However, as an evergreen shrub, somephotinia red robin problems may be hard to handle. For one, they do not necessarily need pruning, as they grow into small yet perfectly formed shapes themselves. Yet, shaping some of the strays and protruding stems may be a good idea and protect the photinia red robin problems.

In this article, we guide you through the complete process of pruning Photinia Red Robins.

Why Prune Red Robins

Since Red Robins are naturally shrubbing plants, you might ask if pruning them is necessary. The answer is yes, and the first reason behind such an effort is to keep the plant safe. The Photinia x fraseri cultivars often get fungal diseases like leaf spots. And if you were to prune the insides during autumn or winter, you are sure to reduce its chance of spotting. 

Another reason why Red Robins are pruned is to bring out their beautiful foliage. The exciting colors and young leaves create an enchanting display through the hedges. This is usually achieved with spring trimming the stems. 

When to Prune Red Robins

As we know, Photinias are evergreen shrubs. But trimming them about twice a year helps their growth massively. For one, the spring trimming helps you attain the beautiful foliage of pink and red for which it is famous. However, if you were to leave the stems untouched, you would see the growth of little flowers.

The cluster of little cream flowers arrive on the stems around late spring and early summer. And they are a delightful sight against the young green leaves. But having them displayed proudly means you will not have colorful foliage. 

Materials and Preparation for Pruning Red Robins

There are a few things to keep in mind while pruning Photinias. They might be easy shrubs, but trimming them requires little planning. You would only need some gardening gloves and a pair of secateurs or pruning shears to start the shaping. 

But ensure you have sterilized the instrument carefully to avoid the leaf spots. Diluted rubbing alcohol or even hand sanitizers work fine on the shears. Avoid going out in the rain to start the pruning process. And make sure your shears are sharp enough to make clean cuts. 

Topping vs. Thinning

Broadly speaking, two types of pruning are done on photinia red robins. The first is topping, which is done to retain its natural shape. When photinias grow older, they may have some taller branches shooting up, which people just nip. However, this harms the plant’s health as it leaves them vulnerable.

The other kind of pruning is thinning, where the branches are cut off at the source of the plant. This is usually attempted as it ensures the plant’s safety while keeping it healthy and in shape. 

Autumn Pruning 

During the autumn pruning, the aim is to keep it from getting diseased leaves. So you have to thin out the lower and interior parts of the bush. If they have grown dense, they need to be opened up, especially if that specific shrub is prone to leaf spots. The health of the entire plant is improved with air circulation and light optimization from the pruning. 

However, going in doesn’t mean shearing through since the foliage needs to be kept pretty. Start from the bottom and cut away the stems that have dead leaves on them. By cutting away the older parts annually, you get a healthy and relatively effortless plant year-round. 

Spring Pruning

The timing of the spring trimming depends on your weather. Ensure all signs of frost have left the air so it will not hinder fresh growth. Photinia red robins are fast-growing plants, so you may need to prune 10-18 cm of new branches. This will help the fresh growth bloom and trigger the beautiful foliage to come forth. 

Not every stem and branch are to be sheared the same length. Taller and straggly branches need to be trimmed to great lengths to match the shorter ones. To make the flowers bloom, only prune about 50% of the new branches. With spring trimming, you can shape the bush into a gentle upward taper. 

Final Thoughts

Photinia red robins are a great plant to border your garden with. The beautiful foliage of red and pink often gives it the name of Christmas berry. They are also fast-growing and relatively easy to take care of. But these shrubs require pruning to be kept in their delightful display for years. 

Pruning red robins is necessary to keep the fungal diseases at bay. And if you were to prune twice a year, you would surely get foliage worth showing off. And annual trimming makes this job much easier as time goes by.
