Calceolaria INTEGRIFOLIA

Sowing and germination

Calceolaria seeds are very small, almost dusty, and ripen in dry capsules. It is not advisable to soak such seeds, so the substrate itself is disinfected: before sowing, it is spilled with a weak solution of potassium permanganate and dried. Scarification and stratification are not required. Seeds are sown superficially, without embedding - they need light for germination. The crops are moistened from a spray bottle with a solution of a growth stimulator: SUPERthrive, HB-101, Aminozol, Epin or Zircon, covered with a film or placed in a greenhouse and germinated in the light at a temperature of 18-20°C. Under favorable conditions, the first shoots appear within 2 weeks, the main germination is completed in 15-20 days, and individual seeds may linger longer. Crops need regular ventilation; waterlogging and drying out are unacceptable.
