Crab-apples (Malus floribunda) are of the first blossoms to test the air. A few start opening early August if it is warmish. At this time I wish for cold. Spring can be the cruellest month in South Africa. T.S. Elliott would like it here. August and September can bring harsh heat before the spring rains start - usually in mid- October. That is the biggest difference between us and most temperate climates: spring so often starts off as a stressful time for plant and human. August is the suicide month, often windy and desolate. So far so good this year: good (best ever) winter rain; cool to cold weather; little wind.
