I am new to gardening. Not sure if this is a silly question or not. At the end of the summer when the flowers in the tubs have died can the compost be saved and used for the next year?

A very sensible question! I also save mine - in fact I leave most of the compost in the tubs, and the following year take off the top couple of inches and add fresh compost . . . it seems to work.
Welcome to GoY from me too.

I do the same as Mel. Make sure that the plants had not caught any diseases, check through the compost for nasties (grubs and weeds) and add a fertiliser of choice to replace that used up by this years plants.

Thank you the 3 of you will certainly do what you have all suggested.

It is certainly not a silly question, and welcome to gardening and GoY.
I always save mine, as long as the plants have had no problems. I have a look through it to make sure there are no vine weevil grubs. Before I plant up the following year, I add plant food granules. Others may disagree, but it has always worked for me. Good luck!
