By Carol Stocker...I will be on line live this Friday from 1-2 p.m. to answer you gardening questions.Memorial Day Weekend is the traditional weekend for planting tender vegetables and flowers. Local nurseries and garden centers will be well stocked. Plant seedlings and plants at the level they are growing in their pots. But plant tomatoes two inches deeper than that to encourage roots to develop along the buried stem. Plant bean seeds two inches deep and a foot apart.
