Hi,

I just purchased a house that has a fully grown Macadamia tree in the backyard. Its got abundant of nuts. The previous owner had the water sprinklers set to 1/2 hour twice a week that waters the tree and its surroundings. However, I recently changed the setting to 7 mins 4x a week. Now, I noticed that some of the young Macadamia nuts are turning brown. Also, I noticed that the sprinkler is directly spaying on the trunk hence the bark started peeling. I love the tree and would need advice on proper maintenance and care. Attached are the pictures. Thanks!
