Those temperatures sound warm enough, but won't it be expensive at this time of year?

But I think it is rather too early to be sowing nasturtiums and morning glory as they are quite fast growing and will be wanting to be planted outside long before it's warm enough. Same with tomatoes, unless they are greenhouse ones.

Which sort of marigolds, French or English? Too early for French, not hardy. Will you have room in the greenhouse for all the begonias, geraniums and dahlias once they all start growing bigger and needing to be potted on? They can't be planted outside until after the last frost, 2nd half of May.

I don't sow anything until March, but I don't sow begonias anyway, I buy plug plants as they take a bit of time, same with geraniums.
