Recently, I’ve been asked about the care of Forsythias. These are a bright, yellow Spring flowering plant that herald Spring. When in bloom, they are also a great reminder that it’s time to prune your roses. When the blooms are gone, they create a hedge or tall, background plant for garden beds.
It is easy to care for Forsythias. They only need an annual pruning to keep their shape, increase air flow, blooms and rejuvenate the plant’s canes. You want to follow the Rule of Thirds to prune Forsythias. Remove the first third of the canes entirely. Cut them down to the ground. For the second third of the canes, prune them about a third the way down. And the final third, leave the canes as they are. If you want a more compact plant, you can pinch out the tips of the canes. Please let me know if you have any questions or need clarity.
