oh you have brought back memories my lovely DH used to grow and show the Giant Chrysanthemums, and enter them in shows, in fact I have just recently stuck one of his Chrysanthemum Silver medals on the Arbour I have erected, the other Silver medals are being given to Grandsons and other member... and yes earwigs a big prob...we used to put Vaseline on the canes..to stop earwigs climbing up.also once the bud is showing a tiny bit of colour you can put what they call Flower bags on and sort of blow the bag up, place on the bud so it is inside and tie it with twist tie, this keeps out the bugs etc and blackfly is a big prob with Chrysanths..good luck
