Growing Lavender from Seed in South Florida: Light and Variety Issues

South Florida gardener: 'Lavender Lady' and 'True Lavender' seedlings indoors (75°F, 3 hrs direct sun through tinted window). 'Lady' wilts at 2 inches; 'True' barely sprouting.

Insufficient Light

3 hours through tinted glass is far too little. Lavender needs 10+ hours intense light (e.g., 40W fluorescent shop lights).

Damping Off Risk

Wilting at 2 inches suggests damping off fungus. Remove plastic cover if used.

Tinted Glass Problem

Filters out essential light spectra.

Better Approach for South Florida

Grow Spanish (L. stoechas) or French (L. dentata) lavender—heat/humidity tolerant.
Start seeds under lights, then move outdoors to protected spot, then full sun after 10 days.
Window sill with tinted glass will not work.

English lavenders need winter dormancy; Spanish/French thrive in Zone 10.
