Propagule Collection:	I harvest bulltongue during late August through early October (when fully mature and before any significant shattering occurs) by manually shattering fruit clusters on the plants and collecting falling seeds in a container.
Propagule Processing:	Seeds require only hand-sieving through screens (1/16 [1.157 mm] round hole) to remove small amounts of trash. Seeds can be stored dry in zip-lock-type plastic bags for at least 6 mo. I have also found that post-harvest storage in a moist medium (I used wet paper towels and sphagnum peat moss for experimental purposes, however, other media would probably be acceptable) at 5.5 øC (42 øF) or in cold water (5.5 øC [42 øF]; changed monthly to reduce algal growth), are 2 useful ways of maintaining seed viability. The cool temperatures and moist conditions serve as a stratification process.
Growing Area Preparation/ Annual Practices for Perennial Crops:	I use a 3:1 (v:v) sphagnum peat moss:sand growing medium amended with commercially recommended quantities of pelletized slow-release fertilizer (for example, 1.8 to 3.6 kg/m3 [3 to 6 lb/yd3] Osmocote 13N:13P2O5:13K2O; 8 to 9 mo release rate at 21 øC [70 øF] or 1.8 to 3.6 kg/m3 [3 to 6 lb/yd3] Sierra 17N:6P2O5:12K2O; 3 to 4 mo release rate at 21 øC [70 øF]; The Scotts Company, Marysville, Ohio), 4.7 to 5.9 kg/m3 (8 to 10 lb/yd3) dolomitic lime, 0.89 kg/m3 (1.5 lb/yd3) Micromax micronutrient fertilizer (The Scotts Company, Marysville, Ohio) and a wetting agent (I use 0.59 kg/m3 [1 lb/yd3] 2000 G AquaGro [Aquatrols, Cherry Hill, New Jersey], which is no longer marketed). I pasteurize the sand in an electric soil sterilizer for 30 min at 82 øC (180 øF) to reduce weed problems.
Establishment Phase:	Plants germinate best on saturated medium (28% to 53% 10 to 11 wk after planting) after moist and water storage, although I have observed good (49%) germination of bulltongue after 5 mo of dry storage. I keep the medium saturated on a commercial ebb and flow greenhouse bench (Midwest Trading, Denmark) with water maintained 0.6 to 1.2 cm (0.25 to 0.5 in) deep. Greenhouse temperatures range from 13 to 38 øC (55 to 100 øF).
Active Growth Phase:	Continued seedling growth of Sagittariaspecies also seems to be best on saturated medium indicating a preference for anoxic conditions.
