As some of you know I usually grow quite a bit of stuff from seed each year, around 10-15 flats of jiffy pellets which translates into a shit load of seedlings. This year I decided not to do as much and concentrate my efforts more on the stuff I already have. With that being said I am still planning to doing around 6 flats which translates into 432 seedlings if they all come up, but we all know that never happens. I can say for the most part over the years I have been pretty lucky with stratification and germination on most seeds. But trident maple has not been one of them. Each of the last two years I have collected hundreds of seed and ended up with just a few seedlings. I think 3 the year before last and about 7 last year. Now I think I have a tip to offer!
Usually there is a “from seed” thread each year, but I couldn’t find one this year. I did find y’all doing this from seed contest, so I figured I would share this here.
I stratify my seed in paper towels and plastic bag as many of you do. I keep the fridge I use at about 40 degrees. Here’s a mini tip I learned from
@0soyoung, I spray my paper towel with 3% hydrogen peroxide and water mixture. I check my seed about every three weeks during stratification, and spray and redo my paper towel and plastic bag on any seeds that are moldy. I have three bags this year.

In the past with other species, I have left them in the fridge past the determined stratification period until they have germinated. That way you get about 100% success rate on the seed you plant.
Now is where the tip comes in. The seeds above were done with their 90 day stratification a couple of weeks ago and as usual (at least for me) none of them had sprouted. So this year I decided to do something different. Two weeks ago I started setting them out of the fridge during the day from about 8am to 3pm every day. I didn’t inspect them or even crack the plastic until yesterday where I found about 10 had germinated and I planted those. I put the rest back in the fridge and continued the same routine.

My wife starts a lot of her flowers from seed under grow lights like I do my seedlings. Today we discussed how she was going to have more room this year because I was not doing as much as I usually do. I showed her how I had done the trident seed and open a package and found about 12 more that had sprouted over night! I will continue this process daily and see how it turns out. She may not have as much room as I thought.

Now some of you may already know about this technique and just say “duh!” but I didn’t, so I thought I would share.
