Technical Information<br />

Uses: Landscape/bedding plants, mixed containers and<br />

large containers<br />

Garden height: 16-20’’ (40-50 cm)<br />

Available as: Raw seed<br />

Sowing method: 2-3 seeds per plug<br />

Germination:<br />

Stage I and II: 14-21 days at 68-72 °F (20-22 °C)<br />

Stage III and IV: 21 days 64-68 °F (18-20 °C)<br />

Requires light for germination.<br />

Temperature: Grow at 61-64 °F (16-18 °C)<br />

Media: Use a well-drained, growing media with 1-1,5 kg/m³<br />

complete balanced fertilizer, pH 5.5-6.0<br />

Sowing media: Media with very low soluble salt levels and<br />

pH 5.5-6.0; keep soil slightly moist but not wet.<br />

Plug Culture: From Stage II gradually lower humidity levels and<br />

maintain uniform soil moisture levels. Do not let soluble salt level<br />

rise above 0,75 EC. Start fertilization at 50-75 ppm nitrogen in a<br />

well balanced formula. During Stage III and Stage IV fertilization<br />

levels can be increased up to 100-150 ppm.<br />

Growing on: 5-6 weeks after sowing, transplant 1 plant into a<br />

pot 4-4,5’’ (10,5-12 cm).<br />

Fertilization: Moderate – high fertilization levels are required.<br />

Fertilize the crop weekly with 200 -250 ppm nitrogen, using a<br />

complete balanced fertilizer. Avoid high ammonium and high<br />

nitrogen levels. Avoid pH above 6.0, as high pH causes iron<br />

deficiency. Apply chelated iron, if chlorosis becomes a problem.<br />

To prevent magnesium deficiency apply magnesium sulphate<br />

(0,025 %) 1-2 times.<br />

Crop Time: Plug crop: 4-6 weeks; flowering pots: 10-12 weeks<br />

Cultural Hints: Avoid high salt levels in media especially in the<br />

early plug stages. Salvia farinacea are susceptible to leaf scorch<br />

if soluble salts rise or pH drops.<br />
