When can you cut down allium when they are done blooming....do you have to wait?
The flowers on my allium are always beautiful, but the leaves are yellowish and unattractive even prior to blossoming. They are planted in full sun.
Allium really don't have many growing issues generally. Proper watering and light fertilizer are generally the biggest requirements.
Did the plants suffer a cold spell after leaves had erupted? Did they have some wet weather or a dry spring?
I suspect something weather related caused some leaf or bulb stress but not enough to hurt the blossoms.

I have a lot of foliage with the alliums that is flopping on the garden. Should I cut it back?
Floppiness seems to be an unfortunate trait of alliums. I have seen recommendations to plant it among other perennials, such as tall hardy geraniums, for support (or a clever disguise).
I wouldn't recommend cutting back all the foliage because your bulb's vitality depends on it. Your leaves absorb sunlight which is needed for photosynthesis which the bulbs need to create food to survive through dormant periods.

You only need to dead head the plants if you do not want them to reseed.
