Too hot for cucumber to germinate?
Hi,
I am planting my seeds very late (it has been an unusual year) but I am trying to grow Burpless Tasty Green cucmbers and yellow courgettes. A couple of weeks ago (I think) I planted seeds in pots and put them in an outdoor mini-greenhouse; one of those fancy plastic bags over a vegetable rack. Both courgetttes have germinated and are aparently doing well. None of the three cucumbers have shown any sign of germinating. I have put another couple of pots in with cucumber seeds but I was wondering if it was too hot. The courgette packet says approx. 20-25 C and the cucumber packet says approx. 15-20 C. I was wondering how critical this temperature was likely to be, and also if the watering regime was not favourable. I have them in a plastic tray which I fill irregularly (i.e. when I get the opportunity - could be once a week). This keeps them from moist to distinctly wet. The courgettes seem to love it. I am now wondering if I should plant some seeds in pots and just leave them outside, as we seem to be in 15-20C most of the time at the moment. If they are just slow to germinate, of course, I may end up with far too many cucumber plants :-) So - too hot, too wet, or just too lazy to germinate? Cheers Dave R -- |

Cheers Dave R -- If you have trouble germinating any seed of reasonable size - cukes are big enough to see what you're doing then try chitting them between sheets of moist kitchen towel. I myself make "slides" consisting of two margarine\spread tub lids, with the folded kitchen towel in between, held together with elastic bands. Check and remoisten with a mister daily if necessary. As soon as the radicle root emerges, plant the seed root downwards in a pot with the seed half buried. IIRR cukes have an emergent cotyledon so the seed will split and be pushed upwards to form the first pair of "leaves" - for photosynthesis purposes anyway. Take care not to damage the root, so make a largish hole place the seed against the side and firm the compost from the other sides inwards. michael adams .... |
