I feel your pain. Resolva is very effective but it can be a bit tricky if the cellandine is surrounding plants/hedging plants. Last year I cut my losses and sprayed the whole area, which also killed some plants but this year, it is much better although not completely gone yet. I've sprayed in between the hedging plants but I think it's a bit risky now that the hornbeam is showing buds. Personally, I don't think digging it out is very effective because you either have to take a shovel of soil out of the plot or risk missing some of the roots. In a very long winded way, I think I'm saying, spray wherever/whenever you can and keep fighting the fight.
