I have yellow leaves on my mission fig tree. Some immature figs. The tree is 3 years old and last year I did not get any figs that matured.

Thank you for your question. Based on the information you provided, there may be a few things happening to cause yellowing on the leaves and small immature fruits. This could be environmental stress due to either too much water, or too little water, improper drainage and lack of oxygen. Fig trees have a shallow root system and are sensitive to stress. This could also be due to a lack of nutrients. Figs originated in the Mediterranean and prefer hot and dry conditions. It may be the recent weather that is effecting your tree.
If the yellowing is not due to environmental stress but a virus, a sample will need to be taken and looked at under a microscope in order to diagnose.
The small, immature fruit size maybe be due to the Mission Fig's growth and development. It bears a first crop, called the breba crop, in the spring on last season's growth. The second crop is borne in the fall on the new growth and is known as the main crop. When pruning, prune once the tree form is established, avoid heavy winter pruning, which causes loss of the following year's crop. It is better to prune immediately after the main crop is harvested, or with late-ripening cultivars, like the Mission Fig, summer prune half the branches and prune the remainder the following summer.
