Pruning a Forsythia: 6 Trimming Techniques

Several approaches could be used by the gardener to mow the forsythia flower. This could be in reverence to the gardener’s choice or the age of the forsythia.

Approach 1

Eliminate a quarter of the oldest stems by cutting at the ground level. Through the period of growth, the stems of the forsythia become thicker. This causes friction between them inside the shrub. This friction can reduce plant health strength.

To prevent this, remove the old thick stems with a handsaw. It is advised to remove this old stems quickly to avoid injuries.

Usually, the old stems are always the tallest in the forsythia. Their removal will reduce the consequent height of the forsythia shrub. There is a possibility of the gardener, not being able to access the bottom of the shrub. There is an improvisation of cutting the stems from about 3-4 in from the ground level.

It is imperative to note that this type of pruning is advisable when the plants are about 5-6 years old. At this stage, they are matured enough to survive this pruning approach.

Approach 2

This is a more modest approach to the mowing of forsythia. It involves the cutting of old stems at about 12 in away from the bottom of the stem. Through this, growth is quick, and the forsythia takes shape in no time. Rather than cutting the stems at the ground, about a foot (1ft) is left to spur re-growth.

With this cutting method, new stems grow from the remaining part of the stem. It helps to reduce plant altitude while promoting the growth of new shoots.

Approach 3

In some cases, the forsythia shrub grows branches towards its base. This disfigures the shape of the beautiful forsythia shrub. This approach removes the branches low to the ground to maintain plant configuration.

To reshape the forsythia plant, simply terminate these branches with a pruning shear. It is essential to cut at the point the branch sprouts off the other stem.

The failure to remove these low trunks can lead to them being rooted to the ground. This would ruin the overall structure of the forsythia tree as an ornament.

Approach 4

As perennials grow, they shed a few dead branches. This mowing technique involves the discontinuation of bent and split stems to ensure plant shape is maintained. Also, dense stems in some plants may reduce plant attractiveness. It is necessary to stop the inside growth of the branches through pruning.

This strategy also advocates the removal of dead branches within or at the base of the forsythia.

Approach 5

Forsythia branches form a canopy. In this approach, branches are cut to the point of origin to thin out the shrub canopy. Utilize pruning shears or loppers to discontinue any surplus branch towards the top of the forsythia.

Through this, the exquisite shape of the shrub is maintained. The majority of stems are also removed. Do this for branches that point upwards, stem parts that cross, root extension that rubs against other branches.

All the tall branches are cut to give the forsythia a standard height. More so, this enables light to penetrate the center of the shrub. This spurs the healthy growth of the forsythia.

Approach 6

Crop the stems to about 5in height, if they are abruptly taller than average. This is a massive pruning method, and it is only advised when the plant is starting to take over the garden bed. All items are cut to the ground. This leaves room for new shoots to grow from the cut stems.

After cutting, remove the branches to keep the plant open and spaced.

This approach is required to be done during the last days of winter to attain the best possible results. It takes a few years, for the plant to look full again

Notably, younger forsythia shrubs are more comfortable to keep in shape with constant care. The older Forsythia shrubs require a brutal pruning process to stay in shape. This is due to their root strength and branch outlets.

Therefore, for any forsythia, pruning during all springs will reward you with a well-shaped shrub at all times.

The Pruning Position

You approach the overgrown forsythia on hands and knees. This allows to trim off the canes lying on the ground, thus forcing the shrub to flow upward. The canes are identified by the lack of small branches growing out of them.

The knee position also enables the gardener to access the bottom section of the stems easily. Also, in cases of stem trimming, it becomes easy to identify the perfect position the gardener would love to cut from.

When To Prune Forsythia

In life, timing is everything. The timing of your forsythia shrub snipping depends on what you are trying to achieve.

Nonetheless, the early spring days are the most advisable time to prune. Usually, forsythia new flowers bloom on stems that formed the blossom buds the previous year. If you prune before these stalks produce flowers, you might not have flowers that year.

In cases where the gardener crops regularly. The forsythia is expected to be in good shape. The gardener can go ahead to snip after proper flowering. Consequently, in most cases, there is a lack of consistency in cropping. This requires more work in trimming, so it best to cut before it flowers.

For regeneration trimming or overall shrub size reduction, it is best to prune in the late winter or early spring when the forsythia is partially inactive. This may lead to a reduction in the expected bloom.

Nevertheless, the perfect structure the plant maintains through springtime is a decent reward.

Tools for Effective Forsythia Pruning

The role the right gears play in guaranteeing effective pruning of forsythia cannot be overemphasized. Quality snipers not only make the trimming easier. They also result in cleaner cutting that will heal quicker and result in a more elegant plant.

They are typically useful for harvesting forsythia trimmings and thrusting indoors. Bypass pruners also come handy in creating floral arrangements.

It is not advised to use bypass pruners to cut out dead branches, and there are special tools for this purpose.

Bypass Loppers

Bypass loppers are designed for trimming and snipping branches. They are also designed with a circumvent blade and long handles which enables them to access the center of these trees with ease.

Bypass loppers are capable of cutting stems and shoots in forsythia shrub. These handles ensure that the gardener does not get injured through the snipping process.

Pruning Saw

Great for slicing through large diameter stems and branches. The blade of the saw is well capable of reaching into shrubs and other enclosed stems. It is utilized in extreme cases of forsythia trimming. It is not recommended to be used for young forsythia shrubs, as it can cut off the stems.

Through the pruning process, it is essential not to get ahead of oneself. It is advised to take some steps backward periodically. This gives the gardener a perfect view of the forsythia shrub current state and the necessary parts that still require trimming.
