i have mine in shallow tray to but burried slightly, i water around them rather than on them and sit them on sunny window ledge, i have quite a few leaves coming now,i would put in greenhouse i think if water dropping on tops, now mine have leaves im going to put into pots

This is the first time I have tried the 'sitting on compost' technique and I'm pleased to say I have quite a lot of growth showing at present. I have them in individual pots inside a trough which I occasionally put approx. an 1/8" of water in so they can absorb moisture from the bottom.
I am so looking forward to their flowering as I just love the continuous flowering with so little attention and (touch wood) trouble from pests or disease all the way through until frost at the end of the season....

Thanks Sanbaz / Bogoniafan. I've a long way to go before I get any leaves but don't intend putting them into flowerbeds until beginning of June so hopefully if they can get gowing they will grow quickly. Will move into greenhouse and push into compost a little further. We need some sunshine in Scotland to help. :o)

not to bad here TCG, not raining and a bit of sun on and off, have you still got snow there, poor you

Unfortunately yes Sanbaz - we sit in a valley, so it often skips us, but the Moffat hills are covered in snow. Last week was a horendous week - a right mixture - frost, gailforce winds with heavy rain & sleet & snow - very, very cold. Think cold spell's to last well into next week as well but I'm taking the opportunity this weekend to plant up as many seeds & pot on wintered plants as much as possible regardless - might as well make use of the extra holiday days off work. :o)

sounds like you have had it rough TCG, so glad we havent had sleet or snow here, so sunny today so it may help my pond hole dry out a little, thats another story lol, hoping its going to be sunny tomoz to so we can start putting surrounding pond right,i hate it when things go wrong hahah, of well we live and learn :o))

All begonias now moved into greenhouse Sanbaz - can you tell me how much you watered round them when they were corms - did you keep the compost only slightly damp or do they like their bottoms to be quite wettish. Will they eventually produce roots? They're holding their own (apart from the ones I lost in the polytunnel that had started to look a bit suspect for mold) which I removed - guess was no much condensation in there for them. There are only a few more shoots over the last week since moving to greenhouse but I'm not too sure if I need to water then more, or water them less? Can you help please?

just kept them slightly damp to touch and found that was enough TCG, and yes will produce roots, mine doing ok in growhouse now to, just keep them watered a bit more as they grow ;o)
