The grafted gardenia response to spray iron and gave the treatment of spraying every 30 days the highest rate of increase of the height plant to 68.04 cm and the highest rate the number of flowers per plant reached 7.30 flower and fewer buds falling reached 2.13 bud flower. Non-grafted gardenia similar trend response to iron foliar, treatment iron foliar every 30 day gave highest height plant 50.50 cm and the highest weight and diameter and age flower was 3.21 g and 3.20 cm and 4.11 day
