Spring
Spring is a beautiful season that signals the return of life and vibrancy to our surroundings. It is a time of new beginnings and rejuvenation, and the perfect time to tend to our gardens and landscapes. Let’s explore the different stages of spring and the best practices for each.
Early Spring
Early spring is when the Earth begins to awaken from its winter slumber. The weather starts to warm up, and the first signs of growth become evident. This is the ideal time to prune certain plants before they start their active growth. Fruit trees, such as apple, peach, cherry, and plum trees, should be pruned during this time. Pruning stimulates new growth and improves the overall structure and health of the trees.
Flowering shrubs like roses, hydrangeas, lilacs, and forsythia also benefit from a gentle pruning in early spring. Removing dead or damaged branches and shaping the shrubs will enhance their appearance, encourage blooming, and promote healthy growth.
Mid-Spring
As mid-spring arrives, plants are in full swing, bursting with energy and showcasing their vibrant colors. This is a crucial time for maintaining the health and beauty of your landscape. Focus on pruning evergreen trees like pine, spruce, cypress, and fir during this period. Trimming back any diseased or overgrown branches will prevent the spread of diseases and ensure the trees’ longevity.
Deciduous trees, such as maples, oaks, birches, and willows, also benefit from mid-spring pruning. Remove any crossed or rubbing branches and thin out dense areas to increase air circulation and sunlight penetration. This will prevent the trees from becoming overcrowded and reduce the risk of diseases.
Late Spring
Late spring is a time of splendor when gardens are in full bloom, and nature is at its most vibrant. It is recommended to refrain from heavy pruning during this period as many plants are actively flowering. However, you can still remove spent blooms from flowering shrubs like roses to encourage prolonged flowering. Regular deadheading will keep your garden looking fresh and neat throughout the season.
Late spring is also an excellent time to shape hedges. Boxwood hedges, privet hedges, yew hedges, and arborvitae hedges can be lightly pruned to maintain their desired size and form. Avoid drastic pruning that may leave the plants vulnerable to stress or damage.
Summer
Welcome to summer, the season of sunshine, warmth, and the peak of outdoor enjoyment. While pruning activities generally decrease during this season, there are still a few plants that require attention. Let’s explore the different stages of summer and the pruning tasks that accompany each.
Early Summer
Early summer brings with it lush greenery, blooming flowers, and a burst of energy from the natural world. This is the ideal time to focus on pruning fruit trees that bear their fruit later in the season, such as peaches and plums. Thin out excessive growth to ensure good air circulation and facilitate sunlight penetration, which will promote fruit development and reduce the risk of diseases.
Flowering shrubs, such as hydrangeas, may also require some early summer maintenance. Prune hydrangeas that bloom on old wood soon after they finish flowering. Remove any dead or weak stems and shape the shrub to maintain its form and size.
Mid-Summer
Mid-summer is characterized by longer days, higher temperatures, and thriving gardens. It is advisable to limit pruning activities during this period as many plants are actively growing and blooming. However, it is essential to remove any dead, diseased, or damaged branches from trees and shrubs to prevent the spread of pests and diseases.
Evergreen trees like pine, spruce, cypress, and fir can be lightly pruned in mid-summer to remove any dead or discolored needles. This will promote healthier growth and maintain the trees’ aesthetics. When pruning, be cautious not to remove more than 20% of the tree’s foliage, as excessive pruning can weaken the trees.
Late Summer
Late summer is a time of transition as the days begin to shorten, and the weather starts to cool. While pruning activities are minimal during this season, it is an excellent time to prepare for the upcoming fall. Start by removing any dead or dying flowers from flowering shrubs like roses to encourage a second wave of blooms. Light pruning can also be done to shape the shrub and remove any unruly branches.
Maintaining ornamental grasses becomes essential in late summer. Cut back ornamental grasses like pampas grass, fountain grass, maiden grass, and feather reed grass to approximately six inches from the ground. This will encourage fresh growth and help the grasses maintain their attractive form.
