I have some baby trichocereus cactuses that were mailed to me and many are half sticking out of the soil, and will need to be re-potted anyway. I also have some root stimulant powder: Indole-3-Butyric acid, 0.4% --- should I use it on them? These cactuses are a very moisture-tolerant, fast growing species. I see on the label of the root powder it doesnt mention cacti, just 'cuttings'.
since they already have roots, you don't need to use the hormone. seedling cacti should be kept in indirect light for the first year and sometimes for two years. do you know how old they are?
Months old, no more. But they're the type that flourish under direct sun. Even right under the sky we get so much overcast here in southern BC I'm tempted to leave them under the open skies anyway --- you think not? Thanks for the response. PS: By southern BC I mean the south-western part of BC, not the 'pocket desert, east of the mountains.
I'd be cautious with them for the first bit. If these are the ones I think they are, in the wild the adult cactus, yes, loves full sun, but babies are generally shaded by other plants until they're about 15 cm tall.
standard procedure with cacti seedlings is indirect light for at least the first year - regardless of whether they like full sun as an older plant or not. they're very delicate at this stage and are very susceptible to burning. also, when young they tend to like more moisture than when they're older, so water more frequently than you would for a larger specimen...once they get to the point where they can be in full sun, you can back off on the watering.
Really? Ok, thanks for that --- I was planning ways to give them the full-meal deal on direct sunlight. Regards, Tom
Yeah, they sure are cute --- they really do grow on you, don't they? I seperated these ones --- each column is a different plant, the result of too many seeds being sown too close together.
