A few days ago I planted up lots of different veggie seeds. I did some beetroot, broccoli, sprouts, three different cabbages & some parsnips. I used left over seed from last year & beyond & have since read on a seed packet in a GC that I should only use fresh parsnip seed. Is this right? I know parsnips are really slow to germinate & I don't want to be waiting a long time for nothing to happen. Also, are any of the other seeds I've done going to need redoing?
Fanks in advance. :)
The viability of even fresh parsnip seed is sow low that it probably isn't worth risking using old seed. I would resow if I were you. ;)
Parsnips and onions are both best sown in the first year,other seeds will germinate well for a number of years,any of the cabbage family many years.
My 100% germination of 1994 courgette seeds prove that old seeds can be OK
Old sweetcorn seed are also very unreliable ...
I have used lots of very old seed and have excellent results.
