Cactus question
"Nick Williamson" wrote in message
om... Hello all, I'm growing some cactus from seed. They popped up in early November and are currently in a seed tray, in John Innes seed compost with a layer of Vermiculite on top. The biggest one is probably not much over half an inch high. I don't know when to repot them, or what to repot them into - would they be ready for cactus compost yet? All advice welcome... TIA Nick I wouldnt do anything with them until next spring. Water very sparingly. -- Tumbleweed Remove my socks before replying (but no email reply necessary to newsgroups) |

You can get away with leaving repotting them until after they start to crowd each other. A nice guide to seed raising at: http://www.teessidecacti.org/BCSS/CULTIVAT/seedcult.htm Cacti seedlings will tolerate being kept in a propagator and never quite dried out for the first year or so. They don't like being saturated but they grow best at first if kept supplied with some water. At this time of year they will need as much daylight as you can give them or they will go leggy and weak. I usually prick out cacti seedlings after a year, and then pot them up individually after 2 or 3 years. Fast growing ones can be done sooner. Cacti seeds are best planted early spring to get a full growing season in strong sunlight before they have to face the inexorable grey sunless days of winter. I usually grow my cacti seedlings in JI #2 cut 1:3 with coarse grit sand for faster drainage. Normal seedling compost is a bit rich for them. Potting on into 1:2 JI/grit mix later.

I'd second all of this. They'd cope with cactus compost, but the start of winter is a bad time to repot a plant which really doesn't like cold and wet - repot in about May or June when they're growing strongly. They're not yet ready to cope with drought, but they don't want much water. -- Kay Easton Edward's earthworm page: http://www.scarboro.demon.co.uk/garden/ |
