Forcing Hippeastrum out of their natural season is common practice for some, though I grow mine allowing them to follow their own schedule. Most bulbs are forced for the Christmas holidays, or thereabouts.

As long as your bulbs have previously received the best care possible, and have been allowed to recharge before the forced dormancy, they should perform beautifully.

Please post photos when your bulbs open their blooms!

Thank you for the reply jodik,
I realize these bulbs flower easily in most climates where cold is typical of winter?

The reason I wanted to know this process, was because even though it is well known by the commercial bulb producers, I did not know the process and was unable to get this information off the web.

Also for those people on the forum, in tropical areas? Who also do not know this process? They now may want to try flower these bulbs as well, as currently these bulbs may grow in the tropics though do not flower for them?.

I can now flower bulbs at other times of the year so that I can try to set up crosses with other species like the yellow flowering Zephyranthes sp aff. flavissima Ravenna etc., to see if it is possible to produce a yellow hippeastrum??

The original image above has a slight error, in the dates? which the bulbs were put into fridge, the correct date was 9th February 2009 not 24.03.2009 (24th March 2009) which was when the bulbs were taken out of the fridge, The white label on pot has the correct dates.

I enjoy hybridizing all types of plants and often find information like this is well know (to commercial growers etc?), though often not available on the web, so I publish it on forums like this one, so that it can become common knowledge.

Here is a link that might be useful: Zephyranthes sp aff. flavissima Ravenna

I apologize jodik , for not answering your question in previous post.

Yes, little short of me being hit by a bus????? or the bulbs being eaten by animals?

Will post an image of these hippeastrum bulbs in flower if not in this thread will include the original image along with an image of bulbs in flower in the finial post.
