Hi All,

I've inadvertently managed to spray some glyphosate on some bulbs (hyacinths
I think) and am wandering what effect it will have. It's killing the foliage

yes, it's a translocating weekiller. Sorry!

Probably. Although it is absorbed via the leaves, it affects all parts
of the plant.

Glyphosphate did not kill my Scilla Campanulata (Spanish Bluebell) when I tried to reduce their numbers last year - they
are mostly back again this year, choking everything else as usual.

My guess is that at the time you applied the glyphosate there were
already either newly formed bulbs or seeds underground with no
topgrowth, so they could not absorb the glyphosate.

Very likely. A few very waxy plants can resist glyphosate but not
reliably. If they show any signs of premature yellowing or die back it
is probably terminal.

I have known holly seedlings survive, and I know some succulent growers
who swear by it for removing couch grass from pots of nasty spiny plants
but I wouldn't risk using it for this task myself.

The only thing you can do if you hit a wanted plant with systemic
weedkiller is lop off the contaminated bits ASAP. Translocating
weedkillers are very effective and kill the whole plant.
