Soil for Forsythia

Tolerant of most soil conditions, but prefer moist well-drained soil with a pH of 5.0 to 8.0.

Planting Forsythia

The only times to avoid planting forsythia throughout the year are during frost or height of summer (water regularly to establish with summer planting). Plant forsythia in an area with full sun to achieve maximum flowering. With sizes ranging from 8' to 10' tall  and 10' to 12' wide you will want to plan your spacing accordingly and leave plenty of room for growth. 

Irrigation for Forsythia

Forsythia thrives in soils that are slightly damp to moderately dry. Areas prone to waterlogging are not best suited for forsythia. Extended dry periods may require watering, but supply slowly due to the plant's shallow roots.

Deer Resistance & Pollinators

Forsythia is considered deer-resistant once established, and Japanese beetle resistant.  Keep an eye on your new growth, as they tend to be a favorite for deer. 

Fertilization for Forsythia

Forsythia will not need additional nutrients in most gardens, as long as it is planted in a nutrient-rich, humus soil or fertilizers have been added to the soil. 

Pruning for Forsythia

After forsythia flowers in the spring is the optimal time to prune, and will help develop fall buds. Since forsythia is a rapid grower, you will want to prune regularly to maintain a manicured shape.
