Version 3.1 is under construction with a couple of key changes. Version 1.0 was made with 2″ PVC (too small in diameter but close to being tall enough). The slots for planting were drilled with a hole saw. I shredded my fingers while planting the crowns because I failed to sand the rough edges. The density was very good but it was a challenge to keep them properly watered. Check out the start of my strawberry tower experiments here.
I toyed with, played around with…………poor choice of words…..I am always wanting to improve on the prior efforts so I have modified V 1.0 and V 2.0 and then V 3.0 ……. 3.0 was not well thought out and the added pockets on the short towers were not well spaced out. They were crowded, impinged upon the others and looked ugly….but the berries grew pretty well.
With V 3.1 I started with 3″ PVC drain pipe and I chose the version that created pockets rather than drilled holes. I spaced them a little closer and arranged them in a logical and orderly fashion. I should be able to get 28 plants in a space that would have held 2-3 plants in a matted row system and much easier for an old guy to harvest without bending over.
The photos below show the construction process. Some time soon I will fill the pockets!
I left a space of 12″ at the top for a water reservoir above the first pocket. I space the remaining slots at 9″ vertically between pockets. I snapped another snapped line at about 90 degrees left and right. The pockets were staggered to better spread out the plants.
I use a paint stripper to heat up the plastic above the cut slot in order to shape the pockets.
I keep a leather glove on the hand that I use to shape the softened plastic PVC.
There is a blank space at the bottom. I use a post hole digger and plant the tower about 12 inches deep for stability.
