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.
How do you treat twig blight on forsythia?

Can you overwater forsythia?

Why are my forsythia leaves turning brown?
Each is generally introduced through nematodes. Yellow, black or brown spots that form a larger necrotic tissue can mean that forsythia with yellow leaves are caused by anthracnose, one of the most common fungal diseases on ornamental plants. The yellow tissue may also be colonized by tiny fruiting bodies.
What is eating my forsythia?
Weevils. Two-banded Japanese weevils attack the foliage of forsythia chewing on the margins of leaves. The weevils are about one-quarter inch long with a brown pear-shaped body. They lay eggs once a year in dead leaves and leaf folds, and the larvae feed on the plant roots.
How often should I water forsythia?
once a week
Water thoroughly after planting, and keep a close eye on the plant over the following week. Then, give it a good soaking once a week during summer, unless rainfall is plentiful (more than 1″ per week). Established plants can generally get by on less water, but most grow best if the soil remains evenly moist.
Does forsythia like wet soil?
General Care. Forsythias bloom best in full sun, although they will also bloom in partial shade — just not as profusely. They are adaptable plants and will thrive in acidic or alkaline soils, as long as those soils are kept moist. They do not usually suffer from serious insect pest or disease problems.
How do I get rid of anthracnose?
How to Control Anthracnose
- Remove and destroy any infected plants in your garden. For trees, prune out the dead wood and destroy the infected leaves.

How is forsythia gall treated?
Treating galls on forsythia isn’t possible; the only thing you can do once they arise is to remove them cleanly. Cut infected branches off 4 to 6 inches (10-15 cm.) below the swellings, and immediately destroy the infected tissue by burning or double bagging it in plastic.
Do Forsythias like fertilizer?
Forsythias do well without fertilizer and it only takes a little nitrogen to make them skip blooming and produce leaves, so be careful when fertilizing the lawn. You can propagate some of those low-hanging branches by pinning them to the ground for a season, then cutting them from the mother plant.
What is the best fertilizer for forsythia?
