Urgent Reminder: Water Trees Planted Within the Last 3 Years!
| |
| A Youth Conservation Crew member waters a tree at Lee Elementary School, and volunteers on the Roseway Park Blocks care for their new trees.
| |
| Planting a tree is a great first step toward receiving years of benefits, but watering your tree for two to three years is critical to its survival.
| |
|
Newly planted trees need your help to survive. The immature root system is not able to access water beyond its limited space, and without your establishment care, it will wither away and die in our sunny Oregon summers.
| |
| A young tree shows classic signs of distress- brown leaves, and leaf loss.
| |
| At least two years, preferably three, of supplemental watering will help to establish your tree for many years to come. Ask a tree professional or the nursery where you purchased your tree about specific watering needs. In the meantime, check out the guide below for general tips on caring for young trees.
| |
|
It's important that the water directly reaches the root ball of your tree, close to the trunk, usually within 1 to 2 feet.
| |
|
Approximately 10 gallons of water per diameter inch of tree trunk (i.e., a 1.5 inch trunk requires about 15 gallons).
| |
|
Approximately once a week. If the soil feels dry, or just slightly damp, it is time to water again. Pressing a finger gently into the soil below the mulch surrounding your tree is a good indicator. If the soil is wet or very damp, wait a day or two and then test again. Overwatering kills trees, too!
| |
|
So many. A garden hose and soaker hose can be set to a timer to slowly release water for about 5 minutes. Watering tubes such as TreeGators or Ooze Tubes can be filled up about once a week. A 5-gallon bucket (with holes drilled in the sides or bottom to slowly release water) should be filled at least twice a week, and frequently moved to different areas around the root ball.

| Dutch Elm Disease: Protecting Portland's Elms
| |
| American elm (Ulmus americana) in Wallace Park
| |
|
Please remember that pruning any elm tree between April 15 and October 15 is prohibited within the City of Portland. The City Forester may waive this prohibition when it is deemed necessary to remove hazards or maintain clearance. Suckers and small branches less than 1-inch in diameter growing from the base of an elm tree may be pruned year-round.

Culture in the lab at OSU of the Ophiostoma species, a fungus that causes Dutch elm disease.
| |
|
The elm pruning moratorium is an important aspect of Portland’s Elm Protection Program. Dutch Elm Disease (DED) is lethal to American and European elms. It is caused by a fungus, Ophiostoma spp., which spreads through root grafts, elm bark beetles, and human activity. This is a particularly important time of year for DED management as elm bark beetles (vectors for fungal spores which cause DED) become active with warm and dry weather. The beetles are attracted to healthy elms with fresh wounds.

| |
| DED activities supported by this protection program include:
| |
| - Hiring a seasonal elm monitor
- Sending samples for lab analysis when symptoms appear
- Rapid removal of DED-infected elms on City property and in the right-of-way
- Proper disposal of elm wood
- Disinfection of tools and equipment
- Inoculation of healthy elms at parks, libraries, and Heritage Tree sites
- Public education on Dutch Elm Disease

| 30 Companies Attend Local Tree Care Provider Workshops
| |
|
Methods to determine when a tree permit is required, and clearance requirements for street trees.
| |
| This May, Urban Forestry held two Local Tree Care Provider Workshops. Representatives from 30 local tree care companies were in attendance!
Stay tuned for the updated list.
| |
| These workshops are an opportunity for tree professionals to come together to learn about City of Portland rules and regulations regarding our urban forest. Topics such as Title 11, recent amendments to the code, and the administrative rule for tree planting were presented along with City-specific pruning requirements.
| |
| City of Portland Approved Street Tree Planting Lists.
| |
| Companies that attend one of the workshops are eligible to be placed on the Local Tree Care Provider List after the City has verified the following information:
- An active Portland business license
- A certified arborist or registered consulting arborist on staff that attended the workshop
- No violations of the tree code within the past year
- No repeated submittals of incomplete permits
This list is a resource for Portland residents who may be seeking the services of a tree professional, and want to know which companies are knowledgeable about current industry standards and Portland’s unique protections for our trees.
If you are a tree professional and were not able to attend one of the spring workshops, we will hold another workshop in November. We hope to see you then!

| Top 5 Favorite Trees, Are Your Favorites On the List?
| |
| An informal poll here at Urban Forestry showed 5 trees that are the most popular among staff members.
| |
| The Oregon white oak (Quercus garryana) easily won the top spot.
| |
| The Douglas fir (Pseudotsuga menziesii) was right behind the oak in popularity. This particular Douglas fir is the tallest known tree in Portland, last measured at 242 feet.
| |
|
The beech tree (Fagus sp.) can have green, variegated, or copper colored leaves like this beauty over by Lair Hill Park. Photos by Steve Terrill.
| |
| The dawn redwood (Metasequoia glyptostroboides) is a deciduous conifer that sheds its needles in the winter.
| |
| 5. A tie for 5th between the ponderosa pine and the madrone
| |
|
This ponderosa pine (Pinus ponderosa) is over a hundred years old. Madrones (Arbutus menziesii) are known for their interesting red bark, which can be smooth, patchy, or shaggy.
