Rust on hollyhocks is almost inevitable, and personally I would not worry about it, so don't buy stuff for that if I were you. Vine weevil is another thing, you probably do need to treat that. It may only be affecting your clematis just now, but can get anywhere. I do not use chemiclas very much ( I make an exception with provado for lily beetle, as I grow a large amount of those), but some things do call for special action. If your plant does have clematis wilt, don't worry - you need to make sure the clematis is in the pot very deeply, then if you do get it (or rather the clematis does!), cut it down to ground level and it will come again next year. The viticella and other smaller flowered ones don't get it, so that might be something to think about for the future. Large summer flowered ones in pots can struggle, but the smaller ones, especially those bred for container growth, are a jolly good bet.
