 Tree Care

June 11, 2022 | 10 a.m.

Speaker: John Huddleston, Owner, Precision Tree Experts

Trees are valuable! Did you know that a healthy and well-placed tree with a good structure could be worth tens of thousands of dollars...sometimes hundreds of thousands?! And think about the wildlife, aesthetics, and shade trees bring to the landscape. According to the study, the right amount of tree cover can lower summer daytime temperatures by as much as 10 degrees Fahrenheit. Let's discuss how to keep our trees healthy in this drought period and beyond.

Learn about our plant of the month:

Asclepias fascicularis – Narrowleaf Milkweed

AsclepiusDid You Know non-native Milkweed disrupts the migratory patterns of our local Monarch Butterflies? Narrowleaf Milkweed goes dormant in the winter, supporting the natural migration of the endangered Monarch species. Tropical milkweed is non-native to California and stays active all year round interrupting the natural migratory patterns of our Monarchs. When migratory patterns are interrupted, stress and illness put the species at risk. Asclepias Fascicularis can prevent the decline in the Monarch population. Growing Asclepias Fascicularis is easy, breezy, and tons of fun. From budding flowers and transforming larvae, this plant will bring you life and harmony. Native plant repopulation is up to us to restore, revalue, and regenerate. The Monarchs will thank you! (Courtesy of Moosa Creek Nursery)
