Two fertilization experiments were conducted with first-year seedlings of baldcypress [Taxodium distichum (L.) Rich.] in containers (substrate = composted pine bark). First, seedlings were subjected to factorial combinations of dolomitic lime, soluble fertilizer (SF), and incorporated controlled-release fertilizer (CRF) (19.0N–2.6P–8.8K; 8- to 9-month release). Lime decreased growth. Incorporated CRF [4.8 kg/m3 (8 lbs/yd3)] yielded more growth than a single weekly application of SF (N = 0.5
