The nectarines on my tree are not round and smooth; they are lumpy. Is there something I need to do for the tree?



The lumps on your nectarines are probably the result of earlier insect damage--probably a sucking insect like stink bugs or lygus bugs.  Corryneum blight can cause small bumps, more like freckles or little moles, but my guess is insects.  You can spray your tree in the spring with a dormant oil before the blossoms open.  That will cut down on the number of insects, but not cut them out entirely.  We have a booklet called "The Home Orchard Pest Management Guide" that you can buy, which gives lots of good guidelines for when and what to spray.  You can also get on an email list that will notify you of when and what to spray.  To be on that list, send an email to marion.murray@usu.edu and ask to be put on the tree fruit advisory list.  She also has one called "Landscape Advisory" and one called "Small Fruits & Vegetables"  You can be put on all 3 if you choose.
