Q.My Nasturtium Seedlings Have Gone Very Tall (growing On A Windowsill) – Is It Too Soon To Put Them In The Garden? Live In NE Scot
I planted a whole packet of seeds – some in pre-prepared sponge modules and some in small peat pots and put them all on windowsills. They have grown quickly and gone very tall and skinny. sorry, I don’t have anyway of getting a photograph.

I'm not familiar with the climate in your country, but it is fine to plant them as soon as all threat of frost has gone. It is worth noting that they do not transplant well, at all. Have care not to disturb them as you transplant.
Here is an article that will help you to care for the plant: https://www.gardeningknowhow.com/ornamental/flowers/nasturtium/growing-nasturtiums.htm
Nasturtiums are not frost tolerant meaning that any frost is likely to kill fragile seedlings. On the other hand, leggy plants aren't good either. Can you put them in pots that you can cover with cloth overnight or move into a shed if frost is in the forecast? Forecasted temps less than -2C (a freeze) should prompt you to bring the pots indoors overnight.
