You will know if it fails to leaf out normally next spring. Leaf yellowing and drop could be caused by a nutrient deficiency like a lack of nitrogen or iron. Lower, older leaves on a nectarine tree will turn yellow first if nitrogen is insufficient. An iron deficiency, especially common in alkaline soils, may be indicated by leaf tissue that turns yellow while veins remain green. Mar 01, These diseases are most active following a wet season and occur when buds are open. Wet buds can develop this blossom blight in 6 to 7 hours when temperatures are 45 F.
(7 C.) or lower. Treat with a fungicide or insecticide.
Learn the proper time for treating a sick nectarine tree. Jun 16, Bacterial Spot Bacterial spot, another disease that can affect nectarine trees, causes"reddish-purple spots with white centers" on the leaves that fall out, leaving a holey appearance, according to the Georgia Cooperative Extension.

This canker can develop collar rots at ground level, developing firm, jelly-like, oozing lesions (Figure 10).
In the Georgia Cooperative Extension Diagnostic Guide to Common Home Orchard Diseases, researchers explain that the disease can also affect the twigs of trees, causing dark red lesions.
Sep 21, Leaf fall is usually a sign that the tree is entering its annual dormant stage when the energy used for wood growth is redirected towards the production of fruit-bearing buds. The University of Florida recommends pruning peach and nectarine trees between December and February, before the first bud breaks. Correct dormant pruning is particularly important during the first few years of growth to select branches that will help the tree. All of the usual signs of a root disorder will be present, which include: reduced growth, sparse foliage, and stunted, yellow leaves.
More specifically: there may be an increased amount of sap around the root collar, black root-like strands in the soil, and fan-shaped fungal mats ranging from dark to light color (typically white to off-white) will form between the wood and bark of infected trunk and root tissues.
