How to grow

Cultivation Freesias are naturally winter-growers starting into growth in autumn through to late spring so need to be grown in a frost-free greenhouse. Plant in pots of John Innes No.2 loam-based compost with added grit sand. Place in full light with good ventilation, water well and feed monthly until flower buds form. After flowering dry off pots and store dry over the summer. Corms can also be stored dry over the winter and planted in well-drained soil in spring for later flowering. Lift in autumn and store dry

Propagation Sow seed in containers at 13-18�C in autumn or winter. Remove offsets in autumn
