Two crops of figs are potentially produced each year, for certain varieties. As not all are able to do this. Some produce the first crop and then drop off. The first or breba crop develops in the spring on last year’s shoot growth. In contrast, the main fig crop develops on the current year’s shoot growth and ripens in the late summer or fall. The main crop is generally superior in both quantity and quality to the breba crop.
From the photo you can see the large fig and many smaller figs. The large one was produced in the spring (1st crop) and the smaller ones are set in summer and are the 2nd crop. In the UK the 2nd crop may not have enough time to grow and ripen, before autumn and winter arrives. This is where growing them in tubs comes into play. I move any that have a 2nd crop into my greenhouses or conservatory to gain the extra sunshine and warmth. All of my know 2 crop varieties are grown in tubs.
