Description
- New and rare pink onion variety
- Arrives in breathable bags for healthy sets
- Grow in containers or beds to suit your space
- Heat treated for 20 weeks to minimise bolting
Rosanna gives you the prettiest of slice onion from bulbs growing on robust and reliable plants. Rosanna scores high marks both in the kitchen for salads and an essential ingredient to gamey casseroles and does well for performance outdoors during the growing process.
The unusual variety gives you full and generous-sizes bulbs from late summer. Simply harvest your plants as the green leaves start to yellow and wilt whether this is from a raised planter such as a Veg Trug or directly from an allotment bed.
How to plant:
Prepare the soil by raking the area after sprinkling some pre-planting Onion, Garlic and Shallot Feed over the area. Create a shallow trench and place your sets (pre-planted bulbs) 10-12cm (4- 4 1/2in) apart. Fill the trench so that the tips of the sets are poking above the soil. Keep well-watered in dry spells.
Useful tip:
At harvest time let the intensity of your onions mellow a little by leaving them outside on the plot resting on straw or similar. Then collect them, plait them up and hang them in a dry, cool shed to use as and when you require.

How to Guide
Planting Onions and Shallots
Prepare the ground with our Pre-Planting Onion, Garlic & Shallot Fertiliser to ensure strong bulb development and growth, early ripening and maturity, good skin and bulb firmness.
Planting Sets:
Place onion and shallot sets in the soil with their pointed ends facing upwards. This ensures proper growth orientation.
Leave 5 to 10cm (2 to 4 inches) of space between individual onions and 15 to 20cm (6 to 8 inches) between shallots.
Create rows of onions with 25cm to 30cm (10 inches to 1 foot) of spacing between them. For shallots, allow 30 to 45cm (1 foot to 18 inches) between rows.
Planting Onion Plants:
Utilise a dibber to create holes in the soil that are the same depth as the plants' original root depth in their cell tray.
Place the plants into the holes, ensuring they sit at the same depth they were in their cell tray.
Gently water the area to facilitate proper settling of the plants into the soil.
