The effect of concentration of nutrient solution on the growth of Calluna vulgaris ‘Allegretto’ cultivated outside on ebb-and-flow benches was investigated. The standard nutrient solution contained 200 N, 21 P, 83 K and 12 Mg (mg dm-3) and microelements. EC of the standard nutrient solution was 1.7 mS cm-1. Half strength (EC 1.1 mS cm-1) and double strength (EC 2.7 mS cm-1) nutrient solutions were used in the experiment. The best growth of heathers was noted when nutrient solutions with 1.1 and 1.7 mS cm-1 were used. Increased concentration of nutrient solution for fertigation of heathers resulted in increased accumulation of salt in the growth medium, especially in its upper layer. Calluna vulgaris ‘Allegretto’ fertigated with a more concentrated nutrient solution had increased N and reduced Ca and Mg content in the leaves.
