Towering Spuds

Growing potatoes vertically

TOWERING SPUDS - or Growing Potatoes Vertically

This method is great for gardens short on space, as long as there is access to Pot_tower_0_MGG.jpgsunshine, a few hours a day. You get a decent crop growing the potatoes vertically, rather than in-ground. The idea is that you are creating more surface area, in a small space, for the potato plants to get the sun’s energy.  The leafy stems will poke through the sides of the mesh.

You will need some support for the tower. I use rigid plastic mesh, about 90cm wide, rolled into a cylindrical shape and then kept upright with wooden stakes. You could also use chicken wire mesh, or whatever is handy to keep the potatoes and soil contained, vertically.

Place some newspaper over the ground where you want the tower to stand. Erect the tower using the mesh and the stakes, leaving one side open so you can access the inside to add the tower contents. Line the inside of the tower with loose straw and place some also on the newspaper. Add soil or compost to a 30cm depth. Then put your potatoes around the edge, about 20cm apart, with the potato eyes or sprouts facing outwards. Water well.

Cover with about 30cm of more soil or compost. Place more potatoes on the soil as before, around the edge, eyes facing outwards. Repeat this layering for another 1 or 2 layers, depending on how many potatoes you have, or how much soil/compost you have available. Water well at each layer.

At the top, create a shallow depression so that when you water, the water is directedpot_tower_3_mgg.jpg inwards to help feed the developing roots. Top with more straw as a mulch. You could put another potato to grow at the top in the middle, or alternatively, grow other shallow rooted vegetables at the top of your tower. The potatoes will sprout and the leafy parts will grow outside of the tower, leaving the tubers to develop in the tower.pot_tower_4_mgg.jpgpot_tower_5_mgg.jpgpot_tower_6_mgg.jpg
