GREENHOUSE: Grandifloras are usually sown from Nov. 20th. -Dec. 15th. for Mother's Day and Easter pot sales. For May- June bedding plant and container sales, sow between Jan. 15th. and Feb. 15th. Seed sown Mar. 1st. will produce flowering plants by July 1st. Multifloras are used as a bedding plant only.
CULTURE: We use pure Jiffy Mix in our seedling flats, rather than soil mixtures - for better germination. Fill the flat to within 1/4 in/6 mm from the top and firm (especially the corners), so you don't get erosion when watering. Soak the seed flat thoroughly before sowing, with luke warm water (70°F/21°C) and a good fungicide to prevent disease. Mark the rows 2 in./5 cm apart, and 1/8 in/3 mm deep, .5 in/13 mm wide with the edge of a label or a marking board. If you are sowing several different colors in the same flat it might be a good idea to place a piece of cardboard across the flat on both sides of the row that you are sowing to prevent -mixtures. Broadcast the seed as thinly as possible in each row. Press the seed firmly into the surface. We do not usually cover with soil as some colors are light responsive. If you believe in covering the seed use coarse vermiculite as it retains moisture and allows enough light for proper germination. To conserve moisture, cover seed flats with plastic, glass or paper. For ideal germination soil temp. must be 80°F/27°C, (air temp. of 86° F/30°C days and 65°F/18°C nights). The soil temp. must not drop below 70°F/21°C. Use bottom heat if possible: Seed will germinate according to color (pinks, blues and whites first - reds last) in 5 - 1 0 days. Do not use cold water as it lowers the soil temp. and weakens tender seedlings. Uncover your seed bed at the first signs of germination to prevent tall weak seedlings. Grow seedlings cool at 65°F/18°C. Transplant 4 to 5 weeks after seeding, 1 - 1.5 in/3 - 4 cm apart and at the same depth as they were when in the seed flat. Grow at 55 -60°F/13 - 18°C for stocky plants.
