When to sow: Feb – March
Spacing: 30 x 30cm
Celery tips: If you can start the seeds with heat in February, that’d be ideal, otherwise unheated in March will be fine. Seeds can be sown into large modules or small pots and planted out at final spacing in May. Harden off and cover with fleece to protect from cold after planting.
Celery is evolved from a marsh plant and is very thirsty, so be sure to water it in dry weather.
