Stuttgarter Giant Yellow Onion Sets - 250g

These sets are best planted between August and November to take advantage of their winter-hardy nature.

Yes, they grow perfectly in containers provided the pots have drainage holes and high-quality, free-draining compost.

The onions are ready when the foliage turns yellow, withers, and begins to fall over naturally.

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.

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.

Plant them deep enough so that the tip of the bulb is just barely visible above the soil line.

Ensure they were planted at the correct depth with the pointy end facing upwards and that the soil is not overly saturated or frozen.

This is often caused by poor drainage. Improve soil aeration by adding grit or ensure your container has adequate drainage holes.

Check for weed competition. Onions are sensitive to weeds, so ensure the bed is cleared regularly to maximize nutrient uptake.
