Marigolds Question

[mrdinkle]

Hello Flower People.

I have germinated a tray of marigolds (half french and half african) They only have their seed leaves at the moment and are literally half a cm to a cm tall.

My question is; Will it be ok to leave them in the greenhouse overnight? I have a paraffin heater which I light when frost is forecast.

Hello MrDinkle, your marigolds will probably be OK unless it is really cold. I lost a tray one year. Are you using fleece. I highly recommend it for covering your plants overnight. The light weight stuff will protect againt 2 or 3 gegrees of frost and the heavy stuff gives 7 degrees of protection. In cold spells it can be left on for days at a time. Well worth the 2 or 3 pounds it costs. And you can use it outside in the same way.
