Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to grow horseradish [title] Obtain horseradish crowns or roots to plant. [step] Purchase a cutting of horseradish from a greenhouse or grocery store. Most of the time, these places will sell crowns (the uppermost part of the plant) or roots that are pre-cut and ready to plant.

Ending1: The crown will not grow roots in late autumn. [substeps] Horseradish crowns will need 7 to 10 days to germinate and 18 to 20 days to mature into roots in late fall. Ending2: The crowns, however, often have only a very tiny number of roots growing out of them. It's better to plant them slowly, without much effort, to avoid any root rot. Ending3: Most gardeners start horseradish from crowns, as the plant grows from the roots and only its weed-like flowers produce seeds. [substeps] Like carrots or potatoes, horseradish roots are ready to go straight into the ground. Ending4: [title] Dig up the soil around the roots. [step] Use a pair of hands to help guide the rooting process.
