3. Pruning Euonymus shrub
As there are many varieties of euonymus, including deciduous and evergreen shrubs, it becomes difficult to adequately cover each variety. Therefore, we will begin by analyzing the aspects of pruning in a general way and then we will analyze the pruning of the four most popular varideades.
- Cleaning pruning
- Pruning to shape
- Hard pruning
We will analyze each of the previous prunings separately.
3.1 Cleaning pruning
Like any plant, the Euonymus, needs cleaning pruning, this will help keep the bush healthier. Step to enumerate which are the branches that must be eliminated when cleaning the pruning.
- Branches that are dead, dry, broken or diseased.
- Dry stumps (pieces of branches that have no shoots and are dead).
- Foot rebrotes that are weak or poorly located and we are not interested in their development.
- Branches crossed, poorly oriented or very tangled.
- Branches that protrude a lot from the bush because of its excess vigor.
It is advisable not to miss many years to perform this pruning. Otherwise entanglement will appear, the aesthetics of the plant will not be good, and the pruning at the time of doing it will be too strong.
On the other hand, be very careful when disposing of this pruning waste, especially if it is sick or attacked by a pest. Never leave this waste near other plants, since it will be spreading the disease or pest throughout your garden.
3.2 Pruning to shape
In general, Euonymus shrubs naturally develop a beautiful form, but often due to carelessness or by nature itself, they begin to take an elongated and unattractive form. To solve this, they can perform a pruning to form it.
If it is the first of these prunings that will give it, it is advisable to start densifying the foliage, something that is achieved by blunt all its branches. This will force the bush to release new shoots, if it does a couple of times, it achieves a good foliage density.
In case you have already formed the bush with pruning on other occasions, it is always good to recover it. Just look for the cuts of the previous pruning and cut the branches to that level, thus achieving the previous shape.
3.3 Hard pruning
In general, the Euonymus needs a hard pruning when it begins to see that its foliage is more scarce and not covering the spaces it covered in previous seasons. Its branches are too woody and its shoots grow with less force.
If that is the case with your Euonymus, do not be afraid to perform hard pruning. I waited until all the frosts of the year have passed and then cut all the branches about 20 cm from the ground (this may vary depending on the variety of Euonymus).
During the spring you will see how the bush begins to release new and strong shoots from its base. They will be in charge of forming their structure in the following seasons.
This hard pruning may also be necessary when the bush has been attacked by a pest that we can no longer control.
4. Euonymus pruning according to its variety
Here we will briefly analyze the particularities found in the pruning of four of the most popular varieties of Euonymus. They are; Golden Euonymus, Euonymus alatus, Euonymus japonicus and Euonymus fortunei.
3.1 Pruning golden euonymus
Evergreen shrub with large, bright, oval-shaped leaves that are dark forest green and broadly edged in bright golden yellow. Fast growing: good to use as a colorful hedge or as a bright accent plant.
The golden euonymus should be pruned in spring, just after flowering. This is the right time for both maintenance pruning, or pruning to shape. It is also a good time if you need to perform hard pruning. Never do an early pruning in winter, since you will be losing all or much of the floral production.
3.2 Pruning Euonymus alatus
This is a deciduous shrub whose size can reach up to three meters high. Its completely smooth and gray-colored bark with its young green branches give a touch of beauty to any garden.
This shrub due to its deciduous characteristics can be renewed with hard prunings quite regularly. They must be carried out at the end of spring. You can also perform maintenance prunings, lighter, in the last days of winter.
3.3 How to prune Euonymus japonicus
It is an evergreen shrub that can reach 3 or 4 meters high. Its leaves are bright green with yellow or white stripes. They produce red fruits that give Euonymus japonicus a distinctive touch. In general, they are widely used to grow in large pots or planted in isolation in the garden.
As I mentioned with the pruning of the golden Euonymus in this case, you should also wait to perform the pruning once the flowering is finished. This for light and hard pruning.
3.4 How to prune Euonymus fortunei
Finally, Euonymus fortunei is an evergreen shrub that stretches across the ground when it adopts a creeping habit or can also climb ivy-shaped walls through aerial roots. In general it has a fairly low size (1 meter high) with beautiful green leaves with cream-colored edges.
It admits to prune perfectly and lends itself to give them varied forms. The right time to prune is between April or May. To know which branch to cut and which not to cut, we suggest that you take a look at the color of the foliage every year or so to identify any which has lost its variegated markings. Prune the affected foliage away to retain the variegated areas.
4. When to prune Euonymus
There are many factors that affect the appropriate moment in which the pruning of the Euonymus should be carried out, among the most important is the variety, the type of pruning and the climate.
If you have been careful to read the previous sections, we have made it clear for each case what is the best time to prune.
Here I want to emphasize that in those varieties that bloom in wood of the previous year they should always be pruned once the flowering ends. Otherwise, and as we have clarified above, I would be losing the flowering.
