I originally wrote this last year but now in April I have checked my Chrysanthemum plants in the cold greenhouse and find I am infested! So it must be worth a rerun. Evil weevil grubs eat roots and tubers of your favourite plants. My tuberous begonias were attacked and destroyed by these pesky pests. It is the white grubs that cause the damage as they eat roots and tubers throughout vine weevil puberty to become small black beetles. The beetles will nibble the edges of leaves but it is the laying of eggs that ultimately cause the problem. The eggs become grubs and your Cyclamen, Primula and Camellias become grub for weevils. Pot grown plants are most susceptible to attack but this pest also affects other plants such as Fuchsias, Gloxinia and Strawberries.
I am willing to use chemical treatment like Amazon’s Pbi Provado Vine Weevil treatment, if the squashing of the grubs is not good enough.

Red, White and Blue the patriotic colours of the Hydrangea are augmented by pinks and purples like H. Ayeshia above as a variation on those themes. Flowering from mid-summer these shrubs give a magnificent display with very little effort. Did you see Hydrangea maritima on seaside holidays in large displays of sugary pink and sometimes blue.
My Rhododendrons were in full bloom when a late frost caught them quite badly. Winter has been wet and mild but if the USA is anything to go by hard frosts may still be on the way so look after your early flowering Rhododendrons.
