For New Jersey gar­dener Barb Stiehl, start­ing flow­ers from seed has be­come se­cond na­ture. As she puts it, “From the moment the seeds ar­rive, I just march along.”


• Us­ing a seed-start­ing soil mix­ture, she plants seeds in cell trays with clear plas­tic cov­ers that hold in hu­mid­ity un­til sprouts ap­pear.

• In her base­ment, she po­si­tions the trays on heat­ing mats be­low LED and flu­o­res­cent light­bulbs on timers sus­pended by drop chains to ad­just the height as the seedlings grow.

• In mid-april, she be­gins mov­ing seedlings to the un­heated green­house to in­crease the light and strengthen them. If very cold weather ar­rives, a heater is used to warm the green­house.

• Seed trays are moved out­doors when the weather warms.

Among Barb’s thrifty se­crets is her plant-la­bel sub­sti­tute. She uses plas­tic knives to la­bel seedlings such as Al­ter­nan­thera ‘Pur­ple Knight’, Vista Pur­ple salvia, and an­gelo­nia. “It’s so much less ex­pen­sive than buy­ing la­bels,” she says.
