Line the bottom of the tower with a layer of straw, which will provide aeration and help with drainage. Next, add about a foot of nutrient-rich soil on top of the straw. Choose high-quality soil or enrich it with compost to ensure the potatoes receive the necessary nutrients.
4-Planting seed potatoes
Place the seed potatoes, which are small, whole potatoes or pieces with at least two eyes each, about three to four inches away from the inner edge of the tower. Plant them approximately six inches apart from one another. This spacing allows the potato plants enough room to grow without crowding each other.
5-Fill it to the top
As the potato plants grow, continue to layer the tower with straw and soil as needed, always making sure to leave enough space for the plants to develop. Add more layers as the stems grow taller, and the potatoes will form along the buried stems.
6-Water properly
Consistent watering is essential for a successful potato tower. Keep the soil consistently moist but avoid overwatering, as excessive water can lead to rot. Applying a layer of mulch on top can help retain moisture and suppress weed growth, reducing the need for frequent watering.
