Once Again, Fires Threaten Giant Sequoias

The Railroad fire broke out near Yosemite on August 29.  Recent humid, cooler weather has assisted fire crews achieve 43% containment, with 12,000 acre scorched.  However, dryer conditions are expected today, with the possibility of lightening strikes. The fire is burning in an area of dry pine and cedar trees, creating difficult firefighting conditions.  Tuesday, the fire burned through Nelder Grove, containing over 100 mature giant sequoias.  Fortunately, the extremely thick bark protected the trees from damage, while all the under brush was burned. Hopefully, firefighting crews can get the upper hand on the fire and prevent further damage. Railroad … Read More

One of the Best Flowering Trees!

Back in my college days at Cal Poly Pomona, I took several plant identification courses as part of the educational requirements for Ornamental Horticulture.  Two trees from the same genus always stood out for their outstanding floral display and landscape use.  Back then, the genus was called Tabebuia, since changed to Handroanthus. The two useful landscape species are Handroanthus impetiginosa,(Pink trumpet tree) and H. chrysotrichus, (Golden trumpet tree). While taking a walk, I came across a beautiful pink trumpet tree in full bloom.  I then started noticing a few other trumpet trees scattered about the neighborhoods in North Park.  I’m not to sure why, … Read More

Worried About Your Tree?

We have gone from record drought to record amounts of snow and rain throughout California.  While the winter storms have wreaked havoc on our infra-structure (Oroville dam spillway, flooding in San Jose, etc, they have been a blessing for drought starved trees throughout the west.  Years of inadequate rainfall reduced soil moisture leading to an incredible dieback of trees numbering over tens of millions within the state. The urban environment creates stresses not normally encountered in the wild.  In cities and suburbs, trees contend with confined planter area, compacted soils, improper or inadequate irrigation, poor maintenance practices, improper pruning, shading … Read More

Trees Damaging Los Angeles Infrastructure, Who Is Responsible for Liability and Repairs?

In May and June of 2015, The Los Angeles Times published articles addressing the problem of crumbling sidewalk infrastructure within the City of Los Angeles. The articles focused on the challenges pedestrians face in this car-dominated city. After years of mounting complaints and lawsuits caused by defective, dangerous sidewalks, city officials are finally beginning to address the problems caused by trees that were planted within city parkways, medians and right of ways. After decades of deferred maintenance, the City Council, the Mayor, and public work officials are finally turning their attention toward addressing the problem, and trying to figure out … Read More

Removing Your Turf and Sprinklers Due to Drought, Remember the Trees!

As Californians scramble to find a way to reduce water consumption to meet a 25% water reduction mandate, turf removal has become the latest means to accomplish significant water savings. From Santa Barbara to San Diego, with Los Angeles and Orange county in between, turf is being ripped out at a frenzied pace. Considering the rebates offered by the Metropolitan Water District in Los Angeles and other municipalities, homeowners and businesses are jumping at the opportunity to be reimbursed for turf and spray irrigation removal.  Succulent gardens, Mediterranean, and California natives and other drought tolerant plant materials are being used … Read More

Red Trees = Dead Trees in California National Forest Lands

I recently read an article in the Los Angeles Times Drought Trees 1 , Drought Trees that addressed the tremendous die-off of trees within California’s national forests.  The aerial pictures in the article depict vast areas of red colored trees dominating the forest land.  As the drought continues, the death toll on our national forest lands is approaching record numbers. To date, scientists and U.S. Forest Service representatives estimate at least 12.5 million trees in California’s national forest have been killed due to drought. Unfortunately, scientists expect the die-off to continue as the state heads into the summer season, traditionally the driest months … Read More

Reducing Irrigation During the Drought? Don’t Forget Your Trees!

I have been getting an increased number of calls from people concerned about their tree(s) starting to dieback. They want a certified or registered consulting arborist to evaluate the tree health condition, determine the cause of the tree decline, and recommend treatment options or removal. For the past two to three years, I have noticed the increasing number of declining trees throughout San Diego. Especially noticeable is the tree dieback in the backcountry as well as local canyons and open spaces. Even drought tolerant Eucalyptus, Oak and Pines trees are struggling to survive. The cause of our tree decline and … Read More

A “Super” Way to Watch the Game!

Yesterday, while taking our usual walk through North Park heading toward Balboa park, my wife and I came across these two guys comfortably hanging out watching the Superbowl pregame show underneath towering Eucalyptus trees. They worked for a company that integrates new technologies and were promoting wireless, cable-less TV under the trees! It was really pretty nice to be able to sit under the trees on a beautiful San Diego day watching the game, best of all worlds! PS, I did inspect the trees surrounding the site for any significant defects! PSS, I don’t know anything about their company but … Read More
