The Best Time to Prune

An important aspect of pruning is knowing when to prune trees, shrubs, & plants.  Proper timing helps to insure attractive, healthy & productive plants.  A good guideline time to prune various plants are indicated below:

Evergreen Shrubs

Prune evergreen shrubs, such as juniper and yew, in late March or early April before new growth begins.  Light pruning may also be done in mid-summer.  Avoid pruning evergreen shrubs in the fall.  Fall pruned evergreens are more susceptible to winter injury.

Deciduous Trees

February through March is generally regarded as the best time to prune most deciduous trees.  The absence of foliage at this time of year gives the individual a clear view of the tree and allows the selection and removal of appropriate branches. However, if possible, avoid pruning deciduous trees in spring when the trees are leafing out and in fall when the trees are dropping their leaves.  Also, the walling-off or compartmentalization of wounds occurs most rapidly just prior to the onset of growth in spring.  Oaks are an exception.  The winter months – December, January, and February – are the best time to prune oak trees.

To reduce the risk of an oak wilt infection, do not prune oaks from March through October.  Oak wilt is a fungal disease that is lethal to many oaks.  It can spread from infected trees to healthy trees by sap-feeding beetles (“picnic bugs”).  If an oak tree must be pruned in spring or summer (such as after a storm), apply latex housepaint to the pruning cuts to avoid attracting sap-feeding beetles to the wounds.


Evergreen Trees

Evergreen trees, such as pine, spruce, and fir, require little pruning.  Dead, broken, and diseased branches can be removed at any time of year.  Late winter is the best time to remove unwanted lower branches on evergreen trees.

Spruce and fir trees possess side or lateral buds on their newest (outermost) growth.  To promote denser growth, cut shoots back to just above a lateral bud or side branch in early spring.

Growth on pine trees develops from terminal buds.  Pines do not produce side or lateral buds.  The growth of pines can be slowed by pinching or pruning off one-half to two-thirds of the elongated terminal buds (“candles”) in spring when the candles are approximately 2 to 3 inches long.  Do not prune branches back to older growth down the stem as new growth will not develop from these areas.

Fruit Trees

Late February to early April is the best time to prune fruit trees.  Pruning should be completed before the fruit trees begin to break bud (leaf out) in early spring.

Deciduous Shrubs

The proper time to prune deciduous shrubs is determined by the plant’s growth habit, bloom time, and health or condition.

Spring-flowering shrubs, such as lilac and forsythia, bloom in spring on the growth of the previous season.  The plant’s health or condition determines the best time to prune spring-flowering shrubs.

Neglected, overgrown spring-flowering shrubs often require extensive pruning to rejuvenate or renew the plants.  The best time to rejuvenate large, overgrown shrubs is late winter or early spring (March or early April).  Heavy pruning in late winter or early spring will reduce or eliminate the flower display for 2 or 3 years.  However, rejuvenation pruning will restore the health of the shrubs.

The best time to prune healthy, well-maintained spring-flowering shrubs is immediately after flowering.  (Healthy, well-maintained shrubs should require only light to moderate pruning.)  Pruning immediately after flowering allows gardeners to enjoy the spring flower display and provides adequate time for the shrubs to initiate new flower buds for next season.

Summer-flowering shrubs, such as potentilla and Japanese spirea, bloom in summer on the current year’s growth.  Prune summer-flowering shrubs in late winter or early spring.  The pruned shrubs will bloom in summer on the current season’s growth.

Some deciduous shrubs don’t produce attractive flowers.  These shrubs may possess colorful bark, fruit, or foliage.  Prune these shrubs in late winter or early spring before growth begins.

Do not prune deciduous shrubs in late summer.  Pruning shrubs in August or early September may encourage a late flush of growth.  This new growth may not harden sufficiently before the arrival of cold weather and be susceptible to winter injury.

So the question on everyone’s mind is how much does it cost?

Pruning or Trimming

Pruning, also known as Trimming, costs can depend on several factors including type of tree, size of tree, amount & size of shrubs, amount of clean up, plus disposal labor & fees . Bigger trees typically take more time to navigate and have larger branches to work on.  Other factors can determine the price too such as: are there obstacles (such as fences, roofs, walls, & slope of terrain),to work around in order to keep those obstacles safe from falling limbs and our staff safe as well. The main factors to consider when factoring a cost are the size & amount of trees, shrubs & plants…the accessibility, terrain & size of property… as well as ease or difficulty of clean up & disposal.

Small trees start at around $95.00 for pruning, and around $150.00 for removal. Medium trees can vary depending on the above mentioned factors. Very large trees can cost as much as a $1,000.00 to prune and even more for removals depending largely on the size of the stump. Our smallest pruning or clean up package starts at $180 and can be as much as several thousand dollars.  However, on average the majority of properties we have worked on over the last 20 years came in at around $350 to $950.
