How do you save if it is turning brown? Is there a blend of fertilizer to use?

Many evergreens periodically lose some of their older foliage at the center of the plant or from the base of the plant, so what you are seeing may be normal. Or it could indicate an insect problem. Spider mites can cause the symptoms you describe. Spider mites like living in dry, dusty places. You can hose off the interiors of your plants to discourage spider mites and to remove the dead foliage. Before you do, though, check carefully for webbing in and around the stems and foliage. If you find webbing, spidermites are the culprits. Periodically hose the plants down to discourage spider mites from taking up residence. If you don't see signs of spider mites it could be saturated soil conditions that are causing your tree to decline, your tree needs to be in well drained soil. Best wishes with your plants!
