Camellia is a genus of flowering shrub consisting of about 200 species. Camellias are evergreen and some species can grow up to 25 feet in height, though they more commonly reach about 12 feet. Camellia flowers are produced in spring and summer, and can be any of a number of colors, depending on variety. Camellias are native to eastern Asia, but can be successfully grown in most temperate climates around the world.
Plant camellias in spring after the final frost of winter in a location with fertile, well-drained soil. Ensure the planting site receives bright morning sun with partial afternoon shade when daytime temperatures peak.
Dig holes twice as wide as the root balls and of equal depth. Remove young camellia plants from their containers and place the root ball directly into the prepared planting holes. Refill the holes with soil and water thoroughly to compact the soil.
Spread a 2-inch layer of mulch over the soil surrounding the camellia flowers. Start the band of mulch about 3 inches away from the stem to allow room for growth. Refresh the mulch whenever it begins to deteriorate.
Water camellia flowers twice per week for the first month of growth, and then reduce the frequency of watering to once per week during spring, summer and fall. Apply water to camellia flowers once every two weeks during winter, when the plant is dormant.
Feed camellia flowers once per month during spring, summer and fall using a balanced 10-10-10 NPK fertilizer. Water the soil both before and after applying the fertilizer to prevent nitrogen burn. Follow the instructions on the label for proper application.
