Pruning A Wedding Cake Tree: Tips And Techniques For Success

The Wedding Cake Tree, also known as the Cornus controversa, is a layered tree with branches that resemble the tiers of a wedding cake. It is slow-growing and requires minimal pruning. While it generally does not respond well to hard pruning, removing new shoots that could disrupt its outline is recommended. Pruning should be carried out from autumn to early spring, avoiding the spring to prevent insects from entering the wood and causing disease.

Pruning is best done in autumn or early spring

The Wedding Cake Tree is best pruned from autumn through to early spring. Pruning during these seasons helps to maintain the tree's shape and encourage healthy growth. Autumn and early spring are ideal for pruning as the tree is in a state of dormancy, making it less susceptible to stress. Pruning at this time also reduces the risk of pest and disease problems.

When pruning your Wedding Cake Tree, it is important to use sharp and clean tools to make precise cuts and avoid causing damage to the tree. It is also crucial to make proper cuts that promote healing and prevent issues such as rot or disease. Remove any dead, diseased, or damaged branches to improve the tree's overall health and appearance.

Additionally, it is essential to be mindful of the tree's growth pattern and natural shape. The Wedding Cake Tree is known for its distinctive tiered structure, and pruning should enhance rather than distort this unique feature. Pruning should focus on removing any stray branches that disrupt the overall shape and reducing the length of select branches to maintain the desired height and width.

By pruning in autumn or early spring, you can effectively maintain the Wedding Cake Tree's form and encourage its continued healthy growth.

Avoid hard pruning

The Wedding Cake Tree, or Cornus controversa 'Variegata', is a slow-growing tree that requires minimal pruning. While it can take some hard pruning, it generally does not respond well to it. So, if you want to avoid hard pruning, simply remove any new shoots that may disrupt the outline before they become established. This can be done from autumn through to early spring.

The Wedding Cake Tree will naturally form a crown of iconic 'wedding cake' tiers, so there is no need to prune it to achieve this shape. If you are training the tree as a standard, remove the low laterals over a number of years, leaving no more than a quarter as a clear stem.

If you want to maintain the shape of the tree, you can trim a couple of feet off some of the branches. This will also allow more light into the border. However, be careful not to prune too much, as this can affect the tree's appearance.

Overall, the Wedding Cake Tree requires little to no care beyond initial training. So, if you want to avoid hard pruning, just focus on removing any new shoots that may disrupt the tree's natural shape.

Remove dead or diseased branches

The Wedding Cake Tree, or Cornus Controversa Variegata, is a beautiful, ornamental addition to any garden. It is slow-growing and known for its distinct tiers of branches, which resemble a wedding cake. While this tree requires minimal pruning, it is important to remove dead or diseased branches to maintain its health and aesthetic appeal. Here are some detailed instructions for this process:

Identifying Dead or Diseased Branches:

Before pruning, it is crucial to accurately identify dead or diseased branches. A simple method is to snap a twig from the end of the branch and observe its inner parts. A live branch will be hard to snap and will have stretchy or fibrous qualities, with greenish, succulent inner tissue. In contrast, a dead branch will easily snap and display dry, brownish tissue inside.

Tools and Techniques for Pruning:

When removing dead or diseased branches, it is recommended to use pruning shears, loppers, or a special pruning saw. Ensure that your tools are clean and sharp to avoid causing further damage to the tree. Cut the branches at a 45-degree angle, close to the trunk, without leaving any stubs. Stubs can serve as entry points for insects and promote the spread of disease. Cutting at the correct angle also facilitates faster healing and reduces the chances of decay.

Safety Considerations:

Safety should be a top priority when pruning. Always wear protective gear, such as gloves, goggles, and a hard hat. Avoid pruning while standing on unstable surfaces, such as ladders. Dead branches can snap with considerable force, so be cautious of their direction when removing them. If you are unsure about the task, consider hiring a professional arborist.

Benefits of Removing Dead or Diseased Branches:

By eliminating dead or diseased branches, you promote the overall health of the Wedding Cake Tree. Dead branches can hinder proper healing, provide entry points for pests, and allow diseases to spread. Removing these branches redirects the tree's nutrients to healthier parts, making it more robust and vibrant. Additionally, dead branches can become a safety hazard during storms, as they are more likely to snap and fall.

Timing of Pruning:

The Wedding Cake Tree generally requires minimal pruning to develop its iconic tiered shape. However, if you need to remove dead or diseased branches, the best time to prune is during autumn or early spring. Avoid excessive pruning, as the tree typically responds poorly to it.

Avoid planting in chalky or alkaline soil

The Wedding Cake Tree, or Cornus controversa Variegata, is a slow-growing tree that requires minimal pruning. While it is possible to prune this tree, it is generally advised against as it does not respond well to hard pruning.

Now, here is some information on why you should avoid planting in chalky or alkaline soil:

Chalky and alkaline soils are usually fertile but present challenges for gardening due to their high alkalinity. This high alkalinity makes it difficult for plants to absorb necessary nutrients like iron, manganese, and other minerals, leading to poor growth and chlorosis (yellowing of leaves). These types of soil are commonly found in Britain and are often free-draining, able to hold water but only in small amounts, and prone to drying out.

Chalky soils specifically have a layer of chalk or limestone bedrock beneath the surface. They can differ based on their topsoil composition, with some having light and peaty topsoil, while others contain a significant amount of gravel or clay. The presence of clay particles can be beneficial as they help counteract the free-draining and poor water retention properties of chalky soil by holding onto water and nutrients.

Alkaline soils, on the other hand, are typically rich in chalk or limestone and have a high pH, usually between 7.1 and 10. They are often found in areas with chalk downlands or limestone deposits.

When planting in chalky or alkaline soils, it is essential to select plants that can tolerate these conditions. Some plants to consider include ornamental clovers like Trifolium rubens and Trifolium ochroleucon, wild marjoram or oregano (Origanum vulgare), lavender, rosemary, thyme, and artemisia. These plants will not only tolerate the high alkalinity but also the well-drained and free-draining nature of these soils.

Additionally, it is crucial to regularly amend chalky or alkaline soils with organic matter to improve their structure and fertility. This can include composted pine needles, leaf mould, manure, humus, compost, and/or peat moss. Regular fertilisation is also recommended to provide extra nutrients to the plants.

Plant in a sheltered spot to protect the tree's shape

The Wedding Cake Tree, or Cornus controversa 'Variegata', is a slow-growing tree known for its distinctive tiered appearance. It is important to plant it in a sheltered spot to protect its unique shape.

The Wedding Cake Tree is a statement piece and a living work of art that can grow to a height of 8-10 metres with a diameter of 5-6 metres. It is a tree with very layered growth, and its branches grow in layers, giving it a tiered appearance. This tree is native to Asia (China, Japan, Taiwan, and Korea) and can reach a height of 8 metres with a similar spread. It is a deciduous perennial tree with variegated foliage on the tiered branches from spring to autumn, flowers in summer, and colourful fruit in autumn.

To protect the tree's shape, it is best to plant it in a relatively sheltered spot, as wind can distort the tiered growth. If planted in an exposed site, the wind can effectively 'prune' the windward side of the tree, reducing its growth and giving it a lopsided appearance. This damage is difficult to rectify once it has occurred. Therefore, it is crucial to select a sheltered location when planting the Wedding Cake Tree to maintain its signature layered form.

The Wedding Cake Tree is best grown in a sunny spot or partial shade, on well-drained, fertile soil. It is happy in most soils but prefers to avoid chalk soil or alkaline conditions. It requires minimal pruning and does not respond well to hard pruning.
