It is recommended to plant camellias preferably in fall to ease root development and allow for better blooming the following year. Planting camellia in the spring from plants purchased in pot is perfectly possible but they will require regular watering at the beginning. Camellias can do well in neutral soil but will always do best in acid soil. They like sun but must be protected from scorching. Mix one part soil mix and one part garden soil. Water abundantly, add mulch in winter to protect roots. They will need regular watering during the first 2 to 3 years, especially if temperatures are high, in order to permit root development in the ground. As for fertilizer, you can add heath plant fertilizer or camellia fertilizer in spring or fall. Also, remember that pine bark mulch applied all year round can retain moisture, keep the soil cool, and as it breaks down increases soil acidity for camellias.
