Anyone grow katsura from seed?

The growth on these things is incredible (even in my hot kansas sun). Sowed seed 3/1, now is almost 3 feet tall at 31". What would be a expected height at the end of season 1?

Wow - that's impressive!

I think you exceeded the expected first seasons hight already

I have grown a few Cercidiphyllum japonica, 'Magnificum'.
They grow fast when young and slow down at around 30 ft.
I sold 600 of them twenty five years ago to a wholesaler for $4.00 a piece. I had so many I was lucky to get rid of them at any price. They were 6 ft. tall their second year.

Mike,
Did you prune off the suckers? I think it looks nice but not sure if it's taking up a lot of the water supply for the main trunk.

I have grown a bunch (no where near what Mike's grown, though). Mine have never grown that much (height plus all the side shoots) during their first year. I do prune off the lower branches to encourage a more "tree form" early (mostly for immediate aesthetics). I would be very impressed by that much growth this early.

Yes, I prune off the suckers. I made raised beds and then broadcast the stratified seed in the early spring on the beds and then raked them in. The Katsuras came up like lawn seed!
I thinned a grove of them and the stumps sprouted like mad even though I cut them off as short as possible. The trunks make fine firewood. I'll get some pictures when it gets light outside. It's almost 4am now.

Wet out there this morning. We got a normal month's amount of rain in one day Tuesday
This grove is about the size of a city lot. I originally planted them out to sell on about 4 ft centers. An employee hacked them in half at about 6 ft. and completely ruined them. I left them alone and they grew a lot larger. They were planted too close to a row of Thuja plicata and as they got larger, started to lean. Then an ice storm leaned them over more. I finally got in there with a chainsaw and thinned them. Every stump sprouted new growth. I made the problem worse!
So I cut all those sprouts off and when they sprouted, I hit em' with a broad leaf weed killer. This is what's left. All the trees are Katsuras.
