High tunnel construction, part 4


We had an all-day rain last Sunday, as I mentioned in my last post. We were lucky in that we only got 1.6” of rain out of it. Other places in our area got upwards of 4”. I went for a walk Monday. The creek had not flooded, but I heard the sound of rushing water from the path and bushwhacked my way to the creek to find this little waterfall over a downed tree.

It was too soggy to work on the high tunnel Monday. We waited until the dew was off the grass on Tuesday. While I was puttering in the kitchen, I saw two deer far out in the field. I’m not sure what spooked them, but if it was me reaching for my camera, they have exceptionally good vision. They took off, followed by two more deer for a total of 4. They were not kind enough to pose together for a photo.

Our next step in high tunnel construction was, in Terry’s opinion, the most difficult. We had to put the header above the door. In the first step, we put in one post on each side, and Terry filled the hole with cement.

On Thursday, after the cement had cured, we put up the other post and the header. We followed the same procedure for the side post, except that it was not cemented in yet. We needed to have that post mobile until the header was in. To keep the post from moving, we put in two “jigs” that Terry made from two 2x4s. He marked the exact width of the doorway on the jig. We lined up the jig with the new post, checked that the jig was level and the post was square, and Terry screwed it in place. He then measured up the same distance on both sides and made a mark.

We put the second jig at the mark on both sides, made sure it was level, and the post was square.

Terry measured again and put a bracket on the posts on both sides to hold the header.

Now for the header. We put one end on a ladder on one side then lifted the other end to a ladder on the other side. We climbed up the ladders, trying not to bump our heads on the header (I was unsuccessful), and then, one side at a time, hoisted the beam on top of the bracket, where it was held in place by a clamp. Terry secured each side to the bracket.

And there we are!

More flowers are blooming all the time. My great white trillium (Trillium grandiflorum) is living up to its name.

Wild geranium is getting started, as are shooting star (my fav!) Jacob’s ladder, and moss phlox. (The phlox I just got from Jane is fall phlox, which as the name suggests will not flower until late summer/early fall.)

It’s hard to believe that May is almost over. The chicks will be coming soon. That’s always good for some excitement.

Hummingbirds, etc.


It is a soggy day here in northern Illinois. The radar shows a huge band of green all the way down to the Gulf of Mexico and heading straight north. Flooding is possible. Nothing we can do but watch and wait.
Our last episode mentioned a failed reproductive event for toads. Between Wednesday and Thursday, we got 1.4” of rain. The puddles filled again. On Friday, the froggies were a-courtin’ again. This time I heard the toads first, and the chorus frogs started up later in the day. As with the previous event, I saw only one female toad. I compared the two photographs. The male is definitely different. Last week’s male was almost black. This one is tan. I think the female’s markings are different as well. It would not surprise me if females only got one shot at it per year. Eggs are a big investment. This couple must have just been getting started. No eggs were in the water.

I noticed this year that the males find a place to elevate their head out of the water. Perhaps their song carries better that way.
Hey, Baby!

I took a walk to the south end of the property. I heard numerous toads and saw 6 males at one time. I saw some curled black threads in the water. I thought they were strings of black plastic that had unraveled from landscape cloth. I thought I’d better pick it up before it got wound around inside the mower. Imagine my surprise when it turned out to be eggs! Not toad eggs, though. In last week’s post, the toad eggs are larger, have a clearly visible, almost white vegetal pole, and are in a straight line. The vegetal pole of these eggs was only slightly lighter than the black animal pole (the difference is not visible in the picture), and the string is not straight.

Eggs close up
(Time out for embryology: amphibian eggs have a vegetal pole with a lot of yolk and an animal pole with less yolk. These two poles set down the body plan of the embryo. The yolk content slows cell division, so the cells that arise from the vegetal pole end up being larger and less numerous than the cells of the animal pole. All cells will eventually become part of the tadpole.) The only other frog I’ve heard is the chorus frog, so I’m guessing these are chorus frog eggs. I decide against raising tadpoles again.
We had a little setback on the high tunnel. On Tuesday, I helped Terry measure where the posts for the roll-up door needed to be. He drilled a hole…

And put in a stake.

As he puzzled through the directions for assembly, he noticed that the steel door posts were not pre-drilled. The posts needed A LOT of holes. He tried to drill the first two holes and failed. More equipment (a drill press with carbide bits) than we had at our disposal. New plan: use 4”x4” posts. He got some at Menards, and by Friday was making 16’ posts out of 9’ timbers. First he cut one off square.
Measuring for the door post

Then he patched the two together with plywood and metal.

