It’s cold now, but warm weather earlier this winter threw off a lot of fruit trees in San Diego County. Many have leafed out & bloomed way early, like the pomegranate pictured. TSD arborist Kurt Peacock says low yields on many fruit trees are likely because of the lack of cold nights. #trees

Catkins, the pollen-producing male flowers of oak trees, are appearing early this year on many coast live oaks. In most years, the catkins usually bloom in March in San Diego County. #oaks

Living near trees may protect the heart in ways grass does not — Earth.com Cities often feel crowded, noisy, and stressful. Concrete roads and tall buildings dominate daily surroundings. Green areas offer relief and help people feel calmer and healthier.

Trees help your heart, too! A study, led by the University of California, Davis, showed that urban neighborhoods with more visible trees had lower rates of cardiovascular disease. #trees

San Diego County has had plenty of rain this winter, which is great for most trees. What it hasn't had much of is cold, & that can have negative impacts on fruit production. Many stone fruits may not meet their minimum number of "chill hours" (with temps between 32° & 45°) for good yields. #trees

Fall colors come later in San Diego County, often in December. At left is a crepe myrtle (Lagerstroemia), known as much for its colorful blooms in summer as its fall foliage. At right is a liquidambar (Liquidambar styraciflua) or sweetgum, whose leaves are shaped like maple leaves. #trees

The "radicle" is the first root to emerge from a germinating acorn. It penetrates the soil, pulls in nutrients and anchors the seedling. #oaks #trees
