Yellow Easter flowers or lilies are common in homes and gardens across the United States. These plants survive indoors and outside temperatures close to 70 or 80 degrees F and spruce up a spot with their color and beauty. Although these lilies survive outside winter temperatures if proper measures are taken for their care and warmth, they are usually brought indoors where temperatures are slightly warmer. Transplant Yellow Easter flowers from their nursery containers or pots to the outside ground in early spring after the danger of last frost has passed.
Prepare the new planting site prior to digging up your Yellow Easter flower plant so it spends minimum time outside the soil. Select a spot that receives 6 hours of sunlight every day and has well-drained soil. Add sulfur or lime to lower or raise the pH of the site so it is neutral 6.0 or 7.0.
Dig a 6- to 8-inch-deep hole that is a foot wide over the planting site with a trowel. Add 2 to 3 cups or handfuls of organic compost or peat moss into the hole to enrich the quality of soil.
Insert a blunt knife around the outer edges of the nursery pot or container to loosen the soil. Encircle the outer perimeter several times. Tilt the pot to a side and gently shake it to extract the Easter lily plant along with attached bulbs. Gently shake it to remove loose soil.
Lower the bulb to the same depth it was in the pot. Add more soil into the hole if it is too deep, or remove soil if it is shallow. Position the roots in the middle of the hole and spread them out around the bulb to provide them plenty of room to spread and grow. Backfill the hole with soil to cover the transplant, and tamp it down to remove air pockets between the bulb and roots.
Water the area immediately with a watering can so the soil is evenly moist. Apply a 2-inch layer of mulch around the soil to help retain moisture in the soil, thus keeping the roots cool.
Feed the Easter lily plant bone meal or bulb fertilizer in the fall. Also add a few more layers of mulch to protect it from harsh winter weather. Remove the mulch in early spring or when the weather starts turning warm, and enjoy the blooms when the plant starts flowering, which is usually the end of spring of this year or the next.
