They will happily grow and flower with very large clumps of bulbs fully exposed, at the same time, they will happily grow and flower shallowly covered. Top dressing and fertilization wouldn't go amiss. Good winter growth in the year or two prior helps flowering, as does a sudden removal of overgrowth...mechanical removal or fire will prompt substantial flowering. I suspect that most flower buds remain inactive unless conditions are right. Of course, the neighbors/authorities may frown on having a quick trash fire in the Amaryllis bed... Robert in San Francisco, where the Amaryllis lucky enough to be under the dripline of trees (aka fogcatchers) are sending up leaves, most everything else is remaining dormant during the dry Indian Summer...OK, watered and planted winter bulbs are coming up.
