To water, I like the syringe idea best, ....but don't have one. What about in the initial wrapping of foil, to include near the stem a short length of tubing (like main drip or aquarium, or even 2 inches of garden hose) through which you could pour/funnel any necessary water. Keep that sealed/corked when not in use. Of course that would detract somewhat from the 'easy' aspect.
Where can one get a large syringe?
