19 Genius Vertical Potato Tower Garden Ideas
Potato towers let you grow a good crop in a small footprint by adding soil as the plants grow. These 19 genius vertical potato tower garden ideas cover containers, methods and care for homegrown potatoes in tight spaces.
Potato tower basics
| Item | Why it works |
|---|---|
| Seed potatoes | Certified, disease-free tubers |
| Best types | Early and mid-season varieties |
| Start | Plant 10 to 15 cm deep after the last hard frost |
| Hilling | Add soil or straw as stems reach 15 to 20 cm |
| Harvest | When the foliage dies back, or early for new potatoes |
Tower types
- Wire mesh cylinder lined with straw.
- Pallet tower with removable front boards.
- Stackable wooden box tower that grows upward.
- Food-grade plastic barrel with drainage holes.
- Fabric grow bags that roll up as you add soil.
- Milk crates stacked and lined.
- Large trash can with holes drilled in the base.
- Chicken wire and straw layers of compost and straw.
- Vertical raised bed box with a hinged side.
- Tall pot or tub on a sunny patio.
Methods
- Layer compost and straw for a light, easy-to-harvest mix.
- Plant at several levels in boxes with side openings.
- Chit seed potatoes on a windowsill before planting.
- Add soil gradually to keep tubers covered from light.
Care and harvest
- Water deeply and evenly to stop hollow or cracked tubers.
- Feed with a balanced fertiliser at planting.
- Pick a sunny spot with at least six hours of sun.
- Tip the tower out onto a tarp to harvest.
- Rotate the tower site each year to reduce disease.
Tip: Avoid old tyres for edible crops because they may leach chemicals, discard any potatoes that are green since they contain solanine, keep potato leaves and berries away from children and pets because they are toxic, and lift heavy towers with help.
