Answer: The foliage should be allowed to ripen by about half before mowing, if possible; there is a compromise at work between maintaining a healthy lawn and preserving the bulbs. The bulbs will also appreciate a higher mowing height, but that too is determined to some extent by your lawn's needs. Over time, healthy bulbs will grow into thick clumps and be even more noticeable. This is one reason why many gardeners do not naturalize bulbs in a closely mowed residential lawn but instead place them, for example, in flower beds or tucked under shrubs where there is a mulch covering rather than grass.
