ADEQUATE WATER FOR TREES AND SHRUBS
Trees and shrubs require more water during hot summer months. It’s a good time to consider investing in an irrigation system. If you already have an irrigation system, Tree Artisans recommends that you check the soil at the end of an irrigation cycle. If the soil is dry, extend the watering time for that zone.
Proper and adequate mulch helps conserve soil moisture and irrigation water. If you don't have an irrigation system, apply water through soaker hoses. Allow water to penetrate the upper 8" to 10" (20 to 25 cm) of soil. For most established woody plants, thorough irrigation once each week is adequate. For shallow-rooted plants and newly planted trees and shrubs, water should be applied two or three times per week – depending on weather conditions. If you are going on vacation, make provisions for watering while you are away.

EARLY FALL COLOR AND PREMATURE LEAF DROP
It’s nearly impossible to identify problems with your trees or shrubs without the help of a certified arborist. However, there are some things you should look for that can indicate a serious problem. During the summer, trees under stress frequently develop autumn coloration early and cast their leaves prematurely. This condition is often associated with serious root and soil disorders. If addressed early, soil or root management treatments like fertilization, proper irrigation, and root invigoration can give remedy for any issues. Premature autumn color and leaf drop could also be caused by vascular diseases or certain boring insects. An arborist can inspect trees to determine the underlying cause of this symptom and recommend appropriate action.
WARNING SIGNS OF TREE STRESS
As summer ends, look for any changes in your trees. Trees under stress display symptoms indicating that a serious problem may exist or could develop:
- Wilting or unusual loss of leaves or needles
- Yellowing of leaves or browning of needles
- Premature autumn color and leaf drop
- Wet, sappy spots on branches and stems
In some cases, your trees may simply need more – or less – water. However, these signs could be evidence of insects and diseases or problems with the roots or soil. Correctly identifying the underlying cause is critical to addressing the problem and nurturing trees back to health. A yearly checkup is a good idea to identify any early warning signs and keep your trees healthy.
One of the greatest dangers during storm season is falling trees and limbs. High winds and saturated soil conditions typically associated with summer storms can lead to tree root failure and weakened branches. While it is impossible to totally protect your trees and property from gale-force winds, there are some procedures that can reduce the risk of damage.
Have a certified arborist inspect your property for:
- Dead, dying, and weakly attached branches and dead trees
- Decayed or split stems and branches
- Root disease or disturbances
- Exceptionally dense canopies
- Trees with poor architecture
- Species with weak wood
Our arborists don’t use climbing spikes when performing maintenance procedures as they create wounds in stems that can lead to insect and disease infestations.
SCALE INSECT MANAGEMENT
Scale insects are parasites that plague evergreen and deciduous plants. They may be found on leaves, twigs, branches, or trunks. These pests feed on sap drawn directly from the plant’s vascular system. They may be controlled with horticultural spray oils, biological control, or pest-resistant plants. Preventive maintenance is the most cost-effective way to keep trees and shrubs free from infestations. It is important to have an arborist inspect your property and recommend appropriate action.
INVASIVE PLANT MANAGEMENT
Knotweed, honeysuckle, kudzu, and ivy are some of the most invasive species of plants. Proliferation of an invasive species can impact the natural balance of an ecosystem by overtaking and replacing indigenous plants and leaving animals and birds without forage for their normal diets.
If you have invasive plants on your property, summer is the time to treat them to prevent their spread. Systemic herbicide treatments applied to stems or foliage during the late summer and early fall can provide effective control. Treated brush can be removed in winter and desirable species planted in spring to provide a more sustainable environment.
