FAQs
When is the best time to plant Stuttgarter Giant sets?
These sets are best planted between August and November to take advantage of their winter-hardy nature.
Can I grow these in containers?
Yes, they grow perfectly in containers provided the pots have drainage holes and high-quality, free-draining compost.
How do I know when the onions are ready to harvest?
The onions are ready when the foliage turns yellow, withers, and begins to fall over naturally.
How should I store the onions after harvesting?
After curing them in the sun, store them in a cool, dry, and well-ventilated location, such as a mesh bag or a slatted crate.
Do I need to fertilize these onions?
While they do not require heavy feeding, a light application of general-purpose vegetable fertilizer in early spring can boost growth if the soil is poor.
How deep should I plant the sets?
Plant them deep enough so that the tip of the bulb is just barely visible above the soil line.
Troubleshooting
Onion sets failing to sprout
Ensure they were planted at the correct depth with the pointy end facing upwards and that the soil is not overly saturated or frozen.
Bulbs appearing mushy or rotting
This is often caused by poor drainage. Improve soil aeration by adding grit or ensure your container has adequate drainage holes.
Poor growth or stunted bulbs
Check for weed competition. Onions are sensitive to weeds, so ensure the bed is cleared regularly to maximize nutrient uptake.

Setup, Compatibility & Care
Upon receiving your 250g pack, keep the sets in a cool, dark, and well-ventilated area until planting. To plant, push each set into the soil so that the tip is just visible at the surface. During the growing season, keep the area weed-free, as onions have shallow roots and compete poorly for nutrients. Water sparingly, only during extended dry spells, as excessive moisture can impede bulb development. When harvesting, gently lift the bulbs with a garden fork and allow them to dry on the soil surface for a few days before moving them to a cool, dark place for long-term storage.
