Tangerine / clementine tree woes, help needed for treatment

Hi All,

Am new the forum and to be honest quite new to gardening so please go easy on me...

I have moved to a new house which has a tangerine / clementine tree. The leaves look pretty unhealthy though it seems to be full of ripening fruit. There are kind if black spots on the leaves and some white blobs inside around the branches. I'm attaching a few photos to show how it looks.

Could anyone identify what the problem might be and maybe suggest what treatment I could use?

Thanks a lot for your replies.

Best regards,
Paul

It is possible that your tree has black spot.

Black spot is a fungal disease.

This is what I feel might be the best advice:

   

Bryant said It appears to be either scab or black spot (nearly identical fungal diseases) the best (for non-chemical treatment) thing to use is a good compost tea sprayed all over the tree and soil beneath and surrounding the trees, this will help break the cycle via a protective coating.
   As has been mentioned by James Freyr, you will want to gather up all infected leaves, take them away and burn them completely.
   Adding more mycorrhizae around the root systems will also help as will using sea water (mineralization of the soil) to water with once a month for a few months.
