Planting

How to Grow

Choose a location with full sun for the best flowering.
Ensure the soil is well-drained; forsythia tolerates poor soil.
Dig a hole twice as wide as the plant's container.
Set the plant in the hole, with the top of the root ball at soil level.
Backfill, firm the soil, and water deeply.
Water regularly for the first season until established.

Pro Tip

For the best flower show, remove 1/4 to 1/3 of the oldest, thickest stems at the base each year after flowering.

Keep It Thriving

Care Guide

Do

Give it plenty of room to grow to its natural size.
Prune immediately after the flowers fade.
Plant in full sun for the most prolific blooms.

Don't

Don't shear it into a formal hedge; this destroys its graceful form.
Avoid planting in waterlogged soil.
Don't forget to prune; unpruned shrubs become a tangled mess.
