Solanum tuberosum
Toxic to cats and dogs — keep it out of reach (source: ASPCA (Solanum — green parts, sprouts & green tubers toxic)).
A sunny south-facing window with 6+ hours, or a grow light.
Keep evenly moist — water when the top inch of soil is dry.
Forgiving and beginner-friendly.
Potatoes grow surprisingly well in a deep bucket or grow-bag and are one of the more satisfying container roots. The foliage, sprouts, and any green tubers contain solanine and are toxic, so only the cured, unblemished tubers are eaten.
About Potato (Container)
Potatoes (Solanum tuberosum) come originally from the Andes of South America and grow surprisingly well in a deep bucket or grow-bag, which makes them one of the more satisfying container roots for a renter. You need a deep container of around 20 litres and a bright spot, plus the habit of "earthing up", adding soil as the stems grow. One sprouted seed potato can return a few pounds of new potatoes in good light.
The plant is easy to grow and you can even start it from a sprouting kitchen potato. Give it bright light and steady, medium water, and keep developing tubers covered with soil. The foliage, sprouts, and any green tubers contain solanine and are toxic, so only cured, unblemished tubers are eaten. Harvest new potatoes after flowering, or wait for the tops to die back for mature ones, usually around 70 to 100 days from planting.
What it’s like to grow
Potatoes are easy and rewarding, with the main risks being light and chemistry rather than fuss. Tubers that catch the light near the surface turn green and solanine-rich, which is why you keep mounding soil over them. Low yields trace back to shallow pots or weak light. Keep the container deep and bright and water at the medium level. The foliage, sprouts, and green tubers are toxic to cats and dogs, so it's one for a grower who can earth up reliably and keep pets away from the leaves and any greened tubers.
What to expect
First harvest in about 70–100 days. It’s forgiving, so it’s a good one to learn on. No sunny window? It also does fine under a clip-on grow light.

Plant a sprouted (“chitted”) seed potato or a sprouting kitchen potato eye; each grows a new plant and a fresh crop of tubers.

Tips
- Start from a sprouted seed potato in a deep container and “earth up” (add soil) as stems grow.
- Keep developing tubers covered with soil — light exposure turns them green and toxic.
- Harvest “new” potatoes after flowering, or wait for the tops to die back for mature ones.
Common problems
- Green, solanine-rich tubers from light reaching them near the surface.
- Low yields in shallow pots or insufficient light.
