In our previous blog, we highlighted how autumn lawn preparation sets the stage for a lush, vibrant lawn in spring. Now, we turn our attention to late-summer trees and shrub care – a critical component of landscape maintenance that ensures your greenery remains healthy and resilient through the colder months.
Early detection
The actions you take now are vital for ensuring that your trees and shrubs not only survive the winter but emerge healthier and more robust in the spring.
With decades of experience in commercial tree inspection and maintenance, which has earned us ARB Approved Contractor status awarded by the Arboricultural Association, we know that proper care during this period can make all the difference to their long-term health and vitality.
The intense heat and occasional storms of summer can take their toll on trees and shrubs, leading to issues like dehydration, nutrient deficiencies, or pest infestations.
Our Lantra-awarded tree inspector checks for these issues during inspections, along with other stress indicators like wilting leaves, bark cracks, or discoloured foliage. Early detection and treatment provide your trees with the best chance of recovery and long-term health.
Pruning for autumn preparation
Late summer is an ideal time to prune certain trees and shrubs, promoting healthy growth and preventing winter damage. However, it is important to select species that respond well to pruning at this time to minimise stress and avoid issues like sap bleeding or disease susceptibility. Below are some trees and shrubs that are generally recommended for late-summer pruning:
Trees:
- Flowering Dogwood (Cornus florida): Prune to shape and remove dead or diseased wood.
- Crabapple (Malus spp.): Pruning helps reduce the risk of disease and improves air circulation.
- Magnolia (Magnolia spp.): Prune after flowering to maintain shape.
- Cherry Laurel (Prunus laurocerasus): Benefits from light pruning to control size and shape.
Shrubs:
- Panicle Hydrangea (Hydrangea paniculata): Pruning can encourage healthy blooms the following year.
- Rose of Sharon (Hibiscus syriacus): Pruning helps maintain shape and promotes new growth.
- Boxwood (Buxus spp.): Responds well to light pruning to maintain shape.
- Spirea (Spiraea spp.): Pruning after the first bloom can encourage a second flush of flowers and maintain a neat shape.
These shrubs are well-suited to late-summer pruning because they typically enter a period of slower growth, reducing the risk of stimulating too much new growth that might not harden off before winter.
Pruning now also helps shape your plants and removes dead or diseased wood, giving trees time to heal before cold weather sets in. This preparation sets them up for success in the coming year.
Fertilisation and soil care
One of the most critical aspects of tree care that we always emphasise is soil health. Late summer is the perfect time to evaluate your soil and apply necessary fertilisers. A balanced approach to fertilisation – including the right mix of nitrogen, phosphorus, and potassium – is essential for supporting root development and ensuring your trees and shrubs are fortified against the winter.
Mulching is another key practice we advocate for. By applying a good layer of mulch – such as wood chips, bark, or compost – you can protect roots from temperature fluctuations, conserve soil moisture, and prevent weed growth. Simple steps like these make a significant difference to the overall health of your landscape.
In our commitment to both exceptional tree care and environmental stewardship, we also recommend incorporating sustainable practices into your landscape maintenance. Water conservation, through techniques like drip irrigation, not only reduces water usage but also minimises runoff, which helps protect local waterways and promotes a more sustainable landscape.
Irrigation adjustments
As we move away from the peak of summer’s heat, it is important to adjust your irrigation practices. From years of managing commercial landscapes, we have learned that while trees and shrubs may need less frequent watering, deep watering remains essential for strong root growth. Adjusting your irrigation system to water less often but more deeply ensures that moisture reaches the roots, helping your trees withstand drier winter conditions.
Pest and disease management
As stated earlier, late summer is a critical time for managing pests and diseases. Conducting a thorough inspection of your trees and shrubs now allows issues to be addressed before they become severe. Common pests like aphids, which cluster on leaves and stems, or spider mites, which thrive in hot, dry conditions, can cause considerable damage if not treated promptly.
Diseases such as powdery mildew, which coats leaves in a white, powdery substance, or black spot on roses, which leads to leaf drop, are also prevalent during this time and require immediate attention to prevent widespread harm.
Identifying these issues early allows you to apply targeted treatments – like insecticidal soaps for aphids, miticides for spider mites, or fungicides for powdery mildew and black spot – keeping your plants healthy.
With our extensive knowledge in arboriculture, we can recommend the most effective treatments and preventative measures tailored to your landscape’s specific needs.
This proactive approach not only protects your trees and shrubs from late summer threats but also strengthens them, ensuring they are healthy and robust as they enter the winter months.
Planning for autumn planting
Planning for autumn planting is another area where our expertise comes into play. Autumn is often the best time to establish new trees and shrubs, as the cooler temperatures and consistent rainfall create ideal conditions for root development. Species like dogwoods (Cornus spp.), Japanese maples (Acer palmatum), or viburnums (Viburnum spp.) are excellent choices for this season. Planting these in autumn allows them to establish strong root systems in cooler, moist conditions, preparing them for vibrant growth and flowering in the spring while minimising stress and exposure to pests.
Additionally, if you are looking to support local ecosystems and reduce maintenance, consider planting native UK species. Trees like the English oak (Quercus robur), silver birch (Betula pendula), and shrubs like the common hawthorn (Crataegus monogyna) or the Guelder rose (Viburnum opulus) are excellent autumn choices. These native plants are well-adapted to the local climate, more resilient to local pests and diseases, and contribute to a sustainable, low-maintenance landscape. Our planting expert can guide you in selecting the right plants and ensure they are properly planted for long-term success.