Fall
Fall is a season of transformation, when the world around us is painted in hues of gold, red, and orange. It is a time of preparation for the upcoming winter and an opportunity to care for our plants. Let’s delve into the different stages of fall and the pruning tasks associated with each.
Early Fall
Early fall brings with it cooler temperatures and a sense of change in the air. This is the perfect time to prune deciduous trees like maples, oaks, birches, and willows. Remove any dead, damaged, or weak branches, and thin out crowded areas to enhance the trees’ shape and structure. Pruning during this period also reduces the risk of falling branches during winter storms.
Late-blooming perennials and flowering shrubs can also be pruned in early fall. Cut back the spent flower stalks and remove any dead or diseased foliage to prevent the spread of diseases and pests. Be cautious not to remove too much foliage, as some plants rely on their leaves to store energy for the winter.
Mid-Fall
Mid-fall is when the beauty of autumn reaches its peak, and the world around us is awash in golden hues. Pruning activities during this time are generally limited in order to allow plants to transition naturally into dormancy. However, it is advisable to remove any leaves, branches, or debris that may have fallen onto lawns, flowerbeds, or walkways to maintain a tidy appearance.
Hedges, such as boxwood, privet, yew, and arborvitae, can be lightly pruned during mid-fall. Trim any unruly growth and shape the hedges to maintain their desired form. Light pruning also encourages denser growth and prepares the hedges for the oncoming winter.
Late Fall
Late fall marks the end of the growing season, as nature prepares for the long winter ahead. This is a good time to complete any remaining pruning tasks before the onset of freezing temperatures. Take advantage of the dormant stage of fruit trees to prune them back, removing any dead, diseased, or crossing branches. Slightly thinning out the canopy will also allow more sunlight to reach the inner branches, promoting healthier growth and fruit production in the following year.
Late fall is also an excellent time to shape and prune evergreen trees like pine, spruce, cypress, and fir. Remove any dead or diseased branches and thin out dense areas to improve airflow and reduce the risk of snow damage during the winter months.
Winter
Winter, a season often associated with dormancy and stillness, provides an opportunity for reflection and planning for the year ahead. While pruning tasks are generally limited during this season, there are still a few plants that benefit from winter pruning. Let’s explore the different stages of winter and the pruning tasks associated with each.
Early Winter
Early winter is a time when nature seems to hold its breath, waiting for the first signs of spring. Pruning activities during this period are best reserved for dormant fruit trees like apple, peach, cherry, and plum. Pruning in early winter helps shape the trees and remove any diseased or dead branches before the onset of new growth. Be mindful not to remove more than 25% of the tree’s total branches to avoid stressing the tree.
Evergreen trees like pine, spruce, cypress, and fir can also be pruned in early winter. Remove any broken branches, dead foliage, or weak growth to maintain their health and aesthetics. It is important to note that excessive pruning of evergreen trees during winter should be avoided, as it may cause stress and damage, particularly in colder climates.
Mid-Winter
Mid-winter is when the world is often covered in a blanket of serene white snow, and the garden is in deep slumber. Pruning activities during this time are minimal, as most plants are in their dormant phase. However, it is a great time to inspect trees and shrubs for any signs of disease or damage that may need immediate attention. Pruning infected or diseased branches during mid-winter can help prevent the spread of pathogens and maintain the overall health of your landscape.
Late Winter
Late winter is the prelude to spring, when the days gradually become longer, and the promise of new life fills the air. While pruning activities are generally limited during this period, it is a good time to prepare for the upcoming growing season. Shape and prune evergreen trees before new growth begins, removing any dead or damaged branches to encourage healthy growth in the coming months.
As the winter frost starts to recede, it is advisable to remove any dead or rotted wood from fruit trees in late winter. This preventive measure helps maintain the trees’ health and reduces the risk of diseases in the upcoming growing season.
