Sowing in greenhouse
Im a bit stuck as i am new to gardening. Bought a plastic greenhouse, walk in one, but what do i put in it? Can i sow seeds in propogators with lids on/off? Like Lavender, aqualegia, lettuce, tomatoes, anything really? Spring flowers that come in spring, if i sow spring stuff now in greenhouse wont they pop up to early and die? Can i grow anything i want in a greenhouse now?
Scotland where it gets really cold.
