Avocado trees need well drained soil and are often planted on top of bad soil conditions by planting them on 3 foot mounds. Same can be done for anything than requires well drained soil. Then cover in deep deep mulch (wood chips are great), but respect the tree trunk, as it still needs open air (no chips 4 to 6 inches from the trunk. Weeds are controlled and water is conserved by the deep mulch, and you can water via drip line (under the mulch) if still needed (local climate and rainfall dictates that need). Living comfrey mulch is great for most trees, but citrus can be small and pretty shaded once they get large, but I would recommend a ring of comfrey right outside the deep mulch ring (don’t let the comfrey get large enough to shade the citrus, chop and drop it to keep it controlled).
Good Luck!
