|A mature orange tree probably does not need to be deliberately watered. The root system should be deep and wide enough to pick up the moisture it needs when other plants, trees or lawns are watered. You might try feeding your tree, though. A specially formulated citrus food will provide the nutrients your tree needs for optimum health. There are both granular forms and tree spikes. Use whichever you think will be most practical for your tree and use in amounts as recommended on the package for the size of your tree. There's not much else you can do to encourage fruit development. You can try pruning your tree back to encourage new growth which might also encourage lots of flowers later in the season. Best wishes with your tree.
