Benches in the Greenhouse

Lars and Jeff spent the day building benches for inside the greenhouse, so that we can start moving plants, grape cuttings and vegetable seedlings outside.

The assembly had to take place inside the greenhouse, since the door is rather narrow - the challenge of course was the fact that they were surrounded by glass :)  Nothing happened though, they did great.

Each bench is over 11 ft. long, and has two levels, plus space underneath.  So far, the only plants we moved out were our geraniums, which we overwintered in the cellar (all 50+ survived)

Firewood Clean-up

Cleaning up the future driveway continues, now that the snow melted somewhat.  Zach came to visit this weekend and chainsawed the large tree trunks into firewood pieces.  Lars and Tina could hardly keep up with moving the cut wood and stacking up the brush pieces onto a nice pile for burning later.

Grape Vine Cuttings

We sacrificed our nice dining room to turn it into a makeshift greenhouse, since our "real" greenhouse is not warm enough yet. We set up two folding tables under the windows, plugged in a 10 ft plant heating mat, and then set out the starter boxes.  The heat below the boxes (which are placed on a special metal grate) raises the soil temperature to optimal levels for root development.

With the nicer weather, Jeff has been pruning grape vines, and he uses the better shoots for starting new vines.  We keep 4 buds per shoot, dip it into plant rooting hormone, and the push each shoot into its own little soil filled tube.

So far, we have about 300 cuttings:

Late March Snow Day

What else is there to do when a late winter storm dumps 7 inches of snow?  "Play in the greenhouse of course!"  Jeff spent a good part of this afternoon filling our paper tubes with potting soil, which is specially formulated for starting seeds and plants.  Getting ready to start some grapes from cuttings ... any day now.

Starting Vines from Cuttings - An Experiment

Last year we had purchased a small grape starting kit at a trade show - it contained paper tubes, filled with dry starter soil and a crate covered with plastic. We had never done this before, but we did take  late cuttings off some concord grapes, and out of the 75 plants we started, about 50 were alive and well by the fall.  (Not so sure if they will make it through this rough winter - we'll have to see).  This was not such a difficult task, so our plan is to try the grape propagation on a larger scale.  There is a lot of detailed information available on the internet, here is one of the useful sites.

Over the winter we started collecting the cardboard tubes inside paper towels, toilet paper and gift wrap (friends and family helped with this project).  This weekend, Jeff and Sam assembled our starter boxes:  they used flats that usually hold berry boxes, lined them with heavy plastic, and then stuck the paper tubes as close as possible into the flats.  Turns out that each flat holds about 90 of these tubes.  They filled up a lot of boxes, with enough tubes for about 800 cuttings!

Jeff then found a plastic jar with an opening that was just right to fit inside the paper tubes - it was a honey container, which he "transformed" into a scoop.  Once we are ready, we'll moisten the potting soil and then fill up each tube, and a perfect cutting from the "mother" grape vine will be dipped in rooting hormone, and then placed in the tube for growing.  The point of the tubes is to maintain the fine roots, and not to get them tangled up between different vines.

For the first few weeks, we will keep the flats with cuttings on a heating mat inside the house, but as soon as the first leaves emerge, we'll move the boxes into the greenhouse. The greenhouse is nearly ready, and even without a heater in it, it seems to reach a temperature between 40° - 50° F during sunny days.  We still need to build benches and run a waterline/hose.  As soon as it gets a bit warmer, we will move barrels into the greenhouse and fill them with water to maintain a more constant temperature.
