Some new shoots on the end of branches, seem to get all brown & crusty and die. Is this a disease or an insect?

Since moving to a new house, this nectarine tree was not in a good way. We tidied it up and have been feeding & watering it. It has since tripled in size, but alot of the new shoots with young soft leaves at the very tips are very brown/dark reddy-brown and crusty. They are dying for some reason. It's only on the new shoots.

Answer: Dear Lee,

Without seeing the damage, it is difficult to determine exactly what the problem is. It could be that the new growth is being attacked by aphids. Aphids are sucking insects that suck the sap from the new growth causing the leaves to become twisted and distorted. Both nymphs and adults can be found on trees throughout the year. Nature’s Way Citrus & Ornamental Spray

Green Peach Aphid will return to stone fruit trees in autumn to lay their eggs. Once the stone fruit trees have lost their leaves, mid- winter is then time to spray the tree with Lime Sulphur. to eliminate any pests that tend to overwinter.

Inspect your tree for this pest and if you are still unsure, take a sample of foliage to your local nursery for identification.
