Thereof, what is killing my forsythia?
A dieback disease caused by a fungus occasionally attacks forsythias. The black fruiting bodies of this fungus develop either on the surface or inside the infected twigs. They first invade blossoms and flower stalks, then the twigs, killing them.
Likewise, why does my forsythia not bloom? Many older varieties of forsythia won't bloom after a hard winter or a late spring frost. The buds are simply not hardy enough to survive. However, the most common reason for forsythia not blooming is improper pruning. Too much nitrogen will turn your shrub a full and lovely green, but your forsythia won't bloom.
Similarly, it is asked, how do you revive a forsythia bush?
Remove the oldest, branches as they produce fewer flowers over time. You can also remove any branches that cross over the others or look weak and unhealthy. This type of rejuvenation, which is called thinning, will encourage new branches to form. Thin your forsythia in late fall or early spring before the flowers form.
Why are my forsythia leaves turning brown?
Signs and Symptoms Examine forsythia plants regularly for signs of blight. Spots of blight on the leaves are typically round brown blotches with a yellow trim and may merge together as it eats away at the plant. Flowers infected with blight will wilt and turn brown and may die before blooming.
