Can my lemon trees go outside now?

[Stevie50001]

So my two Aldi lemon trees coped quite well indoors over the past couple of months...minimal leaf drop but the flowers make a right mess!

I'm hoping I can now move them outside, but I'm not sure about the night temperatures....is it just frost risk or will they not like a less cool temp even?

I wouldn't put them out and leave them, they need to be hardened off first. Put them out during the day for a week or so and then see what the temperatures are like before leaving them out at night.

Could you add your location to your profile please, it makes it easier to give advice.

They like it above 5C, frost is very bad for them, should be inside at the minute, saying that.......

mine have been outside here in Bulgaria for about a month all the time, as Geodome is not finished and I needed to tile the floors and plaster things so out they went

Outside during the day since the start of March, even in the snow the sun was very warm....., many nights had white crunchy ice on the leaves at 6am with -5C on the thermometer in the morning when I braved going outside to start digging, by 10am though the sun has melted the ice and in the sun is mostly 20C to 30C, plants seem fine and growing fast

As roitelet says though, I wouldnt put them out yet in the UK and harden them off a couple of weeks at lest before you try all night, get later every day so it gets a bit colder every day

Haven't quite put ours yet in France (Pays de la Loire) and they will thank you for keeping them under cover for a few weeks yet. As roitlet says, it is always better to harden them off by getting them used to outside temps during the day and then putting them out permanently after the last frosts.

Lemon trees usually do very well and they are quite easy to propagate if you want more. Grow a lot of citrus trees from orange and grapefruit pips and when they are big enough, use them as rootstock for more lemon trees taking the scion from your existing trees.
