The last average frost date for south coastal British Columbia is March 28. March is the month gardeners in this region must use to get ready to take full advantage of the growing season ahead. Gardeners in other regions can refer to our Regional Planting Charts for more specific advice on timing.
Below is a list of seeds to start in March. Seeds started in March will be ready for transplanting into the garden by the time the nighttime temperatures have warmed up in May. Other seeds actually benefit from cool weather and the risk of frost, and they are shown below for direct sowing in March.
