Germination times

seedsowing16

It is seed sowing time again and the first seeds will go in this week. I have a heated propagator that is maintained to about 20c. It is always better to delay sowing a bit if you do not have a bright, frost free place to grow on seedlings once they have germinated. There is no point sowing seeds in a warm propagator if you have to move them out into a cold greenhouse in February or have to grow them on in a dark place where the seedlings will get leggy and straggly. Bear in mind how fast seedlings grow too. Tender veg and flowers cannot be planted out till May in most parts of the UK and Ireland. Some seedlings grow very fast and sweetcorn and nasturtiums will be ready to plant out in just six weeks while tomatoes take longer and antirrhinums and petunias will be among the first seeds you  sow because the seedlings take a long time to start to bloom.

So here are some results from sowing last year. The list is obviously not comprehensive: these are just a random selection of things I sowed. For details of how I sow see this previous post:

https://thebikinggardener.com/2015/02/27/time-to-get-sowing/

I usually start to sow in early February and continue sowing, in trays in the propagator, until April. Most of the seeds are sown the same way, covered with Perlite in about 20c. I have listed them below according to what month they were sown because I thought it might be more useful. I sow the majority of bedding plant seeds in mid March. This list does not include outdoor sowings.

    Thanks for sharing your timings, helpful. The key thing for me is after the thrill of germination they get leggy due to lack of light. Tricky business!

      It can be tricky but the key really is not to start too early. But that is easier said than done when those seed packets are siting there and you have itchy fingers!
