Influences of irrigation frequency and method of fertilization on the growth and flowering of chrysanthemum grown under restricted root volume were tested. To study the effect of water regime, chrysanthemum cuttings were grown in pots and plants were irrigated regularly at 1, 2, 4 or 8 week intervals during growth period. In another pot experiment, the effect of fertilization method was tested as either foliar spray method at rates of 1.5, 3.0 and 6.0 g l-1; or fertigation application (in irrigation water) at rates of 7.5, 15 and 22.5 g l-1. Both, irrigation and fertilization experiments, were conducted to observe the growth and flowering performances of chrysanthemum. The obtained results showed that plants that irrigated weekly and fertilized with 3.0 g l-1 as foliar spray produced the tallest plant values but flowering was inhibited. While plants irrigated at two week intervals and fertilized with 15.0 g l-1 as fertigation method showed better flowering and produced the highest number of flowers per plant. It is evident that the numbers of flowers were affected by both irrigation frequencies and application method of fertilization. Irrigation frequency and method of fertilization can improve the growth and flowering of chrysanthemums grown in pots with restricted volume of soil.
