Just a note. My wife received a pack of over 30+ plugs from a well-known UK nursery who shall be nameless. They were (believe me) minute and most looked on their last legs. We both sighed with resignation and just left them to dry out and complete their living exit from this world in a respectable fashion.
They were so tiny that they hardly deserved a decent burial.
2 weeks later (2 days ago), I am tidying up the greenhouse and found that rather wretched package and was about to bin the lot.
1/2 dozen of these wretched micro-plugs were still green although absolutely bone dry. They had no sense of reality!
I’ve not the slightest idea what they are.
Being the softy that I am, I eased them out of their package and set them around a clematis in a large pot and gave them some H2O.
I wish I had the grip on life that they have! The little devils are still green and look as though they may actually (one day in this or the next decade or century) come to something.
Sometimes, we all know, you have to dump failures and learn stuff.
But in some cases -
Never say die until things are dead
