A good threat works wonders!

I'm usually a quiet, easy going person but there are a few things that really get me going and then I take the appropriate action.
However, there are some things that I can't really do much about apart from issuing a few stern warnings followed by a threat which is always seen through and it nearly always works.
I'm not talking about the actions of people here, nor animals or birds but plants. Yes, that's right, plants. There have been occasions when a plant hasn't done very well in the spot where I've put it so I move it to a more suitable part of the garden and nine times out of ten, the plant does very well.
But there's always one that does it's utmost to defy me. I have had plants that have flourished for a couple of years and then stopped flowering for no reason. I give them bucket loads of TLC coupled with some stern warnings and wait for the next flowering season, but still nothing happens. Then they get the threat. I tell them that if they don't flower next year then I will dig them up and plant something else and this has always worked for me. Last year Nellie Moser (a clematis plant that has large flowers with a dark pink stripe in the middle of the petals) only put out one flower that looked rather pathetic. I never had time to do much with it but as I was tidying it up in the autumn I did tell it that if it didn't flower this spring I would dig it up and put another one in it's place. This spring it was completely covered in flowers and was the most spectacular display it had ever given.
A few years ago Sarah and the grand-children gave me an orchid for Mother's Day and sadly, the last one they had given me did not survive despite me being very careful with it so I knew I would have to be extra careful with this one in order not to upset them. After the first lot of flowers finished I did what it said in the book and it did flower again but not very well. Since those flowers finished it has done nothing! I have fed it and cared for it as the book says and it has grown a couple of leaves in the last eighteen months but no flowers.
It was time for me to issue the threat and so I did. I told it that if I didn't see a flower very soon it would be banished to the coldest window sill this winter or even worse, I would put it outside. The threat of that has shocked it into producing three flower stems that are just beginning to poke out from the leaf base.
So next time you've got a plant not doing very well, threaten it with something horrible because it works for me!
