Normally Oxalis spp. start to bloom here in late September as I commence watering several weeks earlier. This year it was very hot in late summer. So, I decided not to commence the bloom season until much later. I gave the first watering in early November and bloom appeared a month later. It is glorious now with many species and the heavens have provided nearly all of the water. The benefits of doing it this way is that (1) the intense autumn hot spells in September and October that fry the plants are avoided and (2) the blooming season will be much longer. I know you people in northern California start things in August. I always started a month later and now I feel even better about delaying another month or two. This is when I want the blooms. Andrew
