Poorly Rowan Tree

Question

My Rowan which we planted two years ago has very droopy dark green leaves which are curled into themselves can you advise me what is wrong and how to help care for it Thank you

Answer 1

Check the leaves for pests such as aphids or scale, which suck the sap from leaves. Borers also can be a problem. Rowan trees are susceptible to several diseases including fireblight. Rowans also prefer acidic soil (less than 6.0 pH), so a soil sample may be needed. These articles should help:
