I have always potted-up my large-flowered begonia plug plants in those trays of module cells - 15 to a tray. I know that a few always bite the dust but this year there is quite a variation in size. Some have grown well for this time of year, but some are still quite small. This year I used John Innes No. 2 and earlier on gave them a feed with dilute Tomorite as a little boost. Why does this happen?

Chilly do good cups etc that will keep drinks hot for 12 hours or cold for 24, mine do anyway

I've just bought one of their flasks from church - hadn't realised it was by Chilly until I looked at the box!

As a precaution just sow a couple more seeds to grow on. My last sowings of cucumber will be in early June and they will still produce a good crop later in the year (as good as earlier spring sown seed). These are grown under glass but I guess there would be no difference if grown outside assuming they were of the right variety.
