PGKVET mentions the exorbitant cost of T&M seeds .. most other UK located seed houses are catching up fast .
There is a solution that initially looks very expensive but over a couple of years works out exceedingly cheap and gives a heck of a lot of seeds .
I discovered the FRANCETTI ( sp ) range of seeds .
Whilst equaling T&M prices & in some cases exceeding them , the amount of seed is hundreds of times greater. So providing you set up a simple system to keep the opened seeds cool & dry ( sealed air tight Tupperware type box or am large screw top jar in the bottom of th fridge is what a lot of folk use ) , you can take advantage of the viability life of the seeds that usually lasts for five or so years to give you at least 75 % germination .
I have a seed viability list that I got off the internet five or more years ago . Will look for it innth log cabin tomorrow if anyone wants to see if it is still there .
The Francetti seeds seem to be true to the viability life list , but a lot of the UK seed houses seeds don't .
Perhaps because they bulk buy for the next five years in one go & release a few each year
As a general rule though , with the exception of parsnips you can add a year or two to the indicated use by date on the packets of the UK seeds & mark your estimated use up date on the bottom of the packet in marker pen .
A way of finding out if the seeds are viable is to cut up ten 1/2 " square of kitchen towel , set them on the inside of a Pyrex dish lid , add a table spoon or so of water to the lid . Now put one seed on each square , ensure the square is nicely wetted then put the body of th dish over the lid and slip it in the airing cupboard .
In a few days you'll know the viability if you multiply the number of germinated seeds by ten .
If it is bigger seeds like peas & beans wrap the seed in a couple of inches of 1/2 " wide cut kitchen towel strip and add six or so tablespoons of water to the lid .
Carrots for instant :-
You're luck to get 200 T&M seeds Francetti give you about 2500
Tomatoes 50 against Francetti's 750