Now “all” we have to do is get the posts and beam into place on each end.
Last Sunday, I saw an unfamiliar animal run across the field. I thought it was a fox. I watched to be sure it was not interested in our hens, which it was not. If it had been, I would have had to…what? Hit it with a stick? Anyway, it was very far away when I took this picture, but it was enough to positively identify it as a fox.

The white trilliums (trillia?) are blooming.

So is the red trillium. This is the first time I’ve remembered to check on it long enough to see the flower.

The wild ginger and geranium are duking it out next to the tractor shed. This is how a knock-down, drag-out fight looks in the plant world. It’s all about real estate.

The apple trees are started to bloom Friday, which was a nice, warm day for pollination. The tree was a-buzz as I took this picture. Saturday was windy and cold, which probably meant fewer pollinators. No bee in its right mind would be out today!

I saw my first hummingbird this week! I rushed right out with the feeder.

I saw a female a few days later.

Here’s the male resting on a stake in the lisianthus. So cute! How can a person feel glum looking at a hummingbird?

The jelly feeder has been crazy town with all the orioles. I love how the orioles slide down the pole to the food.

You might want to put your speakers on mute for the video. All you will hear is the fan from my oven.
And the rain comes down. We had an inch at lunchtime. Watch and wait. Perhaps another cup of tea. It’s that sort of day.

High tunnel construction, part 3


Terry has been busy this week putting in the rafter supports. After the first one, he learned to do as much assembly as possible on the ground. He prepared the horizontal piece by putting on three of the connectors.

He then hoisted this piece on top of a purlin and used a square to mark off exactly where the support had to be positioned.

Working on one end at a time, he installed a connector over the rafter. The two connectors allow the rafter support to move a little to reduce stress in heavy winds.He put tape over the connector to decrease wear on the covering.

In the center of the horizontal pipe, he put two angled pipes to finish the support assembly.

The migratory birds have returned. It is always like seeing old friends. The orchard orioles and Baltimore orioles vie for position at the jelly.

Here is an orchard oriole and a Baltimore oriole waiting for an opportunity at the jelly on the weather vane next to the feeder.

These two males are having a face-off on the ground. I saw two males fly at each other, fall from the air, and wrestle on the ground. It was all over before I could pick up my camera. It made me appreciate how awkward it is to fight with your feet.
What are YOU lookin' at?

Sometimes goldfinches line up for a turn at the sunflower seed feeder.

Hilda has seen as many as 5 rose-breasted grosbeaks on her feeder.

Three white-crowned sparrows have been hanging around. They will move farther north before long.

The red-bellied woodpecker is a strange jelly thief. His bill is so long that he can hardly get at the jelly, but there he is.
Oh, come on! That jelly is not for you!
You may recall that in my last post, we were worrying about flooding. I took a walk on Sunday and the chorus frogs and toads were making such a racket it almost hurt my ears. Here is a recording. The toads produce the long, single tone. The chorus frogs are usually described as sounding like a thumb dragged across a comb.


For all that noise, I only saw one female. There were lots of males. Here is the female, coupled with one male while a second male is trying to displace the first. A string of eggs is visible in the water. Sadly, after a few days, the puddle dried up. This reproductive effort was all for naught.

Also on Sunday, I saw bird I had never seen before. There were three of them. I was able to identify them as solitary sandpipers, even though they didn’t seem solitary at all.

I harvested rhubarb for the first pie of the season on Tuesday.

With the hens in summer quarters, I take a walk to the orchard every evening at dusk to close the coop. On Wednesday, I saw not only a beautiful sunset, but also the full moon rising.

We planted our potatoes yesterday. This was the first time we managed to get it done by Mothers’ Day. Terry furrowed the soil with the rototiller. I dropped the potatoes in; Hilda covered them, and I put down a marker. Good to have that done.

The tomatoes and onions are looking good. We have tentatively planned to plant onions on Wednesday.

I made caramel rolls for Hilda to celebrate Mothers’ Day.
Happy Mothers' Day!

We are getting some welcome rain today. It doesn’t take long to go from too wet to too dry. Hopefully, we will get the half inch that is predicted. The plants need it, and we need a rest day.
