We planted this Forsythia several years ago. 

 

See the tall, spindly branches?  I pull them down to the ground and anchor them with 6 inch garden staples.  They root themselves and grow new plants.  We just keep doing that until they fill in the whole area.

 

They are very easily propagated.  Try it!  Start with one plant and tack down long branches to create a hedge.  Good news!!!  The deer nibble, but don't devour them.  It actually works like pruning, encouraging new growth.

 

They are SO beautiful in the spring.  They look like sunshine to me.

 

 

HAPPY GARDENING!!!
