Shrub turn yellow, how to deal with it?
Is it a yew? Yews are evergreen and get fall red berries. Yews hate to have their feet wet. Is a down spout or your sump pump pouring water onto that side of the yew? Divert the water source away from the roots of a yew. I doubt that it would be a fertilizer deficiency since its just one side of the plant. Fertilizer deficiencies affect the color of the entire plant, not just one branch. Disease signs like a yellow branch can show in just one area, multiple areas, or the entire plant depending upon the stage of progression. A disease usually starts in one small part of the plant and spreads to the entire plant over time. You can tell if its a disease if you monitor the plant and see that its spreading over time. Sometimes you can see fungal fruiting bodies develop. These will be dark/light spots, bumps etc. on the needles.
Reply:Coperas - an iron fertilizer. Or poke rusty nails (metal) around the drip line.
Reply:I think that your shrub could have a disease because my evergreen plant has started to go yellow, and someone said it has probably got a disease (for plants only) I don't know what the disease is called though, but you could look it up.
Reply:An acidic fertilizer may help, there are several to choose from for evergreen's. Also make sure the soil has good drainage around the shrub.
