Sticky black sap

Eileen107

hi, one of my small patio fruit trees (bought last year) has this very dark sticky sap where the top branch grows from the main stem. Can anyone advise whether this is normal & should I be doing anything about it. Grateful for any info.

Thankyou AnniD, I’ve also put it on the fruit & veg section & have had a couple of very good answers 👍
