Citrus trees have very shallow roots and love a good organic mulch; sugar cane and pea straw are perfect. Cover the soil generously and water down. I like to remove the mulch every time I feed the tree and replace it with fresh mulch. Do not turn the mulch into the soil because this will disturb the roots.Click to see full answer. Thereof, what kind of mulch is best for citrus trees?Organic mulch that will quickly break down is ideal for citrus because it also adds nutrients to the soil. Grass clippings, leaves, and composted vegetation are fine.Also, can you mulch around citrus trees? Orange trees can be over-mulched or mulched to close to the trunk and major roots. Outside of the area near the trunk and major roots, citrus trees benefit from a year-round layer of mulch to retain moisture, inhibit weeds, feed the soil, moderate soil temperature, and protect shallow feeder roots. Similarly, what is the best mulch to put around fruit trees? Organic matter such as straw, hay, wood chips, ground bark, sawdust, leaves, grass clippings, and pine needles are common mulching materials. These should be applied to a depth of 2 to 6 inches and cover the ground around a plant out to the drip line.Are coffee grounds good for citrus trees?Citrus do like a bit of acid soil, and are heavy feeders, meaning they use high N, as well as some P in the NPK mixes sold. Coffee grounds are probably good every 1-2 months now and 2-3 months when cooler, and are a good mulch near the trunk if dried. People, never toss coffee or tea leftovers, or even stale drinks!
