There are some avocado trees in Southern California that survive on rainfall alone. Some that I know were once part of old groves while others appear to have grown as wild seedlings from the beginning. Have they tapped into an underground water source? Are they on a particularly drought tolerant rootstock?<\/p>\n\n\n\n
Here’s a video of one such feral tree that I’ve been visiting for many years. As you’ll see, it’s having a great bloom this year despite the low rainfall we had last winter. In fact, it’s blooming better than some of the trees that I pamper with irrigation in my yard!<\/p>\n\n\n\n
