Sweet potatoes are nutritious, versatile, and delicious — but not everyone has access to a traditional garden plot. The good news? You can still grow a sweet potato harvest at home using simple containers like plastic tubs. Whether you live in an apartment, have limited outdoor space, or just want an easy DIY project, this method makes growing sweet potatoes achievable for everyone.

The key to success is choosing the right container. Plastic tubs are inexpensive, lightweight, and easy to manage. They also allow you to control soil quality and watering more effectively than in‑ground planting. Start by selecting a tall tub with good drainage holes at the bottom. Fill it with a rich potting mix blended with compost to provide essential nutrients. Then plant your sweet potato slips — young shoots grown from a mature sweet potato. With proper care, these slips will develop into strong plants.
Sweet potatoes thrive in warm conditions, so place your tub in a location that receives plenty of sunlight. Water regularly, but avoid overwatering; the soil should be moist, not soggy. As the plants grow, occasional fertilizing will help roots develop into large, healthy tubers. Unlike some crops that require intensive maintenance, sweet potatoes in tubs stay relatively low‑effort once established.
If you’re wondering how to grow sweet potatoes in plastic tubs, the concept is surprisingly straightforward and rewarding. The tub acts like a mini garden bed, giving you the freedom to cultivate large, plentiful roots without needing a yard. Just make sure the container is deep enough — sweet potatoes need room to expand underground. Fifteen to twenty gallons is ideal for one plant, but smaller tub sizes can still provide a decent harvest if spacing is managed well.
Harvest time usually occurs about 3–4 months after planting. You’ll know the sweet potatoes are ready when the vines begin to yellow and die back. Carefully lift the entire tub and tip out the soil to reveal your freshly grown roots. With a bit of shaking and gentle brushing, you’ll uncover healthy, sweet tubers that are perfect for roasting, mashing, or baking.
Growing sweet potatoes in plastic tubs is an effective way to enjoy homegrown produce — even if you don’t have a traditional garden. It’s simple, affordable, and a fun way to bring fresh vegetables to your table. Give it a try this season and enjoy the satisfaction of harvesting your own sweet potatoes!
