Instructions for growing cactus from seed.
Mix 3 parts of commercial potting compost with 1 part of grit (not sand) and 1 part of perlite.
Level down into pots or a seed tray.
Soak the compost with water.
Sprinkle the seeds evenly over the compost. Do not cover them with soil, they need light to germinate.
Cover with a propagator lid, sheet of glass or Cling-film.
Place in non-direct sunlight at 70-80 degrees F (21-26C)
Keep the compost moist, but NOT wet, by spraying with water when needed.
Seeds should germinate within 2 weeks.
Watch out for damping off fungus and spray with a suitable fungicide immediately.
Keep the seedlings in indirect sunlight for about 6 months, then slowly let them have more light and less humidity. They will have a lush green colour if the light levels are right. If the epidermis turns red it means they are getting too much light, so shade with an appropriate material. Muslin or thin white cloth works well for us.
Be in no hurry to re-pot them. Wait until they are fighting for room.
Just ordered seeds and hope to have a bunch of baby cacti.
ReplyDeletesounds good to me :)
ReplyDeleteI'm looking forward to receiving my babies :D
ReplyDeleteI heard it takes up to 3 years for them to bloom.
I wonder how are you guys doing in the UK. Do you have to keep them always indoor?
in the UK they like to be either indoors or in a greenhouse. the UK weather will kill them :(
