Lewisia cotyledon SPECIAL Mix

Lewisia, Bitterroot

Culture guide

Uses:
Evergreen perennials for rock garden, pot plants

Exposure:
Partial shade

Garden height:
6″ / 15 cm

Crop time:
8-10 months

Sow time:
January-March for green pots; June-August for flowering in pots the following year

Sowing method:
2-3 seeds per plug

Germination:
Yields best germination results if exposed to a period of cool temperatures before temperatures are raised to 60-65 °F (15-18 °C). Germinates in 3-6 weeks. Cover seed lightly with vermiculite after sowing.

Growing On:
Transplant plugs after 6 weeks. Grow on at 54-65 °F (12-18 °C) in a well-drained, lime-free growing medium. Vernalization is required for flower initiation.

Media:
Use a well-drained, growing perennial substrate with 0-15 % clay, 0-20 % parts (e.g. bark, sand, perlite),1-1,5 kg/m³ complete balanced fertilizer, 0-2 kg/m³ slow release fertilizer (3-9 months), iron-chelate, micronutrients, pH: 5.0-6.0.

Temperature:
Grow at 12-18 °C or outdoors. In winter indoors frost free at 3-5 °C or outdoors. Outdoor fleece cover needed. In spring the plants start to grow for 4-8 weeks at 15-18 °C. Cold temperatures at 7-14 °C will increase the cultivation time. A chilling period (vernalization) is required for flower initiation

Fertilization:
Low-moderate fertilization levels are required. Fertilize the crop weekly with 100-150 ppm nitrogen (at 2 kg/m³ slow release fertilizer in substrate), using a complete balanced fertilizer. Avoid high ammonium and high nitrogen levels. Don’t fertilize after mid September. In spring fertilize 100-150 ppm nitrogen of a complete balanced fertilizer. Prevent magnesium deficiency by applying magnesium sulphate (0,05 %) 1-2 times and in case of iron deficiency (above pH 6.0) apply iron-chelate for 1-2 times.
