Graden Planting Depth
You may have bought your calla lilies as dormant rhizomes, which look like bulbs. Plant calla lily rhizomes 4 to 6 inches deep in a prepared garden bed in spring. Larger rhizomes should be planted deep enough so the top of the rhizome is 2 inches below the soil's surface.
Subsequently, one may also ask, how deep do you plant calla lilies?
Calla lilies are typically planted in the spring. However, wait until the threat of frost has passed and the soil has warmed sufficiently before planting calla lilies. Calla lilies should be planted rather deep, about 4 inches (10 cm.) for greater results, and spaced approximately a foot apart.
Also Know, when should I plant my calla lily bulbs?
WHEN TO PLANT: Calla lilies should be planted in the spring after all danger of frost has passed. For a head start, you can plant the rhizomes in pots indoors about a month before planting them into the garden. FLOWERBEDS AND BORDERS: Calla lilies grow between 1 and 2 feet tall, depending on the variety.
Many people treat their gift calla lilies as annuals. They receive a potted flower, or buy them for spring decorating, and then toss it when the blooms are done. In truth, though, calla lilies are perennials and you can actually save your potted plant and watch it bloom again next year.
