What’s better for young plants:greenhouse or outside?

Hello-just wondering what your advice would be for when to best move plants out of the greenhouse?

I have several seedlings I was hoping to grow into sturdy plants before transplanting but a few things are making me think better to get them into the soil ASAP:
1) Lack of space

2) signs of mildew (I think) on courgette leaves

3) ‘frizzled’ leaf edges on anise hyssop seedlings 

4) Aphids (no photo necessary)

do plants grow faster and more healthily out in the open? I remember putting some artichokes into the ground last summer and they pretty much doubled in size within 3 weeks...

... and any tips on any of the above problems gratefully received 🤞

    I don't keep anything in a pot longer than I have to. As long as they have a decent root system and healthy top growth, as soon as the temperature is okay for them, out they go!

    I would say it depends what your mollusc situ is like. I keep mine on as along as possibly so they will survive attacks.
  • Great, glad to hear it thank the cat, would love to free up some greenhouse space. Mollusc situ not too bad fire, pretty average I’d say-worse threat are the ever-multiplying aphids, hoping they won’t spread as easily outside 😬

    It's such a touch and go time elspeth, but I think they speak to us. On the one hand we are thinking will they cope in the cold frame or the ground after being cosseted, and they are saying "look at me, I don't feel well, let me grow" 

    We worry about late frosts especially right now, but I am planting out most things apart from tender annuals. I am keeping my fingers crossed for them of course.

  • Think some of mine are definitely saying ‘get me out of here’! The greenhouse is ingested so hopefully they’ve not been too pampered. Maybe too early for others...

    At this time of year a lot of mine are outside by day and inside at night ... getting the benefit of the sunshine and fresh air and protected from the chills at night.

    It takes a long time in the morning and evening walking backwards and forwards but it's worth it  :)

  • Hi dove, thanks-I’ve put about half of them out and am using trays to save time-so many little pots! Still chilly in Scotland in the evening at the moment so will cart them back in tonight...

    A couple of years ago we had a young teenage niece staying with us for a few weeks in late April and May ... she came in very useful carrying trays of pots in and out ... she remembers it well  ;)
