Thank you for all the submissions we received for this year's flowering tree photo contest! Every tree in Portland is spectacular in its own way, but only one can win the honor given to the most stunning (and most popular) flowering tree of 2019.

We are pleased to congratulate Morgin Carpenter for winning this season's photo contest! Popular vote determined that this Magnolia x soulangeana was the photo that best captured the springtime beauty of Portland's urban forest. All photographs from the contest can be found here.
If you missed out on the spring contest, keep an eye out for the Fall Foliage contest to be announced at the end of summer. The next winning photo could be yours!

Canopy Stories: Showing in Four Portland Theaters

July 9, 10, 11, 2019. All shows start at 7:00 pm.

Only three chances left to take in a documentary about Portland's trees made in Portland! See you there!


Canopy Stories is an anthology of films produced by local filmmakers at NW Documentary that tells the stories of 12 trees in Portland.
Each film focuses on a specific tree to tell a story. The stories range from activists stationed in trees to globe-trekking botanists in search of rare specimens, as well as everyday community members transforming their neighborhoods. View the trailer for the film here.
 
Get your tickets to a July showing before they are gone!
Once you know the stories of the trees, you will never see the city in the same way.

Summer Tree Care: Watering and Mulch
A 5-gallon bucket with holes drilled in the sides for slowly watering trees. Mulch piled up against the tree trunk is bad!
A five-gallon bucket with small holes to slowly release water is an easy and affordable option for watering your trees. Mulch piled up against tree trunks is bad for trees, avoid 'mulch volcanoes.'
Even with the unusual summer rain we have had so far, the United States Drought Monitor still shows much of Multnomah County under moderate drought conditions. This could mean big trouble for little trees!
Watering and mulching young trees are known as establishment care. Helping these trees today means many rewards for our urban forest in the future!

WATERING

Watering newly planted trees for the first three to five years will help prevent a drought-related death. It will also aid in the development of a strong root system, and will help the tree develop good form with healthy branches.

Too much or too little water is bad for young trees, so here are the basics:

  • Young trees need a minimum of 15 gallons of water per week, and sometimes up to 30 gallons, depending on the weather.
  • A five-gallon bucket with three holes drilled on the side near the bottom of the bucket will deliver water slowly so that the roots get a good soaking. Use a 1/4-inch drill bit or larger to make the holes.
  • Place the bucket near the trunk of your tree with the holes facing the trunk.
  • Fill up the bucket with water three times per week during dry periods, and let the water slowly trickle into the root zone.
  • Move the bucket to a different area within the root zone of your tree each time you fill it up.

MULCHING

Properly mulching trees can help to suppress grass and weeds, and reduce competition for resources. Mulch will also help the soil retain moisture longer, so tender young roots will not dry out as fast. Lawn mower and string trimmer damage to the trunks of trees is a major problem. Mulch can help keep these tools away from the tree. Finally, as the mulch breaks down over time, it can help to create a world of beneficial microbes for the tree's root system.

Now that we know WHY we mulch, here is how to do it:

  • Remove grass and weeds within three to four feet of the base of the tree. (Take care not to damage the tree's roots, since most of the roots are found within the top 18 inches of the soil.) 
  • Start three to four inches away from the trunk, apply a layer of wood chips about three to four inches deep.
  • Extend the mulch layer out three to four feet for small trees, wider for large trees.
  • Keep mulch off the trunk of the tree! Mulch volcanoes (pictured above) invite pests and diseases.
