They are frost tender and will get damaged or killed by it.
That said, all plants benefit from a gradual transition when they are being moved to new conditions, as this allows them to better resist any shock that they could experience, by allowing them to make adjustments, at their own pace. Whether, indoors to outside, changes to humidity levels, artificial to natural light, warmer to colder etc. When moving plants, aim to give them a few minutes a day, gradually increasing over a week or so. Ideally you'll not start to move them when conditions are very different to what they've had and when the new ones are very unsuitable.
They won't have any experience of national sunlight yet, so it would be better to start them in light shade, if possible. You could give them 1/2 an hour the 1st day, 1 hour the 2nd, 1.5 hours day 3 etc.
Keeping them potted during the transitional period will prevent shock to them with a new growing medium too.
OP, i didn't see where you are based, so outdoors transition will vary by location and the prevailing weather.
Obviously indoors they may get a bit etiolated, in their stretch for enough light and outside would be great, if only they could easily cope. It's really better if you can prevent an early shock, by suddenly moving them outdoors 24/7, so that they remain vigorous growers.
For much of the UK, I'd be looking to start transition in mid May. Again, it will be weather dependent and could be helped by some light protection, from cold winds, heavy rains etc. |
