Forsythia is one of the earliest signs that spring has officially arrived when it bursts into a profusion of yellow flowers from top to bottom, which is also a sign that its time to have those pre emergent herbicides in place. And Forsythia is one of the easiest spring bloomer to force into flower indoors during late winter! When it comes to choosing a Forsythia to plant in your yard, remember there are many different growing types of forsythia, ranging in upright forms growing 8-10 feet high and wide, to weeping selections that grow 5 feet in high and weep over to 6-7’widths, to dwarf selections reaching only 18-30 inches high, to a selection called ‘Kumson’ which is a medium grower with green leaves accented with silver veins. Forsythia will grow in almost any type soil, from sun to light shade, and handles urban planting conditions quite well. Grow as a hedge, mass planting, hillsides, espaliered on walls and fences, or as a specimen. Forsythia flower on previous year’s growth, so prune in spring after flowering is finished.
