With over 1,500 genera and 23,000 species, daisies are one of the largest families of flowering plants. With broad dark leaves and flower stems that range from 15 to 24 inches tall, daisies blossom in a range of yellows, reds, oranges, pinks and white. Regarding the perennial variety of daisies, the University of Florida Extension notes that their crowns eventually sink into the garden soil, which can cause the crown to rot. To prevent crown rot, lift the daisy and move it to a new planting site every two years.
Prepare the new planting site several weeks before transplanting. Till the soil to a depth of 1 foot and remove rocks, weeds and other garden debris. Incorporate 1 to 2 inches of peat moss, compost or other organic matter into the soil.
Water the soil around the daisy thoroughly to facilitate lifting the plant and to guard against transplant shock.
Dig a new hole for the daisy that is 1 foot deep and 1 foot wide. The hole might have to be enlarged once the daisy is lifted to accommodate a root ball that is larger than the hole. Place the soil from the hole into a bucket or on a tarp.
Loosen the soil around the daisy by inserting a shovel about 1 foot away from the plant on all sides. Reinsert the shovel and lift the entire root ball of the daisy, being careful not to disturb the root system.
Move the daisy to the new planting site. Place the root ball in the hole and adjust the depth of the hole; once planted, the crown of the daisy should be at or slightly above the soil level.
Add the soil from the bucket or tarp around the root ball, filling the hole half full. Water thoroughly to settle the soil. Finish filling the hole, stopping at the plant's crown. Tamp the soil down gently and water again.
