How long do you leave your toms in there 4" pots?
These are actually in 3" (70c) pots and will normally stay in these to planting out time.
If I encountered a delay for some reason e.g. weather then I might up the pot size.
But I can't recall when I did that last!
do you stagger sowing for continual crops,
With most crops No! salad crops Yes!
I don't grow summer maturing cabbage I tend to grow the late varieties simply because at the time summer cabbages are ready so is lots of more exotic veg!
do you store the produce as well
Things such as Potatoes,Onions, Shallots & Garlic Yes!
More tender stuff I tend to freeze although I prefer eating most stuff just as it is harvested!
