Pruning the Lewis mock orange, also known as Philadelphus Lewisii, is an important step in maintaining its shape and size while promoting healthy growth and abundant flowering. The best time to prune this shrub is soon after it has finished blooming, which is typically in the spring. By pruning at this time, you will allow the plant enough time to produce new growth and set buds for the following year’s flowers.
When pruning the Lewis mock orange, it is recommended to top prune the plant to improve its overall shape and reduce its size if necessary. This can be done by selectively cutting back the branches to the desired height or length. However, it is essential to be cautious and not remove more than 30% of the top growth, as excessive pruning can stress the plant and affect its ability to recover.
To begin, assess the overall shape of the shrub and identify any branches that are crossing, damaged, or growing in an undesirable direction. Start by removing these branches, making clean cuts just above a healthy bud or lateral branch. This will help maintain the plant’s natural form and prevent overcrowding.
If the Lewis mock orange is particularly vigorous or has become overgrown, some additional summer pruning can be done. However, it is crucial to avoid pruning after mid-July, as this can interfere with the plant’s ability to set buds for the following year’s flowers. Summer pruning can involve selectively removing a portion of the new growth to reduce the shrub’s size and encourage branching.
When pruning, it is important to use sharp and clean pruning tools to make precise cuts. Dull or dirty tools can damage the plant and potentially introduce diseases. Before pruning, sterilize your tools with rubbing alcohol or a mixture of bleach and water to minimize the risk of spreading pathogens.
After pruning, it is beneficial to apply a layer of mulch around the base of the shrub to help conserve moisture and suppress weed growth. This will also provide some insulation to the plant’s roots during extreme temperatures.
Pruning the Lewis mock orange should be done soon after it has finished blooming, typically in the spring. Top pruning can improve the plant’s shape and reduce its size, but it is important not to remove more than 30% of the top growth. Summer pruning can be done on particularly vigorous plants, but should not be performed after mid-July to avoid interfering with bud formation. Use sharp and clean pruning tools, and apply mulch after pruning to promote healthy growth and conserve moisture.
