Garden Enclosure "Greenhouse" Construction

Our garden is progressing nicely. We’ve built a greenhouse to keep pests away and are in the process of planting now. So far, have red and bell peppers, celery, broccoli, tomatoes, several types of beans, peas, beet root and okra started… SO looking forward to them yielding bounty!

Occasionally arranging helpers yet, after a poor experience with the Dutch couple as they were separating while here (come to find out) and the girl was a militant vegan who ate us out of house and home. Not a good experience — but they’re gone. A Parisian engineer guy is due this Friday (wish us luck!)

The garden cover is constructed of 1 1/2 inch irrigation pipe cut, arched, then stuck on the end of galvanised 1.5 meter steel pipe which are driven half way into the ground. The baling twine helps hold it all in place and makes it quite rigid then the electric fence wire rope keeps it strong and durable.

The planters are made from 1000 litre fluid totes (or IBCs) which have been washed. The black ones are near new and carried saline water for water purification (so no worries with nasties!) I measure and marke them before using my angle grinder to cut them in half. Seems they go a treat on hot days but are harder to cut when its cool. In the bottom of each (after all opening have been siliconed shut and water tight) I lay 7.5 meters of socked slotted agie pipe (use typically for wastewater drains). These are spun in circles, a filler neck fitted, and zip tied in place. Then the all important drainage holes are drilled about 150mm (or leaving about 150 litres of water in the tank AND overflow holes near the filler (in case it floods, the planters need to shed the excess water). Then, about two wheel barrows full of sand, then a layer of sugar cane mulch (to keep the nutrients from the soil and plants for making the water cavity down below to acidic from fermentation), and finally the top layer of two or so wheel barrows full of topsoil. They are quite a lot of work — yet conserve 80% of the water of usual in ground gardening, they make tending to them easier as they are raised, reduce the amount of weeds, and keep plants in their designated spots with out effort. Each should last for many years and only occasionally need to be refreshed soil wise and weekly water top-ups with a hose.
