Today I issued an edict to my husband, Mike. "Thou shalt purchase no more supermarket salad. We now have our own crop on the roof top veg plot."
My efforts to have salad all year round can't be said to have given us enough greens through the deepest winter months, principally because a) I didn't plant enough and b) I forgot to take enough account of the slowing of the growth process that happens from November to February.
The Johnson's Mesclun mix I planted in October and left growing with very little attention in the growhouse has finally come to fruition.
The saladini mix I made myself and planted in January, produced a rather weedy crop of microveg, in about six weeks. The same mix planted in February, looks much more sturdy.
Next winter I will start my winter veg off earlier, so that it has already grown by the time winter sets in.
It seems the secret is that salads are happy to sit during the winter months, but they will only grow slowly. So there's little point in succession sewing for winter. Get it all in by the end of August and then you can crop right through winter.
