Perhaps one of the most popular crops grown this way is potatoes and, fortunately, for gardeners asking how to grow potatoes in a bag, this approach is a foolproof way to harvest a bounty of potatoes this summer. The mounding process remains the same, but the trick is to roll down the sides of the grow bag and roll up as you add compost through the season. Following this tried and tested technique, even in a grow bag, will produce delicious potatoes for your summer suppers.
Finally, in addition to fruit and vegetables, Jen recommends 'using bags for growing dahlias, which ensures that each plant can grow in an isolated environment so that if tubers are affected by gall, it doesn’t contaminate the rest of the bunch.' If you are thinking about when to plant dahlias in a grow bag, the process is much the same as the usual approach, and planting in the springtime will produce brilliant blooms in the summer months ahead.

Top tips for using grow bags
- Select grow bags that are the right size for your plants - for shallow-rooted crops, such as onions or lettuce, smaller grow bags that are approximately 5 gallons are suitable. However, for deep-rooted plants like carrots and parsnips, a taller grow bag is ideal. For those looking to grow potatoes, a larger grow bag is recommended so that the mounding-up process is effective. Grow bags that are approximately 10 gallons in size are recommended.
- Use a good quality potting mix - always fill grow bags with a high-quality, well-draining potting mix. Drainage in the soil is important, but the permeable liner will cause the grow bag to drain relatively quickly. Combining a small amount of coco-coir, such as this from Walmart, with your potting mix can help with moisture retention, reducing watering duties in the summer months.
- Positioning - place your grow bags in an area with adequate sunlight in a sheltered spot in your backyard. Most crops require a good amount of sunlight hours to help them grow. Tomatoes, for example, need plenty of sunlight for a good crop of fruits. Use grow bags with handles, as this will help you to move and rotate crops if necessary.
- Staking and support - certain crops that grow tall or possess a vining habit may require staking or training along a trellis. Install supports at the time of planting, using canes, for example, or if you are looking for more of a project, why not try and build hazel plant supports? As your plant grows, use garden twine to tie in. This preventative strategy will ensure that strong winds do not damage your crops.
Reusing grow bags
The ability to reuse grow bags is one reason they are so economical and are considered a sustainable growing method. At the end of the growing season, in late summer or fall, remove your plants and dispose of them on the compost heap.
Spent compost is useful and one practical flower bed idea is to redistribute this soil in your borders, helping to improve the quality and nutrition of your soil. Take the time to clean and dry your grow bags, storing them indoors for the winter. Helpfully, many grow bags will flatten, meaning they are easy to store.
While grow bags will not last as long as traditional terracotta flowerpots, annual cleaning, drying and storing will help to extend the lifespan of your grow bags, so it is worth taking the time and effort to follow this process.
