Yellowing of Camellia leaves


Yellowing leaves on camellias can have many different causes and good gardening practice suited to this particular type of acid loving plants could help.

Should the problem persist then further investigation into the possibility of a disease should be investigated. A sample taken to your nearest nursery is then recommended.


  1. Most likely your camellia is hungry. As an acid-loving plant, camellias don’t tolerate alkaline or limey soil, as they cannot extract enough nutrients from it. In spring use an acidic fertiliser, such as Plus Rose, Azalea & Camellia Fertiliser, to make the soil or growing media more acidic, and a few handfuls of Black Marvel Garden Compost, to top up organics. And at Christmas time give them another feed.
    If you live in an area with very alkaline soils, it’s going to be difficult to lower the pH enough to keep your camellias happy. In such situations it is best to keep camellias in pots, with an acidic potting mix designed specifically for plants that require soils of pH 6 or less to thrive.
  2. With regards to watering, not enough water during the summer months can lead to problems such as weak buds and compromised flower quality. Regular deep watering is very important to keep your camellias happy. It is also a good idea to keep roots cool and moist over summer. If they are in the ground, adding mulch will definitely help.
  3. On the other hand, camellias don’t like wet feet. Make sure soils are well-drained, as waterlogging can lead to root decay. Waterlogging is especially common in container grown plants where the potting media loses structure over time. Timely repotting avoids this.
  4. Camellias also like a sheltered morning sun position, away from hot, drying winds.
