Title: Trident seeds
Post by: Dirk on August 01, 2012, 05:29 AM
Last fall I bought some Trident Maple seeds.
Planted them late fall and kept them outside for natural stratification.

The seedbed was exposed to temperatures as low as -20 degree Celsius. (-4 Fahrenheit).

Great result this spring: none sprouted.
I know that there are Maple species that that at least two years to germinate.
Is this so with Tridents?
Or is the exposure to deep frosts fatal?

In other words, can I get rid of the seedbed, or should I wait another year?

-BUMP-

Would love to hear someone with experience answer this question.

My understanding via Brent Walston is that trident maple seeds have to be fresh, making it very difficult to grow from seed.  I have tried several times and failed and now just order bare-root seedlings for my nursery...

I have found they rot easily kept outdoors unless drainage is perfect. I have good success stratifying them in my refrigerator where I can better control the moisture. In the spring when they start to swell or sprout in the fridge, I plant them outside.

Frank,

Do you collect your own or purchase?

You paid too much, probably for old seed, Schumacher cleans seed and ships, so not over dried.

Looks like a Putz tree in a Horst pot. Seed probably out of Denmark or something.

Get a germinating seed bed heater. If all else fails, use a reptile heater with some rock wool over it. Needs pretty good bottom heat for tridents to strike.

Once you get one tree, take cuttings. They are faster and larger faster.

I've never been able to get one to root...  I've got a forest I need to replace some trees in so any advice would be appreciated!

Cuttings are straightforward.

Dick - I'm in The Netherlands too - I'll give you a Trident if you want one...

Thanks Jerry,

I decided to try again, just started stratification with new seeds, purchased at Vreeken in Dordrecht.
I'm afraid the seeds are not very fresh: No one could tell me how old the seeds were.

If all fails again I'll be very happy to accept your offer!
b.t.w. I've seen your collection of trees on the internet! Very nice collection of trees Jerry!

Groeten
Dick

I second schumacher. I like them as a source for seed. I have never had awesome germination rates with tridents for whatever reason.  Japanese maples usually pop very easily for me.  The trident seeds rot easily in stratification and are just plain difficult.  I typically get a 40% germination rate. Soaked them in hot water for a few days, then kept them in moist paper towels in the fridge for 3 months, and finally sowed outside(mid-late march here).

So far I have only had a 25% sprout rate. Raining today, so hoping for some warm weather to follow for a few weeks. I can see some in the soil that are bent over and ready to pop, but the lower temps that moved in with the rain have stalled the sprouts.

Some of mine are all bendy cause I grow um under window screen to get some movement down low on the trunks.

Well Dirk about 4 years ago I planted Trident seeds in a tray and after several months nothing grew I emptied the tray into the garden. A month later I noticed a huge clump of trident trees growing in the garden!! By then I wanted to move the trees out of the garden and into containers. I did this operation in the summer against my best judgement! A horrible heat wave took place and I lost them all. It just goes to show never give up!

I'm anxious to try again.
Have to wait another month though before I can sow the seeds. Wether here
was good, for four days in a row. Next week we'll have snow again and temperatures
well below freezing.
It will be April before i get my seeds out of the fridge.

Trident and Japanese Maple seeds are in seedtray. JM seed already sprouted in the fridge.
Some JM seeds already above the ground. For Tridents its probably still to cold. Need to get heating underneath the seedtray.

Voilá

Came up with 16 JM and 16 TM seedling.
All separately in 4'' pots now.

I think not a very bad result: Had 16 TM out of about 50 seeds. That is over 30% if I calculate that correctly. JM even better.
Now we'll see what stays alive through next months and next winter.
