  1. 1

    Prune your forsythia at the right time of year. The blooms will spring up from the old buds and stems from the year before, so you must trim these bushes right after the spring flowers have died.

  2. 2

    Cut your forsythia branches back about 12 inches to 2 feet depending on how fast a growing season it had. If your bush is a few years old, it is best to thin it out at this time by cutting some branches down to only 3 or 4 inches long. You should trim out about 25 percent to 30 percent of these branches to encourage strong stems on the forsythia.

  3. 3

    Trimming your bush back to a strong leaf joint or bud is important according to the website. With proper maintenance, your forsythia bushes will bloom for years to come.

  4. 4

    Use hedge trimmers twice a year if you have a hedgerow of forsythias. The last trim should be in late July or August.
