


It wasn't pretty. Go to bed with green leaves, wake up to brown.

Scrambling because of the cold

Friday evening it was forecast to get down to 25ºF (it did reach that) so before it got dark I had a lot of work to do. Although our normal low for this time of year is about 40ºF, our temperatures are not steady. A dip down to 25 isn't record setting, nor is it common. It does mean that I had to figure out how to protect a lot of plants a few weeks earlier than I should have.


The quick solution was to just put them all into the garage for the night, as it will warm up again in a couple of days.

Too cold, too early!

This morning when I woke up it was 24º F. Our normal low for this time of year is 40º F. I knew the cold was coming, but it's still a bit of a shock. So is it winter already? It feels and somewhat looks like a winter sunrise...


Nope, there are still some leaves on the trees. Plus the high temp over the next few days will be upper 60's F, with lows ranging from normal (40º F) to 50º F. For those of you who garden in areas of the country with predictable, regular temperatures and weather I envy you.

Nobody except the homeless feels these early below-freezing nights more keenly than gardeners, because it means the instant, overnight death of many plants that we have nurtured for the past half year or so. It also means scrambling to protect plants that we don't want to see die yet.

I'll tell you about my scrambles in tomorrow's post.*** .
