Castle Mixture

Rape/Kale Hybrid

catch crop

‘Redstart is a fine, even crop.  I have found it to be less stalky than other rape/kale hybrids so the lambs are eating better’

Fraser Campbell, Ancaster Estate, Crieff.


  • Rapid and vigorous growth – matures in 12-16 weeks

High energy grazing for cattle or sheep. Can be used for summer, autumn or winter grazing. Fast establishment (can be sown later than kale). Ideal for out wintering systems. Has regrowth potential when sown early.

Sowing dates
June to mid-July. Sowing date is dependant on when the client wishes to utilise the crop. If you put it in too early it can bolt.

Utilisation dates
September to January/February (in a mild winter it can last until March). Frosts can cause a lot of grief if prolonged.

10-12 weeks
