In order to grow tomatoes in a tunnel, we have to be able to get inside with tractors to till and to make raised beds. The ends of the tunnel are made to be removable and the sides are tall to accommodate our equipment. The beds are raised and covered with plastic for warmth, weed control, disease control and moisture conservation.
Below is a slideshow to see how we do this (click play button on right side of picture to start)
Preperation
We take the end off and use a tractor/tiller to prep the soil
The ends are removable to allow access
We get everything tilled up fine
The finer the seedbed, the better the beds get shaped
a fair amount of water needs to be applied to the soil
Once the soil is prepared we are ready to make beds
We have a bed shaper/mulch layer we use to make beds
Things are tight, no extra room to spare
In order to get five rows inside, the margin of error is just a few inches
The second pass is a little better as the tractor is away from the structure
We back down so we only have to take off one end of the building
The shaper makes a raised bed...
And covers it with plastic to control weeds
The plastic conserves moisture too
Getting the machine in the ground at the start is tricky
Once going you can't really stop or slow down
The last pass is very close to the wall, hopefully we have enough room!
The ends get neatened up by hand
Under the plastic is irrigation tape, which delivers water to the plants
The headland gets smoothed out...
before the endwall can go back up
Always a satisfying feeling to get it to look like this
Endwall back up, ready to plant tomatoes!
