Growing Guide & Production Protocols
Cultivation & Growing Guidelines
Lobelia erinus– often called ‘trailing lobelia’- adds a soft, cascading veil of vivid color to baskets, window boxes, and early‑spring displays. This cool‑season annual thrives in morning sun or bright partial shade, consistently moist, and well‑drained soil. With fine foliage and masses of small fan‑shaped blooms, lobelia provides an airy texture that complements larger flowering plants and fills mixed containers with graceful spill‑over.
Stick cuttings quickly, maintain 70°F (21°C) early, then cool to 65°F (18°C). pH 5.8–6.2, EC 0.5–0.8. Feed 50 ppm N, increase gradually. Use fungicide at sticking and week 2; pinch for better branching.
Danziger’s breeding brings modern garden strength to this classic crop, enhancing heat endurance and maintaining flower coverage well into warmer months.
