Keep in mind when planting that Mexican is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside.
Growing Mexican from seed
Try to aim for a seed spacing of at least 3.12 inches (8.0 cm) and sow at a depth of around 0.39 inches (1.0 cm).
Transplanting Mexican
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Mexican is a tender plant.
