You have lifted the amaryllis from the border: what matters for winter

Amaryllis cannot survive winter outdoors where you are, so the right step now is to let the bulb rest somewhere dry and frost-free. After lifting it, shake off the soil, let it dry for a few days at room temperature, then remove completely withered leaves and old roots that come away easily. Do not immediately cut off healthy green leaves if any remain, as they help the bulb build reserves; remove them once they yellow.

Store the bulb somewhere dark or dim, dry and cool; around 10–15°C works well. Do not water during dormancy. Check occasionally for softness or mould. In Västernorrland, Sweden, in October, the outdoor growing season is effectively over for amaryllis, so it should not return to the border until next summer if you want to grow it outside again.

To encourage flowering, bring the bulb out after its rest towards the end of winter, pot it with its upper part above the compost, and begin watering gently only when you see new growth. If it has mainly produced leaves before, it may need a proper rest followed by light and feeding during the next growing season to build enough strength to flower again.
