The Camellia Japonica is more commonly known as the Japanese Camellia. There are many varieties with flowers of white, pink and red and range in height from 6 to 10 feet. The leaves on the plant are very dark green, thick and shiny which creates a striking background for the beautiful winter blooms. The Camellia Japonica is recommended for gardening zones 7 through 9 but will grow in zone 10 with the proper amount of shade and water.
Prepare the container for your Camellia Japonica plant by first placing 2 inches of stone or gravel at the bottom. Camellia Joponica plants have shallow roots, but need a wide container. Normally wide containers are also deep. The stones will help give it weight at the bottom and help with drainage. Place the container in a partially sunny location. Plant in spring or early fall.
Fill to within 7 inches of the top with regular garden soil. The roots will not go this deep and there is no need to amend this part of the soil.
Mix one part potting soil with one part compost and fill to within 2 inches of the top of the container. Do not fill to the top or the soil will spill out during watering.
Work in some aluminum sulfate to bring the pH down to a range of 4.6 to 6.5. Follow manufacturers' directions on how much to use per amount of soil in the container. The normal pH of most potting soils is 7.5 and Camellia Japonica thrive in an acidic soil.
Place your plant in the center of the container by digging out a hole a little larger than the root ball. Gently spread roots and place in the hole. Cover half the roots with soil and water to compact the soil. Continue to cover to the level it was planted in the container you purchased it in. Press the soil down firmly around the trunk.
Water the plant well and then top with a layer of mulch. Water twice a week and increase watering during hot, dry spells throughout the summer.
