Can I sow in an unheated greenhouse ?
« on: March 04, 2011, 18:34 »
Got my new greenhouse lean to up and ready but no heater. Can I start sowing things now like Beetroot, Radish, Onions (sets in pots), Chard and salad ? I know the temp isn't yet right for germination but having the seed ready in the pots won't do any harm I hope.

Seed won't just sit there waiting for the right conditions to pop up, it's quite happy sitting there quietly rotting.

Having said that, the onions will be quite OK in pots and you could try an early sowing of radish & lettuce, the seed is cheap enough.

You have to bear in mind that we could have a few real cold nights yet.
Did it really tell you to do THAT on the packet?

Seeds are SOWN, planting's for plants (and bulbs & tubers)!

I have broad beans germinating in my cold greenhouse.
I sowed them a week or two ago and tipped one out today to see what was happening so I know they have not rotted.
I also have cabbage seedlings coming up.

I sowed a few lettuces and peas but have not seen anything happening with them yet.
My greenhouse is not in the best spot as it does not get sun in the afternoon.
On sunny days I put my tomato seedlings out for an hour or two.

When you sow your Peas, B Beans, Cabbage, do you use Innes number one or normal multi purpose ?

 I use multipurp, but if it's really twiggy i'll sieve it a bit first

I'm growing lettuce and spring onion in mine. They seem to be doing well.

I went out an bought John Innes Number one for seed sowing and Multipurpose for later potting on. I thought the Number one gave your seeds a better start as they don't need food at the first stages of growth.

Soaking my peas and beans in a tray of water before planting to get them sprouting.
