The Right Time To Grow

...

With high day time temperatures, the sun factor increasing the warmth in the greenhouse well above the the teens and night time temperatures in the minus…. I could almost do a piece here on autumn colour but… it’s March and there are no leaves on the trees. So instead the resulting problem and piece is one of possible woe rather than beauty and colour.

I know that around 12 – 14 degree celcius is what makes [almost all] plants start to grow and the reason this is so important is that I’ve just started my seed growing for this year.

The temperatures in the greenhouse [as you can see above] are more than enough to make the seeds germinate. The problem is that when the little baby seedlings pop out from their store of food [the seed] the low temperatures at night time can come along and literally whack them.

In theory, the water in the plant cells expand when it freezes and this bursts the cells. Put simply the affected cells are dead. That’s not so bad if the plant is an established hedge but for a weakling and barely days old seedling with a very thin outer skin that is so easily penetrated, there is no way back.

I hear you say, I could have waited. Kept my eye on the calender or clock. Been a little more patient and waited a bit longer before I started my sowing campaign. I could even have bought myself a greenhouse heater…. but where’s the fun in that.

I’ve waited this long, this year, to get outdoors and get grooving in the garden… Similar to the Irish potato farmers and the season they’ve just had, I’ll take my [very well calculated] chances against the elements and hope I’ve simply got a head start. If it doesn’t work out… I’ll scatter my seeds and try again.  😉
