I'm growing tomatoes from seed, and have just transplanted the seedlings into individual pots. It doesn't say on the back of the packet, or in my book, whether the pots need putting under a propagator again once potted, or to leave uncovered. Please advise.
They are cherry tomatoes, Garden Pearl, that I'm planning to eventually grow in a hanging basket.
Where are they? They need warmth and light. If they're indoors on a windowsill then no, I wouldn't cover them, but I might take them off the windowsill onto a counter or something overnight if it was likely to be particularly cold.
If they're outdoors in an unheated greenhouse then you'll need to find some way of keeping them a bit warmer overnight - mine go in a cold frame inside the greenhouse (so 2 layers of glass) which is shut up at night and then has a thick blanket over it. Obviously it all needs opening up in the day so they don't cook!
After transplanting, you need to leave them somewhere cool to warm - not too hot - they need time to recover before the roots are stable and able to draw up moisture to replace what will be lost through the leaves. Put them somewhere too warm and they will die.
I have a shady shelf where all my newly transplanted seedlings for for at least 3 days, preferably a week. Stuff usually gets transplanted one Sunday and moved into the warmer areas a week later.
Ok thanks funky, something else to consider. Sounds like our bedroom/living room might be best then, as they are the cooler rooms in the house.
The house is doubleglazed and a new build (bit small) so doesn't get too cold, and we have a conservatory behind the kitchen. The back of the house is a suntrap, so the window ledge has been the perfect place to start growing from seed
Ok, so having read both pieces of advice, thanks takver and funky, I've decided to keep them cool and shaded in the front bedroom for a couple of days, then move them back onto the windowsill afterwards. Meanwhile, I'll keep a close eye on them.
