How to Prune Buddleja

There is no denying the fact that pruning your plant is quite necessary to eliminate the damaged parts and keep your plant healthy. However, knowing how to correctly trim your plant without affecting its look and quality is equally important.

Before moving any further, we would like to list some important tools that you must have before pruning your Buddleia plant. Some of these items include:

• Appropriate pruning shears
• Gloves
• Shovels and more.

Now you may follow the below-mentioned steps to trim your plant correctly.

1. Knowing when to prune Buddleia is the most significant factor when considering the plant’s trimming. However, the right time depends on the climate of the area where you’re residing; the obvious rule states that the plant needs trimming around the spring.
2. Also, there are some varieties of Buddleia which blossom on the previous year’s branches. This implies that if you decide to trim such branches in spring, you will lose new flower buds. And that is why for varieties like Globasa, it is suggested to prune them around summer.
3. Pruning the Globasa varieties needs the trimming of branches at a 45-degree angle. You should also be careful to leave some buds on the branches to encourage flowering.
4. Additionally, for other general varieties, you may trim the branches at a 45-degree angle around the spring season only. Moreover, ensure that the height of the plant remains at least 30 cm even after cutting.
5. The overcrowding of Buddleja’s branches can affect its growth and flowering, which is why it is suggested to eliminate the excess or old branches.
6. The best way to identify a rotten or old branch is to look at its colour. The old branches are generally of greyish or brown shades.
7. Pruning the dying blooms of your Buddleja plant at regular intervals is quite important to promote healthy growth while also keeping it tidy at the same time.

When to Prune Buddleja

The Buddleia plant is often noted for its fast growth and is sometimes referred to as an invasive species. The absence of pruning won’t just make the plant grow at a rapid rate but also hamper its appearance. Its branches can get all tangled, and the whole look can seem untidy, making it important to trim them adequately.

The majority of Buddleia varieties flower in summer, making spring the most suitable time to trim your plant. However, if there is any unwanted change in the weather, like frost or freezing temperatures, it is suggested to push back your pruning plans for a while.

So, when the weather is favourable, correctly trim the damaged and old branches to promote lovely blooms in the new season.

Buddleia and the Need for Pruning

Buddleia, or what is commonly known as “Butterfly Bush”, were originally grown in China, but the mesmerising beauty of the plant gained worldwide attention. The plant was introduced in the UK in around the 1890s and has been quite popular for appealing to butterflies of different varieties, thus the name Butterfly Bush.

The plant comes with narrow leaves and beautiful flowers in shades of purple and sometimes white that can enhance the beauty of any garden.

Like any other plant, Buddleia also requires some kind of attention and care to maintain its health. Pruning is one of the most requirements in that aspect. The need for pruning for Buddleia can be understood in these ways:

• Pruning helps remove unwanted parts and thus makes your plant more appealing and attractive.
• It is necessary to remove damaged parts so that they don’t spread further and harm your Buddleia.
• Cutting back your Buddleia restricts its growth to the levels you want. Otherwise, it can grow quite rapidly.
• Trimming is also important to improve growth.

Caring Tips for Buddleia

Generally, the plant doesn’t require any specific fertilizing and more as it sufficiently grows on its own.

Also, adding too much fertilizer can make the leaves grow too fast and not flowers.

4. Compost

You may use a suitable kind of compost for your plant after pruning. This will not only enhance their healthy growth by keeping the moisture intact, but it also helps kill weeds and other unwanted insects and more.

The brown marks on the leaves are also signs of fungal contact and cause withering of your Buddleia.
