I took another photo 8 days after the one in the previous post and was surprised at how much they had grown. Maybe I’ll get round to repotting the 5 small ones this afternoon if it warms up a bit – as no train to see today!!
As they grow, the plan is to move them into pots the size of the one filled with water, top right of the image, but for the next year or so I think they’ll be OK in the medium size pots. Time will tell.
