Germination - the Science of Seeds!


The other night, I settled down with a cold beer to watch Tottenham take on the San Jose Earthquakes in a pre-season friendly. Now, once I'd had a good laugh at their pitiful stadium, and sneered a few times at the inane American commentators trying to pretend they understood football, I started to get a bit bored. It wasn't what you'd call a good match; truth told, it was just a runabout to get a bit of fitness into their legs.

After ten minutes, my eye drifted to the green folder on the dining table that is home to my gardening notes. I started flicking through the 2010 planting plans, and before you knew it I was grading each crop. I awarded them a massive 100 points if I'd had germination figures of over 80 per cent, a less massive 75 points if the figures had been between 60 and 80 per cent, a middling 50 points if the germination had been between 40 and 60 per cent, a mere 25 points if it had been between 20 and 40 per cent, and a big fat zero if germination had been under 20 per cent.

Once everything had been given a score, I set about calculating the average for each seed supplier. As a point of interest, when I first started this gardening lark, I read many blogs and forums where the order of the day was to only purchase seeds from small companies with heritage or rare breeds, and the person selling them had to have dirty hands, a scruffy dog and a name like Tarquil. To buy seeds from the big names was, apparently, frowned upon.

Knowing less than an idiot meant I was inevitably drawn to one or two large commercial garden centres. My seed collection soon consisted of many packets from the big names. I had seeds from Mr Fothergills (I suspect he's not a real person, as his picture on the packet is a cartoon), Suttons, Unwins and Thompson and Morgan. Now, I don't think I actually excluded any of the big boys in my initial seed frenzy. Proper gardeners shook their heads and told me I was dancing with the devil. My crops, they said, would fail, and demons would torment me and cut off my winky.

To placate the gods of non-commercial seed merchants (as if there are any non-commercial seed merchants, you silly hippys), I also ordered several seeds from Nicky's Nursery, and following my first (and only) gardening lecture by the Raven, I also bought some of her seeds. Yes, they were over-priced, and yes, she is a bit mean with the seeds, but I bought them anyway.

So, what results did I find? Obviously, according to the hippys and proper gardening types, the big four suppliers will have failed, and the two smaller companies will have sailed through, because big businesses only got big by getting things wrong! You buy from the man, you end up with bare earth!

So, without further ado, here are my findings...

UNWINS - 97.5
MR FOTHERGILLS - 95.6
THOMPSON AND MORGAN - 95
SUTTON - 90.9
NICKY'S NURSERY - 56.2
SARAH RAVEN SEEDS - 40.6

As a point of note, the Sutton score includes two zero ratings for my failed initial leek and celeriac crops, even though it might have been my error. The subsequent sowings were very successful, but I included the two failures anyway. Even with those included, it still shows that the overall germination rate has been very high! It's also worth noting that many of the Nicky's Nursery seeds were Asian, and might not like the UK. That said, Nicky's Nursery dropped most points on the non-exotic seeds!

Well, you can draw what conclusions you like, but I personally will be using the big seed merchants for everything but the hard-to-find crops. It makes sense, because I'm eating a lot more of their stuff!

  1. Interesting point IG. I tend to use the bigger companies simply because I can get hold of them easily when I've not got time to search online.

    I'm too lazy to work out which of my seeds have done best - but I suspect that the ones that failed were due to getting cooked in their packets in the greenhouse whilst I cleared the ground to sow them! Ho hum!

  2. Holy Christ, statistics?!?!?! Now, I'm really impressed. And, yes, the game was a bit boring, but I couldn't have cared less actually getting to be there. Good times.

  3. All good information. I think one has to have a few encounters with any merchant to truly know how they stack up. Go with what you know and rate them again next year!

  4. "Non-commercial seed merchants" - that reminds me of the derisive huffy smile a colleague, hobby beekeeper, had on his lips when other colleagues rhapsodised about 'organic honey' - "All the little bees only head for chosen organic flowers, haha" he said. Read "Mrs. Fytton's Country Life" with 'Dave the Bread'...
    I like your stats, IG - and share your rating of Great Nurseries, and as with brands I do it with groceries: blind-tests are fine. (My host in Edinburgh told me that some famous great English wine-testers were not able in a contest to distinguish red from white wine - scarves on their eyes, of course.) Don't you have a saying like "to pull the wool over s.o. eyes"? Although: come to think of it: much too hot for that, give me the silk scarf, please:-) Britta

  5. Uh oh...IG, really, you're going to have to change the name of your blog if you keep this up. Math? Statistics? Sheesh. However, your results are interesting. I'm curious, do you know if the seeds from the large vendors, those that had 90%+ germination, were treated seeds? Not that better storage conditions or more efficient distribution methods couldn't account for some of the differences too.

  6. Dear Idiot, I like to think I'm a proper gardener and I can't disagree when I'm called an old hippy, but I buy by variety and value, having champagne tastes and a beer income. My sister buys seeds when on holiday in Spain and they're so cheap I suspect we Brits are being fleeced. Prices seem to bear no relation to production costs but are based on what mugs with more money than sense are willing to pay. Look at the prices in Moles Seeds catalogue. they nearly always win the tender for my order at work, and have an excellent range of fruit, herbs and veg. The best way to store seeds by the way is in the fridge.

  7. I'll buy from anybody who's got a safe seed pledge and is supporting our seed heritage and diversity. I'll also buy from a big company as long as I don't think they're doing anything unethical and I like a particular seed variety they've got. But I certainly don't mind being called a hippie. I am an awesome, brilliant, sexy hippie, and my garden thrives. :P

    My family heirloom seed got down to practically nothing when my grandfather got sick, and no one in the family gardened, and I was living in a high-rise in another city. 25 seeds were finally passed down to me in a jar that had sat on a shelf in a hot garage for three summers -- and I had a 100% germination rate. That's all I've ever cared for germination rates. :D

  8. You did a statistical analysis! - I think I love you more than last time I read your work. You have to rename yourself - Idiot Geek :)

  10. Hi,

    I work for Sarah Raven's Kitchen & Garden and I've just read your blog regarding the seed trials - our germination rates are obviously of vital importance to us and it's very concerning to us that you had such disappointing results. We would really like to look into this further - could you email directly: Jess - at - sarahraven.com with details of your order etc and we will look into this for you. Hopefully we can get to the bottom of this.

Feel free to ridicule, mock, sneer or even say something poignant or witty.

Also, if you have a blog and it isn't on blogger, feel free to post a link too, or I might never find it!

That's all; get on with it!
