Planting young plants
From Early Spring TO Early Spring
Keep in mind when planting that Bidens 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. Bidens likes a position of full sun and remember to apply water fairly sparingly. It prefers moist and rich soil. Ensure that temperatures are mild and all chance of frost has passed before planting out, as Bidens is a tender plant.
