Bulbs and Weedkillers

Hey Joe

I have had several Crinum bulbs recover after being roundupped though I was
not trying to spray them but attempting trying to spray around the plants
caught them in the drift. They recover for the most part if they are mature
plants. Seedlings experience higher mortality and mature plants often do not
bloom for a year or two after exposure and it is possible to kill an
irreplaceable mature plant & the losses where high enough that I would not
recommend it. For extreme bed clean up, I would recommend mowing or cutting
Crinums to the ground removing foliage along with the weeds. Once the
foliage is removed there is much less surface to expose to the herbicide and
it is easier to spray roundup without affecting the Crinums as long as it is
done when the air is still... This is still a stress on the plants but they
recover from the mechanical damage far better than they do from the chemical
