| I have planted both the orange and lemons and fanfare gaillardia. They both started with wilting leaves which turn yellow, stems wilt and then the whole plant dies. When I apply a pesticide it get worse and I can't save them. Any ideas what I have done? Both were doing very well for a while. The fanfare even bloomed and had several buds. I use 7 garden dust and neem oil alternating once every 2-3 weeks.

|You may be killing your plants with such loving attention! Gaillardia grows best in a spot with full sun; it likes hot, dry weather and tolerates a wide variety of soils. Gaillardia does best where it's hot and dry but not where it's hot and humid. I'd stop using the neem and Sevin (unless you see insects; then identify them and use the least toxic control such as insecticidal soap). Water them deeply once each week and trim off the spent flowers which will encourage additional flowers. Hope this information helps!
