How Deep Should You Plant Calla Lilies?


Calla lilies are bright, flowering plants that produce blooms in a range of colors, including red, pink, peach and yellow. They are hardy plants that are grown from bulbs; planting calla lily bulbs appropriately helps them thrive.

  • Planting Depth

According to the University of Illinois, you should plant calla lilies about 1 inch deep in the soil. Plant each calla lily bulb between 1 and 2 feet apart from each other. You may also choose to start calla lilies inside in early spring and then transplant them to your garden. If so, position the rooted bulbs so that their green tops are above the soil line.

  • Planting Conditions

Choose an area of your garden that receives full sun or partial shade and a moist, rich soil. Calla lilies are highly tolerant of water, and so are suitable for planting along the edge of a pond.

  • Warning

All parts of the calla lily are poisonous, and it should be planted with caution in areas where children and animals reside. The calla lily produces oxalic acid, which causes inflammation, nausea, vomiting and diarrhea when ingested.
