Plant problems - leaf discolouration ? nitrogen deficiency? I was help to name this plants as Dodonaea viscose. It was photographed in May 2006 in North Cyprus. Is leaf discolouration due to nitrogen deficiency? Krystyna
Could be a variety of things. Maybe Agriculture Ministry can help. Here we have USDA Cooperative Extension, with regional offices.
Could be iron chlorosis where the veins stay green but the rest of the leaf yellows. http://www.ext.colostate.edu/PTLK/2115.html Other types of chlorosis. http://plantclinic.cornell.edu/FactSheets/microchlorosis/microchlorosis.htm http://www.urbanext.uiuc.edu/focus/chlorosis.html Newt
It looks like chlorosis to me but I could be wrong. I had a fruit tree that looked almost identical to your specimen with the green veins and yellowing leaves. I remedied this with some Iron chelate and blood meal. -Eric
