When should I plant my pansies outside in the spring?

Answer 1

Ideally, these will be planted out in Autumn, and not Spring. This article will help: https://www.gardeningknowhow.com/ornamental/flowers/pansy/pansy-planting-time-outdoors.htm

Answer 2

First you must harden off your plants for roughly a week unless they were outdoors where you purchased them. Pansies can be planted in early spring once the ground is workable - not icy and not super wet. Depending on recent weather, that may be now for PA. Pansies tolerate frost and even a freeze (under 25 F for 4 hrs.)
