And in addition to the black spots the stem and leaves on the top of the trunk appear to be bunched up and deformed. What is it and how do I get rid of them thanks.

From your description there could a number of reasons why your pawpaw tree is looking so poorly. If the nutrient level of the plant is poor then the plant is more susceptible to fungal disease and attack from insects. By making sure that your tree is well fertilised in spring and again in autumn with a fertiliser that is high in potassium, phosphorous and magnesium should ensure that it will become more resistant to fungal disease such as "black spot". Try Yates Thrive Natural Citrus & Fruit Pelletised Plant Food. It's enriched with Dynamic Lifter and has added nitrogen, phosphorus and potassium to give your fruiting plants the right balance of nutrients for their growing needs. Applications of seaweed extract throughout the year can also boost the health of the tree providing a natural source of minerals and growth stimulants to promote root growth and maintain the overall health of the tree.
