How to prune Forsythia

Forsythia, also known as golden bell, is a beautiful shrub that showcases bright yellow flowers in the spring. Pruning is an essential task to maintain the health and appearance of the plant. Pruning not only controls the growth of the shrub but also encourages more robust flowering. In this article, we will guide you through the process of pruning forsythia.

Firstly, it is important to mention that forsythia blooms on old wood, meaning the buds for the following spring’s flowers develop on the previous year’s growth. Therefore, the ideal time to prune forsythia is right after it finishes blooming in late spring or early summer. By pruning at this time, you will avoid cutting off next year’s flower buds.

The first step in pruning forsythia is to remove any dead or damaged branches. Look for branches that have become discolored, dried out, or broken. Using clean and sharp pruning shears, cut these branches all the way back to their base, close to the main stem.

Next, thin out the plant by removing some of the older, thicker branches. This process allows more sunlight and air to reach the inner parts of the shrub, promoting better overall growth. Carefully select one-third of the old branches and prune them close to the ground. Aim to create an open and airy appearance while maintaining the natural shape of the shrub.

To encourage new growth and profuse flowering, you can also perform rejuvenation pruning on older, overgrown forsythia. This process involves cutting the entire shrub back to within a foot or two of the ground. Though drastic, it will stimulate new growth from the base of the plant, resulting in a more vigorous and attractive shrub. Rejuvenation pruning is typically done every 3-4 years for forsythia to keep it looking rejuvenated and healthy.

Remember to make your cuts at an angle, about one-fourth inch above an outward-facing bud or a junction with another branch. This angled cut allows rainwater to drain away from the bud and promotes proper healing. Avoid leaving stubs behind as they can attract diseases and pests.

It is important to note that forsythia has a natural growth habit, and excessive pruning might lead to stunted growth or a lack of flowers. Therefore, it is crucial not to overprune the shrub. Also, avoid pruning during the fall or winter months, as this could remove the flower buds for the following spring.

After pruning, apply a layer of organic mulch around the base of the shrub to help retain moisture and suppress weed growth. Water the plant thoroughly after pruning to aid in the recovery process.

In conclusion, pruning forsythia is necessary for maintaining its health and promoting abundant blooms. By following the tips provided in this article, you can ensure that your forsythia remains vibrant and visually appealing. Remember to prune after flowering, remove dead or damaged branches, thin out the plant, and consider rejuvenation pruning for older shrubs. Enjoy the beauty of golden bell shrubs in your garden year after year with proper pruning techniques.
