Hello.I(Sorry if this is under the wrong topic but I couldn't find a "general" heading).'m very sad that two of my clematis (a montana and an Armandii), each planted next to a rose, have drooped on the same day.  I wonder whether the problem is the chemical I used to treat the roses for black-spot.  Would something like that be detrimental to clematis?Thank you.ByePenny.
