{{ {{tntn|Introduction}}
|Introduction==Acknowledgements=
The landscape is quite steep at Lake Bunyonyi Ecovillage. Thus, planting in terraces requires important effort to work the ground for potato plantation. Moreover, potato harvesting is also work-intensive as one must dig out the potatoes from the ground. On top of that, the gardens are quite far from the kitchen which adds some effort to the process between collecting and transporting before preparing the food. Finally, the available place between the houses of the ecovillage is limited.
=Our solution and its expectable benefits=
Use locally-available material, simple technics and tools to build Potato Towers to:
*Harvest a high yield of potatoes on a very limited surface,
*Lower potato watering effort (if needed),
*Lower potato harvesting effort,
*Bring foods closer to the kitchen,
*Inspire people through attractive green design.

{{ {{tntn|Tuto Step}}
|Step_Title=Gather construction material
|Step_Content=#Select sturdy eucalyptus tree trunks for poles,
#Use the panga to cut down the trunks,
#Use the panga to remove the branches from the poles,
#Collect the branches to later use them as flexible wood sticks,
#Use the panga to cut the trunks into poles,
#Collect banana leaves,
#Collect stones,
#Collect nine sticks,
#If possible, already collect mulching material (corn stalks, rice hulls, hay, straw, dry leaves, BRF …);
{{Info|Our poles were approximately 4 feet \ 1m20 high and 4” \ 10 cm thick.}}
{{Info|The wood was harvested directly on the compound. Indeed, the compound integrates parcels dedicated to eucalyptus forestry. Eucalyptus is used for construction (hard wood), firewood, charcoal and as medicinal plant.}}
{{Info|Apparently, if one cuts down a eucalyptus, the tree grows a new trunk.}}
{{Info|If you did not collect enough wood sticks, you can later gather more branches and/or use other available material as flexible wood sticks.}}
{{Info|If you did not collect enough banana leaves, you can later gather more leaves and/or use other available material as envelope.}}
{{Info|We describe the procedure as implemented at Lake Bunyonyi; please feel free to adapt in accordance with your environment!}}

{{ {{tntn|Tuto Step}}
|Step_Title=Prepare the location
|Step_Content=#If necessary, make the location flat before you install the potato tower,
#Place one of the collected stick at the center of the location,
#Insert the stick in the ground,
#Define the position of the poles around the stick (circle):
##Attach the rope to the stick,
##Extend the rope 1 to 2 feet \ 0,3 to 0,6 m from the stick,
##Place one of the collected stick at the end of the rope,
##Keep the 1 to 2 feet \ 0,3 to 0,6 m from the stick with the rope and move 1/8-turn around the central stick,
##Place one of the collected stick at the end of the rope,
##Repeat six times (one for each remaining pole),
##Remove the central stick,
##Stow the rope;
{{Info|Lake Bunyonyi Ecovillage has many slopes. We built a first structure to have a flat location (see picture).}}
{{Info|Those steps are really for the aesthetics. The rope allows you to have a circle shape. We did not do it.}}

#Select a stick,
#Remove the stick from the ground,
#Use the spear to dig a one-feet \ 30-cm deep hole where the stick was,
#Install the pole inside the hole,
#Fill the hole with stones and the soil / dirt you removed,
#Repeat seven times (one for each remaining pole);

|Step_Content={{Dont|Do NOT let uncovered spaces around the potato tower. Even though potato leaves love the sun, the potatoes themselves might not be edible if the potatoes are in direct contact with the sun. Make sure that your banana leave envelope fills the gaps around the potato tower.}}
{{Dont|Do NOT always add potatoes on top of each other in the different layers. Potatoes will use the space available for them to grow. If you plant them one on top of each other, you might limit their development and size. On each layer, alternate the spot where you plant the potato eyes.}}
#Add stones in the center of the potato tower,
#Add a layer of banana leaves inside the structure of the potato tower,
#If necessary, mix the soil and the compost,
#Add the mix in the structure of the potato tower, between the banana leaves and the stones,
#Add the potato eyes:
##Add two or three potato eyes approximately 4” \ 10 cm from the outer part of the potato tower (from the banana leaves),
##Repeat approximately 8” \ 20 cm from the previous plantation spot,
##Repeat until you complete the circle;
#Repeat the two steps above until you reach the top of the banana leaves on this layer,
#Repeat steps above until you reach the top of the potato tower;
{{Info|Stones will allow the water to flow from the top to the bottom of the potato tower. This irrigation trick will keep the soil moist inside the potato tower; the potatoes will thank you for that one. Some use a pipe with holes.}}
{{Info|Banana leaves (or newspaper) are thin enough for the potato to understand the shortest way to catch the sun and let the stems pierce through. The banana leaves are also sturdy enough to hold the soil inside the tower; for newspaper, you might want a thinner mesh than the one we propose here.}}
{{Info|Feel free to plant other crops on top of your potato tower! Think about how long those crops will need to grow; if it takes the same amount of the time as the potatoes, go for it!
We planted beans on the side and on top of the potato tower to have a better yield.}}
