potatoes #867963

Asked May 11, 2024, 6:43 AM EDT

I have a question about potatoes growing in containers. I planted the correct amount of seedlings (1 per 5 gallon in a 20 or 25 gallon container, I have both). They are growing like mad. But now the containers are full to the brim after hilling, and there is already 18" of new growth on top. Should I let the potatoes grow and stop hilling? Or should I try to enlarge the sides of the pots and keep hilling? T hanks.

Potatoes are so fun this time of year...  the higher you mound the soil the more potoates will be made.   I would not recommend trying to extend the container though.   Let the potatoes complete their life cycle and maybe plant again for the fall season.

Thank you! Can I continue to  cover the leaves and just leave 6” visible?

Yes... the more of the "stem area" that you continue to cover the more potato tubers that can grow.
