DID YOU KNOW...


…that you can conserve water and still keep your trees healthy?
 
Water-wise tree care is both possible and practical. The easiest and most efficient type of deep watering infrastructure is a drip irrigation system. Water is slowly dripped by “emitters” from a hose which allows it to be slowly absorbed into the soil. It is easy to install and there is little evaporation because it waters at the surface or under mulch. Inline drip hoses are low maintenance and easy to expand as trees grow and need additional water. The polytubing and accessories for ‘inline’ drip irrigation, including timers, are available at any garden center. 
 
Inline drip irrigation is a type of tubing with water "emitters" at even intervals inside the hose.  The tubing comes in several sizes and can be laid in concentric circles under the tree to the canopy’s outer edge, as was done for the tree in the photo at left.  How much to water depends on a variety of factors including soil, tree species and age, and weather conditions.  To help retain water and keep roots cool, spread mulch under the tree out to the tree's "drip line," i.e. the edge of its canopy.  Also, watering in the evenings or early mornings helps trees absorb water for the coming heat of the day and decreases evaporation.

 RECENT ACCOMPLISHMENTS AND EVENTS


 
Donations:
  • Five of Dr. Seuss’s The Lorax, with its message of tree care, were donated by TreeSD to Cesar Chavez Elementary School.  TreeSD’s Laurie Broedling made the formal presentation at our Parks Plus tree-planting event at Southcrest Park on November 5th as thanks to those students, staff, and parents who helped plant those new trees.
  • Sea World donated four tickets which were given to Cesar Chavez Elementary School 4th grader Ben Good.  He was selected because he has gone above and beyond in helping the school garden.

Tree San Diego Selected for
Rancho Santa Fe Forest Health Study

 
Tree San Diego has been selected by the Rancho San Fe Association to produce a significant portion of a Forest Health Study that they have newly commissioned. Spearheaded by the RSF Association Committee on the Natural Environment (CONE), this forward-thinking group has been working hard toward evaluating and documenting the overall health of their urban forest. This study will provide both baseline information on forest health and state-of-the-art information on steps to be taken by the community to enhance the health and vitality of the forest. 

Junior Tree Steward Tree-watering
Field Training on March 23rd

 
The freshness of an after-rain day added to the healthful atmosphere of school children learning how to be good tree stewards at the City of San Diego’s Morley Field Dog Park in Balboa Park. Over 100 energized Chollas Mead Elementary School 5th graders, along with 10 Urban Corps crew members, participated in field training designed to complement classroom tree-watering curriculum written by TreeSD arborists, Mel Conomikes and Rachele Melious.  Twenty-one  trees had been planted in advance by San Diego’s Park and Recreation Department, thanks to the Balboa Park Conservancy and the La Jolla Village Garden Club. This event was the capstone of our San Diego Junior Tree Steward Certification Project, accomplished with a grant from the San Diego Foundation made possible by the Opening the Outdoors Initiative and support from the Colwell Family Fund.

mulching and demonstrates correct mulching technique. 

At 10 AM, TreeSD’s Executive Director, Laurie Broedling, and Balboa Park Conservancy’s Project Committee Chair, Paul Meyer, opened the event by welcoming students, teachers, volunteers from our education partner EarthLab, Urban Corps workers, and TreeSD. The students and volunteers traveled through three stations: (1) how to water just-planted young trees, (2) how to water mature trees, and (3) hiking Florida Canyon’s nature trail.

For students and their teachers, an added bonus was Tim Lacey’s Tree Tracker presentation that showed how the students can follow their trees’ growth, learn the benefits those well-watered trees will provide -- plus gave teachers a follow-up lesson plan.

Instructors from Groundwork San Diego’s EarthLab were pre-trained by Rachele Melious and EarthLab’s Director of Education, JoAnna Proctor. They coordinated the instructors’ delivery of the lessons during the event. The students demonstrated they could apply their classroom lessons, from finding a tree’s drip line by standing under the canopy’s edge to measuring a tree’s trunk circumference using.

After a box lunch under a grove of mature trees, JoAnna assembled the students so that Laurie could present them with their Tree Steward Certificate in Novice Level Tree Watering. It was heart-warming and hopeful to see so much youthful enthusiasm focused on trees. These students will carry their experience of today into their lives and beyond – a tremendous benefit to our region and to the Earth.

UPCOMING EVENT


 
USFS’s “Every Kid in a Park”
Comes to El Centro
 
The City of El Centro is one of 10 locations selected by the US Forest Service’s Every Kid in a Park Program (EKIP) for the funding of a California Arbor Week event next month. El Centro’s event, organized and sponsored by TreeSD, will be held at Bucklin Park (the location of 44 of the 244 trees to be planted in El Centro for the Tree Advantage project, marking the half-way point in the planting of all 244 trees.) Funding for the event was made possible through a stipend from California ReLeaf and funding for the Tree Advantage project is provided by the California Department of Forestry and Fire Protection as part of the California Climate Investments Program. 
 
The event will begin with a short press conference and following that there will be a community tree planting involving students, volunteers and local government officials. Each participating 4th grade student will receive a voucher that can be redeemed as a pass to a National Park.
 
As of today, the exact date hasn’t been decided.  Stay tuned...
