Sorry Verdun........I perhaps didn't explain that very well
I've always understood that when you use the Provado, you should remove all flowering stems as the toxin is drawn up thru the plant and hence into the flowers and won't do the bees and other insects much good. So each time I use it, I cut off the flowering stems beforehand.
Having said that, I don't know how long it actually lasts ? I've just dosed several Heucheras in the last few days. As they are still flowering happily and throwing up new flowering stems, I've cut them off and will continue to do so for the next few weeks. I'd be interested to know what the time scale is.
I never find it necessary to use anything for those plants in the ground.....only those in pots.
Sorry for any confusion
