quad lisianthus establish close together — 6 to 8 in apart — so these upright plants will look better and support one another . Using wireloop stakesor singlestakesand ties is a honorable idea for variety taller than 18 inches . Place green stakes in former summer — they ’re almost invisible in the garden .

Cover the container with a plastic dome or aplastic wrapsecured with a synthetic rubber circle to bind in the moisture .
Place fluorescent orgrow lights½ to 1 in above the container ’s top . The seeds should receive 16 hours of light per twenty-four hour period until the seedling start to emerge , in about 2 week . During this clock time keep the temperature unvarying — 70 to 75 degrees . Once the seedlings start to emerge , remove the dome or credit card and adjust the lights so they ’re 1½ to 2 inch above the top of the plants . Nighttime temperature can be coolheaded now — 60 to 65 degrees . But do n’t have them drop much below 60 degrees .
irrigate the growing medium from the bottom now and keep it moist to the touch , not saturated . furnish good ventilation . You may begin feeding with a calcium - found fertilizer ( 13 - 2 - 13 ) or world-wide - purpose plant food at half military strength once a week now . At the end of this microscope stage , roots and the first leave , or cotyledon , have recrudesce .
2. Transplant the seedlings
Transplant lisianthus seedlings into 4 - packs after 7 to 8 weeks , when they have developed 2 or 3 sets of true leave . At this stage , the lisianthus seedling are not as prone to rosetting , so it ’s not as critical to keep temperature below 75 degrees . As you move them , hold on a leaf and use a modest spoon to take up out as much of the mass medium with the roots as possible , as the source are very sensitive . embed the seedling so that the bottom foliage are just above the commixture .
3. Prepare seedlings for outside
Continue to bottom water the container , but increase the feeding to half - strength every tearing . Let the medium dry out a little between watering now .
4. Harden off lisianthus seedlings
When they are 3 to 4 inches high-pitched and have 3 to 4 lot of unfeigned leaves ( usually around the end of May or first of June ) , move lisianthus plants outside . aim them outside for step by step longer menses of time to inure them for a couple of hebdomad first .
5. Move seedlings out to the garden
Once lisianthus seedling arehardened off , engraft them in moist , well - drained soil where they will get at least 6 hour of sunlight a mean solar day .
