Best to use Sevin.........fill a 5 gallon bucket.........put the liquid in and stir......drop the whole plant inside............keep it there until the bubbles stop you might need to dip all the flowers in pots. Keep children & pets away while you are doing this...and wait for them to dry off before letting them back out where you have these plants dripping........good luck with your plants. Please don't put this down a drain....use the rest on other flowers in your garden. Chemicals are not good for septic systems or near drain fields.
