Strawberries and old piping.
I need to try this.
In general, strawberries are planted from August through November. If you expose the strawberries to sunny days and cool nights they will be more flavorful. Strawberries are well-suited to growth in containers such as strawberry jars, barrels and grow bags, and the plants will adapt to less-conventional planters such as PVC pipes. Such containers are a good option for homes without the space for a garden or with unsuitable soils, such as heavy clay. To build a planter from PVC you will need the following materials: an electric drill with a hole cutting bit that will cut a 5 – 7cm hole, a 2 or 3mm drillbit for the watering pipe, a length of PVC downpipe 100mm or 150mm diameter, end cap for the downpipe, a narrower diameter (15mm or thereabouts) length of downpipe for watering. Make it about 8 – 10cm longer than the downpipe. If you have a pressurized irrigation system, you can use a length of soak hose instead, a cork, a knife, duct tape, a length of geotextile (or hessian would do) for wrapping the watering pipe, twine for tying the fabric to the watering tube, good fertile soil, 1 liter or so of gravel, strawberry plant, a few companion plants (nasturtiums or marigolds), a large tub or box (to stand unit in whilst filling), fixing collar or ties.
Decide on length of unit and cut the tower tube and watering tube accordingly. Make the watering tube 8-10cm longer. Drill vents holes in watering tube. If you put holes all the way down the upper planter won’t get quite enough water. Cut the geotextile or hessian to the shape that will cover the holes in the watering pipe. Then carefully with a knife, whittle down the cork til it fits the end of the watering tube. Now seal it off with duct tape. Cut the holes in the tower tub. Place the large container against the wall. Place end cap over the base of the tube. Insert watering tube then fill the bottom 10 cm with coarse gravel. For the lowest hole I recommend planting a companion, less incentive for pests to climb up. If you are using stoloniferous varieties you can leave a few gaps in the lower holes.
