Indoor & direct sowing
Radish: Sowing and germination
Indoor pre-culture usually only for early greenhouse varieties.
Successive sowing possible; sow winter radishes from July onwards.
Planting & site
Radish: Planting and spacing
Only for pre-grown seedlings for early harvests.
Site & practical notes
Pro tip: Sow radishes in the same row as carrots. The fast-growing radish acts as a row marker and loosens the soil for the slower carrots.

Practical tips
Radish Practical tips
Common beginner mistakes
Sowing too densely without thinning later results in puny roots.
Success pattern
Regular watering and the use of fleece in spring almost always guarantee a good harvest.
High-impact tips
Apply crop protection netting immediately after sowing.
Grower observations
Especially in midsummer, radishes tend to bolt extremely quickly; shadier spots are worth their weight in gold then.
