Tomato feed killed my clematis?
I recently bought some tomato feed for my clematis. i have three: one well established, planted in a pot outdoors, and two from last year, still small but already flowering in the conservatory. i had fed the bigger one some tomato feed before (bought from wilko, generic brand, can't remember), no problem.
a few days ago, i bought a bottle of verve tomato plant food concentrate (with seaweed and magnesium) and poured a bit on the three plants. i did not dilute, but then again i didn't before when i fed the bigger pot. all three plants started to wilt and die. the leaves are flacid and darkened, the stems on the smaller have all collapsed.
it probably has to do with the feeding, as they're were doing fine before. i only fed them because i was told it would improve flowering, but i'm now heartbroken that i may have killed them. is there anything that i can do to reduce damage and maybe save them for next year or is it hopeless and i should bin them now? any help much appreciated, thank you.
