In mid-spring when all danger of frost is over, you can move your potted amaryllis plants outside to a partly shaded area. After a few weeks, you can remove them from their pots and plant them in your flower garden or in groups in front of your shrub beds. Amaryllis need a sunny spot -- full morning sun and if possible filtered in afternoon. Loosen and prepare the soil in the chosen area; remove the bulb from the container and carefully set it so that the top one third is above the soil line. This is totally different from most other bulbs which are buried completely and it’s important. Mulch and water and give dilute fertilizer a few times over the summer if your soil is nutrient poor, too much nitrogen can decrease flowering. These glorious plants are relatively pest free.
