Camellias need to be irrigated regularly using the right quality of water. Avoid irrigating Camellias with hard water. Ideal water should be less than 13 degrees Clark . The water from the houses' mains is normally classified as 0-10 deg Clark - soft; 11-20 deg Clark medium and 21-38 deg Clark hard. The post will discuss about tips for growing camellias.
One thing you can do is contact the local authorities and find out how hard the water is before you use it to irrigate your Camellias. There is also special equipment that can be used to test the water hardness at home. Water harder the 13 degrees Clark needs to be softened using softening agents which solidify the lime contained in the water or filter it out. Do not boil mains water as this will prove lethal for the Camellia.
