Progress at last!

The seed sowing begins ...

This month I've been pondering on why some seeds fail and the relativity of time ... days pass quickly when enjoying yourself but waiting for seeds to germinate? Not so much. Having sowed trays of peas and broad beans late in March (and loads more seeds throughout this past month), I check daily for signs of life and get excited when tiny green shoots poke up above the soil. (Hello cape gooseberries and ahoy Pak Choi!) This month has been more of a waiting game though and I’m feeling the pressure to get plants growing and planted out in a timely fashion.

The weather hasn't helped ... after a blast of sunshine early in the month, the skies then became grumpy and rather chilly.  This was not ideal for the bean and pea seeds growing outside in the shelter of my tiny balcony. I start hardier seeds off outside as I like to keep windowsills indoors clear for the deluge of more tender seeds to come. Sometimes my optimism is misplaced.

Earlier in the month, having monitored daily for the appearance of broad/fava bean and sweet pea seeds, I began to wonder if they were all duds - and then it dawned on me to check the label I’d put with the plants. Even though it seemed like ages since I'd sown the seeds, it had only been a week and temperatures were chilly. Doh! 

However, sigh of relief, after a respite indoors on the kitchen windowsill, shoots appeared within a few days; at 2 inches tall, the plants went back onto the balcony. And now I have ten sturdy little plants planted out and growing well.  (There were supposed to be fourteen but four seeds did fail to germinate, such is life.)


Why so few plants? Well, the broad beans were destined for two 12 inch wide rows in the Abundance Bed which is my project this year. I decided to dedicate an area of the veg patch for an Abundance Bed after reading Huw Richard's book 'Veg in One Bed' (reviewed in December); I love being told what to do and when. Sticking to the book's plan of action, my broad beans were planted out mid-April when the plants were about 4" high.  Whew ... just in time! 

But why do seeds sometimes fail?

Sometimes the seeds are just too old if kept from year to year. Once packets are opened, seeds start to deteriorate and the energy stored up for germination is lost - basically, they run out of puff. I’ve started marking new seed packets with the date that I opened the foils and pay attention to the year packed as well as the ‘sow by’ date.

Some seeds will last longer; I’m sprouting a few old orca and Borlotti beans in cotton wool to test their viability rather than wasting seed compost. I first saw this done with slow germinating seeds like parsnips, tried it for myself and it worked. I’ll plant the seeds when (if!) signs of life are seen. 

It's guesswork knowing the best time to sow seeds; the sowing timelines on the packet caters for gardens at all extremes of the country but it is only guidance. Too cold and they’ll struggle to germinate. Too early and they struggle for light. Too late and annual plants don't have enough time to fully develop.  That's particularly true for chillies (always hit and miss for me) but I've finally got my tomatoes, cucumbers, chillies, leeks and peas sown.  All in modules, destined for the windowsills - the first lot for the warmth needed to germinate the seeds and the peas to (hopefully!) keep the mice from eating them. 

I've sown runner beans, sweet corn and french beans into root trainers this morning; squash and courgettes are next - maybe a teeny bit later than usual but with slightly warmer weather now, they should quickly grow into strong plants. Fingers crossed, eh?

And the sweet peas? Well, after three weeks of daily checking, a few tiny shoots popped their heads above the soil, just fifteen out of the 30 tubes sown. That'll do.  But lesson learned: noticeably it's the freshest seeds that have germinated (plus a few from last year) so some ruthless seed culling is needed! 

So, as ever at this time of year ... onwards!
