Antwort auf: Cypripedium 'Gisela' in pots? von Paul Perakos am 11 September, 2000 um 19:54:49:
Although it is possible to cultivate "Gisela" in pots it is not as easy as growing them in the garden. It is better to use big pots as the conditions are then more stable. The pot should be 8 inches (20 cm) deep, but the diameter could be 1 foot (30 cm) or more. You may plant a few 'Gisela' in one pot together with small ferns or Hostas to have a nice display. Use a crumbly soil, keep it slightly moist and fertilize regularly as with other perennials. Mulching with pine needles or something similar prevents the surface from drying out.
During winter the pot can freeze solid ('Gisela' survives at least -4°F / -20°C without problems) but make sure that the sun cannot reach the pot during day time. Don't worry that the shoot buds poke through the surface in autumn. That's normal and they will stop growing when reaching the light.
I hope this helps.
Good luck and have fun with your Cyp hybrids
