Hi I'm semi retired field crop agronomist in west central Saskatchewan, so I am attempting to learn about horticulture. The building has some cultivated areas along the walls were past residents propagated some marigolds and cherry tomatoes. I saw them coming up as volunteers and started watering them. With the marigolds should I prune them back to the ground now since we have had a hard frost or wait until spring
