Insulating and Winterizing the Greenhouse

The temperatures are dropping, and it's time to get my new greenhouse ready for winter!  I'd be thrilled to keep my greenhouse above 55°F (13°C) for the plants that I want to keep in there, but I'd be fine with above 45°F (7°C) with our winter temperatures. We're using a space heater right now to heat the greenhouse, but in order to keep energy costs down, we want to insulate it the best we can.

After researching insulation techniques, here are the things that we did:

1. Insulate the inside with bubble wrap.

We're still working on bubble wrapping the entire thing - it takes awhile!  We used the kind with larger bubbles.


2. Place styrofoam insulation around lower half of the interior walls.

We have wooden walls on the bottom of our greenhouse.  We bought some styrofoam insulation, as well as supplemented with all the random pieces of styrofoam (and boxes of styrofoam bits) that we have been saving.


3.  Fill up large containers with water.

The water helps stabilize the temperatures.  During the day they will warm up, and at night they will release heat.  The more containers, the better!


4.  Stop air from leaking through.

We put foam weatherstripping around the door, since that is where a lot of heat escapes.  I also plan to make a weatherproof cushion to place at the base of the door outside, to further insulate the gap at the bottom of the door.  On the inside, we have a blanket pushed up against the door.


We realized that we had a lot of heat escaping from the foundation of the greenhouse, where the greenhouse meets the base that it sits on.  Since we had already put the styrofoam on the interior, we decided not to spray foam insulation into the cracks (and such ventilation is good in summer anyway.)  Instead we put salt marsh hay (this area's equivalent to pine straw) around the exterior.  It immediately made a difference and helped tremendously in keeping the greenhouse warm.


I do realize we've probably just invited all the mice in the area to come stay in our nice hay filled bed.  Mr. Red House says they'll add body heat and be of help.  I have my doubts about that and just hope that they don't do too much damage to my flower bed.  (My next order of business is looking into rodent repellants!)

The other option I've seen is to dig a trench next to the greenhouse and half bury sheets of styrofoam right next to the exterior for insulation.  After just building a wall around my shade garden, we were not keen on doing more digging, and a trench would disrupt my flower beds, so we decided against it.


I have to give a shout out to Mr. Red House for all his help with the sensors in the greenhouse.  As soon as I talked about wanting a greenhouse, he's been excited to integrate as much technology as he could in there.  One day, thanks to my technology-loving husband, I'm sure I will end up locked in my own house by an evil computer, but other than that I have to admit that technology is very useful. (Don't let Mr. Red House know I think that.)

The sensors Mr. Red House has put in the greenhouse have been immensely handy, as they feed information about the greenhouse status wirelessly to my phone and computer.  For all those techies out there, here is what we have:

top: Aeon Labs MultiSensor
bottom: Smart Sense Multi Sensor
The Aeon Labs MultiSensor senses temperature, humidity, motion, and light levels.  I have it placed next to my plants.

The Smart Sense Multi Sensor is placed near the greenhouse roof and detects when it opens or closes, as well as what the temperature is up near the roof.

The awesome Mr. Red House has also made a nice app displaying my greenhouse stats in real time.  Check it out at the bottom of my blog page!

Our greenhouse is coming along pretty well, but I know temperatures will be even colder in a couple months.  If anyone has other ideas about how to insulate greenhouses, I'd love to hear them!

Fall Projects

Another season, another project here at the Red House Garden!
This fall we decided to tackle an awkward part of the yard - a back corner of the house where the yard slopes.  In order to help this area be less ugly and more usable, we chose to put in a low retaining wall. 


Thanks to interlocking stones available nowadays, this project only took a couple of weekends.  The hardest part was digging and laying the first layer of stones so that they were level.


A bunch of sand, interlocking stones, capstones, landscape adhesive, and two weary backs later...


Ta da!
What was previously an awkward, weedy corner of the house is now going to be my shade garden.


Now I have the winter to think about how to landscape this area - though I couldn't resist browsing for my new garden at the local nursery's end of the season sale.  We found a Weeping Canadian Hemlock and a 'Waterfall' Japanese Maple that just insisted on coming home with us and being planted in the new garden.

Fall is a busy season in the garden.  In addition to the rock wall, we are also working to complete our other autumn tasks: bulb planting, garden cleanup, and insulating our new greenhouse


For as we all know, winter is coming...
and there is only so much more time before the snow hits up here in New England!

A Strange Mist Hath Appeared

You might think it was mist floating around my stone bench this Halloween.


But no, 
it's not mist.  
It's no decoration for Halloween.

Anyone want to hazard a guess?


I'll give you a clue - it's plant material of some sort.


My stone garden bench sits near my retention pond, in which there is a good sized clump of cattails growing.  The abundance of whiteness next to my bench is what is probably 
millions 
and millions
of cattail seeds.


They had some help getting there.


If you can imagine two little girls throwing cattail seeds up in the air, making it 'snow', sometimes to the tune of the movie Frozen's 'Let It Go', you will have a good picture of what went on here.


Next year we might have a larger clump of cattails.
Like a whole field of them.

My kids are going to have a ball.
