How to Feed Potato Plants

Updated February 21, 2017

Potatoes are fun and painless to grow as a root crop in your personal garden. These vegetables are highly versatile, and can be harvested and eaten at almost any stage of their growth. Homeowners and gardeners across the world enjoy growing their own potatoes, and presenting the home-grown product to their guest. Although potatoes are a hardy plant, though, they do require some specific nutrition. When growing potatoes, it's a good idea to give them some added nutrition at the time of planting.

Amend your soil as needed. Potatoes grow well in average soil with a little peat moss or compost mixed in for drainage. They should be in plots that get plenty of sunlight.

Fertilise your soil before planting to nourish a potato crop. Use 5-10-10 or 10-20-20 fertiliser.

Mix fertiliser and compost into the top 10 or 12 inches of soil. Always follow manufacturer directions when using fertiliser.

Plant your potatoes. Each planted potato should have 2 to 3 "eyes." If potatoes have more eyes, cut them in half and plant each half of the seedling.

Space your potatoes correctly; plant them 2 to 3 feet apart and cover them with soil. Make sure the potato seedlings are always covered with soil.

Water potatoes generously once a week. Add liquid fertiliser to your water to continue feeding the potato plants.


Only buy certified seed potatoes for growing, to make sure you get disease-free potatoes.


Fresh manure or lime in the soil causes scabs on the crop.
