Healthy Camellia tree has several leaves burnt(see picture)
I'm really struggling to know what is going wrong with these sasanqua fragrant camellias in my garden.
These trees are 7 - 8 years old and have lush green healthy looking leaves.
All of a sudden the 3 Camellia trees are showing portion of the leaves that are burnt(see picture).
I water them 3 times a week for 10 minutes (using sprinklers connected to ground level). They get around 4 - 5 hours of early morning to 1 PM sun.
I fertilize all my plants with miracle grow (acidic) fertilizer at the rate of 1 TB spoon miexd with 1 Ga water per plant, once a month.(The recommended doze is every 7 - 14 days).
All other plants (even smaller ones) are doing well with the miracle grow fertilizer(all are acid loving plants). So, I'm not sure what is going wrong...
Sorry, I could not find a way to upload a picture here.
