you can try anything you want...

its a bit late.. at that size.. but what the heck ... large plant and high heat.. is a lot of stress .... thats why we would prefer them smaller.. when its cooler out ...

regardless .... i would do it on a rainy or cloudy day ... watering deeply the day before... and taking a big shovelful of soil with it .. dig new hole first ...

if they are seedlings all jammed together.. well.. leave them jammed together.. and move the clump ....

i learned EVERYTHING... by trying ... no WWW back them ... so what if they die ... lesson learned.. and not forgotten ...

and no one said you have to move them all at once.. try one at a time...

ken

ps: plant type makes no difference .... its more along the lines that it is summer.. and this was an early spring thing ...
