Flowers by sowing month (adjusted for germination)

This chart shows the number of flowers for each month’s sowing time – but it has been adjusted to normalise the results for germination and seedling survival rates. This removes the effect of where more seedlings were lost or didn’t germinate in January, which immediately puts this month at a disadvantage. With the adjustment applied, January just pips October to the lead (the unadjusted numbers showed October miles out in front). This demonstrates that if you can get all your seedlings through the winter and into the ground, January, October and March are the months to sow. Of course, in the unadjusted chart, January was much further down the chart, indicating that this time is at greater risk of losing more seedlings or has a lower rate of germination success, but the seedlings that germinated and survived will flower well. Lastly, it’s useful to note that adjusted or unadjusted, November always comes out with the least number of flowers – so is clearly the worst month to sow your Sweet Pea seeds!
