SOW
When to Sow Turnip Snowball in the UK
Sow from March to August in short rows every few weeks.
Use that window as a practical starting point rather than a fixed deadline. In colder or exposed areas, delay outdoor sowing and planting; in mild sheltered areas, the earlier end of the range may work. Tender crops should remain protected until frost risk has passed.
Sowing Indoors
Sow Turnip Snowball in modules where protection is useful, keeping seedlings bright and evenly moist.
Sowing Outdoors
Sow or plant Turnip Snowball into prepared soil once conditions suit the crop, then thin before plants compete.
PLANT
Spacing and Planting Out
Follow the packet spacing and leave enough room for airflow and access at harvest.
Before planting outside, harden off indoor-raised plants over 7–10 days unless the crop is fully hardy and already accustomed to outdoor conditions. Water the planting hole or container first and avoid leaving young roots exposed to sun or wind.
SMALL SPACES
Growing Turnip Snowball in Pots and Containers
Use a container at least 25–30cm deep with drainage holes, allowing one mature plant enough width to develop. Match compost moisture to the crop and avoid crowding.
Container checklist
- Use drainage holes and raise pots slightly so surplus water can escape.
- Fill with fresh peat-free compost suited to edible crops.
- Leave a watering lip below the rim and check pots more often in sun or wind.
- Use a strong support at planting time if the mature crop will climb or become top-heavy.
CARE
Watering and Feeding
Water deeply rather than little and often, then adjust feeding to the crop and the fertility of the compost.
Variety note: Harvest around golf-ball size for the best texture; the young green tops are edible too.
WATCH FOR
Common Problems
Slow growth
Check light, temperature, moisture and root room before adding more feed.
Pest damage
Inspect regularly and protect young plants early with suitable mesh or physical barriers.
Poor harvest
Crowding and interrupted watering are common causes in small containers.
PICK
Harvesting Turnip Snowball
Pull white roots young from late spring into autumn.
Use the harvest timing in the packet notes as your main guide; weather, sowing date and container size can move the harvest by several weeks. Harvest in the coolest part of the day where practical and handle produce gently. Regular picking encourages continued cropping in fruiting and cut-and-come-again plants.
GROW TOGETHER
Companion Plants
Choose neighbours with similar light and watering needs, and keep enough space for both crops to mature.
