Kennebec Potatoes Growing Tips


Kennebec Potatoes are typically planted in the spring, about 2-3 weeks before the last frost. Plant seed potatoes that are about 2-3 inches in size and have at least one “eye” or sprout.

Plant them in well-drained soil that has been amended with compost or other organic matter.

Pot Requirement

Typically, these potatoes are planted in the ground, but they can also be grown in pots or containers if you don’t have access to a garden.

To give your Kennebec potatoes enough room to grow, use a pot that is at least 18-22 inches in diameter and 16-18 inches deep.


The soil should be loose, well-draining soil with a pH of 5.0-5.5. The soil should have plenty of organic matter, such as compost, manure, or peat moss.


Potatoes need regular watering in order to thrive. For best results, water them with 1-2 inches of water per week, deeply and evenly, but avoid saturating the soil or standing water around the plants.

Make sure to water the soil, not the foliage, as wet foliage can encourage disease. Additionally, water your potatoes in the morning, as this will give the leaves time to dry off before nightfall. Also, it will be a good idea to let the topsoil dry a little bit before you water the plants again.


For maximum yields, use a fertilizer that is specifically labeled for potatoes. Make sure to follow the directions on the package carefully.

Alternatively, you can also go for a balanced liquid feed. Feed it once after planting the potatoes, then apply a second application of fertilizer after the plants have started to flower. This will help ensure the potatoes are well-nourished and have enough nutrients to produce a good harvest.

Also, water the bed thoroughly after applying the fertilizer to help it get into the soil.

Harvesting Kennebec Potatoes

Kennebec potatoes are typically ready to harvest about 90-100 days after planting. The plants will begin to die back, and the foliage will turn yellow when the potatoes are ready.

Carefully dig up the potatoes with a fork or shovel and let them dry in the sun for a few hours before storing them.
