Growing Non-GMO Cambridge Blue Lobelia Flower Seeds

Lobelia seeds are small; although they are easy to germinate and grow, the hardest part is planting! Directly sow lobelia seeds outdoors when temperatures are consistently around 65 F. For early spring blooms, begin the seeds indoors 4-6 weeks earlier than their planting-out date and germinate under a grow light. A heating pad can be useful for keeping the soil temperature at about 60 F. Lobelia seeds are frequently sown 3 or 4 to one spot; the bunch is transplanted together and treated as one plant. This is one way to bulk up your crop earlier than having single plants.

When transplanting seedlings indoors to outdoors, it is crucial to slowly acclimatize them to their new environment. Place them outside for a few hours a day and gradually increase the duration until they are ready to transplant; this process is referred to as 'hardening off.' Lobelia prefers evenly moist conditions. Water regularly. If the plants appear leggy or the flowers look sparse, lightly shear the tops of the plants by no more than one-third. Immediately follow with fertilization; this can encourage a new flush of blooms.

Lobelia flowers perform at their peak with regular fertilizations or compost applications. If using traditional fertilizer, apply a time-release granular at the time of planting or transplanting and then supplement throughout the season every 4-6 weeks with a low-strength liquid feed. For compost, incorporate well-rotted compost into the soil at the time of planting or transplanting, and then every 6-8 weeks, apply a fresh handful or two at the base of each plant. In particularly fertile or well-maintained soils, this maintenance step may not be necessary to keep up the blooms.
