Dear All: Winter is coming, indeed certain parts of the country have had snow already. Has anyone tried placing heating cables in the soil under bulbs controlled by a thermostat, to enable one to grow bulbs in a zone where, if in the 'normal' outdoor border without such, they would be killed? I am refering to bvulbs without growth above ground in winter. Would such enable a person to grow bulbs normally grown in higher zones than where planted? Mulched in addition to the cables, such would act as an insulation, as glass in a heated frame. Cheers, John E. Bryan
