LOBELIA Annual Dwarf
GREENHOUSE: Lobelia is rather slow to flower. Sow Jan. 25th. to Mar. 15th. for May pak sales at @ 80°F/ 27°C soil temp. for 20 days. Seeds are very fine, just try and get them as thinned out as possible - 1/16 oz/ 2 gr sows 8 (12 x 12 in/ 31 x 31 cm) flats at 1,000 seedlings per flat. Do not cover seed, press them lightly into the soil surface. Seeds germinate in about 5 - 10 days. Grow at 45 - 50°F/7 - 10°C then transplant in small clumps of 4 - 5 seedlings per group, about 3 or 4 weeks from seeding. If seedlings get a bit tall before transplanting - due to a thick stand, trim them back. They do not like soil high in acidity (too much peat moss). Shade blooms just before May sales - for richer colors. NOTE: For July blooms seed must be sown no later than Mar. 25th., indoors. Transplant outside in June, 8 in/20 cm apart - in partial shade. Lobelia requires lots of water during dry periods. Use trailing type in hanging baskets and brighter dwarf varieties to brighten dark corners.
