How to Force a Crab Apple

Greetings, I'm going to try and bring a small cascade crabapple in to force early blooms. My club is having a display and I'd like it to be available.

What is the time frame for doing this. I would like it to be in top form for March 29th. Is there any guest on a good date to bring it in from the cold to my 62F temp house for this?

Thanks
Jay

I think it's going to be very hard to give you any kind of definitive answer. Does it bloom reliably every year? When? Can you see vestigial flower buds on the branches now?

Jim, it is very reliable in blooming. It has had flowers for the last 4-5 years. It will have fewer flowers in some years and more in others. I wish I had watched it more, but I can not say how soon after budding out did it flower.

It has been suggested that 3 weeks is the time frame.

If the suggester is from Smuggler's Notch, VT, go with it, Otherwise, use your instincts.

Thanks Jim.... I guess unless I hear otherwise I'll give the three weeks a try.
Either way I'll keep you posted here on the progress.

Dont mind if i chip in, I trained in plant production now run my own garden center and landscape garden business. This has given me a insight in to forcing so to speak. Some of the info i will say is a bit late but fun to try for next time. 1) in the autumn (sep-oct) feed with sulphate of potash to set bud. 2) going on your time frame, glasshouse grow at 10 - 15oc with extended light time so you have a good 7-8h natural light. 3) feed with K again no nitrogen as you want flower not leaf. 4) if budding too quick then reduce light and temp to hold till show.

Greetings, I said I would update the thread so here goes. I moved the tree into my 40 degree F sun room for a week then into my house, which is kept at 59-65F this time of year. The tree opened blooms in 2 1/2 weeks from coming into the house (3 1/2 from coming into the sun room). I tired to upload a couple of pictures but I guess I failed.
Thanks all for the help

That's great news Jay. Sounds like you timed it just about right. How did the showing go?

Thanks Ed... I finally figured out the picture thing...I hope.

The Matsuri was extremely enjoyable. A very nice day for the entire family. Many many things for kids.
A couple of pictures of our booth follow.
