Hardening Off Help

Orchid LadyOrchid Lady Posts: 5,800

Hi All, 

I have several plants I don't know what to do with now, all are inside and I don't know whether I should be moving them to the greenhouse, move them outside or swap them about i.e. out/GH during the day and in at night, please could someone give me some guidance.






Morning Glory

Chillies (Cherry Bomb)

Yesterday I planted out my Hostas and hardy geraniums so I'm hoping they will be ok.

Thanks in advance.

    I am putting my Tomatoes in the polytunnel during the day and bringing in at night as we are having cold night in the South and the temp change would be a big shock to the system.

    As the nights warm up I will leave them in the poly overnight and maybe wrap in fleece if its a bit chilly. Its a gradual progress and you just have to keep an eye on the weather.

    For plants that are going to be planted outside I start off by putting them out during the day then if the forecast is ok for night time temps I will leave them out in a sheltered spot and in a week to a fortnight depending on their rate of growth I will plant them into their final positions.

    It's dependent on their frost tolerance,plants such as cucumber, tomatoe, courgettes will be really knocked/killed by a sudden frost so I dont plant them out till last week of May/first week of June.

    Thanks Scroggin, that's made it a bit clearer. I guessed the toms and cucumbers would be different as they are not outdoor varieties.  I really don't want to kill them all off image

    I am not sure about the rest but Morning Glory definitely can't go out yet. I put mine out in the unheated greenhouse and they have stopped growing and gone a really sad yellow colour. I have another lot that are still in the house and are growing like mad. I have since read up a bit more and apparently they do not like temperatures below 10 degrees at all. I think next time I will sow my seeds later.

    Oh Verdun......it's a good job someone knows what they are doing, or were you trying to sabotage my growing efforts on purpose image

    Thanks Verdun for the info that was correct and Sprig image Sowing some more Morning  Glory that have arrived today and keeping them on the windowsill image

    If your toms and cucumbers are indoors they will benefit from the added light they will get from being in the greenhouse during the day. At the moment its warmer in my poly during the day than indoors and obviously more light, its a bit of a faff but if you bring them in at night they will benefit from the extra light.

    It is warmer in the GH Scroggin, it's about 30c, they are on trays so not too much 'faff' I will give it a go.

    I actually cross posted with Verdun so did not know I was contradicting until after the event! You will probably find your new batch of Morning Glory seeds will end up better anyway. Mine are getting so big now they are a bit unmaneagable inside, at least yours will be a sensible size when the weather is good enough to put them out.

    I've not sowed my Morning Glories yet - they get away much quicker if you wait until the weather is warmer image
