After adding yet another five tomato plants to the greenhouse – we moved them around and reset up the irrigation system to handle the additional plants. The indeterminate tomatoes in large pots were moved to the ground so they have the most space to grow vertically. Vertical is the theme of the greenhouse. After watching a number of YouTube videos of other greenhouse enthusiasts I decided to give the string theory a try. We placed three wires across the greenhouse. Two along the sides and one in the centre. Then for all the plants that need support and will grow up a string (cucumbers, melons, and tomatoes) we attached jute strings that either connect with the wires or wrap directly above on the rafters.
The cucumbers seem quite happy to have the support of the string and the space to stretch out. The melons aren’t all large enough to even reach the string but in time hopefully they too will grasp the jute and head upward.
The tomatoes will apparently need coaxing to use the string. I almost feel like I can watch the tomatoes grow in the greenhouse. They have been very happy with the heat and the drip irrigation system. The top of the soil looks dry but the water has been flowing out the bottom of the pots when watered. The plants all look so healthy and happy so I am presuming that the roots are having to find the water deep in the pots which is making them that much healthier. They seem to all be standing a little bit taller with the string supports.
Happy healthy plants make for a happy healthy gardener. Another little experiment I am trying is to place milk jugs full of water in the greenhouse on the north side. The theory is that they heat up during the day and release that heat at night which will help keep the ambient temperature a bit warmer on our cool Alberta evenings. Though I read that I should paint them black – I went with motivational statements instead which make me happy regardless of whether or not they are doing their job.
Gardening is a series of learning moments. This jute string theory is yet another opportunity for me to grow.
